Key steps of the operation. a Exposure of the posterior margin of the thyroid cartilage plate. b Pulling the thyroid cartilage plate outward to expose the paraglottic space. c Separating from the paraglottic space and entering the pharyngeal cavity, resecting the tumor under direct vision. d Assessing the tumor margin. e The aryepiglottic fold is complete after tumor resection, and the pharyngeal cavity is widened by several stitches in the upper and lower mucosa of the posterior pharyngeal wall. f Closing the pharyngeal cavity with the pharyngeal mucosa suture
