Introduction: thyroid nodular pathology has a high prevalence in the general population, affecting more than 50 % of healthy people. Most thyroid nodules (TN) are benign and asymptomatic, stable in size and do not require treatment. However, some may grow progressively and without control, leading to pain, hoarseness, dysphagia or dyspnea, as well as alterations of an aesthetic nature that make treatment necessary. Currently, surgery is considered the treatment of choice, and like other surgical interventions requiring general anaesthesia, is not without risks. However, in high-risk surgical patients or those who reject surgery, less invasive alternatives are proposed, such as image-guided thermal ablation procedures, whose objective is to reduce the volume of TN and improve local symptomatology and aesthetics. These include laser ablation (LA) and radiofrequency (RF) ablation, whose benefit/risk balance, ambulatory nature and rapid patient recovery times seem to favour their use.
