The facial artery is the main artery supplying blood to the face and is known to have facial branches of the inferior labial, superior labial, lateral nasal and angular arteries. These known major branches of facial artery run medially, however, there are sometimes branches of the facial artery heading laterally. The purpose of the present study was to investigate the lateral branches of the facial artery in face. We dissected facial branches of the facial artery in 74 cadaveric hemifaces. We investigated the presence of the lateral branches of the facial artery. Following parameters were investigated: lateral branch presence, the location of its origin, and the lateral branch diameter. Among the lateral branches, we evaluated the prevalence and diameter of the premasseteric branch. Lateral branches were observed in 48 of the 74 hemifaces (64.9%). The total number was 81 in the 48 hemifaces. The most common origin was between the inferior border of the mandible and inferior labial artery origin (42 of 81, 51.9%). The mean diameter of all lateral branches of the facial artery was 0.7 mm. Among the lateral branches, the premasseteric branches were present in 38 of 74 specimen (51.4%) and the mean diameter was 0.8 mm. The lateral branches of the facial artery may be registered in Terminologia Anatomica based on their prevalence. Accurate knowledge of the anatomy of the lateral branches of the facial artery is helpful for clinicians to avoid complications during facial procedures or maxillofacial surgeries.
面动脉是供应面部血液的主要动脉，已知有下唇、上唇、鼻翼和角动脉等面动脉分支。这些已知的面动脉主要分支向内侧走行，但有时也有面动脉的分支向外侧走行。本研究的目的是探讨面动脉在面部的外侧分支。我们在 74 个半侧面标本中解剖了面动脉的分支。我们调查了面动脉外侧分支的存在情况。研究了以下参数：外侧分支的存在、其起源位置和外侧分支的直径。在这些外侧分支中，我们评估了咬肌前支的出现率和直径。在 74 个半侧面中，有 48 个（64.9%）观察到了外侧分支。在这 48 个半侧面中，外侧分支的总数为 81 个。最常见的起源部位是下颌骨下缘和面动脉下唇支起点之间（42/81，51.9%）。所有面动脉外侧分支的平均直径为 0.7mm。在这些外侧分支中，38 个（51.4%）标本存在咬肌前支，平均直径为 0.8mm。面动脉的外侧分支可以根据其出现率在 Terminologia Anatomica 中登记。准确了解面动脉外侧分支的解剖结构有助于临床医生在面部手术或颌面部手术中避免并发症。
