Risk of Subsequent Migraines in Facial Fracture Patients: A Population-Based Cohort Study
Abstract
Background: Limited studies have discussed the association between facial fractures and subsequent migraines. In this study, we examined this association and the effect of facial fracture and surgery on the development of migraines. Methods: We selected 5034 patients with facial fractures and a matched cohort of 20,136 patients without facial fractures or facial-associated surgery with a history of migraine from the National Health Insurance database. Risk factors included age, gender, occupation (white-collar, blue-collar, and others), and comorbidities. Patients were frequency matched by age, gender, and index year. The incidence of migraine and the association between migraine development and facial surgery were identified by facial fracture location stratification. Results: The incidence of migraines in the facial fracture cohort was 1.37-fold higher when compared with the comparison cohort (6.47 vs. 4.73 per 1000 person-years). There was a 1.31-fold risk of migraines in the adjusted hazard model and a 1.30-fold risk of migraines in the subdistribution hazard model (95% confidence interval [CI], 1.12-1.52 and 1.12-1.51, respectively). Malar/maxillary and nasal fractures showed 1.48- and 1.29-fold risks of migraines in the adjusted hazard model and subdistribution hazard model (95% CI, 1.16-1.89 and 1.05-1.59, respectively). There were no significant differences in migraine occurrence among patients who underwent surgery. Conclusions: Our findings indicated that…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 20,136 participants or records.
