They are defined as a solution of continuity, open or closed, of one or both bone tables of the frontal sinus. This study aims to report on the management of them at the Yalgado OUEDRAOGO University Hospital Centre. Methodology: 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 the Yalgado OUEDRAOGO University Hospital Centre through CT-scan proof. Results: Over three years, a total of 102 cases of frontal sinus fractures were collected with 29.9 years as average age. There were 96 men. Workers in the informal sector and pupils/students represented 58.90% of patients. The residence of the patients was urban in 68.80% of cases and rural in 31.40%. Road traffic accidents (RTAs) happened in 90.20%, and involved 2-wheelers in 98.20%. None of these drivers was wearing a helmet. The type III frontal fracture of Ioannides et al. represented 51.9% of cases. In 89.21% of cases, other facial and/or cranioencephalic 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. The outcome was favourable, but sequelae and/or complications were noted in 10 patients who had surgery and 30 patients who did not. Conclusion: These results enforce helmet wearing for all riders of two-wheeled machines. In addition, vaccinations to prevent meningitis in frontal sinus fractures with dural breach should be systematic.展开更多

But it is poorly described in literature. The clinical significance of this anatomic variant still remains unclear. The purpose of this study was to clarify the anatomy, classification of ISSC and its clinical significance in Chinese subjects. Methods We prospectively identified ISSC in 200 consecutive subjects who had undergone computed tomography （CT） scans： 120 without frontal sinusitis （group 1 ） and 80 with frontal sinusitis （group 2）. The ISSC was classified into two types： Type ⅠISSC communicated with frontal sinuses, type Ⅱ ISSC communicated with frontal recess. The patients of frontal sinusitis had undergone functional endoscopic sinus surgery with the assistance of the classification of ISSC. Statistical analysis was performed to correlate the ISSC and its type to the presence of frontal sinusitis. Results The ISSC was obvious when reviewing the coronal and axial CT scans. Of the 200 CT scans reviewed, ISSC were present in 90 （45%）. Of the 120 scans in group 1, ISSC were present in 49 （41%）, among which type ⅠISSC was in 22 （18%） and type Ⅱ was in 27 （23%）. Of the 80 scans in group 2, ISSC was present in 41 （51%）, among which type Ⅰ ISSC was in 16 （20%） and typeⅡwas in 25 （31%）. There were no statistically significant differences about the frequency distribution of total ISSC, type Ⅰ and Ⅱ ISSC between group 1 and group 2. Conclusions The prevalence of ISSC was very high in Chinese patients. The classification of ISSC was helpful for surgeon to operate according to whether it communicated with frontal sinus or frontal recess. The type Ⅱ ISSC could be relatively easily removed from frontal recess.展开更多
