摘要

目的分析上颌窦在 CBCT 图像上的各种解剖特征,主要是后牙槽上动脉 (PSAA),并比较其在 CBCT 图像与全景图像上的可见度:对 120 名患者(240 个上颌窦)的 CBCT 冠状切面(CCV)和全景照片(CP)进行了回顾性放射学分析。在 CCV 上,分别分析了 PSAA 的最大尺寸(MD)、到牙槽嵴的垂直距离(PVD)以及 PSAA 颊侧和下侧的骨板厚度(T1 和 T2)。此外,还记录了CCV的骨桥垂直距离(OVD)和位置,并测量了上颌窦下剩余骨高度(MVD)。对 PSAA 的能见度进行评估,并在 CCV 和 CP 之间进行比较。所有这些变量都是在上颌第二前磨牙(P2)、第一磨牙(M1)和第二磨牙(M2)的根尖区域进行研究的。研究还调查了影响上颌窦尺寸和能见度的年龄、性别和脸侧(右侧和左侧)因素。分析这些变量时使用了多种统计检验方法:CCV在96.53%的记录中检测到了PSAA,在所有分析部位,CCV在检测PSAA结构方面明显优于CP(P值为0.000)。PSAA 的 MD、PVD、T1 和 T2 厚度以及 MVD 平均值分别为 1.19 毫米、19.54 毫米、0.69 毫米、1.36 毫米和 10.25 毫米。OVD平均为31.04毫米,其中42.9%的骨孔位于第二上磨牙的中线范围内。不同年龄组、性别和 PSAA 可见度之间没有发现明显的关系:结论:在所研究的巴勒斯坦样本中,年龄、性别和所调查的脸侧对上颌窦的骨厚度、垂直尺寸或 PSAA 直径没有明显影响。由于 CCV 在识别 PSSA 方面优于 CP,因此建议使用 CBCT 容量对 PSSA 进行术前评估。

Maxillary sinuses, multiple aspects to consider prior to bone grafting procedure: a retrospective study in a sample of a Palestinian population.

Maxillary sinuses, multiple aspects to consider prior to bone grafting procedure: a retrospective study in a sample of a Palestinian population.

Objectives: To analyze various anatomical aspects of the maxillary sinuses on CBCT volumes, mainly, the posterior superior alveolar artery (PSAA), and to compare its visibility on CBCT vs. panoramic radiographs.

Material and methods: A retrospective radiographic analysis was conducted on 120 patients (240 maxillary sinuses) using their CBCT coronal views (CCV) and panoramic radiographs (CP). On CCV, the PSAA's maximum dimension (MD), vertical distance (PVD) to the alveolar crest, and bone plate thickness (T1 and T2) buccally and inferiorly to the PSAA, respectively, were analyzed. Additionally, on CCV, the ostium vertical distance (OVD) and location were recorded, and the height of the remaining bone height inferior to the maxillary sinuses (MVD) was also measured. The PSAA's visibility was evaluated and compared between CCV and CP. All these variables were studied at the apical region of the second maxillary premolar (P2), first molar (M1), and second molar (M2). Age, gender, and face side (right vs. left) factors affecting the sinus dimensions and visibility were investigated. Several statistical tests were used to analyze these variables.

Results: PSAA was detected in 96.53% of the records on CCV, where it was significantly superior to CP in the detection of the PSAA structure (p value 0.000) at all sites analyzed. The PSAA's MD, PVD, T1 and T2 thicknesses, and MVD were on average 1.19 mm, 19.54 mm, 0.69 mm, 1.36 mm, and 10.25, respectively. OVD average was 31.04 mm where 42.9% of the ostia were within the mesiodistal extent of the second upper molar. No significant relation was found between different age groups, gender, and the visibility level of PSAA.

Conclusion: Age, gender, and the side of the face investigated showed no discernible effects on the maxillary sinus's bone thickness, vertical dimensions, or PSAA diameter among the studied Palestinian sample. As CCV was superior to CP in the identification of PSSA, preoperative evaluation of PSSA using CBCT volumes is thus recommended.
