目的：探讨鼻咽原发癌救援性外科治疗的新进路。材料与方法：６例鼻咽癌放疗后鼻咽复发患者，采用上颌骨－鼻内翻进路切除鼻咽复发癌。结果：６例鼻咽癌放疗后隐窝或侧壁的复发癌，经上颌骨－鼻内翻后，能够充分显露鼻咽及相邻的部分鼻咽旁组织，进行根治性手术切除，手术切缘病理均为阴性。术后伤口按期愈合，且口腔功能不受影响。术后随访１年未见复发。结论：上颌骨－鼻内翻进路能够充分暴露鼻咽及鼻咽旁间隙，将鼻咽及扩展到鼻咽旁和鼻腔的癌瘤根治性切除；该进路也可用于鼻咽其它肿瘤或颅底肿瘤的手术切除。
Objective: To explore a new approach to rescue surgical treatment of primary nasopharyngeal carcinoma. Materials and Methods: Nasopharyngeal recurrence was performed in 6 patients with nasopharyngeal carcinoma after radiotherapy. The maxillofacial-nasal approach was used to excise nasopharyngeal carcinoma. Results: 6 cases of nasopharyngeal carcinoma after radiotherapy of recurrent cancer of the crypt or sidewall, the maxillary - nasal inverted, can fully reveal the nasopharynx and adjacent parts of the nasopharyngeal tissue for radical surgical resection, surgical resection Pathology are negative. Postoperative wound healing on schedule, and oral function is not affected. No follow-up 1 year follow-up. CONCLUSIONS: Maxillary-nasal pronation approach can fully expose the nasopharynx and parapharyngeal space, and excise the nasopharynx and the cancer extending to the nasopharynx and nasal cavity. The approach can also be used for other tumors of the nasopharynx or Surgical resection of skull base tumor.
