RESUMO
Objective To evaluate the effects of the modified opration of benign tumor in parotid gland on the prevention of Frey syndrome.Methods the Parotid benign tumor resection in 28 cases were selected,according to the different treatment methods were divided into observation group of 12 cases,16 cases of the control group.The modified surgical patients in the observation group,two flap method,preservation,preservation of parotid masseter fascia in the branches of the great auricular nerve and parotid region resection,the control group was treated by routine tumors of the parotid gland and parotid superficial lobectomy or resection.Patients were followed up for 6 months to 1 years,underwent minor test,the incidence of Frey syndrome in 2 cases were recorded,postoperative incidence of Frey syndrome were compared.Results The incidence of Frey syndrome in the observation group was significantly reduced compared with the control group.The difference was statistically significant (χ2 =7.479,P <0.05 ). Conclusion The effects of modified opetation combined with secondry disc method in benign tumor of parotid gland on the prevention of Frey syndrome has obvious advantages comparing with the control.
