A step-off deformity following a sliding genioplasty can be a bothersome issue. The approach to correcting this deformity depends on its severity and your specific anatomical considerations. Hyaluronic Acid (HA) Dermal Fillers: Pros: These are minimally invasive and can offer a temporary solution by smoothing out irregularities and improving contour. The procedure is relatively quick, with minimal downtime. Cons: Fillers are not permanent and typically last between 6 to 18 months. They might not provide sufficient correction for more pronounced deformities. Solid Implant Material or Bone Graft: Pros: These options can provide a more permanent and stable correction for significant step-off deformities. Solid implants or bone grafts can be tailored to match the defect precisely. Cons: Surgical intervention carries more risks, including infection, prolonged recovery time, and potential complications related to the implants or grafts. Ultimately, the best approach depends on your individual case, including the extent of the deformity and your personal preferences. I recommend consulting with a board-certified plastic surgeon or maxillofacial surgeon who can evaluate your specific situation and discuss the most appropriate treatment options for you.
