ENT · Ear and audiology: tuberculous otitis media
Sample itemA young man on treatment for pulmonary tuberculosis develops painless thin ear discharge with a rapid fall in hearing. Pale granulations are seen in the middle ear. Which drum finding is characteristic?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Multiple small perforations
Tuberculous otitis media classically gives painless watery otorrhoea, pale granulations, early severe hearing loss and multiple small drum perforations that coalesce. Facial palsy and mastoid sequestra can follow. Diagnosis needs culture, PCR or histology of granulations.
Option by option
A. A posterosuperior retraction pocket
A posterosuperior retraction pocket suggests eustachian tube dysfunction progressing to cholesteatoma.
B. A single large central perforation
A single large central perforation is typical of the safe type of chronic suppurative otitis media.
C. Multiple small perforations (correct)
Correct. Multiple small perforations that coalesce are the hallmark of tuberculous otitis media.
D. A marginal attic perforation
A marginal attic perforation suggests cholesteatoma in the unsafe type of chronic suppurative otitis media.
