I. Advantages of Autologous Cartilage Rhinoplasty
1. Autologous cartilage rhinoplasty is straightforward to perform. The cartilage is harvested from the patient's own body, making acquisition easy. Common sources include ear cartilage, septal cartilage, and rib cartilage.
2. Autologous cartilage is highly malleable and easy to sculpt into the desired shape, making it an ideal material for rhinoplasty.Conventional nasal implants (silicone implants) have a fixed shape (L-shaped) and cannot create a beautiful nasal tip, whereas using ear cartilage can perfectly achieve this effect. Autologous rhinoplasty eliminates risks of nasal tip deformation or perforation;
3. Autologous cartilage rhinoplasty feels natural. After surgery, you need not worry about normal contact with the nose; you can gently press the tip, and it feels soft and realistic;
4. Autologous cartilage rhinoplasty offers excellent tissue compatibility and stability. It integrates seamlessly with local nasal tissues, ensuring secure fixation without displacement;
5. Autologous cartilage rhinoplasty eliminates the risk of rejection reactions;
6. Autologous cartilage exhibits minimal resorption and low absorption rates, maintaining viability even without blood supply;
II. Disadvantages of Autologous Cartilage Rhinoplasty
1. When using septal cartilage as the graft material, the limited harvestable volume typically restricts its use to tip and columellar augmentation. Partial resorption occurs, with rates varying individually but generally below 15%.
2. When using rib cartilage, residual scarring remains on the chest. This method involves greater trauma, and transplanted rib cartilage may bend or deform over time;
3. When using ear cartilage for autologous rhinoplasty, the limited quantity of ear cartilage makes it suitable only for elevating the nasal tip, not the columella. Due to the curvature of conchal cartilage, the columella may develop a bend post-operatively.Partial resorption occurs, with absorption rates varying by individual, typically below 15%.The autologous rhinoplasty method involves the septal cartilage—a plate-like structure separating the two nasal passages. By preserving portions anteriorly and superiorly while harvesting the posterior-inferior segment intact, both nasal contour integrity and sufficient graft material are maintained. Moreover, harvesting occurs within the same surgical field as rhinoplasty, eliminating the need for additional incisions—truly a three-in-one solution.
