Postoperative sore throat is a common adverse effect of general anesthesia that is characterized by several signs and symptoms, including laryngitis, tracheitis, hoarseness, and cough. The mucosal injury location varies depending on the device used for airway management, with the type of endotracheal tube and the approach to airway management being the most significant physical factorsWhen performing tracheal intubation using a direct laryngoscope, direct stimulation through the blade may damage the airway tissue. In contrast, when performing tracheal intubation under fiberoptic bronchoscope guidance, injury may occur because the tube’s outer diameter is larger than that of the bronchoscope, thereby causing impingement against the glottisThis study aimed to determine a method for reducing the severity of postoperative sore throat following endotracheal intubation under fiberoptic bronchoscope guidance. To reduce impingement during fiberoptic-guided tracheal intubation, several methods have been suggested
