Dear Dr. Dankle:
I came across your response to a person on the Internet regarding a deviated septum and wondered if you might be able to answer some questions I had about a nasal endoscopy. I have been "snorting" for years, and my doctor says I have a deviated septum. However, he wants to perform an endoscopy to see "what's going on up there".
I live outside of Toronto, and am scheduled to undergo a nasal endoscopy in 2 days. For some reason, this procedure scares me. Is there any way that an endoscope can damage the cartilage or internal structure of the nose during an examination (I've heard rumors about this)? Are there any possible complications from an endoscopic exam that you know of? How large in diameter is an endoscope, and how long does this procedure usually take?
Any information you are willing to provide me with would be much appreicated.
Thank you for your time,
Answer -----------
Nasal endoscopy is a valuable and now, routine diagnostic measure used for examining the internal structures of the nose. It allows for easy visualization of the complex anatomy of the nasal passageway which is difficult to appreciate by standard anterior rhinoscopy using a nasal speculum. It can be particularly helpful for examination of the nose in an individual with a deviated septum because a reliable examination in a patient with a deviated septum can be difficult with a nasal speculum alone.
Typically, nasal endoscopy, is now done as part of a routine nasal examination in a patient with a nasal or sinus complaint, in whom a detailed intranasal examination is necessary in order to formulate a diagnosis and to plan appropriate intervention. It is an office procedure and can be done with little or no discomfort. Generally a topical nasal decongestant spray such as Afrin is used to shrink the membranes of the nose. Then a topical anesthetic spray is used such as Xylocaine to numb the membranes of the nose. The examination is sometimes done with a camera attached to the endoscope for photodocumentation. The endoscope diameter is roughly 3 millimeters. There is very little risk associated with the procedure and the chance for significant injury to cartilage or other nasal structures is remote.
