Microwave ablation (MWA) has emerged as a minimally invasive technique, transforming the therapeutic landscape for benign thyroid nodules (BTN), papillary thyroid microcarcinoma (PTMC), and cervical lymph node metastasis (CLNM). This study aims to present the first experience in Ecuador using MWA.

This study explores the use of radiofrequency ablation (RFA) or related thermal techniques for treating benign thyroid nodules. It highlights clinical outcomes, safety, and effectiveness relevant to both patients and insurance providers. Microwave ablation (MWA) has emerged as a minimally invasive technique, transforming the therapeutic landscape for benign thyroid nodules (BTN), papillary thyroid microcarcinoma (PTMC), and cervical lymph node metastasis (CLNM). This study aims to present the first experience in Ecuador using MWA. We included adults undergoing MWA for BTN, PTMC, and CLNM between September 2022 and April 2023. Descriptive statistics and the Wilcoxon signed-rank test were used to compare some pre- and post-intervention outcomes.
