Osteogenesis imperfecta (OI) is associated with cranial base abnormalities, including distinct radiographic ST shapes. Patterns of ST morphology are relevant in understanding the pathophysiology of the neurocranium. The anterior part is derived from neural crest cells, and the posterior wall cartilage develops under the influence of the notochord. Results: Eighteen OI patients were included, fifteen of whom were diagnosed with OI type 3 (OI3), with eleven (73%) confirmed to have pathogenic variants in FKBP10. Figure 1 provides examples of STs identified in this study. Figure 2 provides statistical findings. Statistical analysis revealed no significant difference in ST shape distribution between OI1 and OI3 subtypes.enRadiographic patternsSella turcica shapeOsteogenesisSouth AfricaCraniofacial assessmentPresentation
