“…Similar to Rooth et al, the prospective study by Sanna et al also showed a significant improvement in sound localization as well as subjective improvement in hearing outcomes in daily situations. 16 Taken together, these studies indicate that while open-set recognition is an important measure to consider when evaluating the efficacy of this intervention, additional outcome measures such as localization and quality of life should need to be considered.…”

“…Postoperative magnetic resonance imagings (MRIs) are routinely performed for tumor surveillance after surgery. 16,30 The receiver-stimulator and magnet distort radiographic images obtained after CI. Some considerations raised in included studies include altering placement of internal hardware to avoid distortion and avoidance of CI if there is a reasonable suspicion for residual tumor or possibility of recurrence.…”

“…Some considerations raised in included studies include altering placement of internal hardware to avoid distortion and avoidance of CI if there is a reasonable suspicion for residual tumor or possibility of recurrence. 14,16,17 In the authors' opinion, CI should only be considered if gross total resection of tumor is achieved given the challenges associated with imaging surveillance of the cerebellopontine angle ipsilateral to a CI. Further, with respect to device selection, implants compatible with MRI that do not require magnet removal prior to imaging are preferred.…”

“…Sanna et al studied 13 patients with sporadic vestibular schwannomas and normal contralateral hearing. 16 Eleven of the subjects had intrameatal tumors, and the remaining two subjects had tumors extending into the cerebellopontine angle. The authors analyzed the following postoperative performance measures with masking to the normal hearing side: pure-tone average (PTA), vowel identification, disyllabic word recognition, sentence recognition (Bocca and Pellegrini sentence list), and common phrases comprehension with a monitored live voice through the sound field at a level of 70 dB sound pressure level (SPL).…”

Translabyrinthine Excision of Vestibular Schwannoma with Concurrent Cochlear Implantation: Systematic Review

Objectives Hearing rehabilitation is an important management aspect of patients undergoing excision of vestibular schwannomas. Studies have shown cochlear implantation (CI) is possible at the time of tumor excision via a translabyrinthine approach. Primary objectives of this report are (1) to review prospective studies pertaining to outcomes of concurrent CI and translabyrinthine tumor removal in detail and (2) perform an aggregate analysis of outcomes for case reports and series. Design Systematic review based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Setting Review of literature using PubMed and Cochrane databases. Participants Eligibility included patients undergoing translabyrinthine excision of vestibular schwannoma with concurrent CI. Main Outcome Measures Open-set speech discrimination scores, sound localization, patient-reported outcome measures. Results Forty-one subjects were identified. Two prospective studies have been performed, which showed improvement in speech localization and patient-reported outcome measures. While the majority of patients achieved open set speech recognition, data pertaining to improvement in speech perception were variable. Approximately 85% of subjects had audibility with their CI. Of those that achieved open-set speech discrimination, 75% could be classified as either intermediate or high performers. The majority of low performers in open-set speech either endorsed subjective benefit or demonstrated improvement compared to preoperative measures. There was a high risk of selection and reporting bias. Conclusions The majority of patients undergoing translabyrinthine excision of vestibular schwannoma with concurrent CI achieve open set speech perception, with 75% of these patients meeting criteria for being intermediate to high performers. Additional benefits include improved subjective hearing measures, decreased tinnitus, and improved sound localization.

“…As discussed in the introduction, the benefits to CI placement in single-sided deafness are well established. 14,15 Sanna et al 27 prospectively evaluated CI placement simultaneous with translabyrinthine tumor resection with intact contralateral hearing with good results. The data gathered from this study was insufficient to evaluate the effect of an intact contralateral ear on CI outcomes with VS. As long as there is sufficient cochlear nerve function for a CI to function normally, it is reasonable to expect similar outcomes in these patients as others with singlesided deafness.…”

Cochlear Implantation in Sporadic Vestibular Schwannoma: A Systematic Literature Review

Objective This study was aimed to perform a systematic literature review by examining outcomes in patients with sporadic vestibular schwannoma (VS) undergoing ipsilateral cochlear implant (CI). Data Sources PubMed-NCBI (National Center for Biotechnology Information) and Scopus databases were searched through October 2017. Study Selection Studies reporting auditory outcomes for each patient when a CI was placed with an ipsilateral sporadic VS were included. Main Outcome Measures Demographic variables, VS characteristics, preoperative hearing metrics, duration of deafness, CI type, approach to tumor resection, postoperative auditory outcomes, and postoperative tinnitus outcomes were reported for each eligible patient within studies. Each study was evaluated for quality and bias. Results Fifteen studies and 45 patients met inclusion criteria. Mean speech discrimination score (SDS) improved from 30.0 to 56.4% after CI placement. The majority when reported had an improvement in tinnitus. Preoperative ipsilateral SDS was a negative predictor of postoperative SDS, while neither tumor resection status, tumor location, duration of deafness, ipsilateral pure tone average, nor timing of CI placement had a significant effect on patient outcome. Conclusions Notwithstanding the challenges inherent with surveillance magnetic resonance imaging (MRI) in the setting of a cochlear implant magnet, select sporadic vestibular schwannoma patients can be considered for cochlear implantation.

Objectives/Hypothesis: Hearing rehabilitation after translabyrinthine resection of a vestibular schwannoma (VS) has largely been based on the transfer of acoustic stimulus to the contralateral ear, typically through a contralateral routing of signal hearing aid or bone-anchored hearing aid (BAHA). Cochlear implant, either as a subsequent surgery or simultaneously, has become a more common treatment option; however, there is still relatively limited data available on its success. The purpose of this study is to evaluate the early outcomes of simultaneous cochlear implantation in patients with sporadic VS undergoing translabyrinthine resection.Study Design: Prospective, nonrandomized study. Methods: A prospective study of nonrandomized patients was completed at a tertiary care neurotology center. Audiologic outcomes, primarily based on AzBIO in quiet and background noise, as well as consonant-nucleus-consonant (CNC) testing of the affected ears were utilized. Tinnitus, dizziness, and spatial hearing questionnaries were also completed. Audiologic outcomes and questionnaires were compared between the pre-and postoperative groups.Results: Ten patients were included in the study with 3 month follow-up data. There was statistically significant improvement in AzBO with +10 and +5 signal to noise ratio and in quiet, as well as in CNC testing (P < .05). There was a significant improvement in Tinnitus Handicap Inventory between the two groups.Conclusions: Simultaneous cochlear implantation is a viable treatment for hearing loss after translabyrinthine approach to VS. These patients have improved hearing in background noise and tinnitus compared to their preoperative state. Further prognostic data are required to determine which patients are the best candidates.
