Tumor Nerve of Origin and Hearing Preservation Outcomes for Patients With Small Vestibular Schwannomas Undergoing Middle Fossa Craniotomy

To evaluate hearing preservation (HP) outcomes based on tumor nerve origin for patients with small sporadic vestibular schwannomas (VS) undergoing microsurgical resection using the middle cranial fossa (MCF) approach.

Surgeons and audiologists counseling patients with small vestibular schwannomas on middle fossa craniotomy should incorporate tumor nerve of origin into pre-operative hearing preservation discussions, as it appears to predict post-surgical hearing outcomes.

Identifying tumor nerve of origin as a predictor of hearing preservation after middle fossa craniotomy could refine patient selection and surgical planning, potentially improving functional outcomes for a procedure where hearing preservation is a primary goal.

1. 01Tumor nerve of origin (superior vs. inferior vestibular nerve) is associated with differential hearing preservation rates after middle fossa craniotomy.
2. 02Study focused on small sporadic vestibular schwannomas, limiting generalizability to larger or NF2-associated tumors.
3. 03Middle fossa craniotomy is the preferred surgical route when hearing preservation is attempted in small vestibular schwannomas.
4. 04Findings published in Otology & Neurotology, a peer-reviewed specialty journal.
5. 05Results may help refine pre-operative counseling and surgical decision-making.
