摘　　要：目的探讨牙根尖是否突入上颔窦与牙源性上颌窦炎患者窦腔黏膜厚度之间的CT影像学关联性。方法回顾性分析牙源性上颌窦炎患者52例(104侧)的螺旋CT影像学资料,评估上颌窦黏膜厚度与牙根尖是否突入上颌窦窦腔的关系。结果本组患者检出58侧(55.7%)有牙根尖突入窦腔,其中46侧(79.3%)存在上颌窦局部黏膜增厚大于2mm。牙根突入窦腔的上颌窦黏膜厚度(7.76±8.39mm)和无牙根突入窦腔的黏膜厚度(3.17±4.14mm)组间差异统计学意义显著(P=0.001)。结论螺旋CT影像提示,牙源性上颌窦炎患者上颌窦黏膜增厚的发生及其严重程度与牙根尖是否突入窦腔呈现明显的正相关。Objective To evaluate the association of sinus mucosal thickness with dental root apex intruding into the cavity of maxillary sinus or not among patients with odontogenic maxillary sinusitis on helical computed tomographic image. Method A retrospective study was carried out among 52 patients （104 sides） with odontogenic maxillary sinusitis, received helical computed tomography imaging to paranasal sinus to analyze the association if dental root apex being intruding into sinus cavity with sinus mucosal thickness in case of odontogenic maxillary sinusitis. Result In this group of cases, 58 sides （55.7%） were identified, based on the images, with dental root apex intruding into the cavity of maxillary sinus, and among these involved sinus, 46 sides （79.3%） were found with a local mucosal thickness thickened more than 2 mm. The thickness of cases with root apex intruding into the cavity of maxillary sinus was （7.76＆#177;8.39 mm）, significantly thicker than that （3.17＆#177;4.14 mm） of cases without root apex intruding into the cavity of sinus （P=0.001）. Conclusions As shown on helical computed tomographic images, cases with odontogenic maxillary sinusitis will have obviously thickened sinus mucosa, with its development and severity positively associated with the presence of dental root apex intruding into maxillary sinus.
