While silicone remains the most commonly used material in prosthetic rhinoplasty, many also opt for autologous cartilage. Compared to silicone implants, autologous rhinoplasty offers distinct advantages that have secured its place in the market.
Advantages of autologous rhinoplasty:
1. The procedure is straightforward, using the patient's own tissue, eliminating the risk of rejection;2. The texture feels natural. After autologous rhinoplasty, normal contact with the nose is not a concern. The nasal tip can be gently pressed, and the feel is soft and realistic. Autologous cartilage is typically harvested from the ear, nasal septum, or ribs.
3. Autologous tissue exhibits excellent biocompatibility and stability, integrating seamlessly with local nasal structures. It remains firmly fixed and is resistant to displacement.
4. Autologous grafting boasts low absorption rates and maintains viability even without blood supply.
Postoperative Care for Autologous Rhinoplasty:
Avoid touching the surgical incision with hands and prevent water exposure.Intranasal sutures are removed 5-7 days post-op. Local swelling typically subsides gradually after four days. Antibiotics are recommended for 3-5 days to prevent infection. Avoid spicy or irritating foods for 7 days post-op, and refrain from smoking for two weeks. Minimize strenuous activities to prevent implant displacement. Avoid violent impacts for two months.
Editor's Note:
If septal cartilage is chosen as the autologous graft material, its limited harvestable quantity typically permits use only for tip and columella augmentation. Partial resorption occurs, generally below 15%.
If rib cartilage is used for autologous rhinoplasty, residual scarring will remain on the chest. This method involves slightly greater trauma, and transplanted rib cartilage may bend or deform over time.
When using ear cartilage for autologous rhinoplasty, the limited quantity 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 also occurs, typically at a rate below 15%.
