Will nasal endoscopy be painful for my daughter?

Maybe: For routine trans-oral endoscopy, sedation is routinely offered. Transnasal endoscopy is an alternative where the viewing tube is tiny enough to pass through the nose. In the latter case, sedation may be deferred. Keep in mind the test lasts only 3-5 minutes. Talk with her doctor about what sedation options she can have at the center where her test will be performed.
