Question

Quizplus · Accepted Answer

The seventh cranial nerve (VII), also known as the facial nerve, innervates the muscles of facial expression. The placement of retractors during a rhytidectomy must be done carefully to avoid damaging this nerve, as it can result in facial asymmetry or even paralysis. The other cranial nerves listed (V, VI, and VIII) are not directly involved in facial movement and may be less affected by retractor placement during surgery.
