Congenital fusion of the mandible and maxilla is a rare anomaly usually seen in association with various syndromes. Reports of isolated cases of bony fusion of the jaws are sparse. Only 10 reported cases were found in the literature search. Maxillomandibular fusion restricts mouth opening, causing feeding problems and difficulties in swallowing, respiration, growth, and development, and thus must be treated early. We report a case of congenital fusion of the mandible and maxilla in a 1-year-old boy and describe the clinical features of this anomaly to add to the existing literature on the subject. This is our second encounter of such a case.

Background: Congenital muscular dystrophies (CMDs) and myopathies (CMYOs) are a clinically and genetically heterogeneous group of neuromuscular disorders that share common features, such as muscle weakness, hypotonia, characteristic changes on muscle biopsy and motor retardation. In this study, we recruited eleven families with early-onset neuromuscular disorders in China, aimed to clarify the underlying genetic etiology.
Methods: Essential clinical tests, such as biomedical examination, electromyography and muscle biopsy, were applied to evaluate patient phenotypes.

The combination of congenital C1 occipitalization and C2-3 non-segmentation (i.e. "sandwich fusion") results in early development of atlantoaxial dislocation (AAD).

Variations in the development of carpal bones are uncommon, with the scaphoid bone typically forming from the fusion of the os centrale carpi and the radial chondrification center during embryogenesis. A bipartite scaphoid is a rare congenital disorder that occurs when these ossification centers fail to fuse, with a prevalence ranging from 0.1% to 0.

Intradural extramedullary bronchogenic cysts (IEBCs) are exceedingly rare congenital entities, composed of respiratory epithelial cells derived from the anomalous development of the embryonic foregut. Due to their exceptionally low morbidity, only limited cases are available. Consequently, the clinical features and optimal therapeutic approach remain poorly understood.

Background: Morphological and structural abnormalities are common dental anomalies. Identifying DA and determining their prevalence can play an important role in reducing the risk of surgical intervention and improving occlusion, leading to successful dental treatments. Thus, this study aimed to determine the prevalence of DA using panoramic radiographs (OPG) in Makkah, Saudi Arabia according to gender.
