Bone graft in bilateral mandibular sagittal split osteotomy: the current state of practice in France

Introduction

Bilateral sagittal split osteotomy of the mandible (BSSO) is the most common orthognathic surgery procedure. The use of bone grafting seems widely used whereas its interest has not been shown to date. The aim of this study was to describe the current state of practice of bone graft in BSSO in France.

Materials and methods

An online survey was used to collect data about the use of bone grafting in BSSO procedures among French maxillofacial surgeons.

Results

One hundred and forty-eight surgeons responded to the survey, mostly maxillo-facial surgeons (96 %). Only 31.8 % of participants had already performed grafts in BSSO and the majority did it in less than 10 % of cases. The main grafting indication was the degree of advancement especially for advances over 10 mm. Different types of grafts were used, mainly: autologous bone grafting (mandibular or hip) or other bone grafting (xenograft, allograft).

Conclusion

This survey shows the diversity of practices in France regarding the use of grafting in BSSO. Further studies are needed to investigate prospectively the utility of such procedures.
