Le syndrome de Langenbeck: quelles répercussions sur la cinétique mandibulaire ?

Abstract

Langenbeck syndrome or mandibular coronoid process hyperplasia is a rare disease characterized by an increase in the volume of the coronoid processes. This hyperplasia causes bone conflict with limitation of mouth opening. Surgeons must be awareness of this rare disease, included in differential diagnosis of mouth opening limitation. We present a case successfully treated in our department. Successful management includes both bilateral intra-oral coronoïdectomies and supportive post-operative follow-up with maxillofacial physiotherapy.
