Introduction: The carcinoma of thyroid incidences is increasing rapidly in men and women. Thyroidectomy is the ultimate treatment plan for the majority of cases. The lack of knowledge about embryological and anatomical variations can cause iatrogenic injuries and leads into mortality.

Aims and Objectives: The aim was to carry out a descriptive observational study on embryological and anatomical variations in the thyroid gland through cadaver. Materials and Methods: The present study comprises an adult male human cadaver, Scalpel, forceps, scissors, and probe. The blunt dissection was carried out to clear the fat and fascia in the midline of neck region to expose the sternothyroid muscle. Loosened and transected the muscle, then examined the thyroid gland carefully.

Results: The current study has shown that the agenesis of isthmus, lobes of thyroid gland positioned more anteriorly, and the presence of levator glandulae thyroideae.

Conclusion: The lack of knowledge of embryolgical and anatomical anomalies in the thyroid gland can cause major complications during surgery and also post operatively. The complete awareness of these various anomalies helps in the accurate diagnosis and better outcomes.
