A STUDY ON VARIATION OF ORIGIN OF SUPERIOR THYROID ARTERY
S. Brooklyin, Nisha. S. R. Manuel
Abstract :
The thyroid gland is considered to be a highly vascular organ as it receives the highest quantity of blood by volume (ie) five milliliter of blood per gram of tissue. A midline structure, it is closely related to critical structures of the neck. Among the endocrine glands, the thyroid gland has an unique exceptional feature, of temporarily storing its secretions before emptying into the blood stream1. It is also the most common endocrine organ to undergo enlargement from a normal physiological goiter to a pathological goiter. Thyroid surgeries are most common neck surgeries; hence thorough knowledge of the blood supply of this gland to the surgeons is of immense importance to prevent any alarming haemorrhage2 So a sound and precise knowledge of the arterial supply of thyroid, is a prerequisite for surgical and interventional procedures of neck. Though, there are innumerable recent advances in head and neck reconstruction, a number of challenges are encountered by the reconstructive surgeon. These challenges are mainly encountered because of the visibility of this region and with presence of several structures, which have specialized functions and anatomic distinctiveness, defects are difficult to be concealed there by, indirectly increasing the demands of the surgeons`s reconstructive skills with greater emphasis on cosmesis3 . The surgical procedures of head and neck that involve superior thyroid artery include, radical neck dissection, cricothyroidotomy, thyroidectomy, reconstruction of an aneurysm, carotid endarterectomy treatments for cancer, diagnostic and therapeutic catherization and plastic surgery. The aim of the present study, is to study the possible variation in origin of superior thyroid artery. This study was conducted for a period of 12 months in the department of Anatomy, Government Medical College, Omandurar Government Estate, Chennai–2, between October 2016 – October 2017 by dissection method in 10 adult cadavers(10– right & 10– left sides) . Then results were noted, tabulated and interpreted
