目的探讨内窥镜鼻窦手术中不同上颌窦自然开口处理方法与术后预后的关系。方法对慢性鼻窦炎、鼻息肉患者98例随机分为研究组52例,采用根据窦口的形态与上颌窦本身的病变情况,处理窦口周围组织而不扩大窦口,对照组46例,采用扩大上颌窦口,观察两组窦口开放率和闭合率。结果随访1年,发现研究组与对照组的窦口开放率分别为96.15%:71.74%和闭合率分别为3.85%:28.26%,差异有统计学意义(P<0.01)。结论扩大上颌窦开口发生狭窄和闭锁的比率,高于保持窦口黏膜完整,内窥镜鼻窦手术保持自然口周围黏膜的完整性,使术腔上皮化而提高鼻窦炎的治愈率。
Objective To investigate the relationship between the treatment of different maxillary sinus openings and the postoperative prognosis in endoscopic sinus surgery. Methods A total of 98 patients with chronic sinusitis and nasal polyps were randomly divided into study group (n = 52). According to the morphology of the ostium and the lesion of the maxillary sinus itself, the tissues around the ostium were treated without enlarging the ostium. The control group (n = 46) Expand the maxillary ostium, observe the two groups of ostium open rate and closure rate. Results One year after the follow-up, we found that the open rate of sinus ostium in study group and control group was 96.15% and 71.74%, respectively, and the closure rates were 3.85% and 28.26% respectively. The difference was statistically significant (P <0.01). CONCLUSIONS: The expansion of maxillary sinus stenosis and occlusion rate is higher than that of intact mucosa of sinus ostium. Endoscopic sinus surgery maintains the integrity of mucosa around the natural orifice and epithelialization of the surgical cavity to improve the cure rate of sinusitis.
