Implications of Anatomical and Morphological Variations of Thyroid Gland: A Case Report

Because of extreme variations in gross Anatomy of Thyroid Gland, Marshal stated that it was a difficult work to speak about normal thyroid gland [1]. Description of incidence of Pyramidal lobe, an embryological remnant of thyroglossal duct differ from 15 to 75% in Anatomical text books and data concerning its size are lacking [2, 3]. During the routine undergraduate dissection of Thyroid gland for Ist year MBBS in the Department of Anatomy, Govt. Medical college, Amritsar, India, in an elderly Male cadaver various morphological anomalies of Thyroid gland were encountered. These were in the form of presence of pyramidal lobe on left side, tip of which was attached to hyoid bone through Levator glandulae thyroidae and absence of superior thyroid artery on right side. The knowledge of various Anatomical & Morphological variation will help surgeons in forming a cornerstone to safe and effective surgeries.
