Abstract
Background and Aim: Development of hypothyroidism following hemithyroidectomy, although under-appreciated, its detection prevents further complications and saves the retained lobe of thyroid to a great extent.
Methods: A study was conducted amongst 480 patients who had undergone Hemithyroidectomy in the Department of Experimental /Endocrine Surgery of SCB Medical College & Hospital, Cuttack (Odisha) from 2012 to 2018 to determine the incidence of Hypothyroidism.
Results: It was observed that 15% of cases developed overt and 5.4% developed sub-clinical hypothyroidism following Hemi-thyroidectomy. Maximum number of cases were diagnosed within 18 weeks of surgery.
Conclusion: Incidence of Hypothyroidism following Hemithyroidectomy in our study is quite high amounting to 20.4% which includes both sub-clinical as well as overt cases. Overt cases being treated with Levothyroxine, subclinical cases had been followed up carefully.
