“…In the present study, the isthmus of the thyroid gland was absent in 17.8% cases. The findings of the present study is higher than that of Marshall (1995) 4 , Enayetullah (1996), 8 Begum (2004), 10 Pastor et al (2006) 11 and much lower than that of Sultana et al (2011) 12 .…”

“…Statistically significant difference was found in breadth between group A & B and A & C and in thickness between group B & C (Table 4). Marshall (1895), 4 Enayetullah (1996), 8 Begum (2004), 10 Pastor et al (2006) 11 and Sultana et al (2011) 12 observed the absence of the isthmus in 10%, 4%, 0%, 5-10% and 31.66% of cases respectively. In the present study, the isthmus of the thyroid gland was absent in 17.8% cases.…”

“…According to Berkovitz (2005) 1 , the isthmus is usually placed anterior to the second and third tracheal cartilages. Sultana (2011) 12 found that the most common locations were 1 st to 3 rd and 2 nd to 4 th tracheal ring (18.3% in both cases). The present study reported that it extends from 2 nd to 4 th tracheal ring in 91.7% cases and from 2 nd to 5 th ring in 8.3% cases; that former finding is much higher than that of the previous studies, whereas the latter is much lower.…”

Background: The position and size of isthmus of thyroid vary greatly in humans, and sometimes it is absent. The present study was designed to find out the difference in isthmus of the thyroid gland of Bangladeshi people in relation to age and sex. Methods: The cross-sectional, descriptive study was performed in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2008, on 73 post mortem human thyroid gland collected from unclaimed dead bodies. Isthmus was found in 60 cases. The samples having the isthmus (n=60) were divided into three age-groups including group A (10-20 years), group B (21-50 years) & group C (>50 years) and the isthmus was cut off from the thyroid gland, then its length, breadth and thickness were measured and recorded. Results: The isthmus of the thyroid gland was found in 82.2% cases. It extended from 2nd to 4th tracheal ring in 91.7% and from 2nd to 5th ring in 8.3% cases. No difference was found in length, breadth and thickness of the isthmus of the thyroid gland in between males and females. However, difference was found in breadth between group A & B (p<0.05) and A & C (p<0.01) and in thickness between group B & C (p<0.05). Conclusion: The presence or absence, positional change and variation in gross dimension of the thyroid isthmus were evident in humans. The morphological difference was found with increasing age but not with sex.

Isthmus of Thyroid gland is constricted part which connects the Thyroid lobes in the median plane. The isthmus vary greatly & sometimes may be absent. 1 Agenesis of the thyroid isthmus can also be defined as the ABSTRACT Background: The knowledge of various morphological & developmental anomalies of thyroid gland will help the surgeons in better planning of safe & effective surgery. Considering these facts we studied the variations of thyroid gland. Methods: The material for the present study was collected from the department of forensic medicine, MMC & RI, Mysore, which includes 56 male and 33 female adult postmortem cadavers aged between 18 to 80 years. A dissection was carried out to expose thyroid glands & variations were observed in the morphology of thyroid gland. Results: 1) 9% of specimens had agenesis of isthmus. 2) 46% of specimens had pyramidal lobe. 3) 41% of specimens had levator glanduli thyroidae. 4) 2.24 % of specimens had accessory thyroid tissue. Conclusion: This study highlights the various morphological anomalies of the thyroid gland which forms cornerstone to safe & effective surgery.
