The primary outcome of the study was the difference in postoperative sore throat scores between the groups, and the secondary outcome was the difference in the severity of postoperative hoarseness and cough.A designated investigator who was blinded to the group allocation evaluated postoperative sore throat, hoarseness, and cough at 3 and 24 h following surgery.Sore throat was defined as continuous throat pain and estimated using a visual analog scale (VAS) on a 100-mm scale. Postoperative hoarseness and cough were assessed using a numerical rating scale. Postoperative hoarseness was measured as follows: 0 = no hoarseness, 1 = experienced only by the patient, 2 = evident to the evaluator, and 3 = difficult to vocalize
