摘要

目的:在计划鼻窦手术时,术前识别骨内后上齿槽动脉(PSAA)至关重要。本研究旨在确定骨水泥釉交界处与 PSAA 之间的距离,以及确定影响锥束计算机断层扫描(CBCT)检测 PSAA 的因素:研究人员使用两种不同的扫描仪对 254 张上颌窦 CBCT 扫描图像进行了检查,以确定 PSAA。记录每个上颌后牙位置的牙本质釉质交界处(CEJ)到 PSAA 的距离。采用二项逻辑回归和多元线性回归分别评估了扫描仪类型、CBCT参数、性别和年龄对PSAA检测和CEJ-PSAA距离的影响。P值小于0.05为统计学意义:扫描仪 1 在第二磨牙、第一磨牙、第二前磨牙和第一前磨牙位置的平均 CEJ-PSAA 距离分别为 17.0±4.0mm、21.8±4.1mm、19.5±4.7mm 和 19.9±4.9mm,扫描仪 2 的平均 CEJ-PSAA 距离分别为 17.3±3.5mm、16.9±4.3mm、18.5±4.1mm 和 18.4±4.3mm。没有自变量对 PSAA 检测有明显影响。但是,牙齿位置(b=-0.67,PPConclusion:基于CBCT的CEJ-PSAA距离估计值与之前涉及尸体、CT和CBCT的研究结果相当。CBCT 扫描仪的类型可能会对这一测量结果略有影响。没有任何自变量会对 PSAA 检测产生重大影响。

Distribution of the intraosseous branch of the posterior superior alveolar artery relative to the posterior maxillary teeth.

Purpose: Preoperative identification of the intraosseous posterior superior alveolar artery (PSAA) is critical when planning sinus surgery. This study was conducted to determine the distance between the cementoenamel junction and the PSAA, as well as to identify factors influencing the detection of the PSAA on cone-beam computed tomography (CBCT).

Materials and methods: In total, 254 CBCT scans of maxillary sinuses, acquired with 2 different scanners, were examined to identify the PSAA. The distance from the cementoenamel junction (CEJ) to the PSAA was recorded at each maxillary posterior tooth position. Binomial logistic regression and multiple linear regression were employed to evaluate the effects of scanner type, CBCT parameters, sex, and age on PSAA detection and CEJ-PSAA distance, respectively. P-values less than 0.05 were considered to indicate statistical significance.

Results: The mean CEJ-PSAA distances at the second molar, first molar, second premolar, and first premolar positions were 17.0±4.0 mm, 21.8±4.1 mm, 19.5±4.7 mm, and 19.9±4.9 mm for scanner 1, respectively, and 17.3±3.5 mm, 16.9±4.3 mm, 18.5±4.1 mm, and 18.4±4.3 mm for scanner 2. No independent variable significantly influenced PSAA detection. However, tooth position (b=-0.67, P<0.05) and scanner type (b=-1.3, P<0.05) were significant predictors of CEJ-PSAA distance.

Conclusion: CBCT-based estimates of CEJ-PSAA distance were comparable to those obtained in previous studies involving cadavers, CT, and CBCT. The type of CBCT scanner may slightly influence this measurement. No independent variable significantly impacted PSAA detection.
