Efficacy and Safety of Thermal Ablation for Indeterminate Thyroid Nodules: A Systematic Review of the Literature and Meta-Analysis

TA may be considered a minimally invasive alternative for ITNs who are not candidates for or decline surgery, demonstrating favorable efficacy and safety. However, study limitations, short follow-up, and residual malignancy risk necessitate careful follow-up, particularly for larger nodules. Advanced TA techniques such as hydrodissection may enhance outcomes by increasing the likelihood of complete ablation. Long-term prospective studies and randomized trials are needed to confirm TA's role in clinical practice.
