92579 Visual reinforcement audiometry (VRA)

Name of the Procedure:

Common Name(s): Visual Reinforcement Audiometry (VRA)

Summary

Visual Reinforcement Audiometry (VRA) is a hearing test commonly used to assess the auditory ability of young children, usually between the ages of 6 months to 2.5 years. This test uses sounds and visual stimuli to evaluate a child's hearing response.

Purpose

VRA is designed to detect hearing loss or evaluate hearing function in young children who are not able to communicate or cooperate fully during traditional hearing tests. The expected outcome is to determine the child's hearing threshold and ensure early intervention if hearing loss is detected.

Indications

• Observable delay in speech and language development
• Concerns raised by parents or caregivers about hearing abilities
• Follow-up on a failed auditory screening test
• Presence of risk factors for hearing loss (e.g., family history, neonatal complications)

Preparation

• No specific fasting or medication adjustments are required.
• Ensure the child is well-rested and comfortable.
• Prior diagnostic tests such as otoacoustic emissions (OAE) or tympanometry may be conducted.

Procedure Description

1. The child is seated on a caregiver's lap in a soundproof room.
2. Sounds of different pitches and volumes are played from speakers located at each side of the child.
3. Every time the child responds to a sound (e.g., by turning their head), a visual reward such as a moving toy or flashing light is presented as reinforcement.
4. The audiologist observes and records the child’s responses to determine the softest sounds they can hear at various frequencies.

Tools and Equipment: Sound speakers, visual reinforcers (e.g., toys, lights), and audiometry testing equipment. Anesthesia/Sedation: Not required.

Duration

The procedure typically takes between 30 to 45 minutes, depending on the child's cooperation and attentiveness.

Setting

Visual Reinforcement Audiometry is usually performed in an audiology clinic or a hospital's audiology department.

Personnel

The procedure involves:

• An audiologist who conducts the test and evaluates the results.
• Sometimes, an assistant or a nurse may help manage the child’s comfort.

Risks and Complications

There are minimal risks associated with VRA. Some potential complications include:

• The child becoming uncooperative or distressed during the test.
• Possible temporary hearing fatigue due to exposure to repeated sounds.

Benefits

• Early detection of hearing loss allows timely intervention and treatment.
• Accurate assessment of hearing ability contributes to better speech and language development, improving overall quality of life.
• Results are typically available immediately after the test.

Recovery

• No special post-procedure care is required.
• Children can resume normal activities immediately.
• Follow-up appointments may be scheduled for further evaluation or treatment if necessary.

Alternatives

• Behavioral Audiometry: Used for older children who can follow more complex instructions.
• Auditory Brainstem Response (ABR): A more detailed hearing test that may be recommended if VRA results are inconclusive.

Patient Experience

During the procedure, children may feel curiosity or mild discomfort due to unfamiliar sounds and visual stimuli. Comfort measures such as parental presence and breaks can help manage any distress. Pain management is not required as the procedure is non-invasive.
