MSCT观察鼻道窦口复合体解剖变异与副鼻窦炎相关性的意义

The Significance of Multi-slice Spiral CT(MSCT) in Observation of Ostiomeatal Complex Anatomic Variation and Paranasal Sinusitis

目的过CT对鼻道窦口复合体(ostiomeatal complex,OMC)解剖变异的观察,认识鼻道窦口复合体变异与副鼻窦炎的相关性。方法使用飞利浦Brilliance 64层螺旋CT机对本院2009年-2011年经临床证实的137例副鼻窦炎患者行轴位薄层容积扫描,并进行冠状位、矢状位重建,重点观察鼻道窦口复合体区的解剖变异。结果 137例副鼻窦炎患者中:中鼻甲反向弯曲者约12.8%,中鼻甲过度气化者约32.1%,鼻中隔偏曲者约67.2%,钩突偏移者约39.1%,筛泡过度气化者约40.9%,丘鼻过度气化者约4.7%,Haller气房者约15.7%。结论 MSCT能够清晰显示鼻道窦口复合体区的解剖变异与副鼻窦炎的相关性。

Objective To realize the relationship between the variation of ostiomeatal complex （OMC） and paranasal sinusitis through CT observation about ostiomeatal complex ana- tomic wtriation. Methods Using Philips Brilliance 64 MSCT do axial thin slice volume scanning on 137 patients who has been confirmed with sinusitis by clinical in our hospital during the year 2009-201 i, then perform coronal, sagittal reconstruction and focus oil the observation about the anatomic variation of ostiomeatal complex. Results within the 137 cases of sinusitis patients： the rate of middle turbinate reverse bending is approximately 12. 8%, middle turbinate over gasification is about 32.1%, nasal septum deviation is about 67. 2%, uncinate process migration is about 39.1%, ethmoidal bulla excessive gasification in about 40.9%, agger nasi over gasification is approximately 4.7%, Haller gas room is about 15.7%. Conclusion MSCT can clearly display the correlation between anatomical varia- tion in the ostiomeatal complex and paranasal sinusitis.
