Abstract

Introduction: Most of the thyroid nodules are benign and fewer than 5% of them are actually malignant.There is always a clinical dilemma when FNAC is benign or inconclusive.The presence of solitary or dominant nodule in thyroid should be investigated to exclude carcinoma.Aim: There is significant prevalence of thyroid micro carcinomas among benign thyroid diseases; this study was done to suggest total thyroidectomy (TT) as the preferred method in suspicious thyroid diseases.Material and methods: This is a hospital based analysis of all thyroid surgeries performed in a thyroid service unit over a period of 4 years between 2006 to 2009.The total number of thyroid surgeries during this period was 277.30 patients had undergone completion thyroidectomy following confirmation after hemi thyroidectomies which were done outside.FNAC was the guiding investigation to surgery in all the remaining 247 patients.Results: In the present study, FNAC was done for 247 patients.Cytopathological analysis showed 132 cases of papillary thyroid cancer, 7 cases of MTC and 2 cases of ATC.Out of 106 FNAC proven benign cases, 90 cases had undergone total thyroidectomy, 51 cases were found malignant in final HPR.The incidence of malignancy was 48 % in overall benign thyroid lesions in which association of malignancy was highest for follicular neoplasm [71%] followed by adenomatous hyperplasia [57%].Conclusions: We found that in certain variant of benign thyroid diseases total thyroidectomy can be performed with very low incidence of complications to prevent the future recurrences and reoperations.
