The aim of this study is to investigate the deviced and non-deviced auditory performance results of patients with unilateral bone-anchored hearing aid. Deviced and non-deviced free field hearing thresholds, speech discrimination, and sentence discrimination scores were evaluated. Shortened profile of the benefit from the hearing instrument (Abbreviated Profile of Hearing Aid Benefit) was used. A total of 17 patients participated in the study. The mean age was 37.9 ± 17.1 years. There was a statistically significant difference between the Abbreviated Profile of Hearing Aid Benefit satisfaction questionnaire and total scores, Background Noise (BN), Reverberation (RV) subscales according to device status (P -lt; .05). No significant difference was found between the Abbreviated Profile of Hearing Aid Benefit total score result of the group divided by the hearing aid threshold (P -gt; .05). No significant difference was found between the Abbreviated Profile of Hearing Aid Benefit total score result of the group divided by the threshold without a hearing aid (P -gt; .05). Bone-implanted hearing aids are effective and reliable amplification methods in patients with conductive and mixed hearing loss. Positive results of patient satisfaction and evaluation inventories were obtained from this study.
