Construction of Bony-Cartilaginous Defects of the Nose

Abstract

Bony and cartilage defects of the nose should be reconstructed for both esthetic and functional purposes. In the past, autogenous bones, such as rib bones, cranial bones, and other bone grafts, have been used to reconstruct bony defects of the nose. Rib and ear cartilage have been used to reconstruct cartilage defects of the nose. A congenital subtotal bony-cartilaginous defect of the nose was reconstructed using cranial bone for the nasal bony defect, ear cartilage for the tip cartilage deficiency, and rib cartilage for the septal defect, in the present patient.

Three-Dimensional Printing Strategies for Irregularly Shaped Cartilage Tissue Engineering: Current State and Challenges

“…The materials commonly used for nasal scaffold transplantation include bone or cartilage obtained from the nasal septum, ribs, skull, and ear ( Parkhouse and Evans, 1985 ). However, there is a risk of graft fracture and displacement when using a graft to repair the loss of nasal cartilage ( Elik and Aktan, 2019 ; Cao et al, 2021 ). Therefore, the application of 3D printing in cartilage tissue engineering can provide a rational alternative for fabrication of nasal cartilage prostheses suitable for a given individual.…”
