Empty Nose Syndrome & Nasal Surgery: What You Must Know First

🚨 Shattered Trust – The Complete Version is Finally Here! 🚨

After years of dedicated work, the full version of Shattered Trust – The Untold Story of Empty Nose Syndrome is now available. This high-quality, 1-hour and 25-minute investigative documentary sheds light on one of the most overlooked medical conditions of our time.

💡 About the Documentary

Every year, thousands undergo routine nasal surgeries, trusting their doctors to improve their breathing. But for some, these procedures mark the beginning of a lifelong struggle. Shattered Trust is a groundbreaking investigative documentary that exposes the hidden dangers of turbinate reduction, septoplasty, and other nasal surgeries—procedures that can lead to the devastating condition known as Empty Nose Syndrome (ENS).

Through raw patient testimonies, expert medical analysis, and in-depth research, the film uncovers how a single operation can strip away more than just nasal tissue—it can take away a person’s ability to feel air, to sleep, and to live without constant suffering. It also highlights the financial motives behind these procedures, the lack of informed consent, and the painful reality that many victims are forced to endure in silence.

For now, the full version is accessible on Patreon for a small fee to help cover the significant production costs, including AI services, avatars, voice programs, film editing software, video content, and other essential resources that made this project possible.

Why Empty Nose Syndrome Causes Severe Stress: A Full Physiological Breakdown

Empty Nose Syndrome (ENS): a complete, system-level account of why an over-open nose and lost nasal sensation produce severe stress, air-hunger and sleep disruption

Empty Nose Syndrome (ENS) develops when the nasal cavity becomes excessively wide — most commonly after turbinate reduction or conchotomy — while the nasal sensory signalling that normally reassures the brain about safe, rhythmic breathing is diminished or lost. The twin problem — a mechanically over-open airway plus absent sensory feedback (less turbulence, lower resistance, altered temperature/humidity cues and fewer mucosal vibrations) — means the brainstem no longer receives the airflow cues it relies on to confirm adequate ventilation. When those cues vanish, the brainstem treats the situation as a possible ventilation threat, triggering a neurophysiological “air-hunger” response: respiratory drive rises, sympathetic activity increases and vagal tone is reduced from the very first breaths.

But the consequences go well beyond the nose. The brisk, shallow, resistance-free breathing pattern that follows an excessively open nasal passage prevents the lungs’ slowly adapting stretch receptors (SARs), which normally stabilise rhythm, from firing adequately, while rapidly adapting receptors (RARs) — the airway “warning” sensors — are overstimulated by colder, drier and more erratic air. The net effect is an unstable breathing pattern that promotes hyperventilation and a rapid fall in arterial CO₂.

Lowered CO₂ produces hypocapnia and respiratory alkalosis, causing cerebral vasoconstriction, heightened autonomic reactivity, palpitations and a stronger subjective sensation of not getting enough air.

Concurrently, the baroreflex — the body’s primary mechanism for calming heart rate — is essentially disabled because exhalation becomes too brief to raise intrathoracic pressure enough to engage the reflex. When baroreflex gain falls, vagal influence drops, heart rate variability (HRV) declines, the sinoatrial (sinus) node becomes more excitable and the autonomic nervous system shifts into a hyper-reactive, preparedness state.

These peripheral changes also affect higher brain regions — insula, anterior cingulate cortex (ACC), amygdala and prefrontal cortex — which interpret the lack of nasal sensory input as a threat. That amplifies interoceptive monitoring, strengthens alarm responses and makes it difficult to switch into parasympathetic/rest states, especially during sleep.

Taken together, this produces a cascade of mechanical, sensory, chemical, autonomic and central-nervous system disturbances that explain why many people with ENS experience extreme physiological stress, marked functional impairment and severe sleep disturbance.

Below follows a detailed, subsystem-by-subsystem explanation of how and why this happens: the nose, the lungs, the brainstem, CO₂ regulation, baroreflex function, cardiac control and higher cortical processing.

---

1) Loss of nasal sensory input — how the brainstem is driven into an alarm state

This mechanism is the core, and it is widely misunderstood. The critical loss is not simply “airflow” but the ongoing sensory inflow that the brainstem uses to regulate breathing, autonomic tone and homeostasis. The explanation below treats anatomy, neurophysiology and sensory function in sequence.

