Audiological and clinical outcomes of a transcutaneous bone conduction hearing implant: Six‐month results from a multicentre study

Objectives To compare the hearing performance of patients with conductive and mild mixed hearing loss and single‐sided sensorineural deafness provided with a new transcutaneous bone conduction hearing implant (the Baha Attract System) with unaided hearing as well as aided with a sound processor on a...

Description
Summary:Objectives To compare the hearing performance of patients with conductive and mild mixed hearing loss and single‐sided sensorineural deafness provided with a new transcutaneous bone conduction hearing implant (the Baha Attract System) with unaided hearing as well as aided with a sound processor on a softband. Furthermore, to evaluate safety and subjective benefit before and after implantation of the test device. Participants Fifty‐four adult patients in five participating centres were enrolled in this prospective study. Baseline data were collected during a pre‐operative visit, and after a softband trial, all patients were implanted unilaterally. Follow‐up visits were scheduled at 10 days, 4, 6, 12 weeks and 6 months. Main outcome measures. Free‐field hearing thresholds pure‐tone average (PTA4 in dB HL; mean threshold at 500, 1000, 2000, 4000 Hz; primary outcome measure). Individual free‐field hearing thresholds, speech recognition in quiet and in noise, soft tissue status during follow‐up and subjective benefit as measured with the Abbreviated Profile of Hearing Aid Benefit (APHAB), Speech, Spatial and Qualities of Hearing Scale (SSQ) and Health Utilities Index (HUI) questionnaires. Results Implantation of the Baha Attract System resulted in favourable audiological outcomes compared to unaided conditions. On the primary outcome parameter, a statistically significant improvement was observed compared to unaided hearing for the patients with conductive/mixed hearing loss (mean PTA4 difference −20.8 dB HL, SD 9.8; P
