目的　探讨各型鼻窦炎内窥镜下鼻窦手术的要点及影响疗效的相关因素。方法　接受内窥镜鼻窦手术的 10 6例 (187侧 )鼻窦炎病人 ,年龄 14～ 6 0岁 ,平均 31岁 ,男 76例 ,女 30例 ,全身麻醉 9例 ,局部麻醉 97例 ,10 6例术后随访 6～ 14个月 ,随访在鼻内镜下进行 ,术后综合治疗包括 :清理术腔 ,冲洗鼻腔 ,抗生素、激素、酶制剂的应用。结果　 10 6例 (187侧 ) ,治愈 76例 (71 7% ) ,好转 2 6例 (2 4 5 % ) ,无效 4例(3 8% ) ,总有效率 96 2 %。结论　术前常规鼻窦冠位CT扫描 ,对判定病变性质、范围、指导手术有特殊意义 ,术中应避免鼻窦周围重要结构的损伤 (颅底、眶纸板、鼻泪管、视神经、大血管等 )。坚持术后综合处理是防止复发 ,获得远期疗效的主要因素。 Objective To explore the main points of sinus surgery under sinusitis and the related factors that influence the curative effect. Methods One hundred and six patients (187 sides) with sinusitis received endoscopic sinus surgery, aged from 14 to 60 years old, with an average of 31 years. There were 76 males and 30 females, 9 were general anesthesia, 97 were local anesthesia, and 10 6 Cases were followed up for 6 to 14 months, follow-up under endoscopic surgery, postoperative comprehensive treatment, including: clear the surgical cavity, nasal irrigation, antibiotics, hormones, enzyme preparation. Results 106 cases (187 sides), cured 76 cases (71.7%), improved in 26 cases (24.5%), ineffective in 4 cases (38%), the total effective rate was 96.2%. Conclusions The preoperative routine CT scan of paranasal sinus is of special significance in judging the nature, extent and guiding operation of the lesion, and should avoid the damage of the important structure around the sinuses during operation (skull base, orbital cardboard, nasolacrimal duct, optic nerve, large blood vessel) . Adhere to postoperative comprehensive treatment is to prevent recurrence, access to long-term efficacy of the main factors.
