Incidence of Hypoparathyroidism Following Total Thyroidectomy in a Tertiary Care Hospital of Bangladesh.

Total thyroidectomy is a common surgical procedure for MNG and thyroid malignancies with or without lymph node metastasis. Post total thyroidectomy hypoparathyroidism is not so uncommon. Understanding the prevalence of temporary and permanent hypoparathyroidism in post-total thyroidectomy is very important for improving patient outcomes. This prospective observational study was conducted in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2023 to December 2023 where 92 cases were selected purposively who underwent total thyroidectomy for MNG and thyroid malignancy without extra thyroidal extension. The incidence of transient and permanent hypoparathyroidism after total thyroidectomy, demographic variables, and postoperative day of onset of hypocalcemia were analyzed. Data collection was done through patient records and postoperative follow-ups. This study revealed that 23.0% of patients experienced hypoparathyroidism post-operatively. Hypoparathyroidism was most prevalent among patients underwent total thyroidectomy for thyroid malignancy (47.83%) compared to those undergoing total thyroidectomy for benign thyroid disease (17.39%). The majority of hypocalcemia cases (60.87%) occurred on the second postoperative day. Among the 23 cases of postoperative hypoparathyroidism temporary hypoparathyroidism was 69.57% and permanent hypoparathyroidism was 30.43%. After total thyroidectomy Hypoparathyroidism remains a significant complication. Early identification and management of at-risk patients is necessary to reduce the severity of this complication.
