Popis: Sore throat, hoarseness, dysphagia, and cough are common laryngopharyngeal discomforts after thyroidectomy. The incidence and severity of laryngopharyngeal symptoms after the use of a flexible reinforced laryngeal mask airway (LMA) were compared with those that occur after the use of a plain endotracheal tube in patients after thyroidectomy. Seventy-six patients scheduled for total thyroidectomy were randomized into a plain endotracheal tube group (group E) or a flexible reinforced LMA group (group L). Total intravenous anesthesia (propofol and remifentanil) was used for maintenance of anesthesia. Hemodynamic variables were recorded during induction of anesthesia. The incidence and severity (100-point numerical rating scales) of laryngopharyngeal symptoms, including sore throat, hoarseness, dysphagia, and cough, were assessed at 1, 24, and 48 h after surgery. All patients were placed successfully with an endotracheal tube or a flexible reinforced LMA. The postoperative incidence and severity of sore throat (25 vs. 33 at 24 h, p = 0.035, 17 vs. 28 at 48 h, p = 0.017; 50 [0–100] vs. 80 [20–100] at 1 h, p = 0.002; 30 [0–80] vs. 50 [0–100] at 24 h, p
