ABSTRACT
OBJECTIVE:
To study the auditory outcome of simultaneous translabyrinthine vestibular schwannoma (VS) resection and cochlear implantation (CI) after successful cochlear nerve preservation. STUDYDESIGN:
A retrospective case series and patient questionnaire.SETTING:
Quaternary referral center for skull base pathologies. PATIENTS Patients with small (<2âcm) sporadic or neurofibromatosis 2 related tumors were included in this study. INTERVENTION Vestibular schwannoma resectionâ+âsimultaneous cochlear implantation. MAIN OUTCOMEMEASURE:
Audiological performance postimplantation and perceived patients' benefits.RESULTS:
Forty-one patients were included. Thirty-three were sporadic VS and eight were neurofibromatosis 2. Auditory perception postimplantation was achieved in 33 patients (80.5%). At the last follow-up, 20 patients (48.8%) were users and 21 (51.2%) were nonusers. In the users' group, and after 1âyear of implant activation, vowel identification was 75.3%, disyllabic word recognition 54%, sentence recognition 60.7%, and common phrase comprehension 61%, whereas in the nonusers' group and after 1âyear of implant activation, vowel identification was 22.9%, disyllabic word recognition 14.8%, sentence recognition 15.3%, and common phrase comprehension 14%. Sixteen users were classified into 10 high performers, three intermediate performers, and three poor performers. In the user' group, the mean postimplantation pure tone average was 63.4âdB and the mean speech discrimination score was 63.7%.CONCLUSIONS:
Simultaneous CI and VS resection is a viable option with many patients achieving auditory perception and nearly half the patients are CI users at long follow-up.
