Infrahyoid muscles are usually supplied by muscular arteries, originating from the superior and inferior thyroid artery and the internal thoracic artery. In this work, we reported a unilateral anatomical variation of the branching pattern of the lingual artery, which was observed during dissection studies at the University of Brescia. We found an accessory branch arising from the root of the lingual artery that run down medially and supplied the infrahyoid muscles. A similar case has not yet been reported in literature. Considering the current use of the infrahyoid muscles as pedicled myocutaneous flap for reconstructing surgical defects in the head and neck, this vascular variation appears interesting to be reported for appropriate clinical and surgical consideration.
舌骨下肌群通常由肌动脉供血，这些肌动脉起源于甲状腺上、下动脉以及胸廓内动脉。在这项研究中，我们报告了在布雷西亚大学解剖研究过程中观察到的舌动脉分支模式的单侧解剖变异。我们发现一条副支从舌动脉根部发出，向内下行并供应舌骨下肌群。文献中尚未报道过类似病例。考虑到目前将舌骨下肌群用作带蒂肌皮瓣来修复头颈部手术缺损的情况，报道这种血管变异对于临床和手术的恰当考量似乎很有意义。
