A nasoendoscopy is a medical procedure that allows a doctor to look into your nasal passages, throat, and voice box or larynx to diagnose potential issues. An endoscope is used for this procedure -- a thin, flexible tube that can be passed through the nose and into the nasopharynx, through the oropharynx, and beyond to the voice box. The endoscope is equipped with a light and video camera that allows the operator to see where they are going. The doctor can also use the endoscope to take a tissue biopsy.
There are many reasons your doctor might order a nasoendoscopy, from the reasonably mild ENT issue to considerably more severe problems such as a suspicion of cancer. Continued nosebleeds, nasal polyps, sinusitis, issues with swallowing or speaking, and sleep apnea could also call for a nasoendoscopy.
