Challenges in Nasal Cartilage Tissue Engineering to Restore the Shape and Function of the Nose

implantation, to definitively assess the success of nasal cartilage tissue engineering. Here, we review the tissue engineering methods to repair nasal cartilage, focusing on the type and mechanical characteristics of the biomaterials; cell and implantation strategy; and the outcome with regard to cartilage repair. Impact statement Nasal septal cartilage is key to the cosmetic and function of the nose. To repair important damage to the nasal septum, current surgical techniques are complex and limited by graft source availability. Conversely, tissue engineering is a promising strategy to reproduce the dimensions and mechanical properties of the nose without causing donor site morbidity. This approach, however, remains overlooked for the reconstruction of the nasal septum compared with other cartilaginous tissues. This review describes the specific challenges associated with nasal cartilage repair and the pioneering studies leading to advances in the growing field of nose tissue engineering.
