Otitis Media: Symptoms, Causes & Treatment

Otitis media is an infection of the middle ear space located behind the eardrum. This small cavity contains three tiny bones responsible for sound transmission and a tube called the Eustachian tube that drains fluid and maintains air pressure. When this tube becomes inflamed due to viral or bacterial infection, fluid accumulates behind the eardrum causing severe pain and fever.

This condition is particularly common in children under 5 years of age because their Eustachian tubes are smaller in diameter and more horizontal, making fluid drainage more difficult. In the Middle East and Jordan, otitis media is among the most frequent infections in children, especially during winter when upper respiratory infections are prevalent. Most acute cases resolve on their own within days, but some require medical intervention.

Two main types exist: acute otitis media (AOM) which develops suddenly and lasts days to weeks, and otitis media with effusion (OME) where fluid persists for extended periods. This infection can temporarily affect hearing and may cause complications if left untreated.

Symptoms vary between young children and older children. Infants cannot verbally express pain and show different signs than older children. In children, symptoms typically start suddenly and are acute, especially at night. A child may first show flu-like symptoms before developing ear symptoms.

• Severe ear pain: Child may complain of severe ear pain or repeatedly tug/pull the ear forcefully (especially in infants).
• Fever: Body temperature exceeds 38°C or higher.
• Ear discharge: Parents may notice yellowish or bloody fluid draining from the ear.
• Crying and fussiness: Infants may cry continuously and feed with difficulty.
• Loss of appetite: Child may refuse food or drinks.
• Sleep disturbances: Difficulty sleeping or frequent nighttime waking.
• Temporary hearing loss: Child may not respond normally to sounds.
• Dizziness and imbalance: Older children may complain of vertigo.
• Vomiting and diarrhea: Associated gastrointestinal symptoms may occur.
• External ear redness: The external ear may appear congested.
• Swelling behind or below the ear: Lymph node enlargement.

• Viral infections: Viruses such as influenza, respiratory syncytial virus (RSV), and common cold viruses cause upper respiratory tract inflammation leading to Eustachian tube blockage.
• Bacterial infections: Bacteria including pneumococcus, meningococcus, and E. coli reach the middle ear through the blocked Eustachian tube causing bacterial infection.
• Eustachian tube obstruction: Enlarged adenoids or nasal turbinates, or severe nasal congestion prevents fluid drainage from the middle ear.
• Fluid aspiration during feeding: Improper bottle or breastfeeding positioning may allow swallowed fluid to enter the middle ear via the Eustachian tube.
• Allergies and adenoid enlargement: Seasonal or chronic allergies cause congestion leading to tube obstruction, while adenoid enlargement is very common in children.
• Barometric pressure changes: Air travel or diving can create pressure differences affecting middle ear balance.

• Age (6 months to 3 years): Peak occurrence of otitis media due to immature immune system development.
• Males more than females: Boys have higher infection rates than girls.
• Family history: Family history of ear infections increases risk.
• Daycare and schools: Children in group settings have higher exposure to infection.
• Bottle feeding: Particularly when bottle-fed in a lying position.
• Secondhand smoke: Exposure to tobacco smoke increases infection risk.
• Genetic syndromes: Children with Down syndrome or cleft palate are at higher risk.
• Immunodeficiency: Children with immune deficiencies or on immunosuppressive medications.
• Chronic allergies: Children with recurrent allergies face higher risk.
• Winter season: Upper respiratory infections are more common in cold weather.

Diagnosis is based on careful clinical examination by an ear, nose, and throat specialist or pediatrician. The doctor will inquire about symptoms and medical history, then perform a direct ear examination using specialized instruments.

• Otoscopic examination: A small device allowing the doctor to visualize the eardrum. In acute inflammation, the eardrum appears reddened and swollen with possible fluid behind it. Normal value is a grayish-pearl colored and transparent eardrum.
• Tympanometry: A painless test measuring eardrum movement and middle ear pressure. Helps detect fluid accumulation.
• Audiometry (hearing test): Doctor may order hearing tests particularly if symptoms persist or recur.
• Bacterial culture: In severe or treatment-resistant cases, fluid sample from the ear may be cultured to identify bacterial type and appropriate antibiotic.
• Ultrasound imaging: Rarely, ultrasound examination of the middle ear may be ordered.
• CT imaging: Only in cases of suspected complications.

