Currently, the number of obstructive sleep apnea (OSA) patients has been increasing. OSA can be life threatening if it is not treated. The clinician can perform either conservative or surgical treatment. Treatment choice depends on several factors, such as OSA severity, patient needs, and the advantages and limitations of each treatment.

However, this approach has disadvantages, such as the associated risks and cost. This review article presents an overview of MMA, including its effect in treating OSA, facial profile changes, complications, and stability after MMA.
