Various lesions are treated in the oral maxillofacial regions such as jaw cysts, benign and malignant tumours, mucous diseases, maxillofacial fractures, congenital discorders of cleft lip and palate, facial deformities and temporo-mandibular disorders. The large amount of data which includes X-ray, computed tomogram (CT), magnetic resonance image (MRI) and so on, has been accumulated to diagnose and follow up for prognosis of patients. It is impnd and urgent not only for clinical studies and education, but also for patients to make the best use of important and multiple information and feed back clinically.With the dedatabase system for dento-facial deformities, contributing factors to postoperative relapse in simultaneous surgery of maxilla and mandible were investigated by a multiple stpwise regression analysis. Cephalograms were randomly traced and measured in the radiographic landmarks to obtain a consistent sell-nasion. The landmark points and angles were as follows : 1. Point A ; … More horizontal distance AX and vertical distance AY,Point B ; horizontal distance BX and vertical distance BY,U1 : U1.X and U1Y,L1 ; L1X and L1Y,Pogonion ; Pog.X and Pog.Y,SNA,SNB,P P and M P.Results.The average postsurgical change is 4.5mm in vertical advancement of point A (Apoint.X), and 11.4mm in vertical setback of Pogonion (Pog.X).At 1 year postsurgery, point A has the tendency to upward movement, while the change degree at point B and Pogonion are larger than that of point A.From these mesurements and statistical data with cephalogram, main contributing factor to point A relapse after surgery was investigated by multiple stepwise regression analysis. As the many variables, predictable factors were assessed acording to the degrees of partial correlation and simple correlation. The main factors to influence on relapse at point A result in the vertical and horizontal movement at L1 and Pogonion, also angle change at mandibular plane at surgery. Otherhand, postsurgical vertical and horizontal movements at point B cause unstability at surgical site of maxilla. Less

治疗口腔颌面部的各种病变，如颌骨囊肿、良性和恶性肿瘤、粘膜疾病、颌面部骨折、先天性唇腭裂、面部畸形和颞下颌关节疾病。目前已积累了大量的X线、CT、MRI等影像学资料，用于诊断和随访患者的预后。本文利用建立的牙颌面畸形数据库系统，对影响上下颌同期手术后复发的因素进行了多因素逐步回归分析。随机追踪和测量X线标志的头颅骨X线片，以获得一致的鞍鼻根点。标志点和角度如下：1。A点; ...更多信息 水平距离AX和垂直距离AY，点B ;水平距离BX和垂直距离BY，U1：U1.X和U1 Y，L1 ; L1 X和L1 Y，Pogonion ;结果：术后A点垂直前移平均4.5mm（A点X），小刺的垂直缩进为11.4mm（Pog.X）.术后1年，A点有向上移动的趋势，而B点和Pogonion点的变化程度大于A点。采用多元逐步回归分析，探讨影响A点复发的主要因素。由于变量众多，预测因子按偏相关和简单相关程度进行评价。影响A点复发的主要因素是L1和颏部的垂直和水平运动，以及术中下颌平面角度的变化。单手、术后B点的垂直和水平运动导致上颌骨手术部位不稳定。少
