STUDY OF MORPHOLOGICAL VARIATIONS OF THYROID GLAND IN ADULT HUMAN CADAVERS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 23
Abstract
BACKGROUND The thyroid is a highly vascular gland situated in front of the neck. It consists of two symmetrical lobes united by an isthmus that lie in front of 2nd, 3rd and 4th tracheal rings. The thyroid gland is the first endocrine gland to develop and takes its final shape and position at the end of the 7th week in front of the trachea. Aims and Objectives- The thyroid gland is a highly vascular endocrine gland situated in front of the neck. It consists of right and left lobes joined together by a narrow isthmus lying opposite to second, third and fourth tracheal ring. A number of morphological variation and developmental anomalies have been reported, which has numerous clinical and surgical implications. MATERIALS AND METHODS This is a descriptive study done during routine dissection of head and neck region in 32 cadavers in the Department of Anatomy, IMS and SUM Hospital of around 30 to 65 years of age for a period of 4 years. All the variations found were noted down. RESULTS It was found that the isthmus of the thyroid gland was absent in two cadavers and the two lateral lobes were completely separated. This absence of isthmus may be due to abnormality in development of thyroid gland, which may be associated with other type of disorganogenesis such as absence of lobe or presence of ectopic thyroid tissue. CONCLUSION Agenesis of thyroid isthmus has clinical, phylogenetic and surgical significance. The embryogenesis of such anomalies is discussed.
