鼻癌原发灶切除术进路在文献中报道很多。但由于鼻咽腔解剖结构的限制,现有的手术进路均不能明视鼻咽腔的全貌,影响了术者的视野和操作,因而有些学者认为彻底清除鼻咽癌原发灶是不可能的。我们认为只要有显露良好和安全简便的手术进路有可能彻底清除肿瘤。为此,我们设计了腭正中切开显露鼻咽腔的手术方案,施行鼻咽癌原发灶切除术4例取得较为满意的效果。手术方法: 1.气管切开全身麻醉:常规气管切开, The primary tumor resection approach for nasal cancer has been reported in the literature. However, due to the limitation of the anatomical structure of the nasopharyngeal cavity, the existing surgical approach can not fully view the entire nasopharyngeal cavity, affecting the operator’s vision and operation, and some scholars believe that it is impossible to completely remove the primary tumor of nasopharyngeal carcinoma. of. We believe that as long as there is a well-shown, safe, and simple surgical approach, it is possible to completely remove the tumor. To this end, we designed a surgical plan to open the exposed nasopharyngeal cavity in the middle of the palate. Four cases of nasopharyngeal primary tumor resection were performed satisfactorily. Surgical methods: 1. Tracheotomy general anesthesia: conventional tracheotomy,
