Efficacy Analysis of Endoscopic-Assisted Traditional Surgery and Traditional Surgery for Sinonasal Malignant Melanoma

<b>Object:</b> To analyze the effect of traditional surgery and endoscope-assisted traditional surgery on patients with sinonasal malignant melanoma (SMM), and to explore the effective treatment of SMM. <b>Methods:</b> The clinicopathological data and surgical methods of 47 patients with SMM, diagnosed in the Department of Otorhinolaryngology-Head and Neck Surgery at the Third People's Hospital of Yunnan Province from October 2000 to June 2020, were retrospectively analyzed. Among them, 26 cases were treated with traditional surgery, and 21 cases were treated with endoscope-assisted traditional surgery. The 3 and 5 year local recurrence and survival rates were monitored and compared. <b>Results:</b> The 3 year local recurrence rate was compared between the 2 groups: <i>χ</i>² = 5.4558, <i>P</i> = .020 (<i>P</i> < .05), the endoscope-assisted traditional surgery group had a lower 3 year local recurrence rate. The 3 year survival rate was compared between the 2 groups: <i>χ</i>² = 1.0231, <i>P</i> = .312 (<i>P</i> > .05), the difference in 3 year survival was not significant between the 2 groups. The 5 year local recurrence rate was compared between the 2 groups: <i>χ</i>² = 4.4052, <i>P</i> = .036 (<i>P</i> < .05), the endoscope-assisted traditional surgery group had a lower 5 year local recurrence rate. The 5 year survival rate was compared between the 2 groups: <i>χ</i>² = 4.3085, <i>P</i> = .038 (<i>P</i> < .05), the endoscope-assisted traditional surgery group had a higher 5 year survival rate. Therefore, there were significant differences in the local recurrence rates at 3 and 5 years, as well as the 5 year survival rate, between endoscope-assisted traditional surgery and traditional surgery in the treatment of SMM. <b>Conclusion:</b> Endoscope-assisted traditional surgery can remove local lesions of SMM more completely, reduce the local recurrence rate, and improve the 5 year survival rate of patients.
