Case of congenital mandibular malformation: A rarity

The condition known as craniofacial duplication, or Diprosopus, is an exceedingly rare occurrence. The term “Diprosopus” originates from Greek, meaning “two-faced person.” This condition can involve a wide range of anomalies, from complete duplication of facial features to partial duplication of specific facial structures. It is a congenital developmental abnormality typically identified during prenatal development or in the early stages of a child’s growth. Formerly, it was believed to be an anomaly rather than a teratoma. The first documented report of this unique phenomenon was by Mclaughlin in 1948, and it was also recognized as a form of conjoined twinning. The classification system for this condition is based on the specific structures that exhibit duplication, resulting in four distinct types. Notably, this report discusses an extraordinary case involving the irregular growth of the mandible in a seven-year-old girl. This case is marked by the growth of an accessory structure stemming from the lower border of the mandible and is associated with developing tooth buds. The report delves into the diagnosis and management of such a unique and complex case.
