Bone-anchored hearing implantation using the BAHA (Bone Anchored Hearing Aid) system is a surgical procedure designed to restore hearing by placing a specialized hearing device directly onto the skull bone. The BAHA system transmits sound vibrations through bone conduction directly to the inner ear, bypassing the outer and middle ear. This approach is particularly effective for specific types of hearing loss.
Indications for BAHA implantation
- Conductive or mixed hearing loss, when conventional hearing aids are ineffective due to disorders of the outer or middle ear.
- Single-sided deafness (SSD), with complete hearing loss in one ear.
- Anatomical abnormalities or medical contraindications to conventional hearing aids (e.g., external auditory canal atresia, chronic ear infections).
- Chronic middle ear diseases that prevent the use of in-ear hearing devices.
Advantages of the BAHA system
- Direct sound transmission: improved sound quality by bypassing diseased portions of the ear.
- Comfort and aesthetics: no device in the ear canal, resulting in greater comfort and discreet appearance.
- Reduced risk of infection: the ear canal remains open, lowering the likelihood of inflammation.
- Versatility: suitable for patients who do not benefit from conventional hearing aids.
How the procedure is performed
Preoperative assessment
- Diagnostics: audiometry and CT of the temporal bones to assess auditory function and bone quality.
- Consultations with an otolaryngologist and an audiologist to confirm candidacy for implantation.
Surgical procedure. Anesthesia (the operation is performed under local or general anesthesia).
Implant placement
- A small incision is made behind the ear.
- A titanium implant (screw) is inserted into the skull bone, where it integrates with the bone tissue (osseointegration).
- An abutment is attached to connect the internal implant with the external sound processor.
- Completion: the incision is closed and a sterile dressing is applied.
Postoperative period
- Healing: the osseointegration phase typically lasts 3–6 weeks.
- Care of the implant site: regular hygiene and monitoring to prevent infection.
Rehabilitation after surgery
- System activation. After complete healing, the external sound processor is fitted and activated.
- Programming and adaptation. Individual device programming by an audiologist and patient education on proper use and maintenance.
- Follow-up visits. Regular medical check-ups to monitor system performance and adjust settings if necessary.
Possible complications
- Infection at the implant site, requiring medical treatment.
- Implant failure or lack of osseointegration (rare).
- Skin reactions such as redness or irritation around the implant.
- Mechanical issues involving the sound processor or abutment.
Bone-anchored hearing implantation with the BAHA system offers an effective solution for hearing rehabilitation in selected patients. The procedure improves communication, sound perception, and overall quality of life. Modern technology and an individualized approach ensure a high level of safety, comfort, and long-term effectiveness.
The procedure is available in leading clinics in Belarus, where experienced specialists apply advanced techniques and equipment to achieve optimal clinical outcomes.
