Description

It is necessary for dentists to control the mandibular hypomobility in children even if it happens relatively rarely. In this case report, we present two different causes for limitation of mouth opening.<BR>They have morphological abnormalities in their unilateral masticatory muscles on the CTs, but there is no abnormal finding around their temporomandibular joints. Case 1 is a 3 year-old boy who had a history of cranial operations several times due to multi-located brain vascular malformations. On his CTs, atrophic changes were detected in some masticatory muscles that were controlled under facial and trigeminal nerves. Case 2 is a one-year old boy who has a congenital wryneck. His temporal muscle reveals hypertrophy on his CTs. Dystonia of masticatory muscle was suspected from these findings as well as his sternocleid muscle of his wryneck. At the present time, it is very difficult to detect in detail such as electro-myographies about their pathology because of his younger age. Therefore, we will observe his oral conditions and follow up for a long time.
