慢性鼻窦炎的治疗主要是功能性内窥镜手术,主要解决窦口鼻道复合体,改善鼻腔、鼻窦的引流和通气功能,从而达到治愈的目的。筛窦因其解剖结构的特殊性,它的炎症可扩散到其他鼻窦,导致其他鼻窦炎的发生。因此,作者针对它的解剖特点和临床作用,对早期鼻窦炎患者均做筛窦开放术。1 The treatment of chronic sinusitis is mainly functional endoscopic surgery, mainly to solve the ostiomeatal complex, to improve nasal and sinus drainage and ventilation functions, so as to achieve the purpose of cure. Ethmoid sinus due to its special anatomy, its inflammation can spread to other sinus, leading to the occurrence of other sinusitis. Therefore, the author aimed at its anatomical features and clinical role in patients with early sinusitis are done ethmoid open surgery. 1
