Tortuous internal and external carotid arteries and anomalous origin of superior laryngeal artery: a case report.

Dr. Thamke Swati G, Dr. Mahesh Kurwe

Abstract :

BACKGROUND: Common carotid artery divides into external and internal carotid arteries lateral to upper border of thyroid cartilage.External carotid artery supplies structure of head and neck region by its eight named anches.Superior laryngeal artery usually arises from the superior thyroid artery which is a anch of external carotid artery.In the present case we report a rare variation of tortuosity of external and internal carotid arteries and variant origin of superior laryngeal artery.METHOD:The anteriortriangles of neck of 60-year-oldmale cadaver were studied during routine dissection for first year M.B.B.S students.

RESULTS:On right side we have found high level bifurcation of common carotid artery withextremely tortusedinternal and external carotid arteries which were �s� shaped. We also observed superior laryngeal artery originated directly from external carotid artery on the same side.These variations were compared with those reported earlier.CONCLUSION: The awareness of these variations may have proved to be paramount important to radiologists during angiography and to surgeons to avoid complication during surgery in these regions.
