Mandibular deficiency syndrome. II. Surgical considerations for mandibular advancement.

Eight factors which contribute to the successful surgical correction of the deficient mandible have been briefly discussed. Consideration of the recommendations made will permit surgeons to avoid pitfalls, regardless of the specific surgical technique used to advance the mandible, and will result in improved treatment results. The type of mandibular deficiency syndrome and its severity will dictate which factors need to be considered in a given case. A modified sagittal osteotomy is described as our preferred surgical technique to achieve these objectives and minimize untoward sequelae.
