Congenital bilateral intermaxillary bony fusion.

Congenital fusion of maxillary and mandibular alveolar margins is extremely rare. Bony fusion between the jaws is still more uncommon. Only eight patients with bony fusion have been described in the literature to date, of whom only three had bilateral bony fusion. We present here a patient with very extensive bilateral bony fusion of the jaws, who underwent surgery with excellent immediate postoperative results. Details of the surgical management of this rare and difficult problem in a neonate with poor general condition are described.
