摘要
目的 :探讨计算机智能导航系统在鼻科和耳科手术中应用的有关问题。方法 :霉菌性蝶窦炎 1例 ,巨大额筛窦囊肿 1例 ,先天性外耳道闭锁 3例 ,均在影像导航系统下进行鼻内窥镜手术和显微镜手术。结果 :术前准备时间 16～ 30min ,平均 2 7min。配准系数在 1.3～ 2 .0之间 ,平均 1.92。影像与实体指示之间误差小于 1mm的是中耳、颅底、乳突 ,误差小于 1.3mm的区域是鼻腔鼻窦。 5例手术均顺利 ,无术中、术后并发症。手术时间与传统的鼻内窥镜手术和耳显微手术相比差异无显著性意义。结论 :导航手术可以帮助医师在手术中确认鼻、耳及与之相连接的高危解剖区域的标志 ,既提高了手术的精确性 ,又提高了手术的安全性 ,是未来耳鼻咽喉微创外科的方向之一。
Objective:To explore related issues of image guidance system in oto rhino surgery application through 5 cases of ear and nose diseases.Method:All operations were carried out with endoscope or microscope under the guidance of computer aided landmark system. Five patients include one fungus sphenoid sinusitis, one enormous cyst of ethmoid frontal sinus and three congenital external meatus block.Result:Preoperative preparation time is 16～30 minutes, with an average of 27 minutes. The quotient of calibration is 1.3 ～ 2.0 , with an average of 1.92 . Precise error between image and entity are less than 1 mm in base of skull, mastoid; less than 1.3 mm in nasal cavity and sinuses. Operations were successfully finished without complication intraoperatively or postoperatively.The time spent on surgery with image guidance system is as similar as that of conventional way.Conclusion:Image guidance system is useful for doctors to precisely recognize the mark of high dangerous area in nose, ear and surroundings, which is helpful to improve both the accusation and safety. It is one of the developing directions of microsurgery on otolaryngology field in the future.
