Calvarial bone graft harvest: a new technique
1Department of Otolaryngology-Head and Neck Surgery, University of California, Davis, Sacramento, CA 95817, USA.
Summary
The new calvarial bone graft-harvesting device (BHD) offers a safe and efficient method for obtaining bone grafts. This study demonstrates its effectiveness in harvesting calvarial bone grafts (CBGs) for reconstructive surgery.
Area of Science:
- Neurosurgery
- Plastic and reconstructive surgery
- Biomedical engineering
Background:
- Calvarial bone grafts (CBGs) are valuable for craniofacial reconstruction.
- Traditional harvesting methods using osteotomes or saws can be time-consuming and may lead to graft complications.
- A novel bone graft-harvesting device (BHD) was developed to improve efficiency and safety.
Purpose of the Study:
- To evaluate the safety and efficiency of a new calvarial bone graft-harvesting device (BHD).
- To assess the quality and usability of calvarial bone grafts (CBGs) harvested with the BHD.
Main Methods:
- Eighteen calvarial bone grafts (CBGs) were harvested from cadavers using the BHD.
- Parameters recorded included drilling time, harvest time, graft dimensions, integrity, and inner table violation.
- Five CBGs were harvested in vivo and utilized for nasal and orbital reconstructions.
Main Results:
- CBG dimensions varied, with lengths up to 16.0 cm.
- Graft harvest time averaged 13 minutes and 7 seconds.
- No grafts were fractured; minor inner table violations occurred in 2 cadaveric specimens, and one dural exposure occurred in vivo.
Conclusions:
- The BHD is a safe and efficient tool for harvesting calvarial bone grafts (CBGs).
- It demonstrates potential advantages over traditional osteotomes and oscillating saws.
- Further clinical application is supported, with appropriate precautions.
