PURPOSE: To evaluate the usefulness of pressure bandage with kidney-shaped cotton pad in parotidectomy and the relevant factors of parotid salivary fistula occurring after parotidectomy. METHODS: One hundred and ninety-six patients with parotid benign tumor or tumor-like lesions were randomly divided into two groups, 100 cases in the kidney-shaped cotton pad group and 96 cases in the traditional management group. The incidence of postoperative salivary in relation to surgical procedure, main parotid duct ligation, and parotid salivary fistula was analyzed. SPSS13.0 software package was used for Chi-square test. RESULTS: The incidence of parotid salivary fistula in the kidney-shaped cotton pad group was 1%, and the incidence in the traditional management group was 13.54%. The difference between the two groups was significant(P<0.01); Different surgical procedure, ligating the main parotid duct or not, had no effect on salivary fistula(P>0.05). CONCLUSIONS: The kidney-shaped cotton pad pressure bandaging can effectively prevent the occurrence of postoperative salivary fistula and has certain value in clinical application.
