The Bipolar Coagulation Forceps Prevented Salivary Fistula in Patients with Parotidectomy


 Background: Salivary fistula is a relatively common complication in patients with parotidectomy. The purpose of this study was to investigate the effect of bipolar coagulation forceps in salivary fistulas.Method and Material: From March 2015 to June 2020, 177 patients for management of parotidectomy were recruit from the Department of Oral and Maxillofacial Surgery at the Second Xiangya Hospital, Central South University. The patients were divided into experimental group and control group according to application of bipolar coagulation forceps or suture, respectively.Results: The draining output of experimental group was dramatically decreased compared to control group (p = 0.04). The duration of pressure dressing application in experimental group was significantly increased compared to control group (p = 0.0003). Moreover, the incidence of salivary fistula in experimental group (9.8%, 8/82) was notably lower than that in control group (34.7%, 33/95) (p < 0.0001). In logistic regression model for salivary fistula development, both of bipolar coagulation forceps (p = 0.0026) and draining output (p = 0.0186) associated with salivary fistula.Conclusion: Our findings indicated that bipolar coagulation forceps decreased the incidence of salivary fistula in parotidectomy patients. The bipolar coagulation forceps is a safe, effective, and convenient method to prevent salivary fistulas in parotidectomy patients.
