RESUMEN
Hallermann-Streiff syndrome (HSS) is a rare congenital abnormality affecting mostly the head and face area. Craniofacial deformities, which are present in 98-99% of cases, are the principal abnormalities detected. We focus here on a particular subset of these deformities: atrophy of the skin of the centre of the face and nose. Two patients diagnosed with HSS were treated in our department. Both patients underwent nasal lipofilling to treat the atrophy of the nasal skin, as described by Nguyen et al. In both cases, a satisfactory improvement in nasal skin colour and texture was observed. A functional gain was also reported by the parents and observed during follow-up consultations. Lipofilling thus appears to be an excellent option for treating craniofacial deformities in children.
