目的:介绍额窦炎性疾病鼻内引流术的类型、适应证、手术方法及疗效。方法:回顾性分析132例采用鼻内进路显微-内镜下行DrafⅠ~Ⅲ型额窦引流术、随访1~12年的患者的临床资料。结果:有效率分别为,Ⅰ型83.4%,Ⅱ型83.7%,Ⅲ型89.4%,3型疗效差异无统计学意义(P>0.05)。结论:对重症、慢性息肉性鼻窦炎以及经内镜鼻窦手术后仍复发的鼻窦炎患者,鼻内进路显微-内镜下额窦引流术可获得确切疗效。 Objective: To introduce the frontal sinusitis nasal drainage type, indications, surgical methods and efficacy. Methods: The clinical data of 132 cases of Draf Ⅰ ~ Ⅲ type frontal sinus drainage by intranasal approach microsurgery and endoscopy were retrospectively analyzed. The patients were followed up for 1 to 12 years. Results: The effective rates were 83.4% of type Ⅰ, 83.7% of type Ⅱ and 89.4% of type Ⅲ, respectively. There was no significant difference in efficacy between type 3 (P> 0.05). CONCLUSIONS: In patients with severe, chronic polyposis rhinosinusitis and sinusitis who have relapsed after endoscopic sinus surgery, endoscopic naso-endoscopic frontal sinus drainage may achieve the desired effect.
