Management of Recurrent Glossopharyngeal Neuralgia Following Microvascular Decompression Surgery

MVD is considered the first line of treatment in drug-resistant idiopathic GPN. Thorough exploration of REZ for small arteries and veins is mandatory to prevent recurrence. Vascular compression can occur at the cisternal portion or at the REZ. In recurrent cases, splitting of the glossopharyngeal nerve rootlets adds to the good outcome.
