目的:探讨鼻咽纤维血管瘤术前放疗对减少术中出血和术后复发的作用。方法:33例患者中,单纯手术者21例,12例手术前两周行~(60)Co放射5～7 d,放射量10～20 Gy。结果:21例单纯手术者,术中出血250～3600 mL,平均1 100 mL,术后复发4例。而12例放疗加手术者,术中出血200～800 mL,平均450 mL,术后无复发。术中出血较单纯手术者显著减少(t=1.97,P<0.01)。结论:放疗后切除鼻咽纤维瘤,有利于减少术中出血和术后复发。
Objective: To investigate the effect of preoperative radiotherapy of nasopharyngeal fibrosimplant on the reduction of intraoperative bleeding and postoperative recurrence. Methods: Among the 33 patients, 21 cases were operated on alone and 12 cases were treated with ~ (60) Co for 5 ~ 7 days and the radiation dose was 10 ~ 20 Gy two weeks before surgery. Results: 21 cases of simple surgery, intraoperative bleeding 250 ~ 3600 mL, an average of 1 100 mL, 4 cases of postoperative recurrence. The 12 cases of radiotherapy plus surgery, intraoperative bleeding 200 ~ 800 mL, an average of 450 mL, no recurrence after surgery. Intraoperative bleeding was significantly reduced compared with surgery alone (t = 1.97, P <0.01). Conclusion: Radiotherapy after nasopharyngeal fibroids resection, is conducive to reducing intraoperative bleeding and recurrence.
