[Secondary rhinoplasties: failures at the bone stage].
Based on a personal experience, the author exposes the problems and describes the failures who can occur during and after the "bony stage" of the rhinoplasty. The surgical treatment will be exposed. Successively: correction of the dorsum (resection of the bony hump) with incorrect nasofrontal angle, residual hump, "saddle nose"; lateral osteotomy and bony step; transversal and paramedian osteotomy with possibility of "open roof" so as residual deviation.
