Fresh Frozen Cartilage in Rhinoplasty Surgery: A Systematic Review of Outcomes.

[INTRODUCTION] Cadaveric fresh frozen cartilage provides an enticing alternative to traditional autologous cartilage grafts. This review provides a systematic analysis of existing literature on the use of fresh frozen rib for in rhinoplasties and focuses on clinical and aesthetic outcomes.

[METHODS] The methodology was designed and registered in the PROSPERO database (CRD42023447166). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline was used to perform this systematic review.

[RESULTS] Four articles were included, with a total of 554 patients. A total of 477 patients were female (86%). Mean age ranged between 35.8 and 40.6. Mean follow-up ranged from 12.2 to 20.3 months. Only one article had a suitable control (with autologous rib graft). Pooled complications rates were low. Infection occurred in 12 patients (2%), warping in 8 patients (1.4%) and resorption in 3 patients (0.5%).

[CONCLUSION] Fresh frozen cartilage may be a safe and reliable alternative to autologous rib grafts. Complication rates were comparable to previous systematic reviews of autologous graft and irradiated allograft. Overall, patients reported high satisfaction rates with low rates of revision procedures. Further studies are required to assess both clinical and cost effectiveness against the current gold standard (autologous graft).
