Summary
Porous polyethylene implants in the paranasal area corrected midface concavity without affecting dental occlusion. This surgical technique showed no complications in a mean 33-month follow-up for midface retrusion.
Area of Science:
- Plastic Surgery
- Craniofacial Surgery
Background:
- Congenital, posttraumatic, and cleft-related midface retrusion present challenges in craniofacial reconstruction.
- Skeletal osteotomies and advancement are traditional methods but can alter dental occlusion.
Observation:
- Porous polyethylene implants were utilized in the paranasal area to address central midface concavity.
- This approach aimed to simulate skeletal advancement without impacting dental occlusion.
Findings:
- Nine patients with congenital, posttraumatic, or cleft-related midface retrusion underwent paranasal augmentation.
- Seven patients also had concurrent rhinoplasty.
- No implant-related complications were observed during a mean follow-up of 33 months (range 5-83 months).
Implications:
- Paranasal augmentation with porous polyethylene offers a viable alternative for correcting midface skeletal retrusion.
- Screw fixation ensures stable implant positioning and precise contouring, enhancing surgical outcomes.
- This technique avoids altering dental occlusion, a significant advantage in reconstructive surgery.
