中文摘要：

目的：评价额窦光导探子辅助定位在鼻内镜额窦手术中的应用及意义。方法：回顾性分析58例（86侧）经鼻内镜额窦手术患者的资料,术中以额窦光导探子辅助定位额窦开口,术后随访观察评估疗效。结果：58例（86侧）额窦炎患者均在额窦光导探子辅助定位的帮助下,术中成功开放额窦窦口,无颅内及眶内并发症发生。术后随访6-18个月,无额窦炎复发。51例患者术前症状完全改善,7例术前症状明显改善,经鼻内镜检查额窦口开放良好。结论：在鼻内镜额窦手术中以额窦光导探子辅助定位额窦开口是一种简单、易行、安全、可靠的方法,对于保证手术的成功、增强术者的信心、预防并发症的发生有重要的意义。

英文摘要：

Objective To discuss the application of frontal sinus optical probe in endoscopic frontal sinus sur-gery. Method.. The clinical data of 58 adult patients （86 sides） suffering from chronic frontal sinusitis were ana-lyzed retrospectively. The patients received endoscopic frontal sinus surgery with frontal sinus optical probe be-cause of difficulty in confirming ostia under endoscope. All cases were followed up post operation to evaluate theefricacy. Result：The ostia of frontal sinus were successfully opened with this method in all cases, and no seriousintracranial or orbital complication occurred. After 6 to 18 months follow-up postoperatively, the symptoms van-ished in 51 cases and improved in 7 cases and none of all recurred. The endoscopic examinations showed well open-ing of frontal sinus ostia. Conclusion： Localization of frontal ostium with frontal sinus optical probe is a simple,convenient, safe and effective accessorial method for revision endoscopic frontal sinus surgery.
