Abstract

<b><i>Background:</i></b> The ADHEAR device, a new nonsurgical bone conduction hearing device, has been developed for patients with conductive hearing loss. <b><i>Objectives:</i></b> This study aims to assess the impact of the ADHEAR device on the audiological performance and satisfaction level in subjects with conductive hearing loss. <b><i>Methods:</i></b> Twelve patients with conductive hearing loss were included. All patients received the device for 3 months. The audiological outcomes were determined using basic audiological assessments, including pure tone audiometry and sound field measurements of pure tone and speech audiometry with the contralateral ear occluded with a specific earplug. Additionally, the patients were subjectively evaluated using (1) the Speech, Spatial, and Qualities Questionnaire (SSQ), and (2) the custom-made ADHEAR questionnaire. <b><i>Results:</i></b> Analysis of the measured audiological outcomes revealed an average improvement in pure tone thresholds (functional gain) of 23 (± 4.4) dB HL when the ADHEAR system was used compared to the unaided condition in the sound field. Moreover, speech reception thresholds improved by an average of 23 (± 15.3) dB SPL in the aided condition with plugged contralateral ear. Additionally, when using ADHEAR in the sound field, subjects’ speech recognition scores improved by 32% (± 17.7) in quiet and 21% (± 15.1) in the presence of interfering noise. The average SSQ questionnaire scores improved from 3.9 at the study initiation to 6.6 after 3 months of device usage. ADHEAR custom questionnaire assessments revealed high satisfaction and acceptance of the device with no pain or skin irritation. <b><i>Conclusion:</i></b> During the study period, this new adhesive system yielded improved audiological outcomes with high patient satisfaction and acceptance and no reported skin irritation or pain.
