Summary
Forehead augmentation using methylmethacrylate (MMA) with an injection-molding technique offers a safe and effective method for facial contouring. This procedure achieved satisfactory aesthetic results with a low re-operation rate in a large patient cohort.
Area of Science:
- Plastic Surgery
- Aesthetic Surgery
- Craniofacial Surgery
Background:
- The forehead significantly influences facial aesthetics, determining masculine or feminine appearance.
- Previous forehead augmentation methods include autologous fat grafts and alloplastic materials.
- Methylmethacrylate (MMA) is identified as a suitable material for forehead augmentation.
Purpose of the Study:
- To evaluate the efficacy and safety of an injection-molding technique using MMA for forehead augmentation.
- To assess patient satisfaction and complication rates associated with the procedure.
Main Methods:
- The study involved 516 patients undergoing forehead augmentation over 13 years.
- The procedure utilized an injection-molding technique with MMA under local anesthesia and IV sedation.
- Subperiosteal dissection was performed, followed by MMA injection and manual molding.
Main Results:
- The injection-molding technique ensures close apposition of the MMA implant to the frontal bone, minimizing gaps.
- Implant borders were tapered for a natural, non-palpable, and non-visible finish.
- A low re-operation rate of 5.4% (28 patients) was observed due to undesirable outcomes.
Conclusions:
- The injection-molding technique with MMA is a simple, safe, and ideal method for forehead augmentation.
- The technique provides satisfactory aesthetic results and minimizes complications.
- This method is recommended for patients seeking to enhance their forehead appearance.
