Results Symptomatic and cosmetic scores were significantly improved (pre-RFA vs. One-way analysis of variance was applied to compare volume reduction rate (VRR) at 3, 6, and 12 months. Multiple linear regression analysis was applied to determine significant factors to predict the efficacy of RFA.

Statistical Analysis Paired t test was applied to compare laboratory findings before and after RFA procedure. RFA-related complications (hematoma, voice change, hypothyroidism, and hyperthyroidism) were assessed. Symptomatic score with 10-cm visual scale, cosmetic score with four-point scale, and US findings (nodule diameter, volume, composition and vascularity) were compared before and after RFA procedures. Materials and Methods Eight-nine benign thyroid nodules of 63 patients were enrolled, who were treated by percutaneous ultrasound (US)-guided RFA from 2017 to 2020, and had following US examinations during 12 months after RFA procedure.

This study aimed to investigate the efficacy and complications of RFA to treat symptomatic benign thyroid nodules in United Arab Emirates. Objectives Radio frequency ablation (RFA) to treat thyroid nodules is well known as one of alternative therapeutic modalities.
