Abstract:
Objective:To compare the therapeutic effects of ultrasound-guided radiofrequency ablation (RFA) and surgical resection on salivary gland mixed tumor with diameter ≤3 cm, and to analyze the feasibility and clinical value of RFA in the treatment of salivary gland mixed tumor.Methods:A retrospective study was conducted on 43 patients with salivary gland mixed tumor whose diameter ≤3 cm were treated in the First Affiliated Hospital of Zhengzhou University from March 2020 to March 2022.According to the treatment method, they were divided into an ablation group of 20 cases and a resection group of 23 cases. The complete ablation rate of the ablation group was evaluated, the postoperative absorption of ablation foci in the ablation group was recorded, and the perioperative indexes and the incidence of postoperative complications of the two groups were compared. The long-term prognosis of the two groups was followed up, and the incidence of recurrence, malignant metastasis and appearance recovery were evaluated.Results:In the ablation group, the complete ablation rate was 100.00% (20/20). The lesion volume reduction rates at 1, 3, 6 and 12 months after operation were -(39.60±16.18)%, (8.61±8.10)%, (31.87±14.68)% and (58.64±14.82)%, respectively. The operation time, recovery feeding time, postoperative hospital stay and intraoperative bleeding in the ablation group were less than those in the resection group, and the differences were statistically significant (all P<0.001). Postoperative complications occurred in 2 cases in the ablation group and 9 cases in the resection group. There was significant difference in the total incidence of postoperative complications between the two groups(χ 2=4.768, P=0.029). There was 1 case of recurrence in the ablation group, and no facial depression or protuberance occurred 1 year after operation. There was no recurrence in the resection group, one year after operation, the incidence of facial depression and facial protuberance was 13.04%(3/23) and 0, respectively.There was no malignant metastasis in both groups. Conclusions:Ultrasound-guided RFA is safe and effective in the treatment of mixed tumors of salivary gland with diameter ≤3 cm, and the therapeutic effect is not significantly different from that of surgery. With minimal trauma and good cosmetic effect, it has a great application prospect.
