Résumé
Septorhinoplasty by disarticulation is an esthetic and functional solution for naturally occuring nasal pyramid dysmorphia, releasing the anatomic traces of growth-related stresses. Disarticulating the septolateral cartilage from its bony framework via a closed approach to the septal pocket is associated to Rethi's external approach in order to disarticulate the fibrocartilaginous nasal dorsum, while conserving its integrity, under the bony dorsum. The bony pyramid is then disarticulated down to the nasion, after resecting any bone hump, by 2 paramedian and 2 low lateral osteotomies in the basal groove. The lateral sides of the bony pyramid are then fractured at their posterior edges by percutaneous pinching to close the open roof and realign them along the midline. The septolateral cartilage, reduced as necessary at the inferior and anterior edges, is thereafter repositioned on the premaxillary bone. Traction on its anterior edge restores rectilinear frontal and lateral tension in the fibrocartilaginous dorsum, fully conserved from its attachment to the nasion. This technique corrects any septal deformity and restores frontal and lateral dorsum straightness.
