Thyroid gland is a very important endocrine gland. Thyroid gland surgery is one of the more common surgical interventions in the head and neck region.
Aim: Accurate knowledge of morphometry of the gland and its variations is important during tracheostomy and thyroidectomy. Various thyroid diseases like goitre, thyrotoxicosis, adenoma, carcinoma etc are usually associated with enlargement and require surgical intervention.
Materials and Methods: The study was done at the Department of Anatomy, Sri Ramachandra Medical College and Research Institute.50 thyroid glands dissected out from adult cadavers and also specimens utilised for teaching were used. Specimens with signs of thyroid diseases were excluded from the study.
Observation: For the 50 specimens the maximum length of the right and left lobe was 6.34cm, 5.29cm, the minimum length of the right and left lobe was 2.80cm, 2.95cm, the maximum breadth of the right and left lobe was 3.55cm, 3cm, the minimum breadth of right and left lobe was 1.24cm, 1.03cm. the maximum thickness of right and left lobes was 2.40cm, 0.89cm, the minimum thickness of right and left lobes was 2.01cm, 0.72cm, the maximum weight was 55gms, the minimum weight was 6gms, the maximum volume was 70ml, the minimum volume was 5ml.
Conclusion: Hence this study on morphometry of the gland will hopefully help to minimise the complications during surgeries.
