Özet
Objective: – To reveal differences in morphology of the crista galli (CG) in patients with Chiari malformation type 1 (CMT1) by comparison normal subjects. Methods: – Computed tomography slices of 60 adult CMT1 (gender: 30 females and 30 males, and mean age: 37.20±11.33 y) and 60 adult controls (gender: 30 females and 30 males, and mean age: 42.52±16.08 y) were added to the study. Shape types of CG were identified, and its length (LCG), height (HCG) and width (WCG) were measured. Results: – Chiari malformation type 1 (HCG: 14.73±2.93 mm, WCG: 4.84±1.41 mm, and LCG: 11.33±1.83 mm) had statistically similar measurements to controls (HCG: 14.24±2.41 mm, WCG: 4.63±1.11 mm, and LCG: 11.37±2.21 mm). CMT1s (tear-drop: 35%, tubular: 41.70%, and ossified: 23.30%) had statistically similar CG shape to controls (tear-drop: 36.70%, tubular: 45%, and ossified: 18.30%, P=0.794). CMT1s (Type 1: 28.30%, and Type 2: 71.70%) had statistically similar olfactory fossa depth to controls (Type 1: 21.70%, Type 2: 75%, and Type 3: 3.30%, P=0.275). CG pneumatization was observed in three subjects (5%) of CMT1s and in 5 subjects (8.33%) of controls. Conclusions: – Patients with CMT1 have similar CG size to controls. CMT1 does not correlate with CG shape types and Keros types. Investigations on anatomic structures like CG in the anterior and middle fossae in an effort to identify additional signs specific to CMT1 may be useful for clinicians to understand skull base development of such patients.
