Abstract: Objective　 To evaluate the effect of partial superficial parotidectomy on benign parotid tumor of superficial lobe. Methods The literatures were retrieved with computers about partial superficial parotidectomy for benign parotid tumor of superficial lobe from MEDLINE, EMbase, Cochrane Library, CNKI, CMCI, VIP, CBM, WANGFANG database. The data extraction and quality assessment were analyzed by two reviewers independently using software RevMan5.1. Results 24 studies were included, there were 1111 cases in PSP group and 1095 cases in SP group. Meta analysis showed: PSP surgical procedures can reduce the operation time (MD = -28.55,95% CI :10.43-14 .78; P <0.00001), and reduce the incidence of temporary facial paralysis, Frey's syndrome, salivary fistula [(OR = 0.27,95% CI :0.20-0 .35; P <0.00001), (OR = 0.20,95% CI :0.13-0 .32; P <0.00001), (OR = 0.29,95% CI :0.15-0 .55; P = 0.0002)], and the difference was statistically significant. It can also reduce the incidence of permanent facial paralysis (OR = 0.34,95% CI :0.11-1 .05; P = 0.06), but the difference was not statistically significant. In terms of the recurrence rate, there was no statistically significant difference between the two groups (OR = 1.23,95% CI :0.54-2 .81; P = 0.62). Conclusion The operative time of PSP is shorter. PSP is effective in shortening the operation time, reducing the incidence of postoperative complications and its curative effect is reliable, thus it can be used as the treatment of choice for benign superficial lobe of parotid.
