92558 Evoked otoacoustic emissions, screening (qualitative measurement of distortion product or transient evoked otoacoustic emissions), automated analysis

Name of the Procedure:

Evoked Otoacoustic Emissions, Screening (Qualitative Measurement of Distortion Product or Transient Evoked Otoacoustic Emissions), Automated Analysis

Summary

This procedure is a quick and non-invasive hearing test used to screen for hearing loss, especially in newborns and young children. It involves measuring sound waves produced in the inner ear in response to auditory stimuli.

Purpose

The procedure helps to:

• Detect hearing loss early.
• Ensure proper auditory development.
• Facilitate timely intervention if hearing issues are present.

Indications

• Newborn hearing screening.
• Screening for hearing loss in infants and young children.
• Follow-up testing for children who did not pass initial hearing screenings.

Preparation

No special preparation is needed for this procedure.

Procedure Description

1. The patient, typically an infant or young child, sits or lies comfortably.
2. A small probe is placed in the ear canal.
3. The probe emits sounds and measures the echo that responds from the inner ear.
4. The data is analyzed automatically by the equipment to provide results.

The procedure is painless and does not require anesthesia or sedation.

Duration

The procedure typically takes about 5-10 minutes per ear.

Setting

This procedure is usually performed in hospitals, outpatient clinics, or specialized hearing centers.

Personnel

It is typically conducted by an audiologist or trained technician.

Risks and Complications

• No significant risks or complications are associated with this procedure.
• Rarely, minor temporary discomfort may be experienced due to the probe.

Benefits

• Early detection of hearing loss.
• Facilitates timely intervention and treatment.
• Supports proper speech and language development in children with hearing loss.

Recovery

• No recovery time is necessary.
• Normal activities can be resumed immediately.
• Follow-up appointments may be scheduled based on results.

Alternatives

• Auditory Brainstem Response (ABR) Testing: This is another type of hearing test that measures electrical activity in the brain in response to sound.
• Behavioral Audiometry: Involves observing a child's behavior in response to sounds of varying pitch, volume, or location.

Patient Experience

• The patient typically feels no discomfort during the procedure.
• No pain management is required.
• The test is silent and quick, minimizing any potential anxiety for young children.
