— In the material of patients with trigeminal neuralgia treated by retrogasserian glycerol injection at the Karolinska Hospital, 23 cases (8%) were also diagnosed as suffering from disseminated sclerosis. These patients were often on carbamazepine treatment before the procedure, a regimen known to cause severe side effects and increase pre‐existing symptoms in patients with multiple sclerosis. Following glycerol injection, more than 90% became pain‐free within the first 2 months and 82% could discontinue drug therapy. This initial outcome corresponds well to the results in our larger series, but the long‐term results in the group with multiple sclerosis is less satisfactory, with 61% recurrence at follow‐up 8‐79 months following treatment. In total 48% were pain‐free at follow‐up, following reinjections in 8 cases. In spite of less satisfactory long‐term results, more than three‐fourths of the patients wanted another glycerol injection after only low‐dose trial with carbamazepine in case of recurrence.
