Modification of Septal Window to Improve Angled Endoscopic View for Beyond Maxillary Sinus

Supplemental Digital Content is available in the text Abstract Many endoscopic surgeons have showed various techniques on septal window using endoscopic tools. However, each technique has its own merits and faults. In this study, the authors introduce simple and time saving endoscopic window technique by avoiding intranasal suture resulting from simple incision line. The procedure to make septal window is to improve an angled endoscopic view for beyond lateral wall of maxillary sinus with septum preservation. To date, this approach has shown no major or concerning complications and has also showed favorable disease control outcomes while maintaining nasal airway patency and functionality through our experience.
