鼻内镜下经硬腭鼻底鼻咽肿瘤切除术

目的探讨鼻内镜在鼻底鼻咽肿瘤切除手术中的应用价值。方法2001年1月~2005年1月共进行手术12例,其中鼻底肿瘤5例,鼻咽肿瘤7例。全部患者均在气管插管全麻,鼻内镜下经硬腭径路手术,其中3例鼻咽肿瘤术前采用血管造影并进行肿瘤供血动脉栓塞,术中根据需要采用控制性低血压技术。结果2例恶性肿瘤术中冷冻确诊后更改术式,其余10例术后硬腭黏骨膜瓣愈合良好,发音、吞咽、呼吸、咀嚼等功能正常,随访1年以上无复发。结论鼻内镜下经硬腭切除鼻底鼻咽肿瘤较传统硬腭径路手术有明显优势。

Treatment of Tumor in Nasopharynx and the Base of Nasal Cavity by Hard Palate Approach Through Endoscopic Surgery

Objective To evaluate the practical value tumor from nasopharynxl and the base of nasal cavity . Methods 12 patients , among these 5 cases suffered from the tumor of the base of nasal cavity and 7 from nasopharynx , were treated from January 2001 to January 2005 . After general anesthesia the tumors were incised by hard palate approach , and the preoperative selective intraarterial embolization were used in three nasopharyngeal tumors, and The controlled hypotension were used during surgery ifnecessary.
