目的:伴嗅觉障碍的慢性鼻-鼻窦炎患者术后嗅觉恢复的好坏各异,本研究的目的是探讨不同类型的慢性鼻-鼻窦炎术后嗅觉恢复的状况并分析嗅觉恢复欠佳的原因。方法:将276例(461)侧慢性鼻-鼻窦炎患者分成3组:不伴息肉型组;伴非嗅裂息肉型组;伴嗅裂息肉型组。采用T&T嗅觉计定量检查法对鼻内镜手术前及术后第4周、第12周、第24周进行嗅觉功能测定,对术前有嗅觉障碍者102例230侧的资料进行统计学分析。同时观察嗅觉恢复欠佳患者的鼻腔情况以查找原因。结果:①鼻内镜术后24周嗅觉恢复和好转率达86.9%。慢性鼻-鼻窦炎伴嗅裂息肉组嗅觉愈复较其他两者差(P<0.05);②术后第4周开始嗅觉恢复明显,之后变化不明显(P>0.05);③术后恢复欠佳患者鼻内镜下鼻腔有明显异常。结论:鼻内镜手术能有效改善嗅觉功能,对部分嗅觉恢复欠佳患者,与慢性鼻-鼻窦炎的分型、鼻腔-鼻窦的结构、手术中技巧以及术后用药随访有密切关系。
OBJECTIVE: Olfactory recovery in patients with chronic rhinosinusitis with olfactory dysfunction is different, and the purpose of this study is to investigate the status of olfactory recovery after different types of chronic rhinosinusitis and to analyze the reasons for the poor olfactory recovery . Methods: A total of 276 patients (461) with chronic rhinosinusitis were divided into three groups: non-PA group, non-OL group and OL group. Olfactory function was measured before and after the 4th, 12th, and 24th weeks of endoscopic sinus surgery with T & T olfactometer. The data of 102 patients with olfactory disorders before and after operation 230 were statistically analyzed. At the same time observe the poor recovery of patients with nasal smell to find the cause. Results: ① The recovery and improvement of olfactory recovery after nasal endoscopy reached 86.9% at 24 weeks. The recovery of olfactory in chronic rhinosinusitis with olfactory cleft polyps was worse than that in the other two groups (P <0.05); ② The olfactory recovery was significant at the 4th week after operation, but the change was insignificant (P> 0.05) Good patients with nasal endoscopic nasal obvious abnormalities. Conclusion: Endoscopic sinus surgery can effectively improve the olfactory function. It is closely related to the classification of chronic rhinosinusitis, nasal sinus structure, intraoperative skills and follow-up of postoperative medication for some patients with poor recovery of olfactory function.
