Craniometaphyseal dysplasia as a rare cause of a severe neonatal nasal obstruction.

We report on a 2-year-9-month-old boy with the typical features of craniometaphyseal dysplasia with hyperostosis and sclerosis of the cranial vault and mild splaying of the metaphyses. The boy already presented during the neonatal period with the unusual clinical picture of breathing and feeding problems due to severely enlarged and ossified inferior nasal conchae causing obstruction of the nasal lumen.
