目的 :探讨钩突变异在鼻内窥镜手术中的意义。方法 :192例鼻窦炎鼻息肉病例CT、临床诊断后 ,按Messerklinger式手术操作 ,首先切除钩突 ,再处理病灶。观察钩突变异与病变的关系。结果 :钩突变异主要有以下几种 :钩突内移或外移、钩突气化及钩突增生。钩突变异对鼻窦炎鼻息肉术后转归有明显的影响。结论 :钩突在鼻内窥镜手术中具有重要的解剖学意义。钩突骨质增生直接影响术后鼻腔鼻窦功能的恢复。术前CT检查对手术及评估疗效有指导意义 Objective: To explore the significance of the variation of hook mutation in nasal endoscopic surgery. Methods: 192 cases of sinusitis and nasal polyps CT, clinical diagnosis, according to Messerklinger-type surgical operation, the first removal of the uncinate process, and then treatment of lesions. Observe the relationship between the mutation of hook and the lesion. Results: Hook mutation mainly in the following categories: Hook shift or shift, hook gasification and uncinate process hyperplasia. Hook mutation has obvious effect on the outcome of sinusitis and nasal polyps. Conclusion: Hook process has important anatomic significance in endoscopic sinus surgery. Hypertrophy of the uncinate process directly affects postoperative recovery of nasal and sinus function. Preoperative CT examination of the operation and evaluation of the effect of guidance
