To investigate the correlation between ligamentous ossification or osteophytes of the cervical spine and ossification of the styloid process and stylohyoid ligament, and to determine any relation between diffuse idiopathic skeletal hyperostosis (DISH) of the thoracic spine and ossification of the styloid process and stylohyoid ligament.
Four patients having cervical spine DISH, an elongated styloid process and/or variable patterns of stylohyoid ligament ossification, and clinical findings compatible with Eagle's syndrome are described. Cervical computed tomography scans of 100 patients who also had lateral radiographs of the thoracic spine were reviewed. Point biserial and Spearman rank correlation analysis, McNemar test, chi-squared test, and Fisher's exact test were used to determine correlation between elongation of the styloid process and/or ossification of the stylohyoid ligament and (1) ligamentous ossification or osteophytes of the cervical spine (the characteristic spinal manifestation of DISH), and/or (2) DISH of the thoracic spine.
(1) Elongation of the styloid process and variable patterns of ossification of the proximal, middle, and distal parts of the stylohyoid ligament, and (2) enlargement of this ligament were significantly correlated with transverse and anteroposterior dimensions of ligamentous ossification or osteophytes of the cervical spine at various levels. The prevalence of such abnormalities of this process and ligament was not significantly different between the patients with and without thoracic spine DISH.
Variable types of styloid process-stylohyoid ligament complex abnormalities have significant correlation with ligamentous ossification and osteophytes of the cervical spine.
探讨颈椎韧带骨化或骨赘与茎突及茎突舌骨韧带骨化之间的相关性，并确定胸椎弥漫性特发性骨肥厚（DISH）与茎突及茎突舌骨韧带骨化之间的关系。
描述了4例患有颈椎DISH、茎突延长和/或茎突舌骨韧带不同程度骨化且临床表现符合鹰综合征的患者。回顾了100例同时进行了胸椎侧位X线片检查的患者的颈椎计算机断层扫描图像。采用点二列相关分析、Spearman等级相关分析、McNemar检验、卡方检验和Fisher精确检验来确定茎突延长和/或茎突舌骨韧带骨化与（1）颈椎韧带骨化或骨赘（DISH的特征性脊柱表现）和/或（2）胸椎DISH之间的相关性。
（1）茎突延长以及茎突舌骨韧带近端、中部和远端不同程度的骨化，（2）该韧带增粗与颈椎不同节段韧带骨化或骨赘的横径和前后径显著相关。有和没有胸椎DISH的患者中，该过程和韧带的此类异常发生率无显著差异。
茎突-茎突舌骨韧带复合体的不同类型异常与颈椎韧带骨化和骨赘显著相关。
