Syngnathia in Spectrum of Oromandibular Limb Hypogenesis Syndrome.

Syngnathia is a rare facial anomaly associated with neonatal problems, including a compromised airway, and the inability to take in solids and/or liquids. Syngnathia is included within the spectrum of oromandibular limb hypogenesis syndrome, an extremely rare condition characterized by varying degrees of congenital malformation involving the tongue, mandible, and limbs. In this report, we describe the case of a 41-day-old Caucasian female infant who was unable to open her mouth beginning at birth. The authors performed osteotomies to separate fused bone, and placed a bite block at the osteotomy sites to prevent bone fusion recurrence. At 2 years of follow-up patient remained with 14 mm of mouth opening.
