Study Notes

Otitis Media

Otitis media (OM) refers to inflammation of the middle ear.
It's a common condition, especially in children.

Types of Otitis Media

Acute Otitis Media (AOM): rapid onset of inflammation with pain, ear discharge, headache, fever, irritability, loss of appetite, vomiting, and diarrhea.
Otitis Media with Effusion (OME): occurs after an episode of AOM. The middle ear is filled with fluid.
Chronic Suppurative Otitis Media (CSOM): Persistent ear infection that causes tearing or perforation of the eardrum.
Adhesive Otitis Media: A thinned and retracted eardrum becomes stuck to the middle ear space.

Pathophysiology of Otitis Media

Eustachian tube dysfunction (ETD) is a key factor in middle ear disease.
ETD can interfere with the mucociliary system of the middle ear, facilitating the spread of infection from the nasopharynx to the middle ear.
Esophageal contents regurgitated into the nasopharynx can cause irritation and inflammation of the middle ear via the Eustachian tube.

Symptoms of Otitis Media

Ear pain
Ear discharge
Headache
Fever
Irritability
Lethargy
Loss of appetite
Nausea/Vomiting
Diarrhea
Symptoms of an upper respiratory infection

Physical Examination of Otitis Media

The standard examination technique is pneumatic otoscopy.
It can be 90% sensitive and 80% specific for diagnosing AOM.
Color: A normal eardrum is translucent, pale gray. Opaque yellow or blue indicates middle ear effusion. Dark red suggests recent trauma or blood. Dark pink or lighter red indicates AOM or hyperemia from crying, coughing, or nose blowing.
Position: In acute otitis media (AOM), the eardrum is usually bulging. In OME, it's typically retracted or neutral.
Mobility: A slightly mobile eardrum with both positive and negative pressure indicates middle ear fluid. Lack of movement suggests perforation or a tight eardrum.
Perforation: Single perforations are common. Multiple perforations should be noted and investigated. Perforations in the posterosuperior quadrant are often associated with cholesteatoma. Pus or fluid may drain through a perforation.

Differential Diagnosis

Acute sinusitis
Bacteremia
Cholesteatoma
Colic
Diarrhea
Fever without a focus
Hearing impairment
Nasopharyngeal cancer
Otitis externa
Parainfluenza viruses

Treatment

Antimicrobials: Amoxicillin, Augmentin, Ceclor, Cefprozil, Ceftin, Suprax, Rocephin, Zithromax, Bactrim, Erythromycin.
Studies have shown no significant benefit from NSAIDs, decongestants, or antihistamines.

Otitis Media in Elderly

Elderly patients do not always present with the classic symptoms seen in children.
They may experience ear pain with or without hearing loss or signs of inflammation.
Infections can spread to adjacent structures, leading to mastoiditis, petrositis, labyrinthitis, facial nerve palsy, or intracranial complications like meningitis, abscesses, encephalitis, and venous sinus thrombosis.
