What types of rhinoplasty fillers are available? Achieving a high, straight nose often requires fillers to enhance its appearance. So, what are the different types of rhinoplasty fillers? Below, experts provide a detailed introduction to rhinoplasty fillers.Solid silicone, currently a less commonly used rhinoplasty filler, remains one of the primary clinical choices despite its complication rate of 5%-20%. This is due to its excellent biocompatibility and high cost.Its primary drawback is the inability to establish blood circulation with the body, forming tissue adhesion. It is only encapsulated by fibrous tissue, which can lead to protrusion through the skin at weak points. Additionally, contracture of the fibrous capsule may cause the silicone implant to project on the skin surface, affecting the aesthetic outcome.Among artificial bone materials used for rhinoplasty fillers, hydroxyapatite is the primary choice due to its excellent biocompatibility and absence of toxicity, teratogenicity, allergenicity, or carcinogenicity. However, its lack of structural support limits effectiveness for patients with low nasal tips. The most advanced rhinoplasty filler currently available is expanded polytetrafluoroethylene (ePTFE). This material is widely adopted in international plastic surgery practices.It exhibits exceptional stability, does not react with other substances, and is non-toxic, non-carcinogenic, and non-teratogenic. Its smooth texture facilitates sculpting and shaping. A key advantage is its ease of complete removal should patients find the post-operative appearance unsatisfactory, leaving no residual defects. Its greatest strength lies in its lifelike feel, opacity, and the ability for blood vessels to integrate within the material, enhancing stability.
