Retrospective Analysis of the Efficacy and Safety of Ultrasound-Guided Radiofrequency Ablation in the Treatment of Papillary Thyroid Microcarcinoma: A Follow-Up Study of Continuous Postoperative Surveillance and Large-Sample Data

<div>Ultrasound images before and after RFA: (a1-a2) the tumor had a volume of 55.83 mm<sup>3</sup> before RFA; (b1-b2) the ablated tissue had a volume of 164.27 mm<sup>3</sup> at 1 month after RFA; (c1-c2) the volume of the ablated tissue decreased to 36.78 mm<sup>3</sup> at 3 months after RFA; (d1-d2) the volume of the ablated tissue decreased to 11.91 mm<sup>3</sup> at 6 months after RFA; and (e) the tumor was completely absorbed at 12 months after RFA.</div>
