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
