Abstract: Objective 〖JP2〗To discuss the clinical effects and rationality of partial parotidectomy in the treatment of parotid benign tumors.Methods Among 103 cases of parotid benign tumors,53 cases were treated with partial parotidectomy.The ectomy field was extended 0.51.0 cm from the border line of tumor,with conservation of fascia parotideamasseterica and branch(s) of great auricular nerve; the other 50 patients were treated with conventional superficial parotidectomy.All the patients were followed up for 0.55 years.The differences in the incidence of complications and tumor recurrence between the 2 groups were compared by using Chisquare tests.Results The degree of facial deformity was mild,and the function of parotid was fine after partial parotidectomy.The occurrence rates of Frey syndrome,xerostomia,earlobe numb,facial deformity,temporary facioplegia and salivary fistula in the partial parotidectomy group were significantly (P<0.05) lower than the superficial parotidectomy group.Tumor recurrence was not observed in both groups.Conclusions Partial parotidectomy can completely resect the parotid benign tumors,and significantly decrease the occurrence rate of complications.
