Outcome of bone-anchored hearing aids for single-sided deafness: A prospective study

Abstract Conclusion: The bone-anchored hearing aid (BAHA) system can offer significant benefits to patients with single-sided deafness (SSD), primarily by lifting the head shadow effect. Objective: To evaluate the efficacy of BAHA for SSD by comparing pre- and postoperative speech, spatial and qualities of hearing scale (SSQ) scores. Methods: This was a prospective study conducted within a tertiary auditory implant department. The inclusion criteria were unilateral profound hearing loss with normal or mild high frequency hearing loss in the hearing ear (pure tone average better than or equal to 25 dBHL measured at 0.5, 1, 2 and 3 kHz) and subjective benefits reported by patients following a home trial with a BAHA Softband. Patients who met the above criteria and opted for surgery were asked to complete the SSQ questionnaire. The postoperative SSQ response was collected after at least 6 months of consistent BAHA usage. Results: This study included 25 adult patients (mean age at implantation 57.5 years). Th...
