An endoscopic sinus exam 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)

otolaryngologist or otorhinolaryngologist). It can be
done in the doctor's office and takes 5 to 10 minutes.