A. Turbinates are a sensory organ — not just filters

The nasal turbinates are an active sensory component of the respiratory system. Three features make them essential:

1. They shape airflow — in a normal nose (inferior, middle and superior turbinates plus septum) the airflow is structured: local acceleration where air is forced between anatomical contours (a Venturi-like effect), generation of controlled turbulence and micro-vibrations, and predictable cooling and humidification of the mucosa. That patterned stimulus engages multiple receptor families:

• TRPM8 — sensitive to cooling/airflow; central for the subjective “airflow sensation.”

• Mechanoreceptors — detect pressure, shear, vibration and flow.

• Thermoreceptors — signal incoming air temperature.

• Moisture/osmolarity receptors — detect dryness or humidity.

2. The trigeminal V1 pathway (ophthalmic branch) carries much of this nasal sensory information. It is specialised to report cooling, flow and threat-related signals and is the main channel that tells the brain whether air is actually passing through the nose.

3. Continuous baseline signalling. Unlike sensory systems that only respond to change, nasal receptors provide tonic input on every breath — a continuous reassurance to brainstem circuits.

B. What happens when turbinates are reduced or removed?

When turbinates are reduced or a conchotomy performed, several measurable physiological consequences follow:

1. Airflow dynamics change — removing the structures that create localized acceleration and turbulence leaves a wide, relatively laminar passage. Paradoxically, the bulk airflow speed through the cavity can be lower at sensor sites: TRPM8 and mechanoreceptor stimulation declines, vibrations and turbulence diminish, and the mucosa is cooled less effectively → subjective airflow sensation decreases.

2. Pressure/resistance cues disappear — the nose normally provides resistance during inspiration, pressure gradients along the turbinates and a natural “brake” that structures inhalation. Without this, pressure differentials are minimal, depriving the brain of information about inspiratory depth and speed — a sensory vacuum forms.

3. Trigeminal input collapses — the brainstem does not simply register “different air”; it interprets the missing sensory pattern as dangerously low airflow. This is a deep-rooted protective reflex: is there cooling? is there flow? is there resistance? If the answer is no, a hardwired “air-hunger alarm” is triggered: respiratory drive rises, locus coeruleus (sympathetic arousal centre) activates, vagal activity is downregulated, vigilance increases, heart rate climbs and relaxation or sleep becomes difficult.

2) Lung mechanoreceptors — why ENS destabilises breath rhythm

Breathing rhythm is stabilised by lung mechanoreceptors; ENS alters their input indirectly but profoundly.

A. SAR — the stabiliser

Slowly Adapting Stretch Receptors (SARs) respond to slow, sustained lung inflation and provide a brake on breathing rate via vagal pathways to the nucleus tractus solitarius (NTS). They require a certain duration of inflation to fire effectively. In ENS, inhalations are faster and shorter (lower nasal resistance → shorter inspiratory phase), so SAR activation is reduced. Result: breaths become shorter and fragmented, the pre-Bötzinger rhythm destabilises and vagal tone drops — a setup for hyperventilation.

B. RAR — the rapid warning system

Rapidly Adapting Receptors (RARs) respond to abrupt pressure changes, flow, cold/dry air and irritants. They are tuned to detect sudden disruptions and to provoke faster breathing and protective reflexes. ENS allows colder, drier, less buffered air to reach airway surfaces more directly and with faster inflow; RARs fire more often and more intensely. Consequences include increased respiratory rate, sympathetic activation, stronger dyspnoea and a positive feedback loop that reinforces hyperventilation and lowers CO₂ further.

C. SAR/RAR balance is lost

Under normal conditions SAR provides calming, RAR warns as needed. ENS shifts the balance: SAR signalling falls, RAR signalling rises. The respiratory centres interpret this as inadequate expansion per breath and rapid pressure changes — prompting increased respiratory drive, unstable rhythm, reduced vagal tone and elevated heart rate with poorer HRV.

---

3) Baroreflex, intrathoracic pressure and why ENS disables a major calming reflex

The baroreflex, mediated by carotid sinus and aortic arch baroreceptors, is the body’s principal rapid brake on cardiac excitability. To engage effectively it relies on a breathing pattern that generates a slow, sustained rise in intrathoracic pressure (for example, a slow exhalation against resistance). ENS undermines this mechanism.

