Reconstruction of the nasal dorsum with autologous rib cartilage

Abstract

The authors present their experience with the correction of deformities of the nasal saddleback using rib cartilage grafts. They present a review of international literature on this topic, analyzing 33 patients selected from 452 cases of rhinoplasties performed between January 1990 and December 2004 at the Department of Plastic and Reconstructive Surgery of the University of Rome "Tor Vergata." Nasal saddleback is one of the most complicated defects to correct surgically. It can be a consequence of nasoethmoid-orbital fractures and is in this case associated with other evident signs like telecanthus, teleorbitism, or orbital dystopia. It can be also a consequence of surgical procedures in the nasal area where a loss of bone or septal cartilaginous support has occurred. They compare the techniques employed in the reconstruction and describe the advantage of the use of cartilage from the 11th rib and evaluate the results of an engineering analysis of tension forces on the rib cartilage. Of the total number of patients treated, good cosmetic results were obtained in 84% of the cases and excellent functional results in almost all of the cases (94%).
