内镜经泪前隐窝入路治疗上颌窦前内下壁病变

目的　探讨鼻内镜下经泪前隐窝径路治疗上颌窦病变的临床效果。 方法　回顾性分析了2008年1月~2018年1月三家医院耳鼻咽喉头颈外科收治的采用内镜辅助下经泪前隐窝入路治疗的各种上颌窦病变患者67例的临床资料。 结果　上颌窦内下壁囊肿20例，上颌窦内下壁息肉6例，内翻性乳头状瘤2例，真菌球性鼻-鼻窦炎23例，变态反应性真菌性鼻-鼻窦炎13例，慢性侵袭性真菌性鼻-鼻窦炎1例。所有患者术后定期随访半年以上未见复发。 结论　鼻内镜下泪前隐窝入路能够充分显露上颌窦腔，彻底切除上颌窦内的病变，手术操作方便，能够有效治疗上颌窦各种良性病变，如有明显的泪前隐窝及齿槽隐窝存在，可作为上颌窦前内下壁病变的首选手术入路。

Endoscopic treatment the diseases of anterior medial and inferior wall of maxillary sinus by prelacimal recess approach

Objective　To investigate the clinical effect of the treatment on the diseases of anterior medial and inferior wall of maxillary sinus by endoscopic prelacimal recess approach.　Methods　The clinical data of 67 patients with various maxillary sinus lesions treated by crypt in the treatment of various maxillary sinus lesions were analyzed retrospectively in the three hospitals from January 2008 to January 2018.　Results　Twenty cases of lower wall cysts in the upper jaw sinus, 6 cases of lower wall polyps in the upper jaw sinus, 2 cases of internal epithelial papilloma, 23 cases of fungal globular sinusitis, 13 cases of allergic reactive fungal sinusitis, 1 case of chronic aggressive fungal sinusitis. All patients were followed-up regularly after surgery for more than half a year without relapse.　Conclusions　The prelacrimal recess approach under nasal endoscope can fully expose the maxillary sinus cavity and completely remove the lesions in the maxillary sinus. The operation is convenient and can effectively treat various benign lesions of the maxillary sinus, such as obvious prelacrimal recess and alveolar recess, it can be used as the first choice of surgical approach for maxillary sinus anterior medial inferior wall lesions.
