Summary
Polymethyl methacrylate implants offer a safe and durable solution for forehead and supraorbital arch reconstruction after frontobasal injury surgery. This alloplastic material provides satisfactory aesthetic results with a high success rate.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Biomaterials Science
Background:
- Radical surgery for frontobasal injuries or frontal sinus diseases may necessitate sinus obliteration.
- Post-surgical cosmetic correction of the forehead and supraorbital arches is often required.
- Various alloplastic materials are available for reconstructive procedures.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of polymethyl methacrylate (PMMA) implants for cosmetic correction of the forehead and supraorbital arches.
- To assess the durability and aesthetic outcomes of PMMA implants in patients undergoing reconstructive surgery for frontobasal injuries.
Main Methods:
- Utilized polymethyl methacrylate implants for cosmetic correction of the forehead and supraorbital arches in patients requiring post-surgical reconstruction.
- Monitored implant behavior and patient outcomes for up to 25 years following the surgical procedure.
Main Results:
- Achieved a high success rate of 94.7% (18 out of 19) with polymethyl methacrylate implants.
- Observed one case (5.3%) of mild implant border sagging, indicating a low failure rate.
- Polymethyl methacrylate demonstrated ease of workability, non-invasiveness, and stability in vivo.
Conclusions:
- Polymethyl methacrylate implants provide a safe, durable, and aesthetically pleasing solution for correcting forehead and supraorbital deformities after frontobasal injury surgery.
- The two-step surgical approach, involving initial injury management followed by PMMA implantation, yields satisfactory long-term results for patients.
