Mandibular distraction osteogenesis versus sagittal split ramus osteotomy in managing obstructive sleep apnea: A randomized clinical trial.

Purpose: To compare mandibular distraction osteogenesis (MDO) to sagittal split ramus osteotomy (SSRO) to treat moderate-to-severe obstructive sleep apnea (OSA), and their surgical morbidities and skeletal stability.

Materials And Methods: A randomized clinical trial was conducted on non-syndromic adult patients with apnea-hypopnea index (AHI) 15 or above to receive MDO or SSRO as part or whole skeletal advancement surgery. Post-operative 1 year OSA cure rate (AHI < 5/hour) and treatment success rate (50% reduction of AHI and AHI< 20/hour) were compared.

Distraction osteogenesis as a treatment of obstructive sleep apnea syndrome: A systematic review.

Background: To conduct a systematic review to answer the clinical question "What are the effectiveness of mandibular distraction osteogenesis (MDO) and its complications to treat patients with obstructive sleep apnea syndrome (OSAS)?".

Methods: A systematic search including a computer search with specific keywords, reference list search, and manual search were done. Relevant articles on MDO were assessed and selected in 3 rounds for final review based on 5 predefined inclusion criteria and followed by a round of critical appraisal.
