A new bone conduction hearing aid to predict hearing outcome with an active implanted device.

Area of Science:

• Audiology
• Biomedical Engineering
• Otolaryngology

Background:

• Bone conduction hearing devices offer solutions for hearing loss.
• Comparing active semi-implanted and passive bone conduction devices is crucial for treatment planning.

Purpose of the Study:

• To compare hearing results between an active semi-implanted bone conduction device and a new passive bone conduction hearing device.
• To evaluate the predictive value of the passive device for hearing outcomes with the semi-implanted device.

Main Methods:

• A study involving 15 patients with active bone conduction implants.
• Audiometric testing included pure tone and speech audiometry (unaided, active device, passive device).

Main Results:

• Both active and passive devices significantly improved speech reception compared to unaided listening.
• No significant difference in speech reception threshold at 100% word recognition between active and passive devices.
• Significant improvement in speech perception at lower intensities for monaural fitting with the passive device.

Conclusions:

• Hearing outcomes with active bone conduction implants align with existing data.
• The passive bone conduction device significantly enhances speech recognition.
• The passive device shows potential for predicting hearing outcomes with implanted devices, especially at higher intensities.
