Sample itemWhich feature distinguishes otitis externa from acute otitis media?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Pain on tragal movement
Otitis externa inflames the canal, so movement of tragus or pinna is painful, unlike middle-ear infection where otoscopy shows tympanic changes.
Option by option
A. Conductive loss from ossicular fixation
Ossicular fixation suggests otosclerosis.
B. Middle-ear effusion
Effusion is middle-ear disease.
C. Pain on tragal movement (correct)
Correct: canal manipulation causes external-ear pain.
D. Bulging tympanic membrane
Bulging drum suggests otitis media.
