Fig. (3) 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 forceps is showing the internal laryngeal nerve (ILN) which accompanies the superior laryngeal artery (SLA) to pierce the thyrohyoid membrane. (TG- Thyroid gland, SCM- Sternocleidomastoid, ICAInternal carotid artery, HN- Hypoglossal nerve, PD- Posterior belly of digastric).
