Larynx Cancer Investigations
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 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.
