Acute otitis media (AOM) is a common bacterial infection of the middle ear, often occurring as a complication of upper respiratory tract infections, such as the common cold or flu.

It is characterized by the rapid onset of symptoms such as ear pain, fever, irritability (especially in infants), and sometimes hearing loss. Prompt diagnosis and appropriate treatment are essential to relieve symptoms, prevent complications, and promote recovery. Here’s an overview of the diagnosis and treatment of acute otitis media:
Diagnosis:
- Medical History: The healthcare provider will inquire about the individual’s symptoms, including ear pain, fever, recent upper respiratory tract infection, and any history of previous ear infections.
- Physical Examination:
- Otoscopy: Examination of the ear canal and eardrum using an otoscope to assess for signs of inflammation, redness, bulging of the tympanic membrane, and presence of fluid or pus.
- Tympanometry: Measurement of the mobility and pressure in the middle ear to evaluate the function of the eardrum and middle ear space.
- Diagnostic Criteria:
- Presence of acute onset of symptoms (e.g., ear pain, fever) lasting less than three weeks.
- Otoscopic findings consistent with acute inflammation of the middle ear, such as bulging tympanic membrane, erythema, or middle ear effusion (fluid).
Treatment:
- Pain Management:
- Analgesics: Use over-the-counter pain relievers such as acetaminophen or ibuprofen to alleviate ear pain and reduce fever. Avoid aspirin in children due to the risk of Reye’s syndrome.
- Ear Drops: Administer topical ear drops containing analgesics (e.g., benzocaine) or numbing agents to relieve ear pain. Follow the manufacturer’s instructions for proper administration.
- Antibiotic Therapy:
- Antibiotics are often prescribed for moderate to severe cases of AOM, particularly in children under two years of age or those with persistent or severe symptoms.
- First-line antibiotics: Amoxicillin is the first-line antibiotic choice for uncomplicated AOM in children, given its effectiveness against Streptococcus pneumoniae and Haemophilus influenzae.
- Alternative antibiotics: If the child has a history of amoxicillin allergy or treatment failure, alternative antibiotics such as amoxicillin-clavulanate, cefuroxime, or ceftriaxone may be prescribed.
- Duration: Antibiotic treatment typically lasts for 5-7 days, although shorter courses (e.g., 3 days) may be effective in certain cases.
- Observation without Antibiotics:
- In certain situations, such as mild AOM in older children or when the diagnosis is uncertain, healthcare providers may recommend observation without immediate antibiotic treatment.
- Close follow-up is essential to monitor symptom progression and initiate antibiotic therapy if symptoms worsen or fail to improve within 48-72 hours.
- Other Measures:
- Warm Compress: Apply a warm compress or heating pad to the affected ear to relieve pain and promote comfort.
- Nasal Decongestants: Use nasal decongestants (e.g., saline nasal spray) to alleviate nasal congestion and improve Eustachian tube function, facilitating drainage of fluid from the middle ear.
Follow-Up:
- Schedule a follow-up appointment with the healthcare provider to monitor the individual’s response to treatment, assess for resolution of symptoms, and evaluate the eardrum for signs of improvement or complications.
- Additional treatment or referral to an otolaryngologist (ear, nose, and throat specialist) may be necessary for recurrent or persistent cases of AOM, complications such as mastoiditis or hearing loss, or when initial treatment fails.
By following these diagnostic and treatment guidelines, healthcare providers can effectively manage acute otitis media, alleviate symptoms, prevent complications, and promote the individual’s recovery. It’s essential for caregivers to adhere to treatment recommendations, administer medications as prescribed, and seek medical attention if symptoms worsen or do not improve within the expected timeframe.
