Use of a titanium cutting guide to assist raising the composite radial forearm free flap

The use of composite radial free tissue transfer has been overtaken by other composite flaps. This is due to donor site morbidity and the poor volume of bone yielded. The advantages and potential complications of composite radial flaps are well described. Use of the composite radial forearm free flap has been largely superseded in mandible reconstruction, but applications such as a salvage option still exist. Additionally it may be used in the reconstruction of midface defects. The use of a cutting guide to reduce the donor site complications and yet produce a maximal yield of bone is described herein. With the use of a skilled maxillofacial laboratory, the planning allows precise cuts and placement of the free flap and allows accurate prophylactic plating of the radius. A precise titanium cutting guide and custom distal radius plate are used. Details of three cases where these techniques have been implemented are described. The paper demonstrates the significant advantages of using laboratory-based technology to assist in performing composite radial free flaps. This paper reveals that composite radial free tissue transfer still has a place in the reconstruction of very selective defects of the head and neck. In particular, its use in reconstruction of Class 5 and 6 maxillary defects (Brown classification) is illustrated. Correct case selection and planning results in increased confidence to use this flap.
