The depth of the facial artery (FA) probably is the most crucial factor while performing aesthetic procedures. The course of FA varies on different levels. The knowledge of exact depth can help physicians to locate the FA more accurately, thereby enhancing the safety of filler injections. This research is the first meta-analysis focused on the quantitative comparison of depth on five different levels of facial artery including angular artery.
Twelve research papers were included in the meta-analysis. The analyses were performed in five distinctive places: (1) on the horizontal level of cheilion, (2) between oral commissure and nasal alae, (3) on the horizontal level of nasal alae, (4) between nasal alae and medial eye canthus and (5) on the horizontal level of medial eye canthus.
A total of 794, 514, 1095, 414 and 450 arteries were analyzed at the following horizontal levels, respectively: at the level of cheilion, between the nasal alae and oral commissure, at the level of nasal alae, between the nasal alae and medial eye canthus and at the level of medial eye canthus. The final results were as follows: 9.72, 95% CI (6.50-12.94) [mm], 10.34, 95% CI (5.24-15.44) [mm], 9.21, 95% CI (7.05-11.38) [mm], 4.68, 95% CI (4.04-5.31) [mm] and 2.38, 95% CI (1.38-3.38) [mm], respectively.
It appears that performing filler injections up to a depth of 4.5 mm, superficially to the facial artery, is considered safe at the level of the oral commissure. The depth between nasal alae and oral commissure varies significantly. A USG exam during the initial consultation prior to any aesthetic procedure might be a reasonable solution in the upper parts of the nasolabial fold.

在进行美容手术时，面动脉（FA）的深度可能是最关键的因素。面动脉在不同层面的走行有所不同。了解其确切深度有助于医生更准确地定位面动脉，从而提高填充注射的安全性。本研究是第一项聚焦于对面动脉五个不同层面（包括角动脉）深度进行定量比较的荟萃分析。
本荟萃分析纳入了12篇研究论文。分析在五个不同部位进行：（1）口角水平；（2）口角与鼻翼之间；（3）鼻翼水平；（4）鼻翼与内眦之间；（5）内眦水平。
在以下水平分别分析了794条、514条、1095条、414条和450条动脉：口角水平、鼻翼与口角之间、鼻翼水平、鼻翼与内眦之间以及内眦水平。最终结果如下：分别为9.72，95%可信区间（6.50 - 12.94）[毫米]、10.34，95%可信区间（5.24 - 15.44）[毫米]、9.21，95%可信区间（7.05 - 11.38）[毫米]、4.68，95%可信区间（4.04 - 5.31）[毫米]和2.38，95%可信区间（1.38 - 3.38）[毫米]。
在口角水平，似乎在面动脉浅面注射填充剂至4.5毫米深度被认为是安全的。鼻翼与口角之间的深度差异显著。在任何美容手术前的初次咨询期间进行超声检查可能是鼻唇沟上部的一个合理解决方案。