Intrathoracic pressure mechanics

When you exhale slowly against resistance the intrathoracic pressure rises gradually and persistently; this external pressure gently compresses the aortic arch and produces a steady stretch signal to baroreceptors. That triggers vagal output to the sinus node, slowing the heart and stabilising rhythm. Quick, resistance-free exhalation (typical in ENS) produces only a brief pressure spike that does not sufficiently stretch the vessels, so baroreceptor activation is minimal. The downstream effect: vagal tone falls, the heart loses its physiological “brake,” sympathetic tone increases, HRV drops and the body loses a powerful natural calming mechanism.

A simple analogy: the aortic arch behaves like a spring — a slow, steady press yields a strong response; a rapid tap barely moves it. ENS turns most exhalations into rapid taps.

---

4) Sinus node and whole-system autonomic disruption

The sinoatrial node (sinus node) sets heart rhythm and is modulated by the balance between sympathetic input and vagal inhibition. ENS disrupts that balance in multiple ways:

1. Loss of vagal braking — fewer vagal reflexes (e.g., weakened baroreflex) mean the sinus node becomes less inhibited, raising resting heart rate, reducing HRV and making the node more reactive to small stressors.

2. Increased sympathetic drive — the brainstem’s “air-hunger” reaction engages locus coeruleus and hypothalamic autonomic centres, increasing catecholamine tone that makes the sinus node faster and more unstable.

3. Hypocapnia effects — low CO₂ produces changes in cerebral perfusion and acid–base status and can directly destabilise cardiac electrophysiology via ion channel effects, further promoting arrhythmic susceptibility.

4. Loss of trigeminal–vagal coupling — normal breathing ties trigeminal nasal input to NTS, vagal nuclei and sinus node modulation. When nasal signalling fails, that coupling breaks and sympathetic surges dominate.

The result is a chronic internal “stress motor”: elevated baseline heart rate, exaggerated heart-rate responses to minor triggers, poor HRV, fragmented sleep and an autonomic system biased toward constant alertness.

---

5) CO₂ disturbance, the chemoreflex and why ENS can cause both acute and chronic hypocapnia

Carbon dioxide is a principal regulator of respiratory drive, cerebral blood flow and autonomic balance. ENS induces primary and secondary mechanisms that reduce CO₂.

Primary pathway

Sensorial mismatch from the nose (absent airflow signals) leads to compensatory increase in respiratory drive and faster minute ventilation → acute CO₂ washout (hypocapnia).

Immediate consequences of low CO₂

• Respiratory alkalosis → neuronal excitability, paraesthesia, muscle tension, chest discomfort.

• Cerebral vasoconstriction → reduced cerebral blood flow, dizziness, derealisation and cognitive fog.

• Cardiorespiratory symptoms → palpitations, difficulty producing a calm exhalation, chest discomfort.

Secondary adaptation

Chronic hypocapnia drives chemoreceptor adaptation: carotid body and central chemoreceptors shift sensitivity so that low CO₂ becomes the new baseline and even small CO₂ increases feel “too high,” paradoxically triggering more ventilatory drive. This chemoreflex remodelling can lock a person into a long-term hyperventilation pattern.

Chemoreflex “alarm”

When peripheral chemoreceptors are hypersensitised they rapidly convey “imbalance” signals to the brainstem, amplifying respiratory drive, sympathetic outflow and heart rate — producing what patients experience as physiological panic that cannot be suppressed by cognition alone.

---

6) Higher brain centres, interoception and the central “threat state”

ENS does not only produce peripheral dysfunctions; much of the profound distress originates in higher cortical and limbic areas that interpret bodily signals.

Insula — interoceptive integration

The insula constructs the subjective sense of breathing and internal state. When nasal sensory input disappears the insula receives a discordant picture: chest mechanics show expansion while nasal sensors signal silence → a mismatch that is interpreted as incomplete or unsafe breathing, generating persistent attention to breathing and an undefined internal air-hunger.

Anterior cingulate cortex (ACC) — mismatch detector

The ACC flags conflicts between expected and actual bodily signals; ENS creates multiple mismatches (sensory, mechanical, autonomic) that the ACC treats as errors, driving sympathetic activation, increased breathing effort and hypervigilance.

