Effectiveness of Radiofrequency Ablation Therapy in Osteoid Osteoma: Our 5 Years Experience
Journal Title: Bezmiâlem Science - Year 2021, Vol 9, Issue 2
Abstract
Objective: To evaluate the results of treatment with computed tomography (CT) guided percutaneous radiofrequency ablation (RFA) for osteoid osteomas (OO) and to evaluate imaging findings. Methods: Sixty-three patients (18 female, 45 male) with OO included. Patients were diagnosed by clinic and radiologic findings. Mean age was 18.2 (4-51). Ablation was performed under sedoanalgesia and local anestesia in CT room. Eleven-fifteen gauge coaxial needle was introduced to nidus and 17 gauge RF probe was placed to nidus trough coaxial system. Ablation duration was 6 minutes. Results: Mean nidus size was measured as 8.3 mm (2-16 mm). As a result of statistical analysis, as the size of the nidus increased, the chance of detecting nidus increased on both plain radiography and magnetic resonance imaging (p<0.001). In 63 patients who underwent RFA, only 3 patients were operated for relapse. One patient received RFA for the second time because of recurrence. Our primary success rate in the treatment of osteoid osteoma was 93.6% (59/63) and overall success rate was 95.4%. Conclusion: RFA is a minimally invasive, safe and effective treatment option and has many advantages in the treatment of osteoid osteoma. RFA should be the method of choice for the treatment of osteoid osteoma.
