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. Dorsal root entry zone lesions appeared to be a satisfactory treatment for intractable pain in patients, who have failed to respond to more conservative mode of therapy.
