Bilateral Maxillo-Mandibular Syngnathia in a Newborn

A 5-day-old newborn, product of non-consanguineous marriage, presented with inability to completely open oral cavity and feeding difficulty. On examination, there was a good sucking reflex and limited mouth opening (Fig. A) with retrognathia (Fig. B). Maxillary CT with 3D reconstruction revealed hypoplasia of the ascending branches of the mandible; the temporomandibular joints were normal (Fig. C, D) with bilateral Maxillomandibular Syngnathia (Fig. E, F).
