Abstract
This chapter provides a comprehensive overview of advancements and methodologies in extended sinus surgeries. It elucidates surgical techniques, key anatomical landmarks, indications, and postoperative care necessary for effectively managing refractory chronic rhinosinusitis and other complex sinonasal conditions. A detailed examination of various approaches, such as Endoscopic Maxillary Mega-Antrostomy (EMMA), Modified Medial Maxillectomy, Denker’s approach, and Draf IIb and III procedures, is discussed, highlighting the anatomical considerations, surgical steps, and postoperative protocols to optimize patient outcomes and minimize complications. Extended sinus surgeries offer enhanced access to difficult-to-reach areas, allow better management of extensive disease processes, and provide improved pathways for drainage and disease resolution, utilizing advanced endoscopic techniques that preserve critical structures and promote faster recovery compared to traditional methods. The evolution of endoscopic sinus surgery has significantly transformed the management of sinus diseases, making extended sinus surgeries crucial for patients who have failed conventional treatments and presenting a viable option for addressing severe and complex pathologies. By understanding the detailed surgical techniques and postoperative care outlined in this chapter, surgeons can achieve better outcomes and improve the quality of life for their patients.
