Simultaneous cochlear implantation during retrosigmoid resection of a large vestibular schwannoma under continuous electrically evoked auditory brainstem response monitoring

Hearing preservation during surgery for large vestibular schwannomas (VS) remains challenging, and reports of simultaneous cochlear implantation (CI) via the retrosigmoid approach are exceedingly rare. We report, through close collaboration between neurosurgery and otolaryngology, what is, to our knowledge, the first case of simultaneous CI during retrosigmoid resection of a large sporadic VS under continuous...

Simultaneous cochlear implantation during vestibular schwannoma resection via the retrosigmoid approach with eABR monitoring is technically feasible based on this single case, but evidence is too preliminary to change routine surgical planning.

This case contributes to a small but growing body of evidence exploring same-session tumor removal and cochlear implantation as a rehabilitation strategy for patients facing deafness after vestibular schwannoma surgery.

1. 01Single case report of simultaneous CI during retrosigmoid vestibular schwannoma resection.
2. 02Continuous electrically evoked ABR (eABR) monitoring was used intraoperatively to guide implantation.
3. 03Retrosigmoid approach was selected, allowing cochlear implant placement in the same operative field.
4. 04Findings are preliminary; no comparative outcomes data are provided.
