Understanding the Translabyrinthine Approach for Neurosurgery Residents: Operative and Educational Video.

ABSTRACT: Vestibular schwannomas are benign tumors of the vestibular division of the eighth cranial nerve, with an incidence of 1 to 2 per 100,000 annually. Large tumors (>3 cm) may cause disabling symptoms such as progressive hearing loss, vestibulopathy, or trigeminal nerve dysfunction, often necessitating microsurgical resection. This video demonstrates the translabyrinthine resection of a 3.2-cm left-sided vestibular schwannoma in a 67-year-old woman with worsening sensorineural hearing loss and new-onset lip numbness ( Video 1 ). The procedure was performed at a tertiary center with continuous intraoperative neurophysiological monitoring of cranial nerves V, VI, VII, X, and XI, as well as somatosensory and motor evoked potentials. Near-total resection (∼99%) was achieved, with a small residual
