Abstract：
UNASSIGNED: This paper reports a rare anatomical variant of the facial artery (FA) - namely, a double FA pattern - which has significant implications in a wide range of surgical and aesthetic medicine disciplines.
UNASSIGNED: The study involves a case report and literature review of the FA and its variants. The case is that of a 61-year-old female cadaver with a unilateral FA variant branching pattern discovered during a cadaveric dissection for an anatomy course.
UNASSIGNED: The dissection revealed an unusual supply of the typical FA distribution by two separate branches from either side of the maxillary artery. The first branch, termed FA1, followed a typical FA course arising from the external carotid to supply the lower portion of the face via lingual, inferior labial, and mental arterial branches. The second branch, termed FA2, arose superior to the maxillary artery near the origin of a typical transverse facial artery, to supply the upper portion of the face via superior labial, lateral nasal, and angular arterial branches. No direct communication between the two branches was observed grossly via dissection. The observed branching pattern has not previously been reported in literature and has critical implications for surgical planning and intervention.
UNASSIGNED: This study emphasizes the importance of understanding variant FA anatomy in procedures requiring precise anatomical knowledge of arterial supply to the face. Duplicate and/or secondary facial arteries necessitate careful consideration for their potential consequences on the success of surgery of the head and neck, dermal fillers, and embolization for epistaxis procedures.

摘要：
■本文报道了面动脉（FA）的一种罕见解剖变体-即，双FA模式-在广泛的外科和美学医学学科中具有重要意义。
■该研究涉及FA及其变体的病例报告和文献综述。这种情况是61岁的女性尸体，在解剖解剖过程中发现了单侧FA变异分支模式。
■解剖显示，上颌动脉两侧的两个独立分支对典型FA分布的异常供应。第一个分支,称为FA1，遵循一个典型的FA过程，从外颈动脉通过舌侧供应面部的下部，下唇，和精神动脉分支。第二个分支,称为FA2，出现在典型的面横动脉起源附近的上颌动脉上方，通过上唇供应面部的上部，鼻侧,和有角的动脉分支。通过解剖未观察到两个分支之间的直接联系。观察到的分支模式以前没有在文献中报道过，并且对手术计划和干预具有重要意义。
■这项研究强调了在需要对面部动脉供应的精确解剖学知识的程序中理解变体FA解剖结构的重要性。重复和/或次级面部动脉需要仔细考虑它们对头颈部手术成功的潜在影响。真皮填充剂,和鼻出血栓塞术。
