All patients had failed extensive medical trials prior to PRGR. Long-term (median follow-up, 36 months) complete pain relief (no further medication) was achieved in 29 (59%) of 49 evaluable patients. Eight patients (16%) had satisfactory pain control but required occasional medication. Twelve patients (25%) had initial unsatisfactory results with inadequate pain relief; nine underwent alternative surgical procedures. Sixteen patients (30%) subsequently required repeat glycerol rhizotomies to reachieve pain control. Twenty-seven patients (60% of 45 patients evaluated for this finding) retained normal trigeminal sensation after injection. Major trigeminal sensory loss developed in a single patient who had four glycerol rhizotomies over a 25-month interval. No patient developed deafferentation pain. We believe that PRGR is a low-morbidity, effective, and repeatable surgical procedure for the management of trigeminal neuralgia in the setting of multiple sclerosis.<\/jats:p>","DOI":"10.1017\/s0317167100049076","type":"journal-article","created":{"date-parts":[[2016,2,17]],"date-time":"2016-02-17T09:29:08Z","timestamp":1455701348000},"page":"137-140","source":"Crossref","is-referenced-by-count":59,"title":["Long-Term Results after Glycerol Rhizotomy for Multiple Sclerosis-Related Trigeminal Neuralgia"],"prefix":"10.1017","volume":"21","author":[{"given":"Douglas","family":"Kondziolka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.
