Congenital Syngnathia as a Part of Oro-Mandibular Limb Hypogenesis Spectrum: Case Report

Abstract

Syngnathia (congenital union of the maxilla and mandible) is uncommon and can range in severity from mucosal bands (synechiae) to complete bone fusion (synostosis). Most of them appear as unilateral, incomplete fusion. Bony fusion (syngnathia) without any other systemic disease or congenital abnormality is extremely uncommon. Oro-mandibular limb hypogenesis syndrome, which includes syngnathia, is an extremely rare disorder characterized by variable degrees of congenital abnormalities involving the tongue, jaw, and limbs.
