HOLOPROSENCEPHALY: A CASE REPORT

Abstract

Holoprosencephaly which is characterized by severe facial anomalies is a developmental defect in which the cerebral hemispheres could not split sufficiently into two lobes. The disease can be graded into three as alobar, semilobar and lobar according to the degree of severity. Cyclopia and premaxillary agenesis are the facial findings of the most severe forms while microcephaly and hypoteleorism are the less severe facial anomalies. Solitary median maxillary central incisor, midline cleft palate, absence of the labial frenulum and arch-shaped upper lip are the most common dental findings. The prognosis of holoprosencephaly which could also be an isolated anomaly depends on the severity of the brain and facial deformities and associated anomalies. Although, the etiology in the majority of the cases does not exhibit chromosomal disorder, an autosomal dominant inheritance is observed in some families. Maternal diabetes, toxoplasmosis, viral enfection and various drugs (phenytoin and salicylates) used during pregnancy have been suggested as risk factors. The aim of the this study was to examine the midline defects of a 5 years-old girl who had been diagnosed as semilobar holoprosencephaly and discuss these findings in regard with the literature.
