1/2. Morphologic characteristics of masseter muscle in cleidocranial dysplasia: a report of 3 cases.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.- - - - - - - - - - ranking = 1keywords = masseter muscle, masseter, muscle (Clic here for more details about this article) |
2/2. A case of progressive scoliosis in a patient with craniocleidopelvic dysostosis.The authors describe a case of craniocleidopelvic dysostosis in a patient with progressive scoliosis. They attribute the pathogenesis of the vertebral deformity to imbalance of the shoulder girdle muscles and dysplasia of the vertebral metameres. They agree with the majority of authors in regarding craniocleidopelvic dysostosis as a specific clinical manifestation of a complex hereditary syndrome.- - - - - - - - - - ranking = 6.274873199536E-6keywords = muscle (Clic here for more details about this article) |
