DNE full form in medical term is Diagnostic Nasal Endoscopy. An evaluation of the nasal cavity can be achieved using diagnostic nasal endoscopy, which involves inserting a thin, lighted fiber optic device into the nasal cavity and viewing the area there.
A standard flashlight isn’t suited for inspecting the inside of the nose because it’s a big, open space. A “keyhole” view of the nose’s front is possible during a normal inspection because just the area that surrounds the nose is lit.
The remaining of the nasal passage is left in the dark. The endoscope’s bright light and powerful magnification make it possible to examine the nasal passages, sinus entrance, nasal back, and Eustachian tube in all their anatomical glory
Initial anesthesia and decongesting of the nose make this a rather comfortable treatment. A local anesthetic and nasal decongestant combination is used to ease the transit of the endoscope as well as to numb the nose for a short time. Patients with abnormally narrow nasal cavities or bulging nasal linings may feel some discomfort during the surgery, but this is rare.
Due to the short duration of the surgery, the risk of consequences is minimal. Rarely, after the inspection, you can experience some bleeding from the nose. Typically, bleeding is little and ceases on its own.
