Abstract:
Naso-ethmoido-maxillary protrusion (NEMP) is a rare dental and facial dysmorphosis, with excessive growth of basicranium, ethmoid, maxillary, and nasal bones. The clinical presentation includes nasal and upper lip protrusion, telecanthus, a class 2 malocclusion with maxillary protrusion and exoclusion. The craniofacial field is increased in Delaire's analysis. Contrary to isolated maxillary protrusion secondary to membranous ossification dysfunction, NEMP is a constitutional anomaly resulting from an excessive primary growth of the chondrocranium. The therapeutic management of NEMP should take into account these specificities.
