Background And ObjectivesTobacco use is known to affect incidence and postoperative outcome for several neurosurgical disorders, but its relationship to trigeminal neuralgia (TN) is not known. We sought to identify unique population characteristics that correlate with tobacco use in a cohort of patients with TN who underwent microvascular decompression (MVD), including effect on long-term postoperative outcome.MethodsData about 171 patients with classic TN treated with MVD were obtained from a prospectively maintained registry. Patients were classified as smokers or nonsmokers based on the use of tobacco within the 6 months before surgery. Analysis of clinical characteristics and postoperative outcome was performed.ResultsCompared with nonsmokers with TN, MVD patients using tobacco were significantly younger (53 vs 62 years, P < .01) and less likely to report pain in a single distribution of the trigeminal nerve (36% vs 65%, P < .01). There was no difference between smokers and nonsmokers in the presence of some degree of continuous pain, severity of neurovascular compression, sex, race, obesity, pain duration before presentation, immediate postoperative outcome, length of stay, or postoperative complication profile. Among 128 patients followed for at least 6 months, smokers were significantly less likely to be pain-free off medications at the last follow-up (36% vs 57%, P < .05).ConclusionIn patients undergoing MVD for TN, smoking is associated with younger age of TN onset, more widespread facial pain, and worse long-term postoperative outcome after MVD. These features suggest that TN in smokers may represent a more severe disease form compared with TN in nonsmokers with different responses to treatment.Copyright © Congress of Neurological Surgeons 2024.
