Vestibular schwannoma surgery with cochlear implantation under continuous monitoring using the auditory nerve testing system: Three cases with distinct clinical scenarios

During the simultaneous resection of vestibular schwannomas and cochlear implantation, acoustic nerve preservation is essential. A recent study highlighted the effectiveness of the Auditory Nerve Test System (ANTS) for evaluating cochlear nerve function following vestibular schwannoma resection and for determining its suitability for cochlear implantation....

For select patients undergoing vestibular schwannoma resection, simultaneous cochlear implantation with continuous auditory nerve monitoring may be viable, but the three-case series is insufficient to change general practice; surgeons should view this as hypothesis-generating evidence only.

Combining tumor removal with immediate cochlear implantation under real-time nerve monitoring could expand hearing rehabilitation options for patients who would otherwise lose all residual hearing after schwannoma surgery.

1. 01Three patients underwent simultaneous vestibular schwannoma resection and cochlear implantation.
2. 02Continuous intraoperative auditory nerve monitoring via the auditory nerve testing system was used throughout.
3. 03Each case presented distinct clinical scenarios, demonstrating variability in patient selection and outcomes.
4. 04The approach may enable same-session hearing rehabilitation for carefully selected patients.
5. 05Published in Auris Nasus Larynx; sample size of three limits generalizability.
