Question

Which nerve should be monitored closely during translabyrinthine resection of an acoustic neuroma?

a) Facial nerve
b) Vagus nerve
c) Glossopharyngeal nerve
d) Hypoglossal nerve

Answer 1

During translabyrinthine resection of an acoustic neuroma, the facial nerve should be closely monitored to prevent facial paralysis or weakness.

Step-by-step explanation:

The nerve that should be monitored closely during translabyrinthine resection of an acoustic neuroma is the facial nerve. This is because acoustic neuromas, which are benign tumors that develop on the nerve that connects the inner ear to the brain, can affect nearby nerves as they grow, particularly the facial nerve which is responsible for controlling the muscles used in facial expressions. Damage to the facial nerve during surgery can result in facial paralysis or weakness. The surgeon will closely monitor the facial nerve to prevent this complication during the procedure.
