C. Single-sided deafness Finbow J, Bance M, Aiken S, et al. A comparison between wireless CROS and bone-anchored hearing devices for single-sided deafness: a pilot study. Otol Neurotol . 2015; 36(5):819-825. EBM level 2........................................................................................................................148-154 Summary : This study compared outcomes with a wireless contralateral routing of signal (CROS) hearing aid to those with a bone-anchored hearing device (BAHD) in patients with single-sided deafness. A within-subject design was used to compare the two devices with regard to head shadow effect reduction, speech perception in quiet and noise, and self- assessment questionnaires. Results showed no significant difference between the two devices on either objective or subjective outcome measures. Summary : This article is a multicenter retrospective review of a cohort of pediatric and adult patients who underwent cochlear implantation for single-sided deafness of a variety of etiologies. Pre- and postoperative testing was performed using both word and sentence testing in quiet in the implanted ear alone, and sentence recognition in noise in the binaural condition. Word and sentence scores for the implanted ear alone improved significantly by 3 months postoperatively, while speech recognition in noise in the binaural condition did not change significantly. The majority of patients reported reduction in tinnitus in the implanted ear. Zeitler DM, Dorman MF, Natale SJ, et al. Sound source localization and speech understanding in complex listening environments by single-sided deaf listeners after cochlear implantation. Otol Neurotol . 2015; 36(9):1467-1471. EBM level 2.......................................................161-165 Summary : This article investigates sound localization ability and speech comprehension in complex noise environments in patients who had unilateral cochlear implantation for single- sided deafness (SSD) as compared to three control groups: normal hearing (NH) young adults, NH older adults, and bilateral cochlear implant (BCI) users. All SSD-CI users showed poorer- than-normal sound localization, typically performing as well as BCI subjects, with some subjects localizing close to the 95 th percentile of NH listeners. Speech understanding was significantly improved in ambient noise with signal presented to the CI ear in the SSD-CI listeners. McRackan TR, Wilkinson EP, Brackmann DE, Slattery WH. Stereotactic radiosurgery for facial nerve schwannomas: meta-analysis and clinical review. Otol Neurotol . 2015; 36(3): 393-398. EBM level 3........................................................................................................166-171 Summary : In this thorough meta-analysis, 10 studies are included comprising 45 patients with at least a 2-year follow up. Of these patients, 93% had tumor control, 67% had stable facial nerve function, 21% had improved function, and 13% had worsened facial nerve function. Hearing results are not as favorable. The authors conclude that stereotactic radiosurgery is an effective and reasonable option for treating facial schwannomas, though hearing loss is a substantial risk.
