摘要

背景:本研究的目的是通过锥形束计算机断层扫描(CBCT)评估接受上颌后牙槽后上动脉(PSAA)修复手术和其他鼻窦增大手术患者的牙槽后上动脉(PSAA)的位置和放射形态特征:共纳入 816 张 CBCT 扫描图像。结果:PSAA 大部分位于上颌窦内,与上颌窦底和牙槽嵴的距离较远:结果:31-51 岁年龄组(56%)、男性(53.4%)和有齿患者(57.4%)的 PSAA 大多位于骨内。年龄较大的患者动脉往往较宽。女性到窦底或牙槽嵴的距离往往较短:这项研究表明,CBCT 是一种有价值的术前工具,在 CBCT 图像上评估 PSAA 可以降低上颌后区手术中出血过多的可能性。

Assessment of neurovascular channels in lateral maxillary sinus wall using cone-beam computed tomography: An imperative clinicians guide for implant placements.

Background: The aim of this study is to evaluate the location and radio morphometric features of the posterior superior alveolar artery (PSAA) in patients undergoing rehabilitation of posterior maxilla and other sinus augmentation surgical procedures by cone-beam computed tomography (CBCT).

Materials and methods: A total of 816 CBCT scans were included. Various radio morphometric measurements were done to assess the PSAA location, diameter, and distances to the sinus floor and alveolar crest.

Results: The PSAA was mostly intraosseous in the maximum in the age group 31-51 years (56%), in males (53.4%), and in dentate patients (57.4%). The artery tends to be wider in older patients. Distances to the sinus floor or the alveolar crest tend to be shorter in women.

Conclusions: This study suggests that CBCT is a valuable pre-surgical tool and the evaluation of the PSAA on CBCT images could reduce the likelihood of excess bleeding during surgery in the maxillary posterior region.
