Cranial nerve XII (hypoglossal nerve) palsy after arthroscopic shoulder surgery under general anesthesia combined with sono-guided interscalene brachial plexus block -A case report-

摘要

Neurologic complications after shoulder surgery may result from surgical procedures or anesthesia. Hypoglossal nerve is a pure motor nerve that supplies mylohyoid and hyoglossus muscles. Isolated hypoglossal nerve injury may be caused by direct trauma, head malposition (hyperextension or hyperflexion), and indirect compression or traction during intubation. We report a case of left hypoglossal nerve palsy after arthroscopic left shoulder surgery in the beach chair position under general anesthesia combined with brachial plexus block.
