Flat foot caused by talipes valgus can be evaluated by footprint in static state, while the development of bones of foot and the constitution of instep can be monitored on the lateral X-rays in weight loading.

足印图可对患儿足外翻引起的足扁平程度作静态评价，是一种粗略筛选方式；负重侧位X线片可观察患儿足部骨骼发育情况及负重时内、外侧纵弓的形态结构。

Results 22 patients underwent zygoma reduction and subperiosteal rhytidectomy by coronal incision approaching. 5 cases with frontal region depression were filled with ePTEF or a piece of epicranial aponeurosis. The follow-up time was 6～24 months. All the patients were satisfied with the final results.

结果：本组22例患者，均行头皮冠状切口颧骨颧弓复合体缩小及骨膜下除皱术，部分患者以膨体聚四氟乙烯补片或帽状腱膜行中上面部凹陷填充，术后面部软组织及骨性结构均得到显著的年轻化改善效果，随访6～24个月，面部外观满意。

The necessary lordotic alignment can be determined through careful review and analysis of the lateral

术前应该通过仔细阅读和分析侧位站立位X线片来确定脊柱前凸曲度，并估计合适的GSS III椎弓根螺

Methods: Fifty-fix adolescents were chosen and divided into first premolar extraction and nonextraction groups, with 30 and 26 patients respectively. The pretreatment and posttreatment panoramic radiographs were taken. The indexes of third molar eruption space, distance from third molar to occlusal plane and the length of mandible were measured and analyzed.

选择56例上下颌第三磨牙均存在的患者进行方丝弓正畸治疗，按照第一前磨牙拔除与否分为拔牙组（30例）和非拔牙组（26例），利用术前术后曲面断层片对患者上下颌第三磨牙萌出间隙、第三磨牙与胎平面的距离以及下颌长度进行测量分析。

Methods The characteristics of soft and hard tissues of 15 patients were analyzed by studying lateral cephalometric radiographs and plaster model,then the mechanism of malocclusion was probed and the scheme of treatment was formulated,the malocclusion was treated by edgewise appliance after extracting bilateral maxillary first bicuspids.

15名患者通过头颅定位侧位片与记存模型，分析硬组织指标、软组织面型特征，探讨错牙合机制，制定矫治方案，减数拔除双侧上颌第一双尖牙齿，采用方丝弓矫治器进行矫治。

Methods 13 Angle Ⅱ 1 cases were choses as study sample (average age was 24.3 ) and treated with Tip Edge appliance.

对13例平均年龄为 2 4.3岁的成人安Ⅱ1类错牙合患者治疗前后用Tip Edge差动直丝弓技术进行诊疗，并于头颅侧位片。

Compare the radiographic and clinical outcomes of adult spinal deformity patients treated with thoracic pedicle screw or thoracic hook constructs.

目的：对**脊柱畸形分别采用胸椎弓螺钉或钩固定，比较它们在平片和临床结果的区别

To understand the role of tongue in the development of occlusion, the relationship between tongue movements during swallowing and dentofacial morphology was examined by ultrasonography, cephalometric radiography and dental casts.

为了了解舌头在咬合发展所扮演的角色，本实验使用超音波、传统测颅X光片及牙弓模型为测量工具，检测舌头吞咽功能与齿颜面形态的相关性。

Furthermore, routine evaluation of patients' status post pedicle screw fixation can be reliable obtained with radiographs.

此外，X片可以作为评价椎弓根螺钉固定术后患者情况的可靠的常规手段。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
