A Exposure of lateral edge of thyroid cartilage plate.B After the moderate outwards traction and lysis of the surrounding tissue, the parglottic space was exposed. C Enter the pharyngeal cavity from the paraglottic space and remove the tumour under direct vision. D Remove the tumour along the safe boundary of the tumour. E the mucosa of the posterior wall of the hypopharynx is sutured up and down to widen the pharyngeal cavity.F Suture the pharyngeal mucosa and close the pharyngeal cavity
2. Repair
For stage T1 and T2 lesions, the pharyngeal cavity can mostly be closed with local mucosal pulling sutures after tumour resection. For stage T3 and T4 lesions, such as the tumour of the lateral wall of the piriform sinus invading the posterior wall of the hypopharynx or the tumour invading the entrance of the oesophagus, the defect of the lateral wall of the pharynx is so large that it is difficult to pull and suture directly after tumour resection. The most common method we use to repair the pharyngeal cavity is pedicled pectoralis major myocutaneous flap (Such as Video2). In addition, after the pharyngeal cavity was closed, the ipsilateral uninvolved thyroid lobe was lifted and fixed on the lateral side of the pharyngeal suture to strengthen the pharyngeal wall and reduce the incidence of pharyngeal fistula.
