An endoscopic sinus examination allows the doctor to see all the structures inside the nose and the sinuses.
Before inserting the endoscope, the passages inside the nose are opened up with a decongestant medicine and numbed with an anesthetic. The endoscope is guided up through a nostril and into the sinus opening, but it is not able to be inserted into the sinus itself.
The test is usually done by an ear, nose, and throat (ENT) specialist (also called an otolaryngologist or otorhinolaryngologist). It can be done in the doctor's office and takes 5 to 10 minutes.
An endoscopic sinus examination may be used if:
Findings of an endoscopic sinus examination may include the following.
