[A new look on septoplasties: an anatomo-clinical study and surgical procedures of the 4 main septoplasties].

The aim of a nasal septum surgery is functional and aesthetic aims. With a semiologic study the authors analyse four kinds of septoplasties which allows to correct the main septal deviations: erndoscopic septoplasty for posterior nasal obstruction, Cottle's septoplasty for septum's luxation and deviation on the premaxilla area, septoplasty with spreader grafts for dorsum cartilage deviations, extracorporeal septoplasty with a new septum cartilage frame for the complex deviations. The authors emphasize on the help given by videoendoscopy during the surgical procedures.
