Key Points

To describe the principal design of a direct-coupling bone-anchored hearing aid (BAHA) and assess its psychoacoustical performance and patient acceptability.
Designed a single-housing BAHA directly coupled to an osseointegrated titanium screw implanted in the mastoid portion of the temporal bone.
Evaluated the hearing system in 10 patients (N=10) using comprehensive qualitative questionnaires and speech discrimination testing.
All 10 patients (100%) preferred the BAHA over their previous hearing aids due to better comfort, aesthetic appearance, practical handling, and sound quality.
Objective speech discrimination tests showed no verified improvements in speech reception, though 6 of 10 patients (60%) reported clearly improved subjective sound quality.
The device was determined to be suitable for patients with sensorineural hearing loss up to 50–60 dB HL.
