Dorsal root entry zone lesions were made to include the involved dermatomes added one half of the dermatomes above and below the painful areas. Four patient noticed good pain relief with follow up period ranging from 6 to 24 months. Patient whose lesions were performed using a CO2 laser mas suffered no complicated deficit.
