[Repair of nose, lips and chin mutilations. The customary repairs versus allografts].

Central-facial mutilations, located within the nose lips and chin triangle, require great quality repairs regarding morphology and function. Plastic surgery history affords the ideas evolution in this field crossing over nose and lips reconstructions, which were the subject of successive reports within our society, in 1994 (nose reconstruction) and 2002 (lips reconstruction). Now a day, following this progress, the plastic surgeon has a large choice of reliable techniques. His choice is dictated by a precise evaluation of the limits of the substance loss to repair, according to a (mapping) classification of the nose-lip and chin triangle. This classification defines three units (nose-labial, bilabial and chin-labial) as reflexion bases to the therapeutic indications. This anatomical and surgical approach was built starting from a retrospective study of 195 central-facial mutilations caused by ballistic damage and dog bites. The results evaluation makes possible to carry out a reflexion on the potential indications regarding allograft as a therapeutic alternative to the traditional reconstructions of this territory.
