Bekesy audiometry; screening
CPT4 code
Name of the Procedure:
Bekesy Audiometry
- Common Names: Bekesy Audiometry
- Technical/Medical Terms: Automatic Audiometry, Continuous Tone Audiometry
Summary
Bekesy audiometry is a type of hearing test that uses an automatic tracking technique to measure a person's hearing sensitivity. It's designed to determine how well a person can hear sounds at various pitches and volumes.
Purpose
Bekesy audiometry helps diagnose hearing loss by identifying the softest sounds a person can hear at different frequencies. The primary goals are to:
- Assess the degree and type of hearing loss.
- Aid in creating an appropriate treatment or management plan for hearing issues.
Indications
This procedure is recommended for individuals who:
- Experience difficulty hearing or understanding speech.
- Have a history of exposure to loud noises.
- Have ear-related symptoms such as tinnitus (ringing in the ears) or vertigo.
- Require hearing assessment for occupational purposes.
Preparation
- Patients may be advised to avoid loud noises for 24 hours before the test.
- No special fasting or medication adjustments are typically required.
- Ensure ears are free from excessive ear wax, as it can affect the results.
Procedure Description
- The patient is seated in a soundproof booth and wears headphones.
- A continuous tone is played, and its intensity automatically adjusts based on the patient’s responses.
- Patients control a button to indicate when they can and cannot hear the tone.
The test tracks the thresholds of hearing across various frequencies.
Tools and Equipment:
- Audiometer with Bekesy audiometry capabilities
- Soundproof booth
- Headphones
Anesthesia or Sedation: Not required.
Duration
The procedure typically takes about 20-30 minutes.
Setting
Bekesy audiometry is performed in an audiology clinic or a specialized hospital department.
Personnel
- Audiologist or trained technician conducts the test.
- Otolaryngologist (Ear, Nose, and Throat specialist) may review and interpret results.
Risks and Complications
Bekesy audiometry is a low-risk procedure. Rarely, patients might experience:
- Mild discomfort from wearing headphones.
- Anxiety or confusion with the test process, particularly if inexperienced.
Benefits
- Accurate assessment of hearing ability.
- Identification of the type and degree of hearing loss.
- Information to guide treatment options, such as hearing aids or medical interventions.
Recovery
- Immediate recovery; patients can resume normal activities immediately after the test.
- Follow-up with the audiologist or ENT specialist to discuss results and potential treatment plans.
Alternatives
- Pure-Tone Audiometry: Measures hearing thresholds at specific frequencies without continuous tone adjustments.
- Speech Audiometry: Assesses the ability to understand and repeat spoken words.
Tympanometry: Evaluates the function of the middle ear and eardrum.
Pros and Cons Compared to Bekesy Audiometry:
- Pure-Tone Audiometry: Easier for patients to understand, but less detailed.
- Speech Audiometry: Useful for real-world hearing issues but does not measure specific frequency thresholds.
- Tympanometry: Focuses on middle ear function, not direct hearing sensitivity.
Patient Experience
During the procedure, the patient may feel a bit of anticipation or concentration but generally will not experience pain. The environment is controlled to be quiet and comfortable. Post-procedure, there should be no lingering discomfort, and results are typically shared in a follow-up appointment.
