单侧上颌窦真菌球患者上颌窦解剖参数的CT研究

Relationship between maxillary sinus anatomical parameters and unilateral maxillary sinus fungus ball:A computed tomography study

目的探讨单侧上颌窦真菌球(UMFB)与上颌窦解剖参数的关系。方法回顾性分析55例UMFB患者的鼻窦CT资料,应用Mimics 21.0软件对双侧上颌窦进行三维重建,同时测量计算患侧与健侧上颌窦的容积、表面积、气化系数、骨壁厚度及密度等解剖参数,并对得到的数据进行统计学分析。结果①UMFB患者的双侧上颌窦中,患侧上颌窦容积、内表面积、气化系数、上下径均较健侧小,差异具有统计学意义(P<0.05),而左右径、前后径的差异无统计学意义(P>0.05);患侧上颌窦骨壁厚度及密度均较健侧大,差异具有统计学意义(P<0.05);②UMFB患侧上颌窦解剖参数与Lund-Mackay评分均无相关性(P>0.05)。结论UMFB更好发于上颌窦容积、表面积、气化系数以及上下径较小的一侧。上颌窦骨壁厚度及密度增大对于诊断UMFB具有一定价值。

Objective To investigate the relationship between the unilateral maxillary sinus fungus ball(UMFB)and maxillary sinus anatomical parameters.Methods The computed tomography(CT)data of 55 patients with UMFB were retrospectively analyzed.The software Mimics 21.0 was used for the three-dimensional reconstruction of bilateral maxillary sinuses.The volume,surface area,gasification coefficient,bone wall thickness,and density of the affected and healthy maxillary sinuses were measured and calculated,and the obtained data were statistically analyzed.Results①In the UMFB patients,the volume,internal surface area,gasification coefficient,and superior-inferior diameter of the affected side were all smaller than those of the healthy side,and the differences were statistically significant(P<0.05),but there were no significant differences in the left-right diameter and anterior-posterior diameter(P>0.05).The thickness and density of the maxillary sinus bone wall on the affected side were higher than those on the healthy side(P<0.05).②There were no correlations between the anatomic parameters of the maxillary sinus and the Lund-Mackay score on the affected side of UMFB(P>0.05).Conclusions UMFB is more likely to occur on the side with a smaller volume,surface area,gasification coefficient,and superior-inferior diameter of the maxillary sinus.The increased thickness and density of maxillary sinus bone wall have certain diagnostic value for UMFB.
