Treatment of trigeminal neuralgia by microvascular de decompression

Fifty patients with trigeminal neuralgia were operated upon in Suez Canal University hospital, Al-Sahel Teaching hospital, and Al Azhar University hospital. Micro vascular decompression [MVD] was used in 42 cases, MVD and Rhizotomy in 3 cases, and Rhizotomy only in 3 Cases. The most common etiological factor was arterial loop compression [29 cases]. The superior cerebellar artery was the compressing factor in 24 cases. Thirty five patients had excellent outcome after MVD, 6 good, and 4 had poor outcome. MVD has proved to be an effective method for treatment of Trigeminal neuralgia