Medications

• Pain relievers (Analgesics): Paracetamol (acetaminophen) or ibuprofen are first-line treatments for pain and fever. Dosages vary by child's weight and age. These medications relieve symptoms but don't treat the underlying cause.
• Antibiotics: Amoxicillin or amoxicillin-clavulanate are first-line choices. Used only if bacterial infection is confirmed or strongly suspected. Most viral cases don't require antibiotics. Treatment duration typically 7-10 days.
• Ear drops: Doctor may prescribe topical drops containing pain relievers like phenylephrine and benzocaine for direct pain relief.
• Decongestants: Antihistamines or nasal sprays may help reduce nasal congestion and sinus inflammation to improve Eustachian tube drainage.

Procedures and Surgery

• Tympanostomy tubes (PE tubes): In chronic cases with recurrent infections (more than 4 times yearly) or persistent fluid lasting over 3 months, surgeons can place tiny tubes through the eardrum for fluid drainage. This simple procedure is performed under brief general anesthesia.
• Adenoidectomy: If adenoids are significantly enlarged causing repeated Eustachian tube obstruction, removal may be recommended.
• Myringotomy: In severe cases with thick fluid accumulation, the doctor may make a small incision for drainage.

Lifestyle Changes and Home Care

• Adequate rest: Allow child complete rest and quiet sleep to help the body fight infection.
• Warm compresses: Applying a warm (not too hot) compress to the affected ear may relieve pain.
• Adequate hydration: Provide warm fluids (water, juice, soup) to prevent dehydration.
• Elevated head position: Sleeping with head slightly elevated may help fluid drainage from the ear.
• Prevent water entry: Keep water and shampoo out of affected ear until healed.
• Avoid irritants: Reduce exposure to smoke and pollutants that may increase nasal congestion.

• Mastoiditis: If left untreated, infection may spread to the mastoid bone behind the ear causing severe pain, swelling, and possible permanent damage.
• Meningitis: Rare but very serious complication where infection spreads to membranes surrounding the brain and spinal cord, requiring urgent hospitalization and strong antibiotics.
• Tympanic membrane perforation: Severe pressure from accumulated fluid may cause eardrum rupture. May occur naturally or require surgical intervention; eardrum usually heals spontaneously but small perforations may persist.
• Chronic hearing loss: Frequent ear infections, especially during language development years, may affect speech and language development in children.
• Labyrinthitis: Very rarely, infection may spread to the inner ear causing severe dizziness and balance loss.
• Abscess formation: In very rare cases, pus collection may develop requiring surgical drainage.
• Cholesteatoma: Extremely rare complication where abnormal skin tissue accumulates in the middle ear potentially causing progressive bone and hearing damage.

• Vaccinations: Ensure child receives all recommended vaccines, especially annual flu vaccine and pneumococcal vaccine (PCV13), which significantly reduce infection risk.
• Avoid tobacco smoke: Protect child from cigarette, hookah, and all tobacco smoke exposure; secondhand smoke increases infection risk by 37%.
• Breastfeeding: Breastfeeding provides antibodies protecting against infection. If formula feeding is necessary, bottle-feed in semi-upright position, not lying flat.
• Personal hygiene: Teach child to wash hands regularly, especially before eating and after outdoor activities, and not to play with ears.
• Avoid environmental irritants: Reduce exposure to air pollutants, smoke, and airborne particles causing nasal congestion.
• Manage allergies: Appropriately treat seasonal or chronic allergies to prevent nasal congestion.
• Relieve severe congestion: Using saline nasal spray when severely congested may help clear nasal passages.
• Avoid infected peers: Keep child away from peers with colds and flu infections when possible.
• Maintain humidity: Maintaining home air humidity at 30-50% may help prevent respiratory tract congestion.
• Regular follow-ups: Periodic check-ups with pediatrician or ENT specialist help detect problems early.