Amygdala — alarm amplification

The amygdala responds to signals suggestive of threat (air-hunger, palpitations, unstable breathing) by escalating arousal and adrenergic output. It cannot differentiate surgically produced signals from genuine external threats, so it intensifies the alarm cascade.

Prefrontal cortex — failing top-down control

The prefrontal cortex normally dampens limbic and autonomic overreactions. In ENS it is overloaded — because of poor sensory input, chemoreflex instability, sleep loss and low vagal tone — and loses efficacy at regulating the amygdala and autonomic responses. The outcome is an easily triggered stress system and poor recovery to parasympathetic states.

Interoceptive amplification

With loss of nasal input the brain weights other internal signals more heavily (chest proprioception, chemoreceptor signals, heart rate), producing heightened perception of breathlessness, chest pressure or palpitations. This mirrors phenomena seen in other sensory loss conditions (e.g., tinnitus after hearing loss).

Together these processes generate a sustained central “threat state” in which the brain perceives ongoing ventilation risk and operates in a chronic alarm mode. This is a neurophysiological cascade, not a primarily psychological disorder.

---

7) Why ENS produces major sleep disruption and nocturnal autonomic instability

Sleep requires coordinated down-regulation of arousal systems driven by vagal activation, stabilised breathing and intact sensory feedback. ENS interferes at multiple points:

1. Reduced vagal tone makes initiating and maintaining sleep difficult: the normal calming achieved via slow exhalation and baroreflex activation is absent, so heart rate remains elevated and micro-awakenings increase.

2. RAR overactivation during sleep (from cold/dry/posterior air and fluctuating flows) provokes brainstem reflexes that increase respiratory drive and fragment sleep architecture.

3. Nocturnal hypocapnia triggers cerebral vasoconstriction and sympathetic surges — frequent awakenings, palpitations and a strong air-hunger sensation upon waking are common.

4. Loss of continuous trigeminal feedback causes the brainstem arousal network (including locus coeruleus) to remain on higher readiness, so the sleeping brain is more easily woken.

5. Limbic amplification (insula, ACC, amygdala) multiplies the autonomic response to minor internal events, producing more awakenings and stronger alarm reactions.

The combined effect is a characteristic sleep phenotype: difficulty falling asleep, a readily arousable brain, high nocturnal sympathetic tone, low HRV during sleep, repeated air-hunger awakenings, lack of deep and REM sleep and marked morning fatigue. Over time this produces a near-constant hyperarousal state similar to chronic respiratory alkalosis but driven by disturbed nasal sensing and failed autonomic regulation.

---

Concluding summary

Empty Nose Syndrome sets off an interconnected cascade:

• Mechanical change (over-wide nasal cavity) + sensory loss (reduced turbulence, cooling, pressure cues) → trigeminal silence.

• Brainstem interprets missing signals as ventilation threat → respiratory drive increases → hyperventilation and CO₂ fall.

• Lung receptor imbalance (reduced SAR, overactive RAR) and chemoreflex changes destabilise rhythm.

• Baroreflex suppression reduces vagal braking → HRV falls, sinus node becomes hyperexcitable and sympathetic tone rises.

• Higher brain centres amplify threat signals and impair regulation → chronic hypervigilance and autonomic overload.

• Sleep is fragmented by nocturnal hypocapnia, RAR activation and loss of vagal stabilisation.

This is primarily a physiological syndrome — mechanical and neurophysiological — rather than a purely psychological condition. The chain of events explains why ENS patients often experience severe, persistent stress, prominent cardiorespiratory symptoms and markedly impaired sleep and daytime functioning.

Best Implant Materials for ENS Patients – Pros & Cons of Cartilage, Medpor, and Synthetic Options

1. Autologous Cartilage (Ear Cartilage or Rib Cartilage)

• What it is: Autologous cartilage refers to cartilage from your own body, typically taken from the ear or rib. It is a biological material that is often used in nasal reconstructive surgery.

• Why it’s used:

• It’s highly biocompatible because it comes from your own body, which means there’s almost no risk of rejection.

• It’s structurally stable and durable, providing long-term support for nasal structures. It is less likely to degrade or lose its shape over time, especially when placed in areas that lack strong blood flow, like the nasal septum.

• It is self-sustaining in terms of volume and structure, so it provides a lasting solution to restore the nasal shape and function in patients with ENS.

• Limitations:

• The harvesting of cartilage requires an additional surgical site (from the ear or rib), which means there is a risk of complications, such as infection or scarring.

