Otitis%20media%20-%20acute Diagnosis
Diagnosis
- Diagnosis of acute otitis media (AOM) requires a history of acute onset of signs & symptoms, signs & symptoms of middle ear inflammation, & confirmation of middle ear effusion (MEE)
History
- History alone is a poor predictor of the presence of acute otitis media (AOM)
- Signs & symptoms are usually nonspecific
- Viral upper respiratory tract infection (URTI) symptoms may be present before or during AOM
Physical Examination
Presence of middle ear effusion (MEE)
- MEE can be confirmed by direct visualization of the tympanic membrane by otoscopy or pneumatic otoscopy
- Presence of MEE is indicated by any of the following:
- Bulging tympanic membrane w/ loss of normal landmarks
- Opacification or cloudiness of tympanic membrane
- Absent or limited mobility of tympanic membrane w/ pneumatic pressure
- Otorrhea (positive purulence is associated w/ rupture of tympanic membrane)
- Air-fluid level behind the tympanic membrane
