Couldwell, William T. | Hearing restoration after resection of an intracanalicular vestibular schwannoma: a role for emergency surgery? | Patients with vestibular schwannomas (VSs) most commonly present with sensorineural hearing loss, which is often insidious or gradual. Up to 26% of patients may present with sudden hearing loss, however, which poses an important surgical challenge. Sudden hearing loss has been attributed to spasm or... | Vestibular schwannoma; Hearing preservation | 2002 |
