###5: What the procedure examines
###6: The scope provides a direct view of areas that may be difficult to assess from the outside, including the throat, voice box, and upper airway. The exact areas examined depend on the reason for the procedure.
###7: Why it is performed
###8: Endoscopy may be recommended for persistent throat discomfort, trouble swallowing, hoarseness, coughing, breathing symptoms, neck swelling, or an abnormal area found during a physical examination.
###9: What to expect
###10: The clinician usually applies numbing medication to the nose or throat and passes a flexible scope through the nose or mouth. You may be asked to breathe, swallow, or speak during the examination, and any tissue samples are sent separately for pathology review.
###11: Understanding the results
###12: The endoscopy report describes what was seen during the procedure. If a biopsy was performed, pathology results are provided in a separate report and are needed to determine what caused an abnormal finding.
