Introduction and Objetive. In the trigeminal neuralgia at the moment don't exist a final treatment because of the different response at the miscellaneous handling, therefore is to the physician a challenge how to improve this entity. Several treatments are proponed in the management of this entity. We evaluated in our study two of this. Minor surgical Techniques are relatively simple in the hands of experienced Medical Specialist in Pain Medicine. We compare Gasserian Ganglion Blockade (GGB) with radiofrequency lesión vs intragaserrian glycerol. Material and Methods. In a retrospective, observational, comparative longitudinal study. We studied a total of 58 patients with trigeminal idiopathic neuralgia who underwent to a Gasserian Ganglion Blockade (GGB). Were divided into 2 groups; patients in Group I (23 patients), with Radiofrequency lesión and Group II (35 patients) with intragasserian glycerol, pain intensity was assessed using VAS, previous to the immediately procedure, each month, 6 to 12 months and 12 to 24 months. We evaluated the incidence and number of the need to performed the procedure again (GGB). The frequency of recurrence and the time interval in which it was evaluated, side and adverse effects are also evaluated. Results. No differences were observed between the two groups epidemiological. The branch trigeminal most affected in the Group I was V2-V3 52%, compared with Group II V2-V3 54.2%. Developments in the relief of pain was conducted by the scale of Visual Analogue Scale (VAS), with statistical analysis performed by Mann-Whitney-U test which was significant in the immediate assessment, with a p:<0.05 resulting Group I with a VAS 0.82, Group II VAS 2.0; a month p<0.06, Group I a VAS 1.13 and Group II VAS 2.16; and the period of 1-6 months p>0.01, Group I with VAS 0.82 and Group II a VAS 2.22; at 6-12 months in Group I with a VAS 1.34 and Group II VAS 1.86 for 12-24 months Group I VAS 1.34 and Group II VAS1.55, there being no statistical significance in these two periods of monitoring. Relapse was presented to the Group I in a 30.4% for Group II 62.8%, p:>0.01. Relapse was presented with an average time for the Group I 8.2 months and Group II 6.4. The Need for reblockade for Group I was 21.7% while for Group II was 54.2%, p<0.01. Conclusions. We concluded in this study that the incidence of recurrence and need for reblockade with technical conventional radiofrequency lesión compared with the technique of 100% intragasserian glycerol is reduced. We propose that the Gasserian Ganglion Blockade with conventional radiofrequency is an effective and prolonged procedure for the management of trigeminal idiopathic neuralgia.
