Why does a nose implant become deformed after several years?

The reasons for nasal implant deformation after several years may include the following: 1. **Material-related issues**: Silicone implants may cause foreign body reactions due to individual differences and variations in the microenvironment of the implantation site, such as local inflammation and edema, which may lead to deformation. Infection of expanded polytetrafluoroethylene (ePTFE) implants is also a cause of deformation, as inflammatory reactions triggered by bacterial invasion can alter the implant's shape. 2. **Surgical technique**: During surgery, improper shaping of the implant or creating a pocket that is either too large or too small may lead to implant instability after placement, thereby increasing the risk of deformation. 3. **Postoperative care**: Improper care during the early postoperative period, such as touching or bumping the nose too early, may also cause implant displacement or deformation. 4. **Tissue encapsulation**: Excessive tightness of the tissue capsule surrounding the implant may restrict implant mobility and consequently lead to shape changes. To prevent implant deformation after rhinoplasty, it is recommended to choose an experienced surgeon for the procedure and to follow proper postoperative care and regular follow-up examinations.
