Eustachian Tube Dysfunction in Singapore

The most common form of ETD occurs when inflammation, mucus, or structural issues prevent the Eustachian tube from opening properly. This type often results from upper respiratory infections, allergies, or sinusitis. The tube remains functionally closed, preventing proper pressure equalisation and drainage from the middle ear.

This type involves an Eustachian tube that remains abnormally open. Patients with patulous ETD may hear their own breathing and voice echoing in their affected ear (autophony). This condition may develop after weight loss, during pregnancy, or due to certain neurological conditions.

This type occurs during rapid pressure changes, such as during air travel, scuba diving, or elevator rides in tall buildings. While most people experience temporary symptoms, some individuals may develop dysfunction following these pressure changes.

• Ear fullness or sensation of clogged ears
• Slight hearing reduction or muffled sounds
• Intermittent ear popping or clicking
• Mild ear discomfort during altitude changes
• Occasional need to “pop” ears by yawning

• Persistent ear pressure lasting days
• Noticeable hearing difficulty affecting conversations
• Tinnitus (ringing or buzzing in the ears)
• Ear pain or aching sensation
• Difficulty equalising ears during flights
• Balance problems or mild dizziness

• Severe ear pain or sharp stabbing sensations
• Significant hearing loss
• Persistent vertigo or severe dizziness
• Ear discharge or signs of infection
• Complete inability to equalise ear pressure
• Development of middle ear effusion (fluid buildup)

Symptoms may worsen during upper respiratory infections, allergy seasons, or pressure changes. Symptoms are often more pronounced in the morning or during weather changes when barometric pressure fluctuates.

• Nasal Decongestants: Short-term use of decongestant sprays or oral medications may help reduce swelling in the nasal passages and Eustachian tube opening. These medications work by constricting blood vessels in the nasal tissues, potentially providing temporary relief from congestion. Treatment duration should be determined by a healthcare professional to avoid rebound congestion.
• Nasal Steroid Sprays: Prescription corticosteroid sprays may reduce inflammation in the nasal passages and around the Eustachian tube opening. These medications require consistent daily use for several weeks to achieve benefit. Steroid sprays can be used long-term safely and may be effective for patients with allergic components to their ETD.
• Antihistamines: For patients with allergic triggers, antihistamines may help control the allergic response that contributes to Eustachian tube inflammation. Both oral medications and nasal antihistamine sprays are available, with newer generation antihistamines causing less drowsiness. Treatment duration varies based on individual needs and allergy patterns.
• Antibiotics: When bacterial infection complicates ETD, causing acute otitis media or persistent effusion, antibiotics may become necessary. The choice of antibiotic depends on local resistance patterns and patient factors. Treatment duration is determined by the healthcare professional based on individual response.

• Eustachian Tube Balloon Dilation: This minimally invasive procedure involves inserting a small balloon catheter through the nose into the Eustachian tube opening. The balloon is gently inflated to stretch and widen the tube, potentially improving its ability to open and close properly. The procedure is performed under local anaesthesia and may be considered for patients with chronic obstructive ETD who haven’t responded to medical management.
• Myringotomy with Tube Insertion: For persistent middle ear fluid or recurrent ETD, creating a small incision in the ear drum and placing a ventilation tube provides an alternative pathway for pressure equalisation. The tube typically remains in place before naturally extruding. This procedure may offer relief and can help prevent fluid accumulation whilst the Eustachian tube recovers.

• Adenoidectom: Enlarged adenoids can physically block the Eustachian tube opening, particularly in children. Surgical removal of the adenoids eliminates this obstruction and may improve ETD symptoms. The procedure is performed under general anaesthesia.
• Functional Endoscopic Sinus Surgery: When chronic sinusitis contributes to ETD, endoscopic sinus surgery may be recommended to improve sinus drainage and reduce inflammation affecting the Eustachian tube. This surgical technique uses small cameras and instruments inserted through the nostrils, avoiding external incisions.

Whilst not all cases of Eustachian tube dysfunction are preventable, several strategies may help reduce your risk or prevent symptom recurrence. Managing allergies through avoiding triggers and using prescribed medications may help minimise inflammation that could affect tube function. During air travel, using earplugs designed for flying, staying hydrated, and performing regular swallowing or yawning exercises during ascent and descent may help prevent baro-induced ETD.

Maintaining good nasal hygiene through regular saline rinses may help clear mucus and allergens that could obstruct the Eustachian tube. Avoiding tobacco smoke, both first-hand and second-hand, may reduce irritation and inflammation of the respiratory passages. For those prone to ETD, treating upper respiratory infections promptly and avoiding flying when congested may help prevent acute episodes from becoming chronic problems. Regular follow-ups with your ENT specialist may help identify and address risk factors before symptoms develop.
