Frequently Asked Questions about Videostroboscopy

What happens during the evaluation?

Step 1:
You will first be asked to complete a questionnaire regarding the onset of your voice problem, your medical history and current medications, current voice demands, and any specific symptoms related to your voice problem. 

Step 2:
A speech pathologist will guide you in performing simple vocal tasks using a microphone.  Computer analysis of your vocal quality will then be performed.

Step 3:
The physician may spray a topical anesthetic in your throat for your comfort during the procedure. (Note: Please inform the physician if you have had any reactions to anesthesia in the past.)

Step 4:
The physician will insert a small endoscope through your mouth towards the back of your tongue.  The endoscope provides a telescopic video recording of your larynx.  The speech pathologist will then ask you to peform various voice tasks in order to observe the movement of your vocal cords and the condition of your larynx.

How long will it take?

The entire evaluation may take approximately thirty minutes to one hour; however, the total time that the endoscope is in your mouth is only approximately two minutes.

Immediately following the evaluation, the physician and speech pathologist will review your results and provide recommendations which may include one or all of the following:  referrals, medication, voice therapy, and/ or surgery.
