International Session 27　　Sinus Surgery

Frontal sinus surgery remains technically demanding due to complex anatomy and limited access to the frontal recess.Endoscopic management requires precise anatomical orientation and individualized surgical planning.This lecture reviews advanced endoscopic approaches to frontal sinus disease, focusing on key anatomical landmarks, frontal sinus drainage pathways, and the role of preoperative imaging.Technical aspects of Draf II and Draf III procedures are discussed, including indications, extent of drilling, and strategies to optimize frontal sinus patency.Particular emphasis is placed on mucosal preservation, management of frontal cells, and prevention of postoperative restenosis.Challenges in revision surgery and methods to minimize complications are also addressed.This presentation aims to provide practical, technique-oriented insights for improving surgical outcomes in complex frontal sinus disease.
