The follow-up period ranged from 7 to 52 months postoperatively. It was noted that 84% of the patients had immediate relief of pain. The overall recurrence rate was 29%. Based on Kaplan-Meier survival curves, the overall half-life (T\u00bd<\/jats:sub>) of this procedure was 16 months. Although none of the patients developed anesthesia dolorosa or corneal ulceration, one group of patients developed either a clinical or subclinical persistent \u201cminimal hypesthesia.\u201d In these there was a statistically significant difference in the T\u00bd<\/jats:sub> associated with this procedure (p = 0.01). This finding suggests that, contrary to the general belief, persistent hypesthesia after glycerol rhizolysis is a negative indicator of long-term success.<\/jats:p>","DOI":"10.3171\/jns.1990.72.1.0055","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T18:19:03Z","timestamp":1242238743000},"page":"55-58","source":"Crossref","is-referenced-by-count":28,"title":["Relation of hypesthesia to the outcome of glycerol rhizolysis for trigeminal neuralgia"],"prefix":"10.3171","volume":"72","author":[{"given":"K.
