Association between Location of Thyroid Nodule and Risk of Malignancy

To identify the anatomical location of thyroid nodule and to find out association of this location with the risk of malignancy. Materials and Methods: The prospective observational study was conducted in Bir Hospital from May 2020 to March 2021. A total of 35 patient with thyroid nodule were included. Ultrasonography of thyroid nodules was done to determine the laterality and polarity. Nodules of size ≥cm were considered and sent for fine needle aspiration cytology. Surgery was done for nodules with malignant features and histopathology was sent. Results: The mean age was found to be 40.6 years. Thyroid nodules were common in female (82.9%) than male (17.1%). Considering laterality, 65.7% nodules were present in right lobe, 31.4% nodules were located in left lobe and 2.9% nodules were located in isthmus. When polarity was taken into consideration upper pole consisted 61.8% and lower pole consisted 31.2% nodules. Conclusion: There was no association between laterality and polarity of nodules with malignancy
