随着鼻内窥镜手术的广泛开展，钩突切除术已成为内窥镜下筛窦开放与中鼻道上颌窦造口术的第一步。钩突切除后中鼻道拓宽，窦口复合体的清理均可在内窥镜下进行。钩突切除中鼻道开窗符合上颌窦粘膜纤毛的运动生理，有利于窦内分泌物的引流。我们在门诊开展功能性鼻内窥镜下钩突 With the extensive development of endoscopic sinus surgery, uncinatectomy has become the first step of endoscopic open ethmoid sinus and middle maxillary sinus. Hook excision in the widened after the middle nasal passages, sinus osseous complex can be cleared under endoscopy. Excision of the hook in the middle of the nasal passages in line with maxillary sinus mucociliary exercise physiology is conducive to the drainage of sinus secretions. We carried out a functional endoscopic uncinate process in the clinic
