Objective To compare the effects of partial superficial parotidectomy (PSP) and superficial parotidectomy (SP) on benign tumor of parotid gland in superficial lobe. Methods A total of 84 patients with benign tumors of parotid gland in superficial lobe in our hospital were selected as the research subjects, and they were randomly divided into PSP group (observation group, n=42) and SP group (control group, n=42). The indicators related to operation (intraoperative blood loss, operation time, branch numbers of facial nerves and length of incision) and postoperative complications [gustatory sweating syndrome (Frey syndrome), temporary facial paralysis, salivary fistula, earlobe numbness] in the two groups were recorded, and the negative emotions of appearance [Body image concerns questionnaire (BICI)] and states of body image [Body image scale (BIS)] in the two groups were compared before and 6 months after operation. Results The intraoperative blood loss, operation time, branchnumbers of facial nerves, length of incision and incidence of postoperative complications in the observation group were all lower than those in the control group(P<0.05). 6 months after operation, the scores of BICI and BIS in the two groups were all higher than those before operation (P<0.05), and the scores in the control group were higher than those in the observation group(P<0.05). Conclusion Compared with SP, PSP, whose effect is better for patients with benign tumor of parotid gland in superficial lobe, can optimize the indicators related to operation, reduce the risks of postoperative complications, alleviate the negative emotions of appearance, improve their states of body image, and it also has positive significance to improve patients' quality of life.
