额钻辅助定位在经鼻内镜额窦修正手术中的评价

目的:评价额钻辅助定位在经鼻内镜额窦修正手术中的应用及意义。方法:回顾性分析11例(18侧)因复发性额窦炎行经鼻内镜额窦修正手术患者的资料,11例患者术中均不能辨认额窦开口,以额钻辅助定位额窦开口,术后随访观察评估疗效。结果:11例(18侧)额窦炎患者均在额钻辅助定位的帮助下,成功开放额窦,除1例(1侧)术中损伤筛前动脉引起出血外,余10例(17侧)未发生严重并发症。术后随访7～35个月,术前症状均消失,经鼻内镜检查额窦口开放良好。结论:在经鼻内镜额窦修正手术中以额钻辅助定位额窦开口是一种简单、易行、安全、可靠的方法。

Application of frontal drill in revision endoscopic frontal sinus surgery

Objective:To discuss the application of frontal drill in revision endoscopic frontal sinus surgery.Method:The clinical data of 11 adult patients (18 sides) suffering from chronic recurrent frontal sinusitis were analyzed retrospectively. The patients received revision endoscopic frontal sinus surgery with frontal drill because of difficulty in confirming ostia under endoscope. Postoperatively all cases were followed up to evaluate the efficacy.Result:The ostia of frontal sinus were successfully opened with this method in all cases, and no serious complications occurred except hemorrhage due to injury of anterior ethmoidal artery in 1 case. After 7 to 35 months follow-up postoperatively, the symptoms vanished in all cases and none recurred. The endoscopic examinations showed well-opening of frontal sinus ostia.Conclusion:Localization of frontal ostium with frontal drill is a simple, convenient, safe and effective accessorial method for revision endoscopic frontal sinus surgery.
