In most cases, the superior laryngeal artery (SLA) branches from the superior thyroid artery, which, in turn, leaves the external carotid artery. Few dissection studies found previously that the SLA could originate from the lingual artery. We report here probably the first evidence of such a rare anatomical variation found unilaterally in a retrospectively evaluated by computed tomography angiography adult male case. The left SLA left a suprahyoid coil of the lingual artery and continued over the greater hyoid horn to enter the larynx through the thyrohyoid membrane. On both sides, thyroid foramina were found, but only the right one used for the entry of the right SLA. Therefore, the rare SLA origin from the lingual artery can be documented on computed tomography angiograms, which could help during preoperative evaluations and prevent unwanted surgical complications.
在大多数情况下，喉上动脉（SLA）发自甲状腺上动脉，而甲状腺上动脉又发自颈外动脉。先前的一些夹层研究发现，SLA 也可能发自舌动脉。我们在此报告一例可能是首例解剖变异的单侧病例，该病例通过 CT 血管造影术进行回顾性评估。左侧 SLA 发自舌动脉的舌骨上弓，并越过舌骨大角继续前行，穿过甲状舌骨膜进入喉内。两侧均发现有甲状舌骨孔，但只有右侧的甲状舌骨孔供右侧 SLA 进入。因此，CT 血管造影术可以记录到罕见的 SLA 发自舌动脉，这有助于术前评估并防止不必要的手术并发症。
