The anterior digastric muscle belly (ADMB) may present significant variations of substantial surgical importance. We present an unusual complex bilateral asymmetry of an accessory ADMB found when dissecting the submental area in a 72-year-old Greek male cadaver. A rare variant was recognized in the submental area constituted by a combination of bilateral asymmetry of the ADMB with unilateral absence of the intermediate tendon. The complex variant caused an obvious morphological asymmetry in the submental area. Such muscular variations may alter the surgical approach to the submental region. Clinicians involved in the treatment of this area should be aware of any possible variant, particularly when dealing with neck mass patients.
二腹肌前腹（ADMB）可能存在具有重要手术意义的显著变异。我们报告了一例不寻常的复杂双侧不对称性副ADMB，该情况是在对一名72岁希腊男性尸体的颏下区域进行解剖时发现的。在颏下区域发现了一种罕见的变异，其由ADMB的双侧不对称与中间腱单侧缺如相结合构成。这种复杂变异导致了颏下区域明显的形态不对称。此类肌肉变异可能会改变对颏下区域的手术入路。参与该区域治疗的临床医生应知晓任何可能的变异情况，尤其是在处理颈部肿块患者时。
