ABSTRACT
Anatomy and surgery teaching has always been a difficulty in clinical medical education. In particular, the anatomy and surgery teaching under the endoscope is more difficult to learn and under-stand because of the visual differences with the direct vision. If the students misunderstand, it may lead to the severe surgical complications. We applied the image-guidance technology in the teaching of rhinology endoscope surgery, which can help teachers to teach the sinonasal anatomical structure and give an accurate explanation of surgical procedures. According to the questionnaire survey, 96.23% (51/53) of the students thought the method was effective and clear, and 98.11% (52/53) of them thought the method was better than the traditional teaching method of nasal endoscope. By this technology, the students can acquire a deeper understanding of the anatomy and surgery procedure. It especially fits the surgery teaching of the sinonasal occupying lesion.
