BACKGROUND/AIM: Down syndrome (DS) patients often show characteristic changes in the skull, e.g. short cranial base. The synchondroses of the skull base have a significant influence on the shape of the skull. The sphenooccipital synchondrosis (SOS) is the last of the basal synchondroses to ossify. This report is about residual ossification of SOS in an elderly patient with DS.
The 65-year-old DS patient was polytraumatized by a fall. In the course of treatment, a purulent otitis externa on the right side was diagnosed, which had developed as a result of the fracture of the fossa glenoidalis. Computed tomograms of the skull base showed the fracture of the mandibular condyle, glenoid fossa and vestiges of SOS.
The coincidental finding of vestiges of SOS in an elderly patient with DS raises the question of whether cross-sectional skull base images can show differences in the ossification of SOS between DS patients and a normal population.
背景/目的：唐氏综合征（DS）患者的颅骨常表现出特征性改变，例如颅底短。颅骨基底的骺软骨结合对颅骨的形状有重要影响。蝶枕软骨结合（SOS）是最后一个发生骨化的基底骺软骨结合。本报告介绍了一例老年 DS 患者 SOS 残余骨化的病例。
这位 65 岁的 DS 患者因跌倒而多处受伤。在治疗过程中，右侧诊断为化脓性外耳道炎，这是由于关节窝骨折引起的。颅骨底的计算机断层扫描显示下颌骨小头、关节窝和 SOS 的遗迹骨折。
在老年 DS 患者中偶然发现 SOS 的遗迹，这引发了一个问题，即横断面颅骨底图像是否可以显示 DS 患者和正常人群中 SOS 骨化的差异。
