Methods 43 cases of lumbar stenosis undergone domelike decompression were performed L(subscript 3~4) and L(subscript 4~5) CT scanning pre-and postoperatively.

对弯顶形椎管扩大成形术治疗的43例腰椎管狭窄症患者手术前后进行CT扫描，用Image-Pro软件对CT扫描片进行椎管L(下标 3~4)、L(下标 4~5)的椎管矢径、上关节突内缘间距、椎板间距、截面积测量分析。

Domelike decompression can increase APDC, IFD, ELD and CSAC significantly, especially for CSAC, which is an effective way for lumbar stenosis.

弯顶形椎管扩大成形术可明显扩大腰椎管的矢径、上关节突内缘间距、椎板间距和椎管截面积，尤其是椎管截面积扩大更为明显，是一种治疗腰椎管狭窄症有效的方法。

Transversal planes through thorax and sagittal plane done at 30 week of pregnancy, showing cystic mass located in left dorsolateral portion of the thorax.

孕30周经胸腔的横切面和矢状面显示位于胸腔左背外侧的囊性团块。

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。

Under the fluoroscopic guidance, the glenohumeral joint was punctured, and 15-20ml of a mixed contrast solution (22%Omnipaque and 3mmol/L Magnevist) was injected inside the joint. Then SE T1-weighted sequence (repetition time/echo time=500 ms/20 ms) was performed in oblique coronal, oblique sagittal and axial plane within 45 minutes.

在透视下穿刺肩关节腔，注入15～20ml 22％ Omnipaque和3mmol/L Magnevist的混合性造影剂，然后在45分钟内完成SE序列T1加权(TR/TE=500/20ms)的斜冠状面、斜矢状面和横断面MR成像。

Measures could be adopted in the design are introduced in this article by calculating and analyzing the ellipse flat arch bridge from two engineering examples and comparing the differences between two hinged arch and hingeless arch in different rise-span ratio.

结合工程实例，对椭圆轴线坦拱进行计算分析，比较了不同矢跨比情况下两铰拱、无铰拱的区别，介绍了在设计中采取的措施。
