锁骨颅骨发育不良（CCD）是一种罕见的常染色体显性遗传骨骼发育不良。为了明确咬肌骨异常的形态学特征，我们报告了3例CCD患者，通过计算机断层扫描（CT）和曲面体层摄影，发现咬肌厚度和颌面骨异常。CCD患者（a）咬肌厚度小于年龄和性别匹配的对照组，（B）下颌弓与发育不良的下颌骨不连续，（c）下颌骨升支边缘平行，（d）冠状突向上和/或向后指向。我们的结论是咬肌厚度小于正常，以及颌面骨异常的CCD患者。
Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia. In order to define the morphologic characteristics of the masseter Muscle incidental to bone abnormalities, we present 3 cases of CCD with the masseter muscle thickness and maxillofacial bone abnormalities, using computed tomography (CT) and panoramic radiographs. In CCD patients (a) the masseter muscles were less thick than in age- and sex-matched control subjects, (b) the zygomatic arch was discontinuous with the hypoplastic zygomatic bone, (c) the ascending ramus of the mandible had parallel-sided borders, and (d) the coronoid process pointed upwards and/or posteriorly. We have concluded the masseter muscles are less thick than normal, alongside the maxillofacial bone abnormalities in CCD patients.
