Glossopharyngeal neuralgia is a rare but severe and disabling pain condition often caused by vascular compression of the glossopharyngeal nerve. Treatment is similar to that of trigeminal neuralgia, but some patients may be refractory to both medical and surgical approaches. Here we present a case of refractory glossopharyngeal neuralgia that responded well to onabotulinumtoxinA (BTX-A).
