Cohn stock []wassmund []wunderer []cupar [], 1955bell [12, 13]epker []to shift the protruded anterior maxillary alveolar process backward, a wedge shaped or rectangular bone block is removed from the alveolar process—in principle analogous to segmental osteotomies in mandibular protrusion—and then the anterior premaxillary segment is mobilized by a supra apical osteotomy and moved backward.
Segmental Maxillary Osteotomies In Conjunction With Bimaxillary Studies have reported relapse rates for maxillary superior repositioning of the maxilla ranges from a mean of 0–18% for the anterior maxilla and 6–7% for the posterior maxilla. relapse rates for maxillary advancement range from 5 to 15%. as with most orthognathic surgery, relapse is greater with increase in the maxillary advancement. 1. revise the osteotomy cuts at all accessible sites, includ . ing anteromedial antral, lateral antral, and superior nasal. crest. 2. the maxilla may be “hinged down” to directly visual. ize.

Abstract. this chapter describes the techniques for segmental surgery undertaken in conjunction with the le fort i maxillary osteotomy with an outline of the historical procedures. among the well established indications for undertaking segmental maxillary surgery are the management of an anterior arch length discrepancy and a narrow maxilla.