• Bending or reshaping of the cartilage can happen over time, but this is generally minimal and slower compared to other materials.

Donor Cartilage (Cadaveric or Irradiated Cartilage)

What it is: Donor cartilage refers to cartilage harvested from cadavers, which is then processed and sometimes irradiated to reduce the risk of immune rejection. It is often used in nasal reconstruction when autologous cartilage is not available or desirable.

Why it’s used:

Donor cartilage provides a structural material similar to autologous cartilage, offering a balance between durability and biocompatibility.

Unlike ear or rib cartilage harvesting, it does not require an additional surgical site, reducing patient morbidity.

In some cases, it can be processed to maintain cellular components that promote better integration with the recipient’s tissue.

Limitations:

The processing and sterilization of donor cartilage may affect its mechanical properties, making it less resilient compared to autologous cartilage.

There is a risk of resorption or gradual breakdown over time, particularly if the cartilage does not integrate well with surrounding tissues.

Although rare, there is a small risk of immune reaction or infection despite rigorous screening and sterilization procedures.

BDCM (Biodegradable Collagen Matrix)

• What it is: 

BDCM is a collagen-based material that serves as a biodegradable matrix. Common products include Durepair (Medtronic) or Duramatrix (Stryker). It is often used in tissue reconstruction, where it provides a scaffold for new tissue growth.

• How it works:

• BDCM is designed to be temporary: It encourages the regeneration of tissue and is broken down and absorbed by the body over time. As it biodegrades, it stimulates the growth of new tissue that gradually replaces the implant.

• It is flexible and can be easily shaped to fit the exact needs of the surgery site. For ENS, it would serve as a support to restore volume and shape.

• Limitations:

• Since it breaks down over time, it doesn’t provide permanent support. In areas with low blood flow, like the space between septal mucosa and cartilage, it’s unlikely to be replaced by healthy, functional tissue, leading to loss of volume once it degrades.

• It heavily depends on vascularization and blood supply to integrate with the surrounding tissue. In poorly vascularized areas, the regenerative process might be limited, reducing the effectiveness of the implant.

Acell

• What it is: 

Acell is an extracellular matrix (ECM) material derived from animal tissues (usually porcine). It doesn’t contain living cells but is made of collagen and other proteins that promote tissue regeneration. It’s often used in wound healing and soft tissue reconstruction.

• How it works:

• Acell acts as a scaffold that encourages the growth of new tissue and angiogenesis (blood vessel formation). The body’s own cells migrate into the matrix, filling in the space and replacing the material over time.

• In nasal reconstruction for ENS, Acell would ideally encourage regeneration of mucosa and restore the volume and function of the nasal passages.

• Limitations:

• Like BDCM, Acell’s effectiveness depends on good blood flow. In low-vascular areas, the material might fail to be replaced by functioning tissue, which would cause the support to be lost over time.

• The long-term stability of Acell as a permanent support is questionable in certain areas with poor blood supply. It may not offer lasting volume and structural integrity for ENS patients.

AlloDerm

What it is: AlloDerm is an acellular dermal matrix (ADM) derived from donated human skin tissue. It is processed to remove all cells while retaining the extracellular matrix, which serves as a scaffold for tissue regeneration. AlloDerm is commonly used in reconstructive surgery, including nasal augmentation.

How it works:

AlloDerm provides a structural framework that integrates with the patient’s own tissue over time. It allows the body’s own cells to repopulate the matrix, gradually transforming it into living tissue.

It is flexible and can be shaped to fit the specific needs of nasal reconstruction, making it a useful option for restoring nasal volume and soft tissue support in ENS patients.

Limitations:

While AlloDerm integrates well with the body, it depends on adequate blood supply for successful incorporation. In poorly vascularized areas, integration may be slow or incomplete, potentially leading to resorption.

It is softer than cartilage, meaning it does not provide the same level of rigid structural support. Over time, there may be some loss of volume, particularly in high-pressure areas.

Although it is derived from human tissue, it undergoes extensive processing to remove immunogenic components, but there is still a small risk of immune response or resorption.

Integra

• What it is: Integra is another extracellular matrix (ECM) material, but it’s made up of a silicone layer on top of a collagen-glycosaminoglycan matrix. It’s primarily used in skin grafting and wound healing but also used in soft tissue reconstruction.

