  • Title: The surgical correction of vertical maxillary excess (long face syndrome).
    Author: Angelillo JC, Dolan EA.
    Journal: Ann Plast Surg; 1982 Jan; 8(1):64-70. PubMed ID: 7073194.
    Abstract:
    The surgical correction of vertical maxillary excess is a relatively new technique. Vertical maxillary excess (VME) may exist alone or in combination with a horizontal mandibular deficiency with or without an anterior open bite. The facial contour is characterized by a long, tapering face with anterior and posterior maxillary overgrowth, a narrow alar base, and lip in competence. Cephalometric analysis demonstrates steep mandibular and occlusal planes in relationship to the cranial base, and increase in facial height, and retroposition of the mandible. Evaluation of study models exhibits increased alveolar bone height, a high palatal vault, and a narrow maxillary arch. The dental relationship may be Class I, II, or III, with Class II being the most common. Orthodontic treatment before surgery consists of correct alignment of the teeth and removal of those dental compensations that preclude good dental interdigitation at surgery. Regardless of the surgical procedure, accurate preoperative planning based on careful evaluation of skeletal, dental, and soft tissue features in conjunction with correct orthodontic surgical sequencing is the key to a satisfactory result. The "downfracturing" or Le Fort I maxillary osteotomy for superior repositioning of the maxilla is the surgical procedure of choice for vertical maxillary excess. Two-, three-, or four-segment maxillary osteotomies can be done in conjunction with the Le Fort I osteotomy without jeopardizing healing capacity.
