Background & aim: To identify the variations in site of origin and level of the origin of the superior thyroid artery and its relation with external laryngeal nerve. Material & Method: A study was undertaken on 33 donated cadavers and through dissection was performed in neck region and both sides of superior thyroid artery were considered. Results: in present study superior thyroid artery arise...

The superior laryngeal artery (SLA) is the dominant arterial supply of the laryngeal muscles, mucosa and glands. The purpose of the present study was to document the variable origin of the SLA in the carotid triangle. Although the variation in the SLA origin and morphology is important during the partial laryngectomy and reconstruction surgery of the larynx, the description of the SLA in modern...

Introduction: A thorough knowledge of the thyroid anatomy and its associated anatomical variations is very important for the clinicians. The variations in the course of the vessels and nerves in the vicinity of the thyroid may prove to be a nightmare for surgeons. Therefore a detailed study on it equips the surgeon with vital information in the event of any such encounter. Aim & Objectives: To ...

BACKGROUND There are known to be variations in the origins of the superior thyroid artery (STA), an important surgical landmark, and 1 of its branches, the superior laryngeal artery (SLA). METHODS Three hundred thirty human embalmed heminecks were dissected. The results of previous studies were reviewed, and a meta-analysis is presented. RESULTS Four different origins for the STA were found...

With the expanding use of the ansa cervicalis nerve for laryngeal reinnervation procedures. So the aim of this work was to study the anatomical variations of ansa cervicalis in its roots, course and branching pattern. Twenty five Egyptian necks (50 sides) were dissected. The results showed that the ansa cervicalis (AC) consisted of two roots: superior and inferior roots. These two roots joined ...

The left superior laryngeal artery was observed arising from the external carotid artery instead of the superior thyroid artery in the cadaver of an approximately 70 year-old Asian man. In addition, on the same side, the superior thyroid artery arose from the common carotid artery 2 cm before the bifurcation instead of its usual origin from the external carotid artery. From the external carotid...

The superior laryngeal artery is the primary vessel providing blood supply to larynx. Commonly, it derived from thyroid artery. Different variations in origin have been described current literature; knowledge of such crucial for various surgical interventions larynx and procedures lateral region neck regarding carotid triangle. It should be noted that radiological studies, as selective angiogra...

Though the variations in the carotid arteries and their branches are common in the carotid triangle, it is important for the clinicians, surgeons and the radiologists to be aware of all possible variations of these arteries. A case of abnormal origin of 2 important arteries encountered during routine dissection of carotid triangle of the neck is reported. The superior thyroid artery that normal...
