OBJECTIVE: @entity27 ( @entity27 ) can be a @entity74 to treat. Maxillomandibular advancements (MMAs) generally have high success rates; however, larger advancements have higher success and cure rates. Our aim is to present and to describe the current technique used by the senior authors, which has been successful for performing large advancements, thereby improving post-operative outcomes. METHODS: The senior authors have developed and modified their maxillomandibular advancement operative techniques significantly over the past 30 years. The current version of the Riley-Powell MMA technique is described in a step-by-step fashion in this article. RESULTS: Initially, as part of the MMAs, @entity1 underwent maxillomandibular fixation with wires, lag screws and harvested split calvarial bone grafts. The current technique utilizes plates, screws, Erich Arch Bars, and suspension wires which are left in place for 5-6 weeks. Guiding elastics are worn for the first week. The @entity15745 technique described in this article has yielded a success rate over 90% for @entity1 with a body mass index (BMI) <40  kg/m(2) and 81% for @entity1 with a BMI >= 40  kg/m(2). CONCLUSION: Large advancements during maxillomandibular advancement surgeries can help improve post-operative @entity27 outcomes.

Large maxillomandibular advancements for XXXX : An operative technique evolved over 30  years.
