[The clinical efficacy analysis of the surgery of the posterior approach parotid gland region resection preserving retinal ganglion and parotid fascia].

Objective:To explore the clinical efficacy analysis the surgery of the posterior approach parotid gland resection preserving retinal ganglion and parotid fascia for the treatment of benign parotid tumour.Method:One hundred and twelve cases were randomly divided into control group and treatment group. The control group was treated by anterior approach parotid gland region resection preserving retinal ganglion and parotid fascia. The treatment group was treated by posterior approach parotid gland region resection preserving retinal ganglion and parotid fascia. The data of operation time, postoperative local numbness, Frey syndrome, facial paralysis and postoperative recurrence case were analyzed. Result:There was no postoperative recurrence case in both two groups, and there was no significant difference between two the groups in operation time and the percent of facial paralysis（all P>0.05）.However, the percent of postoperative local numbness and Frey syndrome in control group were significantly higher than those in treatment group（all P<0.05）. Conclusion:The treatment group had similar clinical efficacy with the traditional surgical operation. In addition, the operation of treatment group contributed to decreased postoperative complications.
