Radiofrequency dissection versus ‘knot tying’ in conventional total thyroidectomy

Abstract

AbstractObjective:To evaluate the safety and effectiveness of radiofrequency dissection in conventional ‘open’ total thyroidectomy.Methods:Thirty-nine patients scheduled for conventional total thyroidectomy were included in a prospective randomised study. Patients were randomly assigned to one of two groups: a radiofrequency dissection method was used in one group, and a knot tying technique was used in the other.Results:Significantly fewer surgical instruments and materials were required for the radiofrequency dissection group than the knot tying group (p < 0.01). There were no significant differences between the two groups in mean operative time, blood loss, post-operative drainage and pain, recurrent palsy, and hypocalcaemia (p > 0.05).Conclusion:Radiofrequency dissection is a safe alternative to the knot tying technique, and enables a significant reduction in the number of surgical instruments required for the operation.
