【摘要】 总结内窥镜鼻窦手术（ESS）286例，全部进行了病变临床分期、手术分级，并按分期分级统计手术效果，分组比较了术前抗生素应用对减少术中出血的作用。认为充分控制鼻腔鼻窦炎症是减少术中出血的有效措施。术中对鼻腔鼻窦病灶清除要彻底，包括必要时的经唇龈沟进路的上颌窦腔手术，还应辅以中鼻甲、下鼻甲和鼻中隔手术，充分解除鼻窦鼻腔通气引流障碍，并坚持定期细致的术后换药，及时清除鼻腔鼻窦通气引流径路上的残留性或（和）创伤性障碍，才能保障并提高ESS的手术效果。更多还原

【Abstract】 286 cases of endoscopy sinus surgery (ESS) were studied. All the cases were devided into teams according to the clinical phase of the lesion and the grading system of the operation. According to the statistics of the operation effects in different phases and grades, the effect of using antibiotics before opera-tion in decreasing bleeding during operation was compared. The discussion emphasized that the full control-ling of the inflammation of nasal cavity and nasal sinus was the effective preparation for decreasing bleeding during operation. The focuses in nasal cavity and sinus must be eliminated thoroughly during operation, and sometimes maxillary sinus operation by the entrance of labiogingival sulcus is necessary. Furthermore, in or-der to ensure and improve the effect of ESS, obstacles of nasal cavity and sinus ventilation and drainage must be completely cleared away by means of auxiliary operations related to middle turbinate, inferior turbinate and nasal septum. And after operation the dressing should be changed regularly and carefully and the remain-ing and/or traumatic obstruction in the passway of nasal cavity and sinus ventilation and drainage should be removed in time.更多还原
