Abstract: Objective To evaluate the effect of bioabsorbable membrane in prevention of Frey syndrome after parotidectomy.Methods 105 patients who suffering from benign tumor of parotid gland were divided into experimental group and control group randomly.53 cases in experimental group underwent insertion of bioabsorbable membrane after parotidectomy,while 52 cases in control group underwent parotidectomy without bioabsorbable membrane.After operation 6 to12 months,all 105 patients were evaluated for gustatory sweating by both questionnaire and minor starchiodine test.Results Subjective evaluation of Frey syndrome revealed that the incidence rate of experimental group and control group were 3.8％(2/53),28.9％(15/52)respectively(P ＜ 0.05).Objective evaluation of Frey syndrome revealed that the incidence rate of experimental group and control group were 9.4％(5/53),55.8％(29/52)(13/21)respectively(P ＜0.05).Conclusion Insertion of bioabsorbable membrane is an effective method for prevention of Frey's syndrome after parotidectomy.