• How it works:

• Integra serves as a temporary scaffold for tissue regeneration. The silicone layer protects the underlying tissue while the collagen matrix promotes cell growth and encourages the formation of new tissue.

• As the material is absorbed by the body, it stimulates the growth of new, functional tissue. Integra has been shown to have good integration in areas like the skin or soft tissue, but its application in nasal surgery is still being explored.

• Limitations:

• Like Acell and BDCM, Integra depends on the blood supply in the surrounding tissue to support its regenerative process. In areas with low vascularization, its effectiveness may be limited, leading to a potential failure to regenerate the needed tissue.

• Its temporary nature means that it doesn’t provide permanent support once it breaks down.

Radiesse

• What it is: Radiesse is a dermal filler made from calcium hydroxyapatite (CaHA). It is used in cosmetic procedures to restore volume, particularly in the face, and is sometimes used for nasal volume restoration.

• How it works:

• Radiesse provides immediate volume by directly filling the tissue with calcium-based microspheres. Over time, it stimulates collagen production, which can help maintain volume even after the material is absorbed.

• It is a temporary solution, but the collagen stimulation effect means the results can last for a longer period compared to other fillers (typically 1-2 years).

• Limitations:

• Radiesse is not designed for long-term structural support like cartilage or tissue scaffolds. While it can restore volume temporarily, once it is absorbed, the volume is lost unless new tissue growth is stimulated.

• In areas like the nasal septum, with poor blood flow, Radiesse may not integrate well or regenerate tissue effectively. It doesn’t offer the same kind of permanent, natural tissue replacement as autologous cartilage or biologically regenerative materials like Acell or BDCM.

Polydioxanone (PDO) Mesh or Threads

What it is:

PDO is a biocompatible, absorbable material used in surgery and aesthetic treatments. It comes in the form of mesh or threads that can provide support and volume to the tissue.

Why it is used:

• Stimulates collagen production and can provide some long-lasting volume increase.

• Gradually absorbs while leaving behind newly formed tissue.

• Can create a mild lifting effect in the nose and restore some volume.

Limitations:

• Not a permanent solution.

• Requires good blood supply for optimal results.

Medpor (Porous Polyethylene Implant)

What it is: Medpor is a porous polyethylene structure used in facial reconstruction and has been utilized in rhinoplasty.

Why it is used:

• Provides stability and structural support.

• Integrates with the body's tissue as fibroblasts can grow into its porous structure.

Limitations:

• Can be difficult to remove if needed.

• Risk of infection if not well integrated.

Gore-Tex (Expanded Polytetrafluoroethylene, ePTFE)

What it is: A synthetic implant material used in plastic surgery for volume and structural restoration.

Why it is used:

• Biocompatible and provides long-term support.

• Softer than Medpor, which can be advantageous in some cases.

Limitations:

• Risk of infection and possible extrusion (the material being pushed out of the tissue).

• Less natural integration compared to biological materials.

Hyaluronic Acid Fillers (HA Fillers)

What it is: Hyaluronic acid (HA) fillers, such as Juvederm or Restylane, are injectable dermal fillers that temporarily restore volume by attracting water molecules to the treated area.

Why it’s used:

• Provides a non-surgical, minimally invasive method for restoring lost nasal volume in ENS patients.

• Hydrophilic properties allow for improved mucosal hydration, which may help with dryness-related ENS symptoms.

• Can be adjusted or dissolved with hyaluronidase if necessary, offering reversibility in case of undesired effects.

Limitations:

• Temporary solution, typically lasting 6-12 months before requiring re-injection.

• Not suitable for major structural defects, as it does not provide rigid support like cartilage or Medpor.

• Potential risks include lump formation, uneven distribution, and rare vascular complications if injected improperly.

Silastic (Silicone Implant)

What it is: Silastic is a medical-grade silicone commonly used in nasal implants for augmentation and reconstruction.

Why it’s used:

• Provides immediate and long-lasting volume restoration with a stable structure.

• Can be shaped and customized for specific nasal contouring needs.

• Unlike resorbable materials, it maintains its form permanently, making it an option for patients seeking a stable, long-term solution.

Limitations:

• Silicone implants have a higher risk of infection and extrusion compared to biological materials.

