PURPOSE: The aims of this work were to assess the feasibility and efficacy of CT-guided microwave ablation (MWA) in the treatment of @entity10545 ( @entity10545 ). MATERIALS AND METHODS: Thirteen consecutive @entity1 (range 11-31  years old) presenting with OO were prospectively included and treated by CT-guided MWA. Power and duration of MWA were both recorded. The @entity1 's @entity158 was assessed using a numeric @entity158 rating scale (NRS), and side effects were recorded during procedures, after 1  day, 7  days and 1  month. The nidus vascularization and the volume of @entity39 induced by MWA were assessed using contrast-enhanced MRI. Success was defined as the complete relief of the @entity1 's @entity158 1  month after the first procedure, associated with @entity39 of the nidus on follow-up MRI. RESULTS: The success rate was up to 92.3% (12/13). At 1  day, 7  days and 1  month, the median NRSs were respectively 5 [interquartile range (IQR) 2-5], 0 (IQR 0-1) and 0 (IQR 0-0). Side effects observed were one partial and self-resolving lesion of a sensory branch of the radial nerve and two @entity272 . The median power of the MWA used was 60  W (IQR 50-60) with a 1.5-min duration (IQR 1-2), leading to MWA-induced @entity39 measuring on average 23   *   15   *   16  mm. CONCLUSION: CT-guided MWA of OO has a success rate that appears to be almost similar to that of laser or radiofrequency ablation, but care must be taken to prevent nerve or @entity272 .
