Distraction Osteogenesis versus Bilateral Sagittal Split Osteotomy: A Systematic Review Comparing the Skeletal Stability and Post-Operative Complications.

BACKGROUND

The most commonly used surgical technique for retrognathic or hypoplastic mandible is "Bilateral Sagittal Split Osteotomy (BSSO)". Distraction Osteogenesis (DO) can be used for mandibular advancements of 10 mm or more and has been stated to be stable.

OBJECTIVES

The purpose of this study was to know whether there is any difference between "Bilateral sagittal split osteotomy" (BSSO) and "Distraction osteogenesis" (DO) in the advancement of mandible in terms of stability and their post-operative complications.

RESULTS

Out of five selected studies, there was a statistically noteworthy difference between "BSSO" and "DO" in terms of NSD of IAN function. There was also a statistically marked difference between BSSO and DO in terms of condylar resorption and post-operative infection.

CONCLUSION

DO has reduced the incidence of neurosensory disturbance of IAN as compared to BSSO.
