Mandibular Body Resection and Setback for Severe Malocclusion in Lymphatic Malformations

Extensive lymphangiomas of the facial skeleton result in deforming forces leading to ongoing masticatory, speech, oral hygiene, and airway problems. This paper presents a small series of patients with severe mandibular overgrowth secondary to lymphatic malformations. Following debulking of the malformations and tongue reductions, the authors describe the results of their treatment with bilateral mandibular body resections and setback. The authors' results suggest that severe functional impairment from deforming malformations can be addressed in childhood with orthognathic surgery. Improved occlusion, oral closure, and airway opening can be achieved using this procedure.
