[Indications for resection of parapharyngeal space tumors by transoral robotic surgery and prevention and treatment of complications].

Abstract

TORS operation is a safe and minimally invasive method in treating parapharyngeal space tumors with appropriate size and location. Postoperative effusion is a common complication after TORS. In case that surgical cavity extends to the deep parapharyngeal space or the lower part of the surgical cavity is beneath the surgical incision, the placement of transnasal negative pressure drainage tube after operation can improve postoperative recovery and reduce the incidence of complications such as effusion and infection.
