Hemimandibular Elongation: Is the Corrected Occlusion Maintained Long-Term? Does the Mandible Continue to Grow?

In HME, a favorable occlusion can be reliably achieved and maintained long-term in most cases using standard bimaxillary orthognathic technique. The need for mandibular setback, even in the presence of simultaneous maxillary advancement, proved to be a factor in the recurrence of long-term posterior malocclusion, although the risk remains low. The results clarify that in patients with HME, by use of the described techniques and timing for surgery, there is no need for an ablative open joint procedure to arrest condylar growth.
