The face of surgeries for the treatment of obstructive sleep apnea syndrome has changed over the years. Skeletal surgeries that implement maxillomandibular advanvement (MMA) - once used only after previous surgical approaches that have had limited success, such as pharyngoplasty, uvulopalatopharyngoplasty, etc.,- have now been applied as the first treatment alternative or even in conjunction with soft tissue surgery in many cases. There is mounting evidence that MMA is the most successful surgical treatment for OSAS. However, MMA through traditional surgical-orthodontic treatment comprises a pre-surgical orthodontic stage, which might not be adequate unless the patient uses a CPAP. A surgery-first approach eliminates orthodontic preparation for orthognathic surgery. This lecture will cover the diagnosis and MMA treatment planning for OSAS under the light of the 17-year clinical experience with surgery first approach.

1. After this lecture, you will be able to understand that leep apnea is a serious disease and orthodontics is part of the solution.
2. After this lecture, you will be able to recognize that conventional preparation for orthognathic surgery is inadequate for OSA patients
