The use of video in ENT endoscopy: its value in teaching

Videography is the most practical and effective method of documenting and teaching ENT endoscopy. Videography allows: (1) documentation of anatomy, physiology and pathology of deep structures of the ear, nose and throat; (2) teaching of delicate surgical procedures such as functional endoscopic sinus surgery (FESS), laryngeal surgery, and other endoscopic procedures; (3) instantaneous production of high quality hard copies of video images for teaching and patient records; (4) instant replay and repeated viewing by a slow motion or frame-by-frame analysis; (5) simultaneous viewing by a small or large audience; and (6) image digitalization for storage in the computer for later analysis. The author describes the value of videography in ENT endoscopy, namely video-otoscopy, video rhinoscopy and videolaryngoscopy. The use of video in endoscopy will continue to play a vital role in Continuing Medical Education (CME).
