OBJECTIVE
To assess the effect of middle turbinate (MT) and ethmoidal internal wall(EIW) moved externally after microsurgery.
METHODS
Twenty-four cases (45 sides) were followed-up endoscopically for (16.3 +/- 9.3) months. Thirteen cases (24 sides) were observed by CT scans. Three cadaver heads were measured for anatomical analysis.
RESULTS
Forty-one (91%) of 45 sides obtained better olfactory function after operation. Twenty-two (91%) of 24 sides were found to have better CT changes in sinus ventilation as compared with preoperative CT scans. The gap between the MT and EIW to the orbital wall was (12.0 +/- 1.0) mm, while that between the ethmoidal bulla and processus uncinatus was only (2.3 +/- 0.6) mm as revealed in the autopsy.
CONCLUSION
MT and EIW moderately moved suitably to externally had no bad effect on sinus ventilation, and it improved olfaction.
目的
评估显微手术后中鼻甲（MT）和筛窦内壁（EIW）向外移位的效果。
方法
对24例（45侧）患者进行了（16.3±9.3）个月的内镜随访。对13例（24侧）进行了CT扫描观察。对3个尸体头部进行测量以进行解剖学分析。
结果
45侧中的41侧（91%）术后嗅觉功能改善。与术前CT扫描相比，24侧中的22侧（91%）鼻窦通气的CT表现更佳。尸检显示，中鼻甲与筛窦内壁至眶壁的间隙为（12.0±1.0）mm，而筛泡与钩突之间的间隙仅为（2.3±0.6）mm。
结论
中鼻甲和筛窦内壁适度向外移位对鼻窦通气无不良影响，且可改善嗅觉。
