A systematic review and meta-analysis of comparison between autologous costal cartilage and alloplastic materials in rhinoplasty

Our analysis of available evidence suggests that ACC is preferred in revision rhinoplasty, which may explain its association with higher complication rates. In primary rhinoplasty, Medpor offered versatility in addition to low complication rates and good aesthetic and function outcomes. But its potential dramatic damage to the nasal tissue made secondary surgery extremely difficult. Our findings were limited by lack of high-quality evidence. Future studies with rigorous study design for head-to-head comparisons and longer follow-up are needed to establish clear guidelines for choosing the appropriate rhinoplasty graft material.
