Introduction: Trigeminal neuralgia is a facial pain syndrome known and characterized by severe, intermittent, electric shocklike, shooting pain in the face for which a number of surgical therapies have been used. To date no ideal, minimally invasive, patient-acceptable treatment is available, hence both patients and specialists face substantial uncertainty when making decisions regarding therapeutic action.Objective: To identify which surgical treatment for TN offers the best opportunity in terms of cost-effectiveness.Material and method: A study was performed using a decision analysis/cost-effectiveness analysis design considering five surgical alternatives in the management of TN: radiofrequency thermocoagulation, glycerol microcompression, balloon microcompression, radiosurgery, and microvascular decompression. Data were obtained from the literature. A review was carried out of the MEDLINE database from 2000 to 2010 via PubMed Central. Studies were selected that addressed primary trigeminal neuralgia and demonstrated pain relief and reduced mortality and complication rates. In all 196 studies were identified but only 22 (11.22 %) were eligible for the study. The software package used

Conclusiones: ambos procedimientos de ajuste son igualmente eficaces en la detección de problemas de eficiencia, pero el modelo de regresión lineal múltiple, para estimar la estadía esperada, resulta mejor que el de los Grupos de Diagnósticos Relacionados por razones principalmente económicas. Este hecho avala su utilización en países o instituciones de recursos limitados como los propios de países no desarrollados.
