title: Use of distraction osteogenesis in arrhinia.
abstract: Nasal malformations such as hemiarrhinia and arrhinia have a very low incidence, although many treatment protocols have been described. In this article, we describe 2 surgical techniques to treat arrhinia depending on the age at the beginning of treatment. In our practice, we use Le Fort III osteotomy with distraction osteogenesis as a pillar of the reconstruction because it allows to improve anteroposterior and vertical projections of the midface, giving a proper platform for nasal reconstruction, decreasing the number of interventions. We report a patient with a hemiarrhinia who has completed appropriate reconstruction results and a patient with total arrhinia in whom the distraction was achieved to create a nasal bone support and improve midface projection.
