Abstract

Neural crest cells have embriologically important role for the development and growth in oral and maxillofacial region. If the early hereditary defect occurs or environmental factors affect these cells diminutive mesenchymal cells are disabled to make neural plate and decreased proliferation of mesenchymal cells result in hypoplastic development of neural crest. As a result, this brings about severe facial malformations such as various located facial clefts and/or loss or duplication of facial structure. These are two cases of accessory maxilla and zygomatic deformity with and without facial cleft.
