筛泡基板前上端在鼻内镜额窦手术中的定位作用

目的寻找适合鼻内镜手术下开放额窦的解剖学标志,以降低手术并发症的发生率。方法对30例(60侧)慢性鼻窦炎病人行鼻窦CT扫描,根据CT扫描中筛泡基板前上端向上附着的部位与纸样板/筛顶的关系,术中以筛泡基板前上端为标志,寻找额窦开口,进行鼻内镜额窦手术。并与同期40例(75侧)依据前筛顶额突为标志进行鼻内镜额窦开放术的手术并发症的发生率进行比较。结果30例(60侧)病人在以筛泡基板前上端为解剖标志进行鼻内镜额窦开放术中,手术并发症的发生率为3.3%(1/30),与同期40例(75侧)病人依照颅底额突作解剖标志进行鼻内镜额窦开放术的手术并发症的发生率20%(8/40)进行比较有统计学意义(P<0.05)。结论在鼻内镜额窦手术中以筛泡基板前上端为解剖标志,能有效地帮助寻找额窦开口,降低手术并发症的发生率。

Anterosuperior basal lamella of bulla as an identific landmark in endoscopic frontal sinus surgery

Objective To evaluate the effect of the anterosuperior basal lamella of bulla as an identific landmark of frontal sinus ostium in endoscopic frontal sinus surgery.Methods Computed tomographic(CT) imaging of the sinus was obtained in coronal and axial views.Thirty patients'(60 sides) frontal ostia were identified according to the anterosuperior basal lamella of bulla in endoscopic frontal sinus surgery.Meanwhile,40 patients(75 sides) were operated according to the roof of anterior skull base.Surgical complications of the two groups were compared with each other.Results The surgical complication rate was(3.3%)(1/30) in 30 patients operated according to the anterosuperior basal lamella of bulla,while,20%(8/40)in 40 patients(75 sides) operated according to the roof of anterior skull base;the difference was statistically significant(P<(0.05)).Conclusion The anterosuperior basal lamella of bulla is a useful anatomic landmark of guidance for the endoscopic frontal sinus surgery.
