Sub-category: Eustachian Tube Dysfunction

Symptoms:
autophony (hearing one’s own voice unusually loud); ear fullness; distorted hearing; sensation of breathing sounds in the ear

Root Cause:
The Eustachian tube remains abnormally open, disrupting the normal pressure regulation in the middle ear.

How it's Diagnosed: videos
Diagnosed through patient history, physical examination, and tympanometry, often showing abnormal compliance. The patient may report characteristic symptoms during specific postures or breathing maneuvers.

Treatment:
Treatment includes nasal saline drops, weight gain (if associated with rapid weight loss), avoiding decongestants, and surgical interventions like Eustachian tube augmentation with fillers.

Medications:
Nasal saline drops or irrigations may help maintain hydration and reduce symptoms. Occasionally, estrogen nasal sprays or tissue bulking agents are used off-label to treat severe cases.

Prevalence: How common the health condition is within a specific population.
Less common than obstructive dysfunction; occurs more often in adults and individuals with recent weight loss or hormonal changes.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Weight loss, pregnancy, radiation therapy to the head/neck, and chronic nasal decongestant use.

Prognosis: The expected outcome or course of the condition over time.
Symptoms can often be managed effectively, though some cases may require surgical correction.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic discomfort, altered quality of life, and potential progression to more severe dysfunctions requiring surgical intervention.

Airplane Ear

Specialty: Ear

Category: Eustachian Tube Disorders

Sub-category: Baro-Challenge-Induced Eustachian Tube Dysfunction

Symptoms:
ear pain or discomfort during altitude changes; a feeling of fullness in the ear; muffled hearing; dizziness; ear popping or clicking sounds; mild to moderate hearing loss; rarely, vertigo or tinnitus

Root Cause:
Occurs when the Eustachian tube fails to equalize pressure between the middle ear and the external environment, often during rapid altitude changes, such as in an airplane ascent or descent.

How it's Diagnosed: videos
Based on patient history (symptoms during altitude changes), physical examination (otoscopy revealing retracted or bulging eardrum), and possibly tympanometry to assess middle ear pressure.

Treatment:
Self-care measures (swallowing, yawning, chewing gum), nasal decongestant sprays before flight, oral antihistamines, and in severe cases, surgical intervention such as myringotomy or tympanostomy tube placement.

Medications:
Decongestants (e.g., pseudoephedrine ) to reduce nasal and sinus congestion, antihistamines (e.g., loratadine ) to alleviate allergic symptoms, and nasal corticosteroids (e.g., fluticasone ) to reduce inflammation. These medications are used to help relieve Eustachian tube dysfunction.

Prevalence: How common the health condition is within a specific population.
Common; most individuals experience mild symptoms at least once, especially during airplane travel.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Flying while having a cold or sinus infection, allergies, a naturally narrow Eustachian tube, children under 10 (due to immature Eustachian tubes).

Prognosis: The expected outcome or course of the condition over time.
Generally resolves within a few hours to days without permanent damage; symptoms may persist longer if there is an infection or significant barotrauma.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Severe barotrauma can cause middle ear bleeding, tympanic membrane rupture, or permanent hearing loss.

Scuba Diving Barotrauma

Specialty: Ear

Category: Eustachian Tube Disorders

Sub-category: Baro-Challenge-Induced Eustachian Tube Dysfunction

Symptoms:
ear pain during descent; muffled hearing; dizziness; vertigo; ear fullness; tinnitus; nosebleeds; severe cases may involve tympanic membrane rupture

Root Cause:
Results from the inability to equalize middle ear pressure with the increasing pressure in the external environment during a scuba dive descent.

How it's Diagnosed: videos
Clinical history (onset during or after diving), physical examination (otoscopy may show middle ear effusion, eardrum bulging or perforation), and audiometry to assess hearing loss.

Treatment:
Ceasing the dive to ascend slowly, self-care measures like Valsalva maneuver, medications to relieve nasal congestion, and in severe cases, medical intervention for ear drum repair.

Medications:
Decongestants (e.g., pseudoephedrine ) to relieve nasal congestion, nasal corticosteroids (e.g., mometasone ) to reduce inflammation, and sometimes antibiotics (e.g., amoxicillin ) to prevent or treat secondary infections.

Prevalence: How common the health condition is within a specific population.
Relatively common among divers, especially beginners or those diving with a cold or nasal congestion.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Poor equalization techniques, diving with nasal or sinus congestion, allergies, or having a narrow Eustachian tube.

Prognosis: The expected outcome or course of the condition over time.
Symptoms typically resolve with proper management; permanent damage is rare if barotrauma is addressed early.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Tympanic membrane rupture, secondary infections, persistent vertigo, or hearing loss in severe cases.

Autoimmune Inner Ear Disease (AIED)

Specialty: Ear

Category: Autoimmune and Systemic Conditions with Ear Involvement

Symptoms:
progressive hearing loss; tinnitus; dizziness; balance problems; ear fullness

Root Cause:
Immune system attacks the inner ear, leading to inflammation and damage to auditory and vestibular structures.

How it's Diagnosed: videos
Clinical evaluation, audiometry, imaging (MRI to rule out other causes), and response to corticosteroid treatment.

Treatment:
Corticosteroids to reduce inflammation, immunosuppressive therapies, hearing aids, or cochlear implants in severe cases.

Medications:
Corticosteroids like prednisone (anti-inflammatory) and methotrexate (immunosuppressive) are commonly prescribed.

Prevalence: How common the health condition is within a specific population.
Rare; estimated to affect 1 in 100,000 individuals annually.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Personal or family history of autoimmune diseases, middle-aged adults.

Prognosis: The expected outcome or course of the condition over time.
Variable; hearing loss may stabilize with treatment but can progress without intervention.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Permanent hearing loss, balance disorders, and reduced quality of life.

Cogan’s Syndrome

Specialty: Ear

Category: Autoimmune and Systemic Conditions with Ear Involvement

Symptoms:
interstitial keratitis; hearing loss; vertigo; tinnitus; systemic vasculitis symptoms such as fever and fatigue

Root Cause:
Autoimmune reaction targeting the eyes and inner ear, often associated with systemic vasculitis.

How it's Diagnosed: videos
Clinical history, ophthalmologic examination, audiometry, MRI to exclude other conditions, and inflammatory markers.

Treatment:
Systemic corticosteroids, immunosuppressive drugs, and supportive care for hearing and vision.

Medications:
Prednisone (corticosteroid) and cyclophosphamide (immunosuppressive) are commonly used; TNF-alpha inhibitors may be considered.

Prevalence: How common the health condition is within a specific population.
Extremely rare; fewer than 300 reported cases worldwide.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Unknown; may be linked to genetic predisposition or autoimmune conditions.

Prognosis: The expected outcome or course of the condition over time.
With prompt treatment, systemic and ocular symptoms can improve, but hearing loss may persist or progress.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Permanent hearing loss, blindness, systemic vasculitis, organ damage.
