BACKGROUND
Understanding the precise position and course of the superior and inferior labial arteries within the upper lip and the lower lip is crucial for safe and complication-free applications of volumizing materials.
METHODS
One hundred ninety-three anatomical head specimens (56.5 percent female cadavers) of Caucasian ethnicity were investigated in this large multicenter anatomical study. In total, six 3-cm-long vertical incisions were performed on each lip (midline and 1 cm medial to the angles of the mouth) to identify the position of the superior and inferior labial arteries in relation to the orbicularis oris muscle.
RESULTS
Three different positions of the superior and inferior labial arteries were identified: submucosal (i.e., between the oral mucosa and the orbicularis oris muscle in 78.1 percent of the cases), intramuscular (i.e., between the superficial and deep layers of the orbicularis oris muscle in 17.5 percent of the cases), and subcutaneous (i.e., between the skin and the orbicularis oris muscle in 2.1 percent of the cases). The variability in changing the respective position along the labial course was 29 percent for the total upper and 32 percent for the total lower lip. The midline location was identified in both the upper and lower lips to be the most variable.
CONCLUSIONS
Based on the results of this investigation, a safer location for the application of volumizing material is the subcutaneous plane in the paramedian location of both the upper lip and the lower lip. Care has to be taken when aiming to inject in the midline, as the artery can be identified more frequently in superficial positions.
背景
了解上唇和下唇内上唇动脉和下唇动脉的精确位置及走行，对于安全且无并发症地应用填充材料至关重要。
方法
在这项大型多中心解剖学研究中，对193例白种人种族的解剖头部标本（56.5%为女性尸体）进行了研究。总共在每个嘴唇上做了6个3厘米长的垂直切口（中线处以及口角内侧1厘米处），以确定上唇动脉和下唇动脉相对于口轮匝肌的位置。
结果
确定了上唇动脉和下唇动脉的三种不同位置：黏膜下（即78.1%的病例中位于口腔黏膜和口轮匝肌之间）、肌内（即17.5%的病例中位于口轮匝肌浅、深层之间）和皮下（即2.1%的病例中位于皮肤和口轮匝肌之间）。上唇整体和下唇整体在唇走行过程中各位置变化的变异性分别为29%和32%。上唇和下唇的中线位置被确定为变异性最大的位置。
结论
基于本研究结果，在上唇和下唇的旁正中位置的皮下平面应用填充材料是更安全的位置。在中线处注射时必须小心，因为动脉在浅表位置更常见。
