【摘要】：目的:通过锥体束CT(CBCT)来分析评估上颌窦外侧壁骨内吻合血管情况,为上颌窦外侧开窗提升术提供指导。方法:共纳入无上颌窦疾病的患者238例(476个上颌窦),其中108例存在上颌后牙缺失。通过CBCT影像学资料分析评估上颌窦外侧壁骨内吻合血管的直径、血管下缘到牙槽嵴顶的距离、血管内壁到上颌窦内侧壁的距离、上颌窦底到牙槽嵴顶的距离,并且比较后牙留存和后牙缺失情况下该血管的位置变化。结果:上颌窦中骨内吻合血管的检出率为39.08%(186/476)。血管直径为(1.33±0.56)mm,男性血管直径大于女性,50~岁和60岁以上年龄组血管直径大于其他年龄组(P0.05)。血管下缘到牙槽嵴顶的距离为(13.01±1.60)mm,女性小于男性,后牙缺失组小于后牙留存组(P0.05),但各年龄组间差异无统计学意义(P0.05)。血管内壁到上颌窦内侧壁的距离男性大于女性(P0.05),但各年龄组间差异无统计学意义(P0.05)。结论:应用CBCT可以有效发现上颌窦外侧壁骨内吻合血管的存在。建议行上颌窦手术之前应进行CBCT检查以避免术中损伤骨内吻合血管。
[Abstract]:Objective: to evaluate the intraosseous anastomosis of lateral maxillary sinus by CT-CBCT and to provide guidance for lateral fenestration of maxillary sinus. Methods: a total of 238 patients without maxillary sinus disease were included in this study. The diameter of intraosseous anastomosis, the distance from the inferior margin to the alveolar crest, the distance from the inner wall of the vessel to the medial wall of the maxillary sinus and the distance from the bottom of the maxillary sinus to the top of the alveolar crest were evaluated by CBCT imaging data. The location of the vessel was compared between the retained posterior teeth and the absence of posterior teeth. Results: the detection rate of intraosseous anastomosis in maxillary sinus was 39.08 / 476%. The diameter of blood vessel in male was 1.33 卤0.56 mm. The diameter of blood vessel in male group was larger than that in female group aged 50 ~ 60 years and over 60 years old, and the diameter of male group was larger than that of other age group (P 0.05). The distance from the inferior edge of blood vessel to the top of alveolar ridge was 13.01 卤1.60 mm. The distance between female and male was less than that of male, and that of the group with missing posterior teeth was smaller than that of retained posterior teeth (P0.05), but there was no significant difference among different age groups (P 0.05). The distance from the inner wall of the vessel to the medial wall of the maxillary sinus was greater in males than in females, but there was no significant difference among different age groups. Conclusion: intraosseous anastomosis of lateral wall of maxillary sinus can be effectively detected by CBCT. CBCT should be performed before maxillary sinus surgery to avoid intraosseous vascular anastomosis.