• It does not integrate with natural tissue and remains a foreign body, increasing the risk of displacement or migration over time.

• If complications arise, removal can be challenging and may cause additional structural damage.

Fascia Lata (Autologous Fascia Transplant)

What it is: Fascia lata is a fibrous connective tissue harvested from the thigh. It is often used in reconstructive surgery due to its strong yet flexible properties.

Why it’s used:

• Since it is autologous (from the patient’s own body), it has excellent biocompatibility with minimal risk of rejection or immune reaction.

• It provides a soft tissue augmentation option that can restore some volume in the nasal passages while allowing for some flexibility.

• It is a suitable alternative for patients who do not want cartilage grafts but need a biologically integrative material.

Limitations:

• Requires an additional surgical site (thigh), which may cause post-operative pain and scarring.

• Unlike cartilage, it does not provide rigid structural support and may resorb or shrink over time.

• The success of the graft depends on proper integration with surrounding nasal tissues, requiring sufficient blood supply.

Summary of Implant Materials for ENS

Best Long-Term Options (Most Durable & Biocompatible):

1. Autologous Cartilage (Ear or Rib Cartilage) – Gold standard due to its excellent biocompatibility, long-term stability, and resistance to degradation. Requires an additional surgical site.

2. Donor Cartilage (Cadaveric/Irradiated) – Similar to autologous cartilage but may degrade over time. No need for additional surgery, but risk of resorption exists.

3. Medpor (Porous Polyethylene) – Synthetic material that integrates with tissue, offering structural support. Lower risk of rejection than silicone but not as biocompatible as cartilage.

4. Gore-Tex (ePTFE) – Synthetic, moderately integrates with tissue but carries risk of foreign body reaction.

Temporary or Less Reliable Options:

5. BDCM (Biodegradable Collagen Matrix) & Acell (ECM material) – Promote tissue growth but require good blood supply; degrade over time and may not provide lasting volume.

6. AlloDerm (Acellular Dermal Matrix) – Integrates with tissue but can resorb in areas with poor vascularization. Softer than cartilage.

7. Radiesse (Calcium Hydroxyapatite Filler) – Temporary filler that stimulates collagen but eventually dissolves (1-2 years).

8. PDO Mesh/Threads – Stimulates collagen production but is not a permanent solution.

9. Integra (Collagen-Glycosaminoglycan Matrix with Silicone Layer) – Used for tissue regeneration but requires good blood flow, making long-term stability uncertain.

10. Silastic (Silicone Implant) – Permanent but high risk of rejection and complications, rarely used in nasal surgery today.

Best Choice for ENS Patients?

When it comes to reconstruction for ENS patients, several implant materials are available. Each option has its own advantages and disadvantages depending on factors such as biocompatibility, stability, and risk of complications.

Autologous Cartilage

Pros: The safest and most durable option. Low risk of rejection since it is the patient’s own tissue. Less prone to resorption compared to donor cartilage.

Cons: Requires an additional surgical procedure to harvest cartilage from areas like the ribs or ear.

Donor Cartilage (Cadaveric Cartilage)

Pros: A natural option with good biocompatibility and integration into the body.

Cons: Some risk of resorption over time, which may affect long-term results.

Medpor (Porous Polyethylene)

Pros: Provides strong structural support and does not resorb.

Cons: Higher risk of foreign body reaction, more difficult to remove in case of complications, and increased risk of infection.

Biodegradable Scaffolds (BDCM, Acell, AlloDerm, Integra)

Pros: Can promote tissue regeneration and be useful for soft tissue reconstruction.

Cons: Often unreliable in poorly vascularized areas, making them less effective for ENS patients.

Synthetic Materials (Silicone, Gore-Tex)

Pros: Stable and maintains its shape.

Cons: Higher risk of complications such as infections, extrusion, and tissue irritation.

Summary

Autologous Cartilage is the best and most durable option for ENS patients.

Donor cartilage is a good alternative with good biocompatibility, but it carries a moderate risk of resorption over time.

Biodegradable scaffolds may be beneficial in some cases but are often unreliable in poorly vascularized areas, such as between the mucosa and a cartilaginous or bony wall.

Synthetic Materials have the highest risk of complications and are generally less suitable for ENS patients.

Medpor can be a viable option, but it carries a risk of foreign body reaction, infection, and can be difficult to remove if complications arise
