Summary
The W-shaped (
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Surgical Anatomy
Background:
- High labial incisions in genioplasty are associated with improved scar outcomes compared to conventional deep labial approaches.
- Optimizing surgical access and visibility is crucial for successful genioplasty and chin osteotomies.
Purpose of the Study:
- To prospectively compare the efficacy of high labial curvilinear incisions versus W-shaped ('royal') incisions for access and visibility during chin osteotomy.
- To evaluate wound area and potential complications associated with each incision type.
Main Methods:
- A prospective randomized trial involving 18 high labial curvilinear incisions and 27 high labial W-shaped incisions.
- Measurement of maximal incision lengthening and wound area to assess surgical access and visibility.
- Documentation and comparison of complications between the two groups.
Main Results:
- No significant difference was found in maximal incision lengthening between the curvilinear and W-shaped incisions.
- The W-shaped incision group demonstrated a significantly larger mean wound area (188.75 mm2, P < 0.001), indicating superior access and visibility.
- Complications were minimal in both surgical groups.
Conclusions:
- The high labial W-shaped ('royal') incision provides superior access and visibility for genioplasty and chin osteotomies compared to the curvilinear approach.
- The W-shaped incision is recommended for complex chin osteotomies and ostectomies, while a smaller curvilinear incision is suitable for simple advancements.
