Recently Distraction Osteogenesis (DO) has been used successfully for advancing maxilla and mandible to treat sleep disordered breathing like Obstructive sleep apnea and non apneic snoring. Prime advantage of DO is slow stretching of soft tissues and bone formation allowing greater advancement and enhancement of airway volume.
10 cases with sleep disordered breathing due to maxillo-mandibular discrepancy of varying age groups were treated by various DO techniques. All the cases showed gross improvement not only in facial and dental aesthetics but also respiratory symptoms. A mean increase of 5.14 mm and 1.85mm with respect to posterior airway space and retro palatal space was observed in mandibular corpus lengthening cases. All the cases showed improvement subjectively and objectively.
DO has been found to be valuable and gives us the ability to both prevent and correct the development of sleep disordered breathing.
