Lower cranial nerve palsy after the infrafloccular approach in microvascular decompression for hemifacial spasm

摘要

Background:The infrafloccular approach was introduced as a variation in microvascular decompression (MVD) for hemifacial spasm. However, the rate of postoperative lower cranial nerve (CN) palsy can be high. This study investigated the surgical factors in relation to the occurrence of postoperative lower CN palsy.
