Morphological study of parathyroid in relation to thyroid gland of Bangladeshi people.

ABSTRACT

The morphological study was done to see the number and location of parathyroid glands in relation to thyroid gland of Bangladeshi people to increase the knowledge regarding variational anatomy in our population. Sixty post mortem tissue block containing thyroid and parathyroids along with surrounding structures were collected from 48 male and 12 female cadavers of different age groups and fixed in 10% formol saline solution. Gross and fine dissections were carried out to study the topographic relationship and number of parathyroid glands in relation to thyroid gland. In the present study, findings were compared with the findings of Western and Bangladeshi researchers. In the present study, the so-called typical number of parathyroid glands that is 2 pairs per person (in relation to thyroid gland) was externally visible only in fifty percent (50%) of cases. According to this study, middle third of posterior border of thyroid gland lodged most of the glands (60-65%).
