title: A rare case of atlanto-axial fusion with dysplasia of odontoid peg in a cleft lip and palate patient.
abstract: A case of a 19-year-old female with atlanto-axial fusion and dysplasia of odontoid peg in a cleft lip and palate patient is described. Schematic drawings from radiographs were taken to compare six earlier reported cases of anterior atlas arch fusions with epistropheus including dysplasia or aplasia of odontoid peg from literature.
