Abstract : Introduction The thyroid gland is the largest endocrine gland. It is a highly vascular gland located in the lower half of the front of neck at a level of 5th cervical to 1st thoracic vertebrae. The gland has 2 lateral lobes connected by isthmus. The thyroid lobes are connected by an isthmus, mostly positioned anterior to the 2nd–4th tracheal rings.  Aim To study the morphology and variations of thyroid gland.  Materials & Methods The current study was conducted on 20 human cadavers of both sex in the Department of Anatomy, KAHER’s Jawaharlal Nehru Medical College, Belagavi over a period of 1 year. The cadavers were preserved in 10% formalin.  Result The isthmus was absent in 10% of cases. In 30% cases it was related to the 2nd to 3rd tracheal rings. In 20% cases it was related to 1st to 2nd tracheal rings. In 5% case it was related to 1st to 4th tracheal rings. In 15% cases it was related 1st to 3rd tracheal rings. In 15% cases it was related to 2nd to 4th tracheal rings. The pyramidal lobe was present in 5% of cadavers arising from the left lobe.  Conclusion The present study showed that the mean length of the right lobe is more than the left lobe. Estimation of size of thyroid gland is clinically relevant in evaluation of any thyroid disorder. The variations in the thyroid gland along with the thorough information related to the anomalies can be of great importance to the surgeons so that there is better, planned & effective surgery.
