Nasal endoscopy is a minimally invasive, diagnostic medical procedure. It is used to examine the interior surfaces of the nasal cavity and nasopharynx not possible by standard examination. The nasal endoscope is a rigid or flexible tube that emits light and acts as a camera to project a magnified image on a screen. These endoscopic images can be captured and recorded for documentation for each patient. The superior visualization capabilities enabled by nasal endoscopy, have made this procedure standard in the diagnosis and management of nasal and sinus conditions.
You might need a nasal endoscopy if your healthcare provider needs more information about problems such as:
Nasal and sinus infection (rhinosinusitis)
Loss of ability to smell
Cerebrospinal fluid leak
The endoscopy can show specific details, such as the site of bleeding and swelling of nasal tissue. It can also be used to identify a growth that might be cancer. Very small pathology may be visualized on nasal endoscopy and missed on CT and MRI scans.
