A patient with Charlie M Syndrome: Differential diagnosis of Oromandibular Limb Hypogenesis Syndromes.

Aim: In order to provide adequate treatment to a patient with a subtype of Oromandibular Limb Hypogenesis Syndromes (OLHS), this study aimed to review and to analyze the current literature and treatment options of OLHS.

Methods: Literature review in PubMed and Sciencedirect. Due to the small number of results, all available references were analyzed precisely.

Results: Cases of OLHS are formerly rare and often incomplete. There are various classifications available, which, however, often seem confusing and are of little practical relevance. Furthermore, we present a complete case report of a patient with Charlie M syndrome, a type IV (Chicarilli)/ V (Hall) OLHS malformation. We also describe embryologic pathogenesis and differential diagnoses.

Conclusion: As a result of our literature review, we recommend an adjusted classification for OLHS.
