In general the risks of rib cartilage grafting include: Graft asymmetry or warping. With an experienced surgeon this risk is lessened significantly. Injury to the underlying lung during graft harvest (also rare with an experienced surgeon) stiffer nose after surgery Poor healing of the chest incision. Ask your surgeon what length incision they use (this varies among surgeons). The chest incision typically heals very well. risks of surgery in general such as bleeding, infection, anesthesia, etc. Depending on your anatomy, septal cartilage and/or ear cartilage may be used. Needing a large volume of cartilage for reconstructing your bridge is often best done with rib, though.
Thank you for the great question. Using autologous (from you) rib in rhinoplasty is generally safe. The long-term complication that is most feared with costal cartilage grafts is warping -- or shape change/curvature of the graft material over time. Certain techniques are used in surgery to limit this, but it is unfortunately not completely predictable. The other possibility is graft resorption (the grafts don't survive and the nose loses volume again).The alternatives in cases where a significant amount of grafts are needed are less appealing. With implants in the nose, there is a risk of infection and extrusion over time, in addition to the risks of settling or shifting. This is not an easy decision, but, in my opinion, using your own tissue is always better.
Optimally, one of the most important aspects in rhinoplasty, both primary and secondary, is to use autologous tissue if needed. These are the most challenging operative procedures that we do in aesthetic plastic surgery, therefore, it’s very important to choose an experienced rhinoplasty surgeon. Find someone that has significant expertise in secondary rhinoplasty surgery as this is a very challenging and difficult operative procedure. One can never totally restore one to a normal nose especially if you’ve had multiple operative procedures. The use of rib grafts are used if there is loss or collapse of the nose and/or tip. However, it is not without its problems including potential temporary chest wall pain and warping of the cartilage itself short or long term. I will use it in those patients where I can not use any other autologous material like septum or the ear and certainly in the dorsum if I need to augment it more than 4-6mm, I will definitely use rib.
Rib cartilage's main advantage is its plentiful supply. The main risks of rib cartilage are: Risk of pneumothorax- Pneumothorax is a "popped lung". This can occur when harvesting rib from the chest area. This is not common with an experienced rib revision surgery. Risk of warping- Warping can occur with rib cartilage. Decreasing the incidence of warping significantly by experience in carving costal cartilage. There are several techniques for doing this. Scarring- Rib rhinoplasty requires a scar on the chest. Most patients can have a limited incision scar which can limit postoperative visbility of the area. Overly stiff nose- Rib cartilage is a stiffer material and can make the nose a stiffer feeling Overly wide nose- Rib cartilage can make the nose wider. Ideally, it is carved into narrower portions to limit issues with width post procedure Infection- Any graft has the risk of infection Postoperative pain- Rarely patients can experience pain in area where rib was harvested
In revision rhinoplasty, it is usually necessary to reconstruct and reshape the nasal framework using cartilage grafts. Because available septal cartilage has usually been removed during the first surgery, grafts must obtained from another site - either the ear or the rib.Rib cartilage has many uses and advantages in revision rhinoplasty. It can be carved or shaped to the desired configuration. Its rigidity can provide support to a weakend nasal framework. Drawbacks of Rib Cartilage Include:* Rendency to warp (curve). This can make the result unpredictable. * Nose may feel firm or inflexible.Potential Risks of Rib Cartilage Harvest:* Bleeding * Prominent scar * Pain * Infection * Collapsed lung (pneumothorax) * Chest wall deformityHowever, in experienced hands, rib cartilage allows successful results in revision rhinoplasty.
