Isolated Unilateral Hypoglossal Nerve Palsy Following Transoral Endotracheal Intubation for Endoscopic Sinus Surgery

ABSTRACT

Hypoglossal nerve palsy is a rare complication of endotracheal intubation. The mechanism of nerve palsy is mainly attributed to stretching or compression of the nerve during airway manipulation. The cuff pressure can also contribute to the occurrence of hypoglossal nerve palsy. Since it is often accompanied by other cranial nerve palsies, meticulous overall cranial nerve examination is necessary. The main treatment is supportive with respiratory monitoring. The prognosis is favorable. Majority of patients achieve nearly full recovery of nerve function. Here, we report a case of unilateral hypoglossal nerve palsy following usual, uneventful endotracheal intubation and review the literature.
