Sponsor's own description
With the continuous development of microsurgery, supporting laryngoscopy acoustic polyp removal has become a very mature clinical operation. The operation has small trauma, short operation time, fast turnover and needing to wake up as soon as possible, but the supporting laryngoscopy has great stimulation to the throat and great hemodynamic fluctuations. This study aims to evaluate the efficacy of ultrasound guided superior laryngeal nerve block as an adjuvant to general anesthesia during vocal cord polypectomy by laryngoscopy.
