Background Total thyroidectomy is a common procedure, we wish to examine the effects of utilizing a harmonic scalpel with traditional procedures on parathyroid hormone levels. Patients and methods 100 patients who underwent total thyroidectomy at the Department of General Surgery, were enrolled in this prospective randomized study, were randomly allocated into two equal groups: Group I: total thyroidectomy using a harmonic scalpel (HS) and Group II: total thyroidectomy using conventional technique. Results There is a significant association between the technique of surgery and the decrease in Postoperative PTH, Mean Difference, Pre and Postoperative and the change Pre PTH (p-value <0.001). Conclusion The postoperative serum level of parathyroid hormone declined significantly after thyroidectomy if the conventional method was used. Using HS during thyroidectomy is safe and effective with low rates of hypoparathyroidism.
