Volume maximised glycerol rhizolysis for trigeminal neuralgia: a single centre analysis of outcomes.

Volume-maximised glycerol injection is safe and effective when compared to literature-reported outcomes post-standard volume glycerol injections. The duration of pain freedom achieved exceeds most literature-reported studies, with hypoaesthesia outcomes being comparable with previous studies. Pain freedom outcomes are more favourable in those with post-procedure hypoaesthesia.
