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 the application of computer intelligent navigation system in nasal and otological surgery. Methods: One case of fungal sphenoid sinusitis, one case of giant sinuses ethmoid cysts, and 3 cases of congenital external auditory canal atresia were performed endoscopic sinus surgery and microscopic surgery under the imaging navigation system. Results: Preoperative preparation time 16 ~ 30min, an average of 27min. The registration coefficient is between 1.3 and 2.0, averaging 1.92. The error between the image and the entity indication is less than 1mm in the middle ear, skull base, mastoid, the error is less than 1.3mm area is nasal sinus. 5 cases of surgery were smooth, no intraoperative and postoperative complications. There was no significant difference between the operation time and traditional endoscopic sinus surgery and ear microsurgery. Conclusion: Navigational surgery can help doctors identify the signs of nose, ear and the connected high-risk anatomical area during operation, which not only improves the accuracy of the operation but also improves the safety of operation. It is the future minimally invasive surgical treatment of otolaryngology One of the directions.
