| Summary: | Introduction: The morphological variations of the thyroid
gland have been reported from different parts of the world. The
variations are due to remnant or non-specific development of the
parts of the thyroid gland. Surgical operation of the thyroid gland
has been the treatment of choice in various thyroid pathologies.
Prior knowledge of the morphological variation is important to
ensure better results from these surgical operations.
Aim: To study the prevalence of morphological variations seen
in the thyroid glands in the upper Assam region of Northeast
India.
Materials and Methods: This was a hospital based cadaveric
study. Total number of Thyroid glands dissected were 80.
The thyroid gland was examined properly for the presence of
pyramidal lobe, levator glandulae thyroideae and complete
absence of isthmus. Statistical analysis was done by SPSS
21.0.
Results: It was found that 17 (21.25%) cadavers did not show an
isthmus. The pyramidal lobe was present in 31(38.75%) cases
and frequently arising from the left side (74.2%) of the isthmus.
Levator glandulae thyroideae was found in 15 (18.75%) of the
thyroid specimens. In all cases, it was extended from the apex
of the pyramidal lobe to the hyoid bone.
Conclusion: Morphological variation of the thyroid gland is very
common hence requires detection prior to any surgery on the
thyroid gland. |
