What is the most common complication observed one year post-genioplasty?

• A. Malposition of the chin
• B. Infection
• C. Notching
• D. Fracture of the bone

Answer: (C)

The most common complication observed one year post-genioplasty is notching. Notching refers to the indentation or irregularity that can develop at the site of the surgical incision during the healing process, particularly if there is inadequate contouring or if the implant or bone segment fails to integrate properly with the surrounding tissue. This is especially relevant in the context of genioplasty, where the overall aesthetic outcome is crucial.

Over time, the anatomical changes that occur during healing can lead to notching, which may not be immediately evident post-operatively but can manifest as the tissues settle or remodel. It's important for surgeons to consider this potential outcome and plan surgical techniques accordingly to minimize the risk of notching.

Other complications such as malposition of the chin, infection, and fracture of the bone can occur, but they are typically less common when appropriate surgical practices are followed. Malposition, while possible, often results from surgical technique or misjudgment, and infections tend to present earlier in the post-operative period rather than after a full year. Bone fractures are generally rare with standard genioplasty procedures. Therefore, the risk of notching becomes more pronounced and recognized as the primary complication over a year following the surgery.
