Suppurative Otitis Media (SOM)

Overview

Suppurative otitis media, also called acute purulent otitis media, is an infection of the middle ear that produces pus (purulent fluid) behind the tympanic membrane. It is a common complication of acute otitis media, especially in children, and can lead to pain, fever, hearing loss, and, if untreated, spread of infection to nearby structures.

Most cases are caused by bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Viral upper‑respiratory infections often precede the bacterial invasion.

Symptoms Checklist

• Ear pain (often severe) – especially when lying down
• Feeling of fullness or pressure in the ear
• Fever (≥38 °C / 100.4 °F)
• Otorrhea – pus‑filled drainage from the ear (may be after tympanic membrane perforation)
• Hearing loss or muffled hearing
• Vertigo or balance disturbances (less common)
• Irritability or crying in infants
• Headache

[2] CDC, “Acute Otitis Media”

Risk Factors

• Age < 5 years – eustachian tube is shorter and more horizontal
• Recent upper‑respiratory infection (cold, flu)
• Day‑care attendance or exposure to other children
• Exposure to tobacco smoke (second‑hand)
• Allergic rhinitis or chronic sinusitis
• Use of pacifiers in infants
• Impaired immune system (e.g., HIV, chemotherapy)
• Anatomical abnormalities of the ear or eustachian tube

Diagnosis

Diagnosis is primarily clinical, performed by a health‑care professional using otoscopy and a focused history.

• Otoscopy: Redness, bulging, or perforation of the tympanic membrane; presence of pus or fluid behind the membrane.
• Tympanometry: Measures middle‑ear pressure; often shows a “flat” trace in acute infection.
• Audiometry: Baseline hearing test if hearing loss is suspected.
• Culture of ear discharge: Reserved for cases that do not improve with first‑line therapy or when atypical organisms are suspected.
• Imaging (CT/MRI): Rarely needed, only if complications such as mastoiditis or intracranial spread are suspected.

Treatment Options

Medical Management

• Antibiotics: First‑line oral agents include amoxicillin‑clavulanate or high‑dose amoxicillin; alternatives for penicillin‑allergic patients are cefdinir or azithromycin. Duration is usually 7–10 days.
  [1]
• Pain control: Acetaminophen or ibuprofen for fever and pain. Topical analgesic drops may be used if the tympanic membrane is intact.
• Corticosteroid ear drops: Occasionally added to reduce inflammation, especially in chronic or recurrent cases.
• Myringotomy with tube placement: Indicated for recurrent or persistent effusion, severe pain, or risk of hearing loss.

Home Care & Supportive Measures

• Warm compresses over the affected ear for 10–15 minutes, 3–4 times daily.
• Maintain adequate hydration and rest.
• Elevate the head of the bed to improve eustachian tube drainage.
• Avoid water entry into the ear (use ear plugs while bathing) until the infection resolves.

Prevention

• Breastfeed infants for at least 6 months – provides protective antibodies.
• Limit exposure to tobacco smoke and other indoor pollutants.
• Keep vaccinations up to date (influenza, pneumococcal, Haemophilus influenzae type b).
• Practice good hand hygiene to reduce viral upper‑respiratory infections.
• Use of prophylactic antibiotics is not routinely recommended; only in select high‑risk children under specialist guidance.

Living With Suppurative Otitis Media

• Monitor hearing: Schedule periodic audiograms if infections are recurrent.
• Follow‑up appointments: Ensure the ear has healed; check for residual perforation or fluid.
• Ear protection: Use swimmer’s ear plugs during water activities after the infection clears.
• School & daycare: Keep children home if they have fever or drainage to prevent spread.
• Medication adherence: Complete the full antibiotic course even if symptoms improve.
• Maintain a symptom diary to discuss patterns with your clinician.

When to Seek Emergency Care

Call 911 or go to the nearest emergency department if you notice any of the following:

• Sudden severe ear pain with high fever (>39 °C / 102 °F) that does not improve with medication.
• Rapid swelling or redness behind the ear (possible mastoiditis).
• Neurological symptoms: facial weakness, severe headache, vomiting, confusion, or vision changes.
• Persistent drainage of pus despite 48 hours of appropriate antibiotics.
• Signs of allergic reaction to medication (hives, swelling of lips/tongue, difficulty breathing).
