[Algological treatment of trigeminal neuralgia. Experience of 15 years].

Background: We present the experience in the treatment of trigeminal neuralgia (TN) during 15 years in one institute, evaluating epidemiological variables and clinical presentation, and comparing the results obtained with different treatments available.

Methods: A retrospective, descriptive study was carried out by reviewing cases diagnosed by the Neurology Service, such as TN, and treated by the Pain Medicine and Palliative Care Unit of the Insituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubíran," from January 1, 1998 to December 31, 2003. Age, sex, type of neuralgia, anatomical site affected and intensity of pain were evaluated by means of the Analogue Visual Scale (AVS).
