Home > Wellness > Health Library > Sleep Apnea: Fiber-Optic Pharyngoscopy
Fiber-optic pharyngoscopy is a procedure that allows your doctor to
look into the upper part of your
respiratory system. He or she may use it to help
decide how to treat your obstructive
sleep apnea (OSA).
You remain awake during the procedure. Your doctor gives you medicine
(anesthesia) to numb your throat and then places a
thin, flexible tube (endoscope) inside your nostril and gently guides the tube
into your throat. A camera at the end of the tube sends pictures to a video
This process is sometimes done while you are using
continuous positive airway pressure (CPAP) to find the
areas in your airway that collapse during sleep.
