Application of tunnel-type partial superficial parotidectomy in the treatment of benign tumor in the inferior pole of parotid gland
Objective:To observe the efficiency of tunnel-type partial superficial parotidectomy(T-PSP)in the treatment of benign tumor in the inferior pole of parotid gland.Methods:53 patients with benign tumors in the superficial sublobular pole of the parotid gland were included.27 cases were treated with T-PSP(trial group)and 26 with partial superficial parotidectomy(PSP)(control group).The patients were followed up for 1-3 years.The incidence of facial nerve palsy,Frey's syndrome,salivary fistula,periauricu-lar numbness and skin numbness in the parotid area in the 2 groups was compared.Results:Complications such as facial nerve palsy,Frey's syndrome,periauricular numbness and skin numbness in the parotid area were less frequent in the trial group than in the control group(P<0.05),while there was no significant difference in the incidence of salivary fistulae between the 2 groups(P>0.05).No tumor relaps was observed in all cases.Conclusion:T-PSP has fewer postoperative complications in the treatment of benign tumours benign tumor in the inferior pole of parotid gland.
