Name of the Procedure:

Auditory Osseointegrated Device Abutment Replacement
Common Names: Osseointegrated Hearing Device Abutment Replacement, Bone-Anchored Hearing Device Abutment Replacement
Technical Terms: Auditory Osseointegrated Device Abutment Replacement, HCPCS Code L8693

Summary

An auditory osseointegrated device works by transmitting sound vibrations directly to the inner ear via the skull bone. The abutment is a crucial component that connects the external sound processor to the implanted part of the device. This procedure involves replacing an existing abutment of any length with a new one, ensuring the proper functioning of the hearing device.

Purpose

This procedure addresses issues with the abutment, such as wear and tear, mechanical failure, or infection. The primary goal is to restore the function of the auditory osseointegrated device to improve hearing.

Indications

• Mechanical failure or malfunction of the existing abutment.
• Infection around the abutment site.
• Wear and tear causing issues in connectivity or sound transmission.
• Patient reports a decrease in device performance.

Preparation

• Pre-procedure consultation to discuss medical history and specific issues with the existing abutment.
• Any necessary imaging or hearing tests to assess the current state of the device and surrounding tissue.
• Instructions to avoid eating or drinking a few hours before the procedure if sedation is to be used.
• Review and adjustment of current medications, particularly blood thinners.

Procedure Description

1. Anesthesia: Local anesthesia is often sufficient, though sedation may be used in some cases.
2. Incision: A small incision is made around the existing abutment.
3. Removal: The existing abutment is carefully detached and removed.
4. Replacement: The new abutment is inserted and secured in place.
5. Closure: The incision is closed with sutures, and a dressing is applied.

Duration

The procedure typically takes about 30 minutes to an hour.

Setting

The procedure can be conducted in an outpatient clinic or a surgical center.

Personnel

• An otolaryngologist (ENT specialist) or a specialized surgeon.
• Surgical nurse.
• Anesthesiologist or nurse anesthetist (if sedation is used).

Risks and Complications

• Infection at the site of the new abutment.
• Bleeding or swelling.
• Pain and discomfort.
• Risk of improper fitting requiring further adjustment or replacement.
• Rare risk of damage to surrounding tissues.

Benefits

• Restored function of the auditory osseointegrated device.
• Improved hearing and quality of life.
• Generally, immediate improvement in device performance upon replacement.

Recovery

• Post-procedure care involves keeping the incision site clean and dry.
• Pain management with prescribed medications.
• The patient may experience minor discomfort or swelling.
• Follow-up appointments to monitor healing and device performance.
• Most patients can return to normal activities within a few days.

Alternatives

• Non-surgical alternatives like hearing aids, although they may not be as effective.
• Medication to manage symptoms if surgery is not an option.
• Further surgical interventions if initial replacement fails or if other complications arise.

Patient Experience

During the procedure, with local anesthesia, the patient will be awake but should not feel pain, only pressure or movement. Post-procedure, mild discomfort or pain is expected but managed with pain relief medications. The majority of patients experience a swift recovery and significant improvement in their device's functionality shortly after the replacement.
