目的:探讨DrafⅡb型手术治疗额窦内翻性乳头状瘤(NIP)的疗效。方法:回归性分析15例行DrafⅡb型手术治疗的额窦NIP患者的临床资料,采用生存分析法计算临床成功率和手术成功率。结果:15例患者中肿瘤复发1例(6.67%),额窦口狭窄1例(6.67%),额窦口闭锁4例(26.67%),并发额窦黏液囊肿1例(6.67%)。DrafⅡb型手术治疗额窦NIP的3年临床成功率为93.3%,3年手术成功率为65.0%。结论:对于累及瞳孔中线以内范围的额窦NIP均可考虑采用DrafⅡb术式,该术式的常见并发症为术后额窦口狭窄或闭锁,建议术后1年内密切随访。降低并发症的措施有待进一步探究。
Objective: To investigate the curative effect of DrafⅡb operation on frontal sinus inverted papilloma (NIP). Methods: The clinical data of 15 patients with frontal sinus NIP treated with DrafⅡb operation were retrospectively analyzed. Survival analysis was used to calculate the clinical success rate and surgical success rate. Results: One patient (6.67%) had a tumor recurrence in 1 patient, 1 patient (6.67%) had a frontal sinus ostium stenosis, 4 patients (26.67%) had frontal sinus ostium atresia, and 1 patient (6.67%) had a frontal mucosal cyst. The 3-year clinical success rate of drafⅡb-type surgery for frontal sinus NIP was 93.3%, and the success rate of 3-year surgery was 65.0%. CONCLUSIONS: DrafⅡb procedure is considered for the frontal sinus NIP involving the mid-pupil midline. The common complication of this procedure is postoperative frontal sinus stenosis or occlusion, which is recommended for close follow-up within 1 year after surgery. To reduce the complications of measures to be further explored.
