Osseointegrated Auditory Devices-Transcutaneous: Sophono and Baha Attract

Area of Science:

• Audiology
• Biomedical Engineering
• Otolaryngology

Background:

• Percutaneous osseointegrated bone conduction devices offer excellent auditory rehabilitation.
• Complications at the skin abutment interface and cosmetic concerns have driven the development of transcutaneous devices.
• Transcutaneous devices like Sophono and Baha Attract are considered cosmetically superior to percutaneous systems (Baha Connect, Ponto).

Purpose of the Study:

• To compare the safety, cosmetic outcomes, and auditory performance of transcutaneous bone conduction devices with percutaneous systems.
• To evaluate the audiological benefits and surgical considerations of transcutaneous auditory rehabilitation devices.

Main Methods:

• Review of safety and efficacy data for Sophono and Baha Attract (transcutaneous) versus Baha Connect and Ponto (percutaneous) devices.
• Comparison of auditory gain, complication rates, and patient-reported cosmetic outcomes.
• Analysis of surgical implantation procedures, including setting, sedation, operative time, and complication profiles.

Main Results:

• Transcutaneous devices (Sophono, Baha Attract) are safe and cosmetically superior to percutaneous devices.
• Transcutaneous devices provide excellent auditory enhancement but offer 5-7 dB less gain due to indirect connectivity.
• Surgical implantation is typically ambulatory, under monitored sedation, with short operative times (<1 hour) and minimal complications.

Conclusions:

• Transcutaneous bone conduction devices represent a safe and cosmetically favorable alternative for auditory rehabilitation.
• While offering slightly reduced auditory gain, their improved cosmetic profile addresses key patient concerns.
• The surgical procedure for transcutaneous devices is minimally invasive, safe, and efficient.
