Outcomes and complications of autologous versus alloplastic grafts in augmentation rhinoplasty: A systematic review of studies from 2000 to 2024.

Twenty‑eight studies met inclusion criteria, representing diverse geographic regions and graft practices.

Autologous grafts, especially costal cartilage, were associated with lower infection and extrusion rates, but carried risks of warping and occasional resorption.

Alloplastic implants, most commonly silicone and Gore‑Tex, provided operative efficiency but demonstrated higher infection and extrusion rates, particularly in long‑term follow‑up.
