Patients who have a maxilla that is retruded or hypoplastic, or both, but who have a mandible of normal position and size, will have degrees of flatness in the middle third of the face. Using systematic clinical evaluation and cephalometric skeletal analysis, a clinically recognizable facial deformity manifested by retrusion or hypoplasia, or both, of the maxilla, anterior zygoma, and infraorbital rims has been recognized. This deformity has been classified as infraorbital maxillary deficiency. The purpose of this paper is to describe an infraorbital-maxillary osteotomy for correction of this dentofacial deformity and to give a rationale for its use. The design of this osteotomy is determined by the skeletal deformity and can be classified as either low or high. The objective is to produce simultaneously a functional occlusion and facial harmony. Two of eight cases corrected by this surgical treatment are described.
上颌后缩或发育不全，或两者皆有的患者，若下颌位置和大小正常，则面部中三分之一会有不同程度的扁平。通过系统的临床评估和头影测量骨骼分析，一种临床上可识别的面部畸形已被确认，其表现为上颌、前颧骨和眶下缘后缩或发育不全，或两者皆有。这种畸形已被归类为眶下上颌骨缺损。本文的目的是描述一种用于矫正这种牙颌面畸形的眶下上颌骨截骨术，并给出其使用的理论依据。这种截骨术的设计由骨骼畸形决定，可分为低位或高位。目标是同时实现功能性咬合和面部和谐。本文描述了通过这种手术治疗矫正的八例病例中的两例。
