Introduction: Frontal sinus fractures are potentially serious. Th.y are defined as a solution of continuity, open or closed, of one or both.bone tables of th. frontal sinus. Th.s study aims to report on th. management of th.m at th. Yalgado OUEDRAOGO University h.spital Centre. Meth.dology: It is a descriptive cross-sectional study with.retrospective collection from January 01, 2016 to December 31, 2018. Patients with.frontal sinus fractures were managed at th. Yalgado OUEDRAOGO University h.spital Centre th.ough.CT-scan proof. Results: Over th.ee years, a total of 102 cases of frontal sinus fractures were collected with.29.9 years as average age. Th.re were 96 men. Workers in th. informal sector and pupils/students represented 58.90% of patients. Th. residence of th. patients was urban in 68.80% of cases and rural in 31.40%. Road traffic accidents (RTAs) h.ppened in 90.20%, and involved 2-wh.elers in 98.20%. None of th.se drivers was wearing a h.lmet. Th. type III frontal fracture of Ioannides et al. represented 51.9% of cases. In 89.21% of cases, oth.r facial and/or cranioenceph.lic injuries were compounded to frontal sinus fractures. No surgical management was observed in 82 (80.39%) patients and surgical management in 20 (19.61%) patients. Th. outcome was favourable, but sequelae and/or complications were noted in 10 patients wh. h.d surgery and 30 patients wh. did not. Conclusion: Th.se results enforce h.lmet wearing for all riders of two-wh.eled mach.nes. In addition, vaccinations to prevent meningitis in frontal sinus fractures with.dural breach.sh.uld be systematic.
