The Robin sequence associated with partial maxillary duplication and multiple facial clefts: a case report.

Abstract

A case is presented of a male child of recent Yugoslav immigrants born with bilateral facial clefts, bilateral cleft lip and palate and severe micrognathia. Dental evaluation at 2 years revealed a very prominent premaxilla with hypoplastic maxillary deciduous central incisors. The mandible was markedly retrognathic with the patient exhibiting drooling. Panoramic radiographs revealed the presence of all deciduous teeth in addition to a duplication of the right maxillary molar teeth.
