[Application of modified Z-shaped cosmetic incision in parotid benign tumor resection]

Objective:To explore the safety and aesthetic effect of modified Z-shaped cosmetic incision in parotid benign tumor resection. Methods:A prospective study was conducted. A total of 44 patients with benign parotid tumor resection were randomly divided into experimental group（n=22） and control group（n=22）. The experimental group underwent modified Z-shaped cosmetic incision, while the control group underwent the traditional S-shaped incision. The surgical duration, hospital stay, complications and maxillofacial aesthetics were compared between the two groups. Results:There was no significant difference in gender, age, surgical method, pathological type between the experimental group and the control group（P>0.05）. The maxillofacial aesthetics and surgical duration of the two groups was statistically significant（P<0.05）, while there was no statistically significant difference in terms of hospitalization days, surgical complications and Vancouver scar scale score （P>0.05）. Conclusion:The modified Z-shaped cosmetic incision has a better effect on improving the maxillofacial aesthetics after benign parotid tumor resection, and compared with the traditional S-shaped incision, the safety is consistent, so it is worthy of clinical promotion and application.
