Oral findings and craniofacial morphology in a patient with Schwartz-Jampel syndrome and severe obstructive sleep apnea: A case report.

We reported dental and craniofacial characteristics of an SJS patient with severe OSA. Not only does the syndrome cause skeletal abnormalities and myotonia, but it also affects the craniofacial development resulting in a severe constriction of maxillary arch and bimaxillary retrognathia which may increase a risk to develop pediatric OSA.
