There are many options to augment a nasal bridge, each with its pros and cons. There is no perfect solution.
1. Cartilage: septal cartilage is ideal when sufficient cartilage is available. This is not always the case in revision cases. Ear cartilage tends to warp as well as resorb.
2. Rib cartilage works well but can warp and there is more donor site morbidity/downtime.
3. Alloplast implants i.e. medpore, gortex, silastic work well but have a higher risk of infection and potential extrusion in the future. These are very popular because they are readily available and easy to use.
Your surgeon will assess your particular need and determine which implant is best suited for your nose.
