We report the radio-frequency ablation technique applied on an osteoid osteoma under CT guide and review other new methods of treatment for the osteoid osteoma. An 18-year-old boy with an osteoid osteoma at the left proximal tibia, which was visible at plain film and MRI. He was treated by the percutaneous radio-frequency ablation technique under CT guide after a needle biopsy. He is free from any symptom and able to do daily activities. So, we proposed that the percutaneous radio-frequency ablation technique under CT guide is the effective and safe treatment method for an osteoid osteoma.

Stellate ganglion block is frequently effective on the pain of head and upper extremities. However, if the degree and duration of pain relief does not increase with repeated blocks, we may consider the neurolytic procedure on the stellate ganglion. A patient sufferring from the pain in the region of ophthalmic branch of left trigeminal nerve and left eyeball region had been treated with stellate ganglion block. In spite of repeated blocks, the degree and duration of pain relief did not increase. We performed the radiofrequency thermocoagulation of stellate ganglion at the operation room under fluoroscopy. Patient got pain relief immediately after the procedure without any remarkable complication except a mild ptosis, which was shown before the procedure. We may give priority to radiofrequency thermocoagulation for stellate ganglion neurolysis due to its simplicity and safty.
