Laryngoscopy is an examination that lets doctor looks at the back of patient’s larynx, and vocal cords with a laryngoscope. There are two types of laryngoscopy, indirect and direct laryngoscopy. Indirect laryngoscopy is performed in the office using a small hand mirror held at the back of the throat. Doctor illuminates a light in patient’s mouth and wears a mirror on his or her head in order to reflect light to the larynx. Direct laryngoscopy uses a tube called a laryngoscope. The instrument is placed in the larynx. The tube may be flexible or rigid. This procedure allows the doctor to see deeper in the throat and to remove a foreign bodies or sample tissue for a biopsy. It is performed in a hospital or medical center under general anesthesia.[23]
