Sample itemWhat condition is suggested by progressive conductive hearing loss with a normal ear canal?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Otosclerosis
Otosclerosis fixes the stapes at the oval window, causing progressive conductive hearing loss despite an otherwise normal external ear canal.
Option by option
A. Meniere disease
Meniere disease causes episodic vertigo and fluctuating sensorineural loss.
B. Otosclerosis (correct)
Correct: stapes fixation in otosclerosis impairs sound conduction.
C. Labyrinthitis
Labyrinthitis causes acute vertigo with inner-ear symptoms.
D. Acoustic trauma only
Acoustic trauma usually causes sensorineural rather than conductive loss.
