Name of the Procedure:

Auditory Osseointegrated Device (L8690)

Summary

An auditory osseointegrated device is a hearing implant that includes both internal and external components. It helps individuals with hearing loss by transmitting sound directly to the inner ear via bone conduction, bypassing damaged parts of the auditory system.

Purpose

The procedure is designed to improve hearing for individuals with conducive or mixed hearing loss, single-sided deafness, or certain other ear conditions. The main goal is to enhance sound clarity and improve overall communication abilities.

Indications

• Conductive or mixed hearing loss
• Single-sided deafness
• Chronic ear infections
• Patients who cannot wear traditional hearing aids due to ear malformations or severe allergies

Preparation

• Fasting may be required if general anesthesia is used.
• Pre-operative assessments such as hearing tests, CT scans, or MRIs.
• Medication adjustments as recommended by the physician.

Procedure Description

1. Administer anesthesia (local or general, depending on the case).
2. The surgeon makes a small incision behind the ear.
3. A small titanium implant is drilled and fixed into the skull bone.
4. The surgical site is closed and allowed to heal (osseointegration period).
5. After several weeks, the external sound processor is attached to the implant.

Duration

The surgery typically lasts about 1 to 2 hours.

Setting

The procedure is usually performed in a hospital or outpatient surgical center.

Personnel

• Otolaryngologist (ENT surgeon)
• Anesthesiologist
• Surgical nurses
• Audiologist (for post-surgical adjustment)

Risks and Complications

• Infection at the surgical site
• Implant failure or rejection
• Skin irritation around the implant
• Numbness or pain around the implant area

Benefits

• Significant improvement in hearing ability.
• Better sound quality and clarity.
• Improved communication and quality of life.
• Benefits can often be realized shortly after the device is activated.

Recovery

• Initial healing period of 2 to 4 weeks.
• Follow-up appointments for sound processor adjustments.
• Avoid strenuous activities and heavy lifting for a specified period.
• Careful hygiene around the surgical site to prevent infection.

Alternatives

• Traditional hearing aids: non-invasive but may not be suitable for all types of hearing loss.
• Cochlear implants: for more profound hearing losses but involve a more complex surgery.
• Bone-anchored hearing aids: similar to osseointegrated devices but with different attachment methods.

Patient Experience

Patients might feel some discomfort or pain post-surgery, which can be managed with prescribed pain relievers. They may also experience a sensation of tightness or pressure around the implant site during the healing process. The initial period without the external processor might require some adjustment, but most patients find significant improvement in hearing once it is attached and activated.
