Abstract: BACKGROUND: Thermoablation is an attractive treatment of thyroid nodules for its minimal-invasiveness. It remains unclear whether results and morbidity meet the patients’ expectations. OBJECTIVE: The aim of the presented study is to show data obtained after microwave thyroid ablation from a patients’ perspective. METHODS: Indications and preoperative diagnosis were chosen according to international guidelines. Thermoablation was achieved using a CE certified microwave system. The procedures heeded the published recommendations of the European Federation of Societies for Ultrasound in Medicine and Biology. Follow-up included ultrasound, laboratory parameters and a standardized questionnaire. RESULTS: Thirty patients were enrolled into the study. All patients reported an improvement of complaints following the procedure. Scar formation occurred in 3 cases (10%) with 0.5 ± 1.3 mm length and 0.4 ± 1.0 mm width. No cosmetic, neurological, vocal or pharyngeal complication occurred. Energy required for non-functioning nodules (n= 15, 50%) was 2.56 ± 3.41 kJ/mL, for autonomous adenoma (n= 8, 27%) 0.96 kJ/mL (p< 0.05, t-test). CONCLUSION: The presented data summarize an initial experience in selected patients and resemble excellent patient reported outcome with minimal morbidity. These preliminary data indicate the majority of patients satisfied with the procedure. Further trials will be required to endorse these findings.
