鼻内镜中鼻道联合下鼻道上颌窦开窗术径路治疗上颌窦良性病变的回顾性分析

摘要：目的??探讨应用鼻内镜中鼻道上颌窦开窗术（MMA）联合下鼻道上颌窦开窗术（IMA）径路治疗上颌窦良性病变的可行性和临床效果。方法?回顾性分析2008年6月－2015年8月治疗的51例上颌窦良性病变临床资料。在常规行鼻内镜下MMA术后，对于难以完整切除的病变联合IMA术切除病变。记录术中情况及术后疗效。结果?术中内镜下能很好地观察和切除上颌窦内各壁病变。术中及术后无鼻泪管损伤、鼻甲萎缩和局部感染等并发症。术后随访6个月以上，临床症状逐步消失，窦内黏膜上皮化，窦口引流通畅，病变无复发。结论?MMA联合IMA可以很好地治疗上颌窦良性病变，尤其在上颌骨囊肿治疗中有很大应用空间。

Retrospective analysis of endoscopic sinus surgery through the approach MMA combined with IMA in treatment of benign maxillary lesions

Abstract: Objective?To explore the feasibility and clinical efficacy of endoscopic sinus surgery through the approach combined with inferior nasal meatus in treatment of benign lesions of maxillary sinus.?Methods?Clinical data of 51 cases with benign lesions of maxillary sinus from June 2008 to August 2015 were analyzed retrospectively. We combined IMA to resect residual lesion after MMA, meanwile, we recorded the clinical efficacy on operation and after operation.?Result?Combined with IMA, endoscopic surgery can observe and resect benign lesions of every wall of maxillary sinus well. No complication occurred, such as nasolacrimal duct injury, turbinate atrophy, and infection. After 6 months following-up, all the patients symptoms disappeared gradually, with satisfactory epithelization in maxillary sinus cavities, and with smooth drainage. There is no reccurence of the lesions.?Conclusion?MMA combined with IMA can treat benign lesions of maxillary sinus well, and it can play a main role in treatment of maxilla cyst.
