Mastoiditis other diagnostic studies

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Mehrian Jafarizade, M.D [2]

Overview

Other mastoiditis imaging findings include otoscopic images of the tympanic membrane displaying middle ear effusion and infection. Also, tympanograms may be used for measuring pressure from fluid buildup in the middle ear.

Key Findings in Otoscopy in mastoiditis

Otoscopic examination of the ears may reveal the following signs indicative of mastoiditis:^[1]

Erythema of the middle ear
Presence of effusion^[2]
Bulging of the tympanic membrane in otitis media with effusion
Cloudy appearance of the tympanic membrane
Immobility of the tympanic membrane
Tympanic membrane perforation

Examples of Otoscopy in Mastoiditis

Normal tympanic membrane
Chronic otitis media
Middle ear effusion

Key Findings in Tympanometry in mastoiditis

Tympanometry may reveal hearing loss due to effusion, as measured by abnormally large reflection of sound due to elevated pressure from fluid buildup.[1]
