Fig. (2) Dissection of the carotid triangle of the neck illustrating the carotid arteries and their branches. Note that superior thyroid artery (STA) is arising from the common carotid artery (CCA) instead of external carotid artery (ECA). Similarly, superior laryngeal artery (SLA) is originating from the external carotid artery (ECA) instead of superior thyroid artery (STA). The position of the forceps indicates the upper border of thyroid cartilage (UBT) which is the normal level of common carotid artery bifurcation. (LA- Lingual artery, TC- Thyroid cartilage, TG- Thyroid gland, SCM- Sternocleidomastoid, ICA- Internal carotid artery, HNHypoglossal nerve, PD- Posterior belly of digastric).
