Trismus‐pseudocamptodactyly syndrome (TPS) (OMIM#158300), also known as Hecht syndrome, is a rare autosomal dominant distal arthrogryposis. Bilateral hyperplasia of the coronoid processes has been reported to cause trismus. In this study, we report a case of TPS definitively diagnosed on the basis of clinical signs in a patient who had bilateral hypoplastic mandibular condyles and shallow mandibular fossa; TPS in such patients have never been reported in the literature. On the basis of the present case, we propose that a hypoplastic mandibular condyle and shallow mandibular fossa are also clinical features of TPS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
