Determination of Radiological Variations of Crista Galli in Humans

A cross sectional study that was ethically approved and conducted at the Rivers State University Teaching Hospital and Intercontinental Diagnostic Center in Rivers State. The crista galli is a bony prominence within the anterior cranial fossa that exhibits significant anatomical variations that have clinical implications for neurosurgical and endoscopic sinus procedures. This review examines the diverse morphological presentations of the crista galli, including variations in size, shape, position, and pneumatization. Radiological imaging techniques, particularly computed tomography (CT), have provided valuable insights into these variations. Understanding these anatomical nuances is essential for surgeons to navigate the complex anatomy of the anterior skull base and minimize potential complications. The computed tomography images of 251 adults were evaluated for the types of Crista galli, based on its relation to the cribiform plate, and the Crista galli was also accessed for the presence of pneumatization. The generated data were analyzed using SPSS; the frequencies of the variants were presented in percentages. The K test was used to evaluate the differences in types of Crista galli, and the independent t test was used to evaluate sex differences. The type II Crista galli was the most common kind in both males and females, accounting for 71.2% and 72.3% of cases, respectively. Additionally, the data demonstrated a statistically significant association between the gender and the of crista galli as (P=0.812). However, the Statistical Significance of the P-value 0.135 indicates that there is a statistically significant difference in the Crista Galli types.
