Abstract

Purposes: To investigate the morphology of the crista galli, the prevalence of its pneumatization, and its relationship with adjacent structures. Material and Methods: A cross-sectional descriptive study was conducted on 120 patients who underwent consultation, treatment, and were indicated for CT scans of the paranasal sinuses at the University Medical Center Ho Chi Minh City from 2024 to 2025. Results: There were 120 subjects included in the study, the teardrop type was the most common morphology of the crista galli 51,7%, followed by the tubular type at 45,8% and the ossified type for 2,5%. Females were predominant in the teardrop (58,1%) and tubular (63,6%) types compared to males; 100% of the ossified cases were female. The prevalence of crista galli pneumatization was 29,2%, of which 65,7% drained into the frontal sinus and 34,3% drained to the ethmoid air cells. Conclusion: The teardrop type is the most common morphology, with females predominating in all three types compared to males. There was no statistically significant difference between crista galli morphology and gender. Pneumatized crista galli predominantly drains into the frontal sinus. The association of pneumatized crista galli with both the frontal sinus and the ethmoid air cells was statistically significant.
