Terminal Transverse Defects with Orofacial Malformations (TTV-OFM): Case Report with Mandibular Prognathism and Submucous Cleft Palate ALVARO FIGUEROA, D.D.S SAMUEL PRUZANSKY, D.D.S. Chicago, Illinows 60680 Terminal transverse defects of varying severity, ranging from aplasia of phalanges and digits to hemimelia, have been reported in association with various orofacial malformations. Temtamy and McKusick (1978) introduced the term "terminal transverse defects with orofacial malfor- mations (TTV-OFM)" as a formal genesis syndrome (etiologically undefined) to include the following clinical entities: (1) aglossia-adac- tylia syndrome; (2) ankyloglossum (superius) syndrome; (3) Hanhart syndrome; (4) ectrodactyly with OFM; and (5) Mobius syndrome with digital malformations (including the Charlie "M" syndrome). This report describes a patient whose phenotypic characteristics qualify for inclusion under this heading, but with facial features somewhat differ- ent from those previously reported in the literature including the presence of an eccentric submucous cleft of the hard palate and zona pellucida of the soft palate.
