Duplication of hemi mandible and oral cavity, presentation of an adult patient – a case report

Duplication of lower lip and mandible—A rare diprosopus

“…There were many variations in relation to structures, e.g. presence of both upper and lower lips [1,2], absence of both lips [4] and presence of one lip [3]. Our case is similar to the case described by Maisels [3].…”

“…Shaikh et al reviewed the literature and showed that the duplication of the midface was more commonly described than mandibular duplication [4]. There were many variations in relation to structures, e.g.…”

“…McLaughlin was the first to describe it in 1948, and following that several other authors attempted to illustrate this rare anomaly [1][2][3][4]. Wu et al reviewed the literature and reported that approximately 100 cases of complete or incomplete craniofacial duplication were identified [5].…”

"Partial duplication of lower lip and hemimandible" A rare case

“…[9] Shaikh et al reviewed the literature and showed that the duplication of the mid face was more commonly described than mandibular duplication. [5] Bhattacharya et al reported a rare craniofacial cleft with duplication of alveolar arch. [17] Our case is similar to the case described by Suhaili et al and Maisels et al [3,6] The human face develops from the frontonasal process, pair of maxillary processes and a pair of mandibular arches centered around the stomodeum [ Neural crest cells arise along the entire edges of the neural folds, under the signaling of BMP proteins.…”

“…McLaughlin was the first to describe it in 1948 and following that several other authors have attempted to illustrate this type of rare craniofacial anomaly. [1][2][3][4][5][6] Wu et al reviewed the literature and identified the spectrum of complete or incomplete craniofacial duplication. [7] It was believed that this condition was a congenital anomaly and not a teratoma.…”
