一种自研带舌根拉钩开口器在舌根深部手术中的应用

Clinical application of a self-developed mouth opener with a tongue base retractor in the operation of deep part of tongue base

目的:测试一种自研带舌根拉钩开口器在舌根深部手术中的应用效果。方法:对8例经口入路行舌根深部手术的患者采用自研带舌根拉钩开口器暴露舌根术野,观察该开口器的操作难度、术野暴露效果、咽部黏膜撕裂情况以及术后舌麻痹风险。结果:自研开口器在术中可利用自带舌根拉钩暴露舌根深部术野,并在角度内镜引导下进行手术操作,8例患者手术全程术野暴露良好,未出现咽部黏膜撕裂情况以及术后舌麻痹。结论:在舌根深部手术应用自研开口器暴露术野,具有操作简单、暴露效果良好及并发症少等优点,但部分操作仍需刚性弯曲手术器械配合。

Objective: To test the application effect of a self-developed mouth opener with a tongue base retractor in the operation of the deep part of tongue base. Methods: The tongue base surgical field was exposed by using a self-developed mouth opener with a tongue base retractor in 8 patients who underwent deep tongue base operation via oral approach, the difficulty of operation, the effect of exposure of operation field, the tear of mucous membrane of the pharynx arch and the risk of tongue paralysis were observed. Results: The self-made mouth opener can expose the deep operative field of the tongue root by using the self-provided tongue root retractor during the operation, and the operation is conducted under the guidance of angle endoscope. The operative field of 8 patients was well exposed during the whole operation, there was no pharyngeal mucosa tearing and postoperative tongue paralysis. Conclusion: The self-made mouth opener has the advantages of simple operation, good exposure effect and less complications, but it needs rigid bending instruments in some operations.
