During a laryngoscopy, a doctor uses a thin, lighted tube (a laryngoscope) to examine the larynx (voice box).
Two types of laryngoscopy may be performed:
- Indirect laryngoscopy - A small, long-handled mirror is inserted into the throat so parts of the larynx can be examined.
- Direct laryngoscopy - An instrument called a laryngoscope is inserted through the nose or mouth. The scope is a narrow, lighted tube, which provides a better view of the area than the indirect laryngoscopy.
A biopsy, removal of a sample of tissue to be evaluated under a microscope by a pathologist, may also be performed.
If cancerous cells are found, imaging procedures may be used to determine the extent, or stage of the cancer.
