MORPHOMETRY OF THE THYROID GLAND IN DIFFERENT AGE GROUPS IN NORTH INDIAN POPULATION: A CADAVERIC STUDY

Aims and Objectives: The present study was conducted to find out morphometry of thyroid gland in different age groups. Material and Methods: The study was conducted on 60 human thyroid glands in the Department of Anatomy, Pt. B. D. Sharma, PGIMS, Rohtak in North Indian population. Results: In present study, mean length of right and left lobe of thyroid gland was found to be 29.88±7.03 mm and 29.45±5.44 mm in Group A, 41.33±6.95 mm and 38.87±5.04 mm in Group B, 35.02±3.98 mm and 31.77±3.27 mm in Group C respectively. The mean width was observed as 18.76±4.23 mm and 20.77±6.01 mm in Group A, 24.13±4.77 mm and 22.47±2.72 mm in Group B, 21.54±2.05 mm and 20.72±2.53 mm in Group C respectively in right and left lobes. The mean thickness was 13.70±4.69 mm and 13.60±4.51 mm in Group A, 15.19±1.99 mm and 15.01±2.29 mm in Group B, 14.73±1.99 mm and 14.09±2.33 mm in Group C respectively in right and left lobes. The mean length and height of the isthmus of thyroid gland was found to be 12.38±4.19 mm and 10.85±5.34 mm in group A, 14.67±2.17 mm and 13.24±5.06 mm in group B, 13.51±1.89 mm and 9.72±2.40 mm in group C respectively. Conclusion: The study concluded that mean length and width of right lobe and mean length of left lobe of the thyroid gland was higher in Group B>Group C>Group A. The change in mean height of isthmus of thyroid gland was found to be significant in all the experimental groups.
