Plastic and Reconstructive Surgery
|September 1, 1986
Summary
A new technique transfers vascularized outer-table calvarial bone for craniofacial reconstruction. This method shows remarkable stability and minimal resorption, making it ideal for challenging recipient sites.
Area of Science:
- Plastic Surgery
- Anatomy
- Biomedical Engineering
Background:
- The calvarium's vascular supply is crucial for bone graft survival.
- Existing methods for craniofacial reconstruction face challenges with graft resorption and vascularity.
Purpose of the Study:
- To describe a novel technique for harvesting and transferring vascularized outer-table calvarial bone.
- To evaluate the efficacy of this technique in craniofacial reconstruction.
Main Methods:
- Anatomic study of calvarial vascularization in cadavers.
- Development of a surgical technique utilizing the periosteum and innominate fascia.
- Clinical application in 37 craniofacial reconstructive cases.
Main Results:
- Successful transfer of vascularized outer-table calvarial bone flaps.
- Demonstrated remarkable stability of the bone grafts.
- Observed minimal resorption in the reconstructed areas.
Conclusions:
- Vascularized outer-table calvarial bone transfer is a reliable technique for craniofacial reconstruction.
- This method is particularly advantageous in poorly vascularized or infected recipient beds.
- The technique offers superior stability and reduced resorption compared to traditional methods.
