上颌窦气化与牙源性上颌窦炎的相关性分析

Correlation analysis of maxillary sinus pneumatization and odontogenic maxillary sinusitis

目的探讨上颌窦气化与牙源性上颌窦炎发病的关系。方法回顾性分析牙源性上颌窦炎患者鼻窦CT中双侧牙槽突骨质厚度、牙槽突气化深度,冠状位上颌窦高度及矢状位对角线长度,观察牙源性上颌窦炎患者双侧上颌窦气化程度的差异。结果牙源性上颌窦炎患者患侧上颌骨牙槽突厚度:(5.67±1.79)mm,健侧上颌骨牙槽突厚度:(7.88±2.77)mm,患侧明显小于健侧。患侧牙槽突气化深度:(8.67±2.71)mm,健侧牙槽突气化深度:(6.31±3.78)mm,患侧明显大于健侧。双侧上颌窦高度及矢状位对角线长度无明显差异。健侧上颌骨牙槽突骨质厚度与牙槽突气化深度呈负相关关系,患侧上颌骨牙槽突骨质厚度与牙槽突气化深度无明显相关关系。结论牙源性上颌窦炎患者上颌骨牙槽突部位存在双侧不对称性局部气化现象,导致患侧牙槽突骨质于上颌窦底一侧的吸收变薄,可能是牙源性上颌窦炎的易感因素。

Objective To investigate the relationship between maxillary sinus pneumatization and odontogenic maxillary sinusitis.Methods Computed tomographic(CT)data of bilateral alveolar process thickness,alveolar pneumatization depth,maxillary coronary sinus height and sagittal diagonal length in patients with odontogenic maxillary sinusitis were analyzed retrospectively to observe the difference of bilateral maxillary sinus pneumatization.Results The thickness of the affected alveolar process was(5.67±1.79)mm,which was significantly thinner than that of the healthy side(7.88±2.77)mm.The depth of alveolar pneumatization of the affected side was(8.67±2.71)mm,which was significantly deeper than that of the healthy side side(6.31±3.78)mm.There were insignificant differences in neither the maxillary coronary sinus height nor sagittal diagonal length between the affected and healthy maxillary sinuses.The thickness of the alveolar process was negatively correlated with the depth of alveolar pneumatization on the healthy side,while no correlation was found on the affected side.Conclusion Asymmetric localized pneumatization of the alveolar process in patients with odontogenic maxillary sinusitis can cause the bone absorption of the affected alveolar process,which may be a susceptible factor for odontogenic maxillary sinusitis.
