Name of the Procedure:

• Common Name(s): Behind-the-Ear (BTE) Hearing Aid, CROS Hearing Aid
• Medical Term: BTE-CROS Hearing Aid (HCPCS Code V5180)

Summary

A Behind-the-Ear (BTE) Hearing Aid, specifically the Contralateral Routing of Signal (CROS) type, is a device designed for individuals with unilateral hearing loss. It captures sound from the ear with poorer hearing and transmits it to the ear with better hearing, enabling a more balanced auditory experience.

Purpose

The primary purpose of the BTE-CROS Hearing Aid is to assist individuals with unilateral hearing loss (hearing in only one ear) by improving sound localization and overall hearing capability. This helps enhance communication and quality of life.

Indications

• Specific Symptoms/Conditions: Single-sided deafness or significant unilateral hearing loss.
• Patient Criteria: Patients with one ear with normal or near-normal hearing and one ear with significant hearing loss or deafness.

Preparation

• Pre-procedure Instructions: Ensure ears are clean and free from wax; it may be necessary to visit an audiologist for ear examination and audiometric tests.
• Diagnostic Tests: Hearing evaluation to confirm the extent of hearing loss and determine the suitability for a CROS hearing aid.

Procedure Description

1. Hearing Evaluation: Performed by an audiologist to assess baseline hearing levels.
2. Device Selection: The audiologist will recommend and custom-fit the BTE-CROS hearing aid based on individual hearing profiles.
3. Fitting and Calibration: The hearing aid devices are fitted behind the ears and calibrated to ensure optimal sound transmission.
4. Instruction: The patient is given instructions on how to use, maintain, and care for the hearing aids.

• Tools/Equipment: Audiometer, otoscope, BTE-CROS hearing aid.
• Anesthesia/Sedation: Not required, as this is a non-invasive procedure.

Duration

The entire process, including the initial evaluation, fitting, and patient instruction, typically takes 1-2 hours.

Setting

• Location: Outpatient audiology clinic or hearing center.

Personnel

• Healthcare Professionals Involved: Audiologists, hearing aid specialists, clinical support staff.

Risks and Complications

• Common Risks: Discomfort or irritation in the ear, initial difficulty in adjusting to the device.
• Rare Risks: Device malfunction, allergic reaction to materials.
• Management: Follow-up visits for adjustments, replacement parts or devices if necessary.

Benefits

• Expected Benefits: Improved hearing in noisy environments, better sound localization, enhanced ability to engage in conversations.
• Timeline: Benefits are typically realized immediately or within a few days of adapting to the hearing aid.

Recovery

• Post-procedure Care: Regular cleaning and maintenance of hearing aids, periodic check-ups with an audiologist.
• Expected Recovery Time: No recovery time needed; patients can go about their normal activities immediately.
• Restrictions: No specific restrictions; avoid exposing the hearing aids to water or extreme temperatures.

Alternatives

• Other Treatment Options: Bone-anchored hearing aids (BAHA), cochlear implants (for those with more significant hearing loss).
• Pros and Cons: BAHA and cochlear implants may provide more significant auditory benefits but are more invasive compared to non-invasive and simpler BTE-CROS hearing aids.

Patient Experience

• During the Procedure: Minimal discomfort during fitting; patient is actively engaged in testing and adjustments.
• After the Procedure: Some initial period of adjustment to the new auditory experience; mild discomfort as ears adapt to device. Pain management typically not required, but patients should report any persistent issues to their audiologist.
