Aetiology: mostly viral.
Clinical picture:
Pain and fullness in the ear are common. The drum and sometimes the deep meatus show hyperemic bullae. The bullae can rupture spontaneously, causing a small amount of serous or serosanguineous drainage. Sensorineural hearing loss has been found in up to one-third of affected patients (? Viral).
Diagnosis:
Diagnosis is made mainly by pneumatic otoscope to show the movement of the drum carrying the bullae. This differentiates it from the bulging hyperemic drum in acute otitis media which does not move.
Treatment:
Symptomatic treatment, an audiogram should be performed.
