超声引导下微波消融在腮腺良性肿瘤中的应用价值研究

目的 探讨超声引导下经皮微波消融治疗腮腺良性肿瘤的临床疗效。方法 本研究回顾性纳入了2020年1月至2023年3月期间于我院接受超声引导下微波消融术治疗的18例腮腺良性肿瘤患者。通过随访过程中肿瘤最大直径、体积、体积缩小率及美容评分的变化评估治疗效果。同时评估与微波消融相关的并发症。结果 共纳入了18名患者（男性11例,女性7例,平均年龄63.2±17.2岁）。微波消融术后1个月、3个月、6个月和12个月的平均体积缩小率分别达到0.37%±0.12%、0.57%±0.10 %、0.81%±0.09 %、0.90%±0.07%。随访结束时,平均美容评分也从3.28±0.67降低至1.75±0.93（P<0.001）,亚组分析显示,初始最大直径较小的肿瘤术后美容评分降低更快。结论 超声引导下治疗腮腺良性肿瘤具有良好的临床疗效,对患者进行早期干预可以获得更好的美容效果。

Clinical value of ultrasound-guided microwave ablation in benign parotid tumors

Objectives To study the clinical value of ultrasound-guided percutaneous microwave ablation (MWA) in benign parotid tumors. Methods Eighteen patients with benign parotid tumors who were treated with ultrasound-guided MWA between January 2020 to March 2023 were included in this retrospective study. Changes in tumor longest diameter, tumor volume, volume reduction rate(VRR), and cosmetic score(CS) were evaluated during the follow-up time. Evaluate complications associated with MWA at the same time. Result A total of 18 patients (11 males and 7 females, median age 63.2±17.2) were included in the study. The mean VRR of 1, 3, 6, and 12 months after MWA had reached 0.37%±0.12%, 0.57%±0.10 %, 0.81%±0.09 % and 0.90%±0.07%, respectively. Mean CS also changed from 3.28±0.67 to 1.75±0.93 (P＜0.001) at the end of follow-up time. Subgroup analysis showed that those tumors with smaller initial longest diameters had a faster CS reduction rate. Conclusion The results of this study demonstrated that ultrasound-guided percutaneous MWA has good clinical effects, and early intervention for patients can achieve better cosmetic results.
