<div>Bone-conduction hearing aids show improvements in pure tone audiometry (PTA) gain and speech audiometry for individuals with different types of hearing loss (HL; e.g., conductive, mixed) and HL profiles (e.g., unilateral HL, bilateral HL). Results for specific devices include the following:</div> <div> <ul> <li>Ponto Percutaneous Device: Average PTA gain=34.56 dB (2 studies); Infection and skin complications reported by 45% of patients (1 study).</li> <li>BAHA Attract Passive Trascutaneous Device: Average PTA gain=28.98 dB (4 studies); Minor complications (e.g., seromas, discomfort) reported (4 studies).</li> <li>Osia Active Transcutaneous Device: Average PTA gain=37.2 dB (13 studies); Surgial complications (2 studies) and minor complications (e.g., magnet strength; 2 studies) reported.</li> <li>Bonebridge Active Transcutaneous Device: Average PTA gain=40.34 dB (7 studies); Major complications requiring explantation in 6/214 patients (7 studies).</li> <li>ADHEAR Adhesive Device: Average PTA gain=17.54 dB (4 studies); No complications reported (4 studies).</li> </ul> </div> <div>Additional research is needed to investigate candidacy indicators and device complications for individuals with hearing loss.</div>
