What hearing problems are associated with cleft palate, and why do they occur?

• A. Sensorineural hearing loss due to inner ear malformations
• B. Otitis externa due to canal abnormalities
• C. Otitis media with effusion and conductive hearing loss due to Eustachian tube dysfunction and middle ear fluid
• D. No hearing problems are associated

Answer: (C)

The key idea is that cleft palate often disrupts how the Eustachian tube works. The muscles that help open this tube don’t function normally when a cleft is present, so the tube can’t aerate the middle ear or drain fluid effectively. This leads to fluid buildup behind the eardrum, known as otitis media with effusion. The fluid dampens sound transmission, producing conductive hearing loss. Because this middle-ear issue is tied to the structural and muscular abnormalities of cleft palate, it’s the most common hearing problem seen in these patients.

Otitis externa, an infection of the external ear canal, isn’t typically linked to cleft palate and thus isn’t the usual hearing problem here. Sensorineural hearing loss would involve the inner ear or auditory nerve, which isn’t the typical consequence of cleft palate. And saying there are no hearing problems contradicts the well-established association between cleft palate and middle-ear dysfunction with effusion.
