Background: Contralateral sudden sensorineural hearing loss (SNHL) after vestibular schwannoma (VS) surgery is extremely rare, and the mechanism of hearing loss remains unclear. This report aims to provide details of a new case of contralateral SNHL after VS resection, discuss the possible causes of SNHL, and review the relevant literature.
Case description: A 32-year-old woman developed sudden, profound SNHL after VS surgery. She gradually recovered partial hearing after 6 months of steroid, vasodilator, and neurotrophic therapy.
Conclusions: Compensatory endolymphatic hydrops caused by the loss of cerebrospinal fluid might be responsible for this case of sudden SNHL following VS surgery.
