Interventions

PROCEDUREUS-guided thyroid cartilage plane block (group TCPB)

Participants in the (group TCPB) will receive US-guided thyroid cartilage plane block. Ultrasound-guided bilateral Thyroid Cartilage Plane Block is performed using the thyroid cartilage plate as an anatomical landmark. 3ml of 2% lidocaine is injected on the surface of the thyroid cartilage plate. Subsequently, perform fiberoptic bronchoscope-guided oropharyngeal, subglottic, and tracheal surface anesthesia. After completing surface anesthesia, perform fiberoptic bronchoscope-guided tracheal intubation, securing it properly.

PROCEDUREUS-guided traditional superior laryngeal nerve block (group traditional SLNB)

Participants in the (group traditional SLNB) will receive US-guided traditional superior laryngeal nerve block. Traditional Superior Laryngeal Nerve Block is performed using the thyrohyoid muscle and thyrohyoid membrane as an anatomical landmark. The thyroid cartilage and the greater horn of hyoid bone are hyperechoic signals on sonography. 3ml of 2% lidocaine is injected above the thyrohyoid membrane next to the superior laryngeal artery between two hyperechoic structures. Subsequently, perform fiberoptic bronchoscope-guided oropharyngeal, subglottic, and tracheal surface anesthesia. After completing surface anesthesia, perform fiberoptic bronchoscope-guided tracheal intubation, securing it properly.
