Revision Sinus Surgery for Recalcitrant Chronic Frontal Rhinosinusitis: Draf IIA/Draf IIB
摘要
Frontal sinus surgery has evolved significantly from its origins, which were dominated by extirpative procedures such as radical frontal sinus ablation and trephine-based obliteration [1]. Advances in our knowledge and technology have fueled the evolution of techniques. Contemporary frontal sinus surgery aims to restore physiological drainage of the frontal outflow tract through endoscopic endonasal approaches that emphasize mucosal preservation and wide osteotomies. The goals of frontal sinus surgery are threefold: (1) maintain ostial patency, (2) optimize the delivery of topical medications to the sinonasal mucosa, and (3) prevent obstruction of the drainage pathway, which may lead to mucocele formation.
