Otopalatodigital syndrome spectrum disorders are caused by Filamin A (FLNA) gene mutations. Otopalatodigital syndrome spectrum disorders are a group of rare congenital skeletal dysplasia, with specific craniomaxillofacial features including otopalatodigital syndrome type 1 and type 2, Melnick-Needles syndrome, frontometaphyseal dysplasia, terminal osseous dysplasia with pigmentary defects. The authors describe cases of a young girl with Melnick-Needles syndrome and a young boy with frontometaphyseal dysplasia treated in the Oral and Maxillofacial Surgery Department. Both patients had FLNA gene mutation confirmed with molecular genetic analysis. The authors proposed a 4 step treatment of the malformations with good outcomes both aesthetically and functionally, without complication.
