“…Cochlear patency has to be confirmed by high-resolution computed tomography or magnetic resonance imaging, because rapid and progressive osteoneogenesis can occur into the cochlea after VS resection, mainly in the labyrinthectomized ear [Chen et al, 1988;Belal, 2001]. However, as reported in the literature, cochlear implantation has been successfully performed up to 18 months after labyrinthectomy [Kveton et al, 1989;Facer et al 2000]. In our series, no ossification was observed in the 3 patients who underwent cochlear implantation in a second stage after tumor removal.…”

Objective: We aimed to evaluate and compare the auditory performance of neurofibromatosis type 2 (NF2) patients with bilateral total deafness fitted with cochlear or auditory brainstem implants. Patients and Methods: A retrospective case review was performed. Nine patients suffering from NF2 who underwent hearing rehabilitation by means of cochlear (4 patients) or auditory brainstem (5 patients) implantation participated in the study. Postoperative auditory performance was assessed using closed- and open-set tests. Results: In the group of patients fitted with a cochlear implant, 3 subjects achieved open-set speech recognition abilities comparable to those of standard adult postlingual implant patients; the remaining patient scored 0% in all open-set format tests, reporting benefits only in environmental sound detection and lip-reading. Among the 5 patients who underwent auditory brainstem implantation, 1 reached good open-set speech recognition skills, scoring 70% in the common phrases comprehension test, and she was able to communicate on the telephone. Two other patients achieved open-set speech understanding (respectively, 33 and 41% in the common phrases comprehension test), reporting daily use of their device. The remaining 2 patients did not achieve any level of open-set speech perception, obtaining only improved access to environmental sound and lip-reading skills. Conclusions: Our study confirmed literature data reporting that cochlear implantation may offer open-set speech communication in NF2 patients. In this small cohort, cochlear implant patients performed better than auditory brainstem implant patients, even if variability in auditory performance was observed with both devices. More studies are needed in order to clarify the role and reliability of electrophysiological tests in predicting the residual functionality of the cochlear nerve after tumor removal.

“…As well as avoiding the need for a second operation, this approach may avoid difficulties in implantation resulting from ossification of the cochlea after surgery (8,10,11,13). Successful implantation after labyrinthectomy has, however, been reported up to 18 months postoperatively (34,35). Successful implantation after labyrinthectomy has, however, been reported up to 18 months postoperatively (34,35).…”

“…However, recent literature has shown successful auditory rehabilitation after cochlear implantation in post-labyrinthectomy patients (Facer et al, 2000;Wareing and O'Connor, 1997). Osborn et al (2012) demonstrated that delayed implantation, even decades after labyrinthectomies, may be a viable solution for postlabyrinthectomy patients.…”
