Role of a two-step suture in the prevention of postoperative transoral salivary fistulas during reconstruction of the oral cavity

Transoral salivary fistulas are one of the most serious postoperative complications after operations for oral cancer, and we propose a new, two-step suture method to avoid them. From January 2005 to September 2017, 240 patients were recruited at the Shanghai Ninth People's Hospital and divided into experimental (n=89) or control (n=151) groups. The experimental group was treated by a two-step suture technique, while the control group had conventional sutures. Statistical differences were assessed using the chi squared and t tests, as appropriate.
