Is there evidence or bias that older adults with trigeminal neuralgia who have become resistant to medications cannot undergo microvascular decompression? 476 people were divided into two groups: 117 in group 1 approximately 65 years old and 359 in group 2 less than 65 years old. CONCLUSION: There were no deaths and no significant differences in dangerous complications of the procedure between the two groups. Microvascular decompression is a less dangerous procedure for people older than 65 years.
