Summary
This study introduces a modified chin implant technique to address bone resorption concerns. The modified implant and surgical approach show promise in augmenting microgenia while potentially mitigating resorption risks.
Area of Science:
- Plastic Surgery
- Biomaterials Science
Background:
- Bone resorption secondary to alloplastic chin implants is a significant clinical concern.
- Previous augmentation metoplasty techniques have raised concerns regarding implant-related bone loss.
Purpose of the Study:
- To describe a modified surgical technique and implant design for augmentation metoplasty.
- To evaluate the safety and efficacy of the modified chin implant in patients with microgenia.
Main Methods:
- A modified Safian's solid silicone implant with triangular wedges and silicone sponge augmentation was used.
- Twenty-five patients with moderate to severe microgenia underwent intraoral augmentation metoplasty.
- Implants were inserted with the central body supraperiosteal and lateral extensions subperiosteal.
Main Results:
- Two of 25 implants were removed due to postoperative infection.
- Nine patients were followed for 1-3 years with serial xerographic analysis.
- No specific results on bone resorption were detailed in the provided abstract.
Conclusions:
- The modified chin implant technique offers an alternative for augmentation metoplasty.
- Further long-term studies are needed to fully assess bone resorption and implant stability.
