Nasal endoscopy, also referred to as Rhinoscopy, is typically performed in an otolaryngologist's or ear, nose, and throat office where they have a direct, high-quality and magnified vision as they evaluate your sinus and nasal passages.

A nasal endoscope is an instrument that consists of a rigid, thin tube with fiber-optic cables. It connects to a video camera and light source where magnified images project onto a screen. The otolaryngologist then captures and records the endoscopic images to document for each patient.

During a nasal endoscopy procedure, the ear, nose and throat physician inserts the instrument into your nose and guides it through your sinus and nasal passages as they view the images of the area they're examining. The procedure helps with diagnosing and treating different health conditions. Sometimes, the physician may use small tools to perform certain tasks like gathering tiny tissue samples.
