Detailed knowledge of middle temporal vein (MTV) anatomy would benefit health care professionals when performing filler injection and reconstructive surgery. The purpose of this study was to assess the variation and course of the MTV using computed tomographic angiography.
Computed tomographic angiography images of 300 MTVs from 150 Asian patients were evaluated in this study. The course and branching pattern of the MTVs were evaluated, as well as the relationship between the location of the MTV and the frontal branch of the superficial temporal artery. The diameter of the MTV and the distances between anatomic landmarks and temporal vessels were measured.
The MTV was identified in all images, with an average diameter of 2.98 ± 0.80 mm. All MTVs had at least one major trunk; 12.3% had two major trunks. According to the landmarks, the MTV ran 16.3 ± 8.1 mm, 24.8 ± 4.5 mm, and 24.2 ± 4.6 mm above bony lateral canthus, jugale, and zygion point, respectively. Regarding the relationship between the MTV and the frontal branch of the superficial temporal artery, most of the superficial temporal arteries (81.7%) were located above the MTVs, whereas only 9.0% of the superficial temporal arteries crossed the MTVs. The superficial temporal artery was located 43.5 ± 9.6 mm, 44.3 ± 11.9 mm, and 37.0 ± 11.9 mm above the bony lateral canthus, jugale, and zygion point, respectively.
Detailed knowledge of MTV anatomy will provide a valuable reference for safe filler injection and reconstructive surgery in the temporal region.

详细了解中间颞静脉（MTV）解剖结构将使医疗保健专业人员在进行填充物注射和重建手术时受益。本研究的目的是使用计算机断层血管造影术评估 MTV 的变化和走行。
本研究评估了 150 名亚洲患者的 300 条 MTV 的计算机断层血管造影图像。评估了 MTV 的走行和分支模式，以及 MTV 与额浅动脉额支的位置关系。测量了 MTV 的直径以及解剖标志与颞部血管之间的距离。
所有图像均识别出 MTV，平均直径为 2.98±0.80mm。所有 MTV 均有至少一条主干；12.3%有两条主干。根据标志，MTV 在骨性外眦、颧骨和颧突点上方分别走行 16.3±8.1mm、24.8±4.5mm 和 24.2±4.6mm。关于 MTV 与额浅动脉的关系，大部分额浅动脉（81.7%）位于 MTV 上方，而只有 9.0%的额浅动脉穿过 MTV。额浅动脉在骨性外眦、颧骨和颧突点上方的位置分别为 43.5±9.6mm、44.3±11.9mm 和 37.0±11.9mm。
详细了解 MTV 解剖结构将为颞部安全填充物注射和重建手术提供有价值的参考。
