1. Learn about endoscopic nasal examination and biopsy
Endoscopic examination of the nasal cavity is an examination method that uses a magnifyingoscope to observe every nook and cranny inside the nasal cavity such as: septum, nasal cavity, nasal coil, the openings of the sinuses pouring into the nose, the portal posterior nose and nasopharynx.
The advantage of nasal cavity endoscopy is that it uses an endoscope with an appropriate length and diameter for age. In addition, using a video recorder system connected to a microprocessor to enlarge the image on the TV screen, record video of the screening process. Thanks to that, the observation, assessment and/or biopsy of the lesion at the right location will give more accurate results.
Diagnostic nasal endoscopy is a procedure that inserts a bronchoscope through the nostrils into the nasal cavity. Usually, the endoscopist often sprays anesthetic and mucosal constrictors a few minutes before the examination to open the nasal cavity and temporarily lose pain. This helps the bronchoscope move easily, accurately identify the disease and the patient does not feel pain during the examination.
Nasal cavity biopsy is an endoscopic nasal biopsy procedure, using endoscopic images to find the suspicious area, then taking a piece of pathological tissue in the nasal cavity for histopathological examination. Indicated in cases of suspected malignancy based on endoscopic images that need to determine histopathology.
