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

To explore the safety and aesthetic effect of modified Z-shaped cosmetic incision in parotid benign tumor resection. A prospective study was conducted. A total of 44 patients with benign parotid tumor resection were randomly divided into experimental group（=22） and control group（=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. There was no significant difference in gender, age, surgical method, pathological type between the experimental group and the control group（>0.05）. The maxillofacial aesthetics and surgical duration of the two groups was statistically significant（<0.05）, while there was no statistically significant difference in terms of hospitalization days, surgical complications and Vancouver scar scale score （>0.05）. 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.
