A 25-year-old pregnant woman comes to the clinic complaining of unilateral hearing loss. The woman says her mother lost her hearing when she was pregnant. What would you suspect the patient has?
A) Otosclerosis
B) Ossiculitis
C) Mastoid disease
D) Chronic otitis media
Ans: A
Feedback: Otosclerosis involves the stapes and is thought to result from the formation of new, abnormal spongy bone, especially around the oval window, with resulting fixation of the stapes. The efficient transmission of sound is prevented because the stapes cannot vibrate and carry the sound as conducted from the malleus and incus to the inner ear. Otosclerosis is more common in women and frequently hereditary, and pregnancy may worsen it. In the scenario described nothing is suggestive of chronic otitis media or mastoid disease. Ossiculitis is a distracter for this question.
