A Morphometric Study Of The Thyroid Gland In Human Cadavers

ABSTRACT

Introduction: The size and shape of the thyroid gland may alter remarkably with age, gender, physiologicalcondition, race, and geographical location. Thus the knowledge of the various parameters and position ofthyroid gland are important while doing surgeries on thyroid gland as well as during tracheostomy in emergencycondition.Materials and methods: The study was structured to investigate the morphometric as well as topographicalfeatures of the thyroid gland in 100 cadavers (58 males and 42 females) from Maharashtrian populationResult: The right lobe of the thyroid gland was found to be larger than the left lobe. An average length and widthof isthmus were 1.38 cm and 1.02 cm. An average weight of thyroid gland was 14.5grams. The P value was 0.00it shows that gender wise difference in different parameters was highly significant. Most commonly the isthmuswas lying opposite to 1st 2nd and 3rd tracheal rings. Gender wise difference in position of isthmus was statisticallyinsignificant.Conclusion: This study highlights the various parameters of thyroid gland as well as shows the gender wisedifference in it.
