Abstract

Objective

To present our data evaluating the feasibility of simultaneous cochlear implantation with resection of acoustic neuroma.

Methods

This paper describes a case series of eight adult patients with a radiologically suspected acoustic neuroma, treated at a tertiary referral centre in Newcastle, Australia, between 2012 and 2015. Patients underwent cochlear implantation concurrently with removal of an acoustic neuroma. The approach was translabyrinthine, with facial nerve monitoring and electrically evoked auditory brainstem response testing. Standard post-implant rehabilitation was employed, with three and six months’ follow-up data collected. The main outcome measures were: hearing, subjective benefit of implant, operative complications and tumour recurrence.

Results

Eight patients underwent simultaneous cochlear implantation with resection of acoustic neuroma over a 3-year period, and had 25–63 months’ follow up. There were no major complications. All patients except one gained usable hearing and were daily implant users.

Conclusion

Simultaneous cochlear implantation with resection of acoustic neuroma has been shown to be a safe treatment option, which will be applicable in a wide range of clinical scenarios as the indications for cochlear implantation continue to expand.
