Trigeminal neuralgia (TN) is a disabling syndrome and one of the most painful conditions that are often reported in female patients older than 50 years of age. The treatment generally includes drugs or surgical approaches. Laser Phototherapy -LPT has also been proposed as a safe and effective treatment modality. This work reports a series of patients of the Center of Biophotonics of the Federal University of Bahia (2000-2016) treated with LPT. Following standard anamneses, clinical and imaginologic examination and with the diagnosis of Trigeminal Neuralgia, the patients were set for light treatment. Treatment consisted of three sessions a week during six week. Prior irradiation, the patients were asked to score their pain using a VAS. λ780, λ 790, λ 830nm lasers were used on each session. Most patients were female (74.8%). At the end of the 12 sessions the patients were again examined and score their pain using VAS. No other intervention was carried out during the treatment. The results were statistically analyzed and showed that, the use of lower Energy Density in smaller number of session in younger patients presents higher effectivity on treating the pain on TN patients.
