The aim of this study was to clarify the morphology of the mylohyoid branch of the inferior alveolar artery and the main blood supply to the mylohyoid muscle.
The maxillary artery (MA) and inferior alveolar artery (IAA) within the infratemporal fossa, the facial and submental arteries within the submandibular triangle, and the nerve to the mylohyoid muscle and related artery were dissected in twelve sides from embalmed cadaveric heads. The main blood supply to the extraoral (inferior) surface of the mylohyoid muscle was recorded.
The mylohyoid branch of the inferior alveolar artery was an anastomosis of the descending branch of either the inferior alveolar or maxillary artery and the ascending branch of either the submental or facial artery. The anastomosis was classified into four types according to the origins of the arteries. The main blood supply to the extraoral surface of the mylohyoid muscle was the submental artery.
The results of this study indicate that the mylohyoid branch of the IAA in human adults is an anastomosis of branches of the maxillary and facial arteries.
本研究旨在阐明下颌舌骨肌支的下颌下动脉和下颌舌骨肌主要血液供应的形态。
在十二侧防腐尸体头颅中解剖翼腭窝内的上颌动脉（MA）和下颌下动脉（IAA）、下颌下三角内的面动脉和颏下动脉以及下颌舌骨肌神经和相关动脉。记录下颌舌骨肌外（下）表面的主要血液供应。
下颌下动脉的下颌舌骨肌支是下颌下动脉或上颌动脉的降支与颏下动脉或面动脉的升支吻合而成。根据动脉起源，吻合可分为四型。下颌舌骨肌外表面的主要血液供应来自颏下动脉。
本研究结果表明，成人下颌下动脉的下颌舌骨肌支是上颌动脉和面动脉分支的吻合支。
