This is Dr Özge Ergün First of all thank you for your photo, Achieving optimal facial harmony often necessitates correcting a mild to moderate degree of microgenia (a recessed chin) to improve the overall profile aesthetic. For this purpose, two primary surgical modalities are utilized: Osseous Genioplasty (also known as a Sliding Genioplasty) and Alloplastic Chin Augmentation (Chin Implant). Osseous Genioplasty offers the benefit of utilizing the patient's native bone structure. This procedure involves a controlled mandibular symphysis osteotomy (cutting the chin bone), allowing for multi-dimensional repositioning—typically a maximum horizontal advancement of approximately 10 \textmm (1 \textcm). The mobilized segment is then rigidly secured in its new, aesthetically planned position using titanium mini-plates and screws. While highly effective and offering permanent, natural contour, it is considered a more invasive procedure due to the bone manipulation required. Alloplastic Chin Augmentation is a less technically demanding and generally less traumatic alternative to osseous genioplasty. It involves the precise placement of a solid, biocompatible implant. Common materials include porous polyethylene (Medpor) or silicone block implants, which are designed to mimic the underlying bony structure. For implant placement, the incision can be made either intraorally (inside the lower lip, which eliminates visible external scarring) or, for greater stability and ease of surgical access, via a small submental incision (under the chin, typically well-concealed). Anatomically shaped implants are generally preferred as they provide the most natural and aesthetically pleasing transition from the mandible to the augmented chin point.
