鼻内镜下上颌窦口处理方法的探讨

目的：探讨内窥镜鼻窦手术中上颌窦自然开口处理方法与预后的关系。方法：对慢性鼻窦炎、鼻息肉患者682例采用不同途径寻找上颌窦开口并根据窦口的形态和上颌窦本身的病变情况，决定开口方式与处理方法。结果：随访6个月，发现窦口开发率为84.22%(574/682例)，闭锁率为16.88%（106/682）。结论：上颌窦口的处理方法是鼻内窥镜手术重要步骤，也是影响疗效与预后的关键因素之一。

Management of the ostium of the maxillary sinus in endoscopic sinus surgery

Objective: To investigate the clinical role of the management of the maxillary sinus ostium on the prognosis in endoscopic sinus surgery (ESS). Methods: A total of 682 cases of chronic sinusitis or nasal polyp had been subjected to ESS since 2001. In the operation, the ostium was enlarged or not based on the shape and size of the ostium or ostium maxillary sinus diseases. Results: Followed up for 6 months, maxillary ostia was found in 84.22%(574/682) of the patients and maxillary ostia closure was found in 16.88%（106/682 ）of the patients. Conclusion: Patency of the maxillary ostia is one of the important criterions to evaluate ESS. Suitable management of the ostium and regular follow-up are the key points to regain the long-term patency of the ostia.
