Objectives: To determine frequency of Transient & permanent hypocalcemia after Thyroid Surgery for Malignant thyroid disease. Study Design: Observational study. Setting: Public & Private Sector Hospitals of Hyderabad. Period: December 2008 to April 2016. Materials and Methods: All patients of Thyroid pathology who fulfilled the inclusion criteria were admitted in the ward. They were evaluated preoperatively & surgery was performed. Postoperatively patients were assessed clinically & biochemically for Hypocalcaemia. Patient's data was recorded & analyzed for variables like age, sex, diagnosis of thyroid disease on FNAC, Type of thyroid Malignancy, type of thyroid surgery, Transient & permanent hypocalcemia in relation to type of type of thyroid surgery performed & the hospital stay. Results: Total 254 patients were operated for different thyroid pathologies. It includes 91(35.82%) male & and 163 (64.17%) female patients making ratio of 1: 1.79. Mean age was 37.29 ±7.4 years. Amongst them 33 patients were diagnosed as Malignant Thyroid diseases. Most common type of thyroid malignancy detected was papillary carcinoma in 48.48% patients followed by follicular carcinoma in 42.42% patients. Most common surgical procedures performed includes completion thyroidectomy in 57.57% patients with 01(3.03%) of them underwent cervical neck dissection followed by total thyroidectomy in 36.36% patients with 02(6.06%) of them underwent cervical neck dissection. Postoperative hypocalcemia was noted in 45.45% patients with 36.36% patients developed hypocalcemia within 24 hours of operation, 6.06% within 24 to 48 hours & 3.03% patients after 48 hours of surgery. Transient hypocalcemia was noticed in 13/33 (39.39%) cases & permanent hypocalcemia in 02/33(6.06%) patients. Mean hospital stay was 4.13± 0.32 days. Conclusion: Hypocalcaemia was noted in 15(45.45%) patients operated for thyroid Malignancy. Revision surgery & cervical lymph node dissection were noted as risk factors. [ABSTRACT FROM AUTHOR]
