Abstract
Background and Objectives Vestibular schwannoma (VS) itself or treatment of VS cancause single-sided deafness (SSD), a unilateral sensorineural hearing loss. Patients of SSD ex-perience communication problems, which can be frustrating. For decades, many types of boneconduction implants (BCIs) have been developed and used to treat such hearing problems. Inthis study, we evaluated the effectiveness of BAHD surgery to treat SSD patients¡¯ hearing im-pairment and analysed the complications patients suffer.

Subjects and Method A retrospective chart review was conducted on 12 patients who hadundergone BCIs, such as Baha Attract, Bonebridge, and Sophono implantation, after removalof VS. From 2016 to 2021, one senior surgeon at a single tertiary hospital performed surgeryfor SSD rehabilitation. The authors analysed the clinical features, radiologic findings (CT andMRI), hearing tests (pure tone audiogram [PTA], speech audiogram [SA], and Korea hearingin noise test), subjective satisfaction scores (abbreviated profile of hearing aid benefit), andsurgical outcomes of the patients.

Results All patients underwent temporal MRI, temporal bone CT scan, PTA, and SA atleast 3 years after VS removal and confirmed no residual tumour or serviceable contralateralhearing at the last follow-up. Among the patients (12), eight received Baha Attract implanta-tion, three received Bonebridge implantation, and one received Sophono implantation. On theaverage, patients¡¯ ipsilateral hearing outcomes improved by 82.7 dB (from 115.8¡¾9.8 dB to33.1¡¾9.5 dB).

Conclusion There are many methods of hearing rehabilitation in SSD that are used afterVS, but BCI seemed to be the most useful treatment.
