目的比较鼻内镜下上颌窦自然口和前壁径路切除上颌窦囊肿和息肉手术的优缺点。方法将上颌窦囊肿和息肉患者共48例分为两组,自然口径路组24例,前壁径路组24例,自然口径路组鼻内镜下切除钩突,扩大上颌窦自然口,经扩大的自然口切除上颌窦内囊肿息肉;前壁组鼻内镜下上颌窦穿刺套针经前壁穿刺两个窗口,鼻内镜观察下切除上颌窦内囊肿息肉。结果术后随访6月至1年,两组均无明显并发症发生。自然口径路组复发率12.5%,前壁径路组复发率0.0%,差异有统计学意义(P<0.05)。结论鼻内镜下前壁径路暴露清楚,可彻底清除病灶,不易复发,且不破坏上颌窦自然口的功能,具有微创的特点。 Objective To compare the advantages and disadvantages of maxillary sinus cyst and polyp surgery under nasal endoscopic natural port and anterior wall approach. Methods A total of 48 patients with maxillary sinus cyst and polyp were divided into two groups: 24 cases in the natural caliber group and 24 cases in the anterior wall group; the uncinate process was removed under the endoscope by the natural caliper group and the natural port of the maxillary sinus was enlarged; Of the natural mouth resection of the maxillary sinus cyst polyps; anterior wall group of maxillary sinus puncture through the anterior wall of the needle through the anterior wall puncture two windows, endoscopic sinus resection of maxillary sinus cyst polyps. Results The patients were followed up for 6 months to 1 year, no significant complications occurred in both groups. The recurrence rate of natural calluses was 12.5% ​​and that of anterior parietal approach was 0.0%, the difference was statistically significant (P <0.05). Conclusions The endoscopic approach of anterior wall of nasal endoscope is clearly exposed, which can completely remove the lesion and is not easy to recur, and does not destroy the function of natural maxillary sinus mouth.
