Laryngeal papillomatosis other diagnostic studies

Two routine tests for laryngeal papillomatosis are indirect and direct laryngoscopy. In an indirect laryngoscopy, an otolaryngologist—a doctor who specializes in diseases of the ear, nose, throat, head, and neck—or speech-language pathologist will typically insert a flexible fiber optic telescope, called an endoscope, into a patient’s nose or mouth and then view the larynx on a monitor. Some medical professionals use a video camera attached to a flexible tube to examine the larynx. An older, less common method is for the otolaryngologist to place a small mirror in the back of the throat and angle the mirror down toward the larynx to inspect it for tumors.

A direct laryngoscopy is conducted in the operating room with the use of general anesthesia. This method allows the otolaryngologist to view the vocal folds and other parts of the larynx under high magnification. This procedure is usually used to minimize discomfort, especially with children, or to enable the doctor to collect tissue samples from the larynx or other parts of the throat to examine them for abnormalities.

The most accurate way to diagnose laryngeal papillomatosis is for a biopsy to be conducted and for the lesion to be tested for HPV. This procedure takes place in an operating room with the patient under general anesthesia. This is sometimes the best option for small children.
