Abstract

During dissection of the submental region, the anterior bellies of the right and left digastric muscles were found to have two separate portions, inserting into different locations in the submental region. The lateral portions of the anterior bellies of the digastric muscles originated from the digastric fossa and inserted into the hyoid bone. The medial parts of the anterior bellies of the right and left digastric muscles ran medially and inserted into the mylohyoid raphe on both sides, forming accessory digastric muscles. This anatomic abnormality of the muscle could be significant in surgical procedures involving the submental region.

摘要

在颏下区域解剖过程中，发现左右二腹肌前腹各有两个独立部分，插入颏下区域的不同位置。二腹肌前腹的外侧部分起自二腹肌窝，止于舌骨。左右二腹肌前腹的内侧部分向内走行，止于双侧的下颌舌骨缝，形成副二腹肌。这种肌肉的解剖异常在涉及颏下区域的手术操作中可能具有重要意义。
