摘要/Abstract

摘要： 目的运用CBCT影像资料观察统计上颌窦外侧壁牙槽管的解剖学特点,为临床实践提供参考。方法从山东大学口腔医学院CBCT数据库搜集寻找符合纳入标准的病例资料150例,运用GALAXIS软件观察并统计上颌窦外侧壁牙槽管走行、骨内吻合发生率、在各位置的检出率、直径、距牙槽嵴顶距离。结果牙槽管走行类似尖向下的折线,观测到骨内吻合的概率为84.33%,上颌窦外侧壁牙槽管最前点观测到的概率为95%,平均直径为(1.05±0.36)mm,距牙槽嵴顶的平均距离为(28.04±2.44)mm,最后点观测到的概率为93.33%,平均直径为(0.89±0.29)mm,距牙槽嵴顶的平均距离为(18.86±2.78)mm,前后点直径相比差异具有统计学意义(P<0.05),在上颌窦中部外侧壁观测到牙槽管的概率为63.00%,只有1.08%的牙槽管直径>2 mm。结论上颌窦外侧壁存在牙槽管,因其直径较小及位置不定,常不易发现,在手术操作中可能引起出血等并发症;运用CBCT能有效对其进行观测。

Abstract: Objective To investigate the anatomic characteristics of the maxillary sinus lateral wall alveolar canal with cone-beam CT(CBCT)imaging data and to provide reference for clinical practice. Methods A total of 150 cases which met the inclusion criteria were collected from the CBCT database of Stomatology Hospital of Shandong University. The GALAXIS software was used to observe and analyze the lateral wall alveolar canal of the maxillary sinus, shape of the canal, incidence of intraosseous anastomosis, detection rate in each location, diameter of the canal as well as the distance from the lower border to the alveolar crest. Results The alveolar canal was like a downward fold line, with the incidence of intraosseous anastomosis being 84.33%. Incidence of the front point of the alveolar canal was 95%, with an average diameter of(1.05±0.36)mm and(28.04±2.44)mm to the alveolar crest. The figure for rear point was 93.33%, with an average diameter of(0.89±0.29)mm and(18.86±2.78)mm to the alveolar crest. The difference in the diameters of two points was statistically significant(P<0.05). The incidence of the alveolar canal in the middle region of the maxillary sinus lateral wall was 63.00%, and only 1.08% of the alveolar canal had the diameter >2 mm. Conclusion The alveolar canal exists in the maxillary sinus lateral wall and it is difficult to detect the canal due to the small diameter and uncertain location. Bleeding and other complications may occur when it is damaged in surgical procedures. It can be observed effectively by the use of CBCT.
