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

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