Microvascular decompression for trigeminal neuralgia: report of outcome in patients over 65 years of age.

Microvascular decompression (MVD) is now recognized as an effective operation for the cure of trigeminal neuralgia (TN), and is far superior to the other surgical procedures utilized in the treatment of TN. TN is common in the elderly, but there is debate concerning MVD in 'elderly' patients. Some clinicians have a policy of not offering patients over a certain age the choice of MVD, yet the recurrence rate is inversely related to the age of the patient. Previous failed procedures and a long period of pain before MVD, also affect the outcome negatively. This study is a retrospective review of the outcome in elderly patients following MVD. Forty-two patients over the age of 65 years are reviewed after undergoing MVD for TN. The results indicate that there was no serious morbidity or mortality that could be ascribed to old age and the length of stay in the hospital was not influenced by the age of the patient. The results are compared with the outcome in a younger age group and the literature on MVD for TN reviewed.
