What Is a Bone-Anchored Hearing Aid?
Bone anchored hearing aid is a device that uses bone conduction to help hearing impaired patients to enhance their hearing.

- Bone anchored hearing aid is a device that uses bone conduction to help hearing impaired patients to enhance their hearing.
- Bone anchored hearing aids are a common choice when ordinary air-conducted hearing aids are not suitable. It uses surgery to implant a titanium alloy implant in the skull. The skull will automatically fuse with the titanium alloy. The titanium alloy implant is used to directly link a special vibration generator to directly transmit sound from the bone to the inner ear to bypass the external ear And middle ear, for patients with external auditory canal and middle ear injury, ordinary air conduction hearing aids can not achieve the effect.
- There are several potential benefits of using bone anchors for hearing aids [1] . Although it is very strict, patients meet guidelines to maximize clinical benefit. However, prioritizing congenital cases is consistent with the findings of the current study. However, there is a slightly disadvantageous position in speech recognition and sound localization for patients with unilateral hearing impairment. This benefit is still uncertain
- Although the benefits are obvious, their shortcomings cannot be ignored. Soft tissue injury is currently the biggest problem for bone anchored hearing aids, and the damage to the skull by implants cannot be ignored. Titanium alloy protrudes from the skull and has a long-term wound. The risk of infection persists. To prevent infection, proper daily care is very important. Use of topical antibiotic ointment as directed by your doctor can help reduce infections.
- At present, compared with ordinary hearing aids, bone anchored hearing aids have higher costs, and in addition, the cost and risk of surgery are also greater.
