Abstract

Introduction: Knowledge of variable anatomy, narrow frontal sinus ostium and vital anatomical structures near outflow tract, is very important during preoperative planning for exposure of the frontal sinus recess during endoscopic sinus surgery. Preoperative knowledge of distance of nasofrontal beak and anterior skull base from columella is very helpful in avoiding intraoperative complication by deeper penetration into cranial cavity.

Aim: To analyse distance from columella to the anterior and posterior border of the Frontal sinus ostium in males and females by CT PNS.

Materials and methods: This retrospective observational study carried out in katihar medical college, Katihar during the period of 01 July 2021 to 31 December 2021 including 31 patients.

Result and conclusion: A distance approx 60.9 mm in men and 57.34 mm in women from the columella to frontal sinus ostium is safe during endoscopic sinus surgery.

额窦口与小柱距离的CT PNS分析及经验。

前言:了解额窦变型解剖、狭窄的额窦口和流出道附近的重要解剖结构，对于鼻内窥镜手术中额窦隐窝暴露的术前规划是非常重要的。术前了解鼻额喙及前颅底距小柱的距离，有助于避免术中较深的颅腔穿刺并发症的发生。目的:利用CT PNS分析男性与女性额窦口前后缘距小柱的距离。材料和方法:本回顾性观察性研究于2021年7月1日至2021年12月31日在卡蒂哈尔卡蒂哈尔医学院进行，包括31名患者。结果与结论:鼻内窥镜手术时，鼻小柱至额窦口的距离男性约60.9 mm，女性约57.34 mm是安全的。
