METHODS: From April 1998 to February 2002, 12 patients with micromandibular deformity associated with OSAS (aged 14-36 years, 7 females and 5 males) were treated. Invert "L" shape ramus osteotomy and inverted replantation of posterior segment of ramus were performed to reconstruct the TMJ with the jaw advancement and genioplasty at the same time in 7 cases; mandibular angle osteotomy, bone grafts and genioplasty in 3 cases; and the jaw advancement by ramus sagittal osteotomy and genioplasty in 2 cases of the first branchial arch syndrome. RESULTS: The follow-up period was 6 months to 4 years.

1998年4月～2002年2月，对12例(女7例，男5例，年龄14～36岁)伴有严重OSAS症状及张口度0～3.0 cm的小下颌畸形患者，7例采取下颌升支倒&L&形截骨、升支倒置颞下颌关节重建术的同时施行下颌体部前徙和颏成形术；3例在颞下颌关节重建术后进行下颌角部截骨、植骨下颌骨前徙术；2例施行下颌升支矢状劈开、下颌骨前徙术。

Cases underwent bilateral TMJ reconstruction, bone graft and genioplasty in order to advance the jaw. Bimaxillary surgical procedure was completed in 3 cases, and distraction osteogensis and TMJ reconstruction in 6 cases. Al patients gained good appearance, 29 patients can open their mouth larger than 3 cm, and one case had recurrent TMJ ankylosis. 29 cases'AI＜5 and oxygen saturation degree ＞90%(included the patient that had recurrent TMJ ankylosis).

结果 本研究有15例患者接受患侧下颌升支倒置TMJ重建、植骨前移，健侧升支矢状劈开、下颌前移和颏前移成形术；其中有3例行二期的上颌的Le Fort Ⅰ截骨术。6例行双侧TMJ重建、植骨前移下颌和颏成形术。3例施行同期双颌截骨前移和颏成形术；6例行单或双侧TMJ重建、牵引成骨术。

We conclude that favorable results can be obtainedwhen either nerve stimulation or ultrasound guidance is usedfor lateral sagittal infraclavicular block.

我们得出的结论是无论是用神经刺激还是超声引导来进行侧位矢状面的锁骨下阻滞都能取得良好的结果。

Results: The thickness of intertransverse ligament was about 0.60~1.39mm.

结果：横突间韧带厚度0.60~1.39mm；L(下标 3-5)节段动脉前支及伴行静脉90%以上位于相邻横突间韧带腹侧上1/2处，横突间韧带背侧中1/3处有一恒定节段动脉分支；腰神经前支与矢状面夹角18.90°~39.20°，下位横突的副突处距前方走行腰神经前支距离为5.63~8.05mm，椎弓峡部侧缘至腰神经前支的距离为1.73~3.64mm。

Figure 2. A, Parasagittal scan at right adnexa shows loculated fluid with several septations with echogenic nodular masses representing peritoneal thickening or omental thickening. B, Transvaginal scan of the left adnexa shows a poorly defined complex mass representing peritoneal or omental thickening.

图2 A，右侧附件区的矢状旁面扫描显示积液呈多房性，有数个分隔，结节性肿块表明腹膜增厚或网膜增厚。B，经阴道扫描显示左侧附件区边界模糊的混合性肿块，表示腹膜或网膜增厚。

Figure 2. A, Parasagittal scan at right adnexa shows loculated fluid with seeral septations with echogenic nodular masses representing peritoneal thickening or omental thickening. B, Transaginal scan of the left adnexa shows a poorly defined complex mass representing peritoneal or omental thickening.

This model may be applied for the study of morphologic characteristics and changes induced by growth,orthodontic treatment and orthognathic operation on middle sagittal plane.

该模型可用于颅颌面硬组织在正中矢状面上的形态特征及因生长、正畸矫治、正颌手术引起的形态变化研究。

From the analysis of three-dimensional finite element, we get the results that the horizontal-shaped fracture is more stable than the skewed fracture under the same condition in which fracture ends are full of poroma.

纵轴加压或拉伸对肢体远端的位移影响少，而水平轴和矢状轴方向尽管加载力较小，仍能产生肢体远端的较大位移。

The main changes were the downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors.FR-Ⅲ also promotes the growth of maxilla and reaches the normal relationship of the anterior overjet and overbite.

结果：FR-Ⅲ能矫正上下颌基骨异常的矢状关系，主要变化是下颌骨向下、向后旋转，改变下颌骨生长的方向，同时使下颌切牙舌倾、上前牙唇倾，上颌骨向前生长。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
