Glossopalatine ankylosis

A rare oromandibular-limb hypogenesis syndrome (OLHS) characterised by the presence of an intraoral band of variable thickness attaching the tongue to the hard palate or maxillary alveolar ridge. It may be associated with other abnormalities such as cleft palate (in which case the tongue may be attached to the nasal septum), mandibular hypoplasia, upper-lip hypoplasia, hypodontia and variable limb anomalies (e.g. oligodactyly, syndactyly and polydactyly).
