关节窝

Superior border in all 13 subjects treated with fixed inclined bite??plate. MRI??signs of glenoid fossa remodeling at anterior??inferior border of post??glenoid spine were noted in 2 of 13 subjects. Condylar??fossa relationship changes were unconspicuous before and after treatment.

结果： 13例患者MRI结果均可见到髁突后上部发生改建，有新骨形成的表现；2例可见到关节窝改建，位于关节后结节的前缘下方，治疗前后髁突在关节窝中位置无明显变化。

Sometimes can hear clear and crisply play sound when the pulley returns to joint nest.

有时在滑车回关节窝时能听到清脆的弹响声。

Objective: To quantify the new bone formation in the glenoid fossa of the temperal bone in response to the mandibular advancement.

目的：定量分析大鼠下颌持续前伸对颞下颌关节窝新骨形成的影响。

Sections were cut through the glenoid fossa at the sagittal plane and stained with PAS under the same condition.

结果：大鼠在下颌持续性前伸条件下，其颞下颌关节窝后份有明显的新骨沉积。

Postoperative MRI showed that the joint space filled with mixed-signal material, the condyle and glenoid fossa were completely separated.

术后MRI显示，髁突与关节窝之间均山混合信号物质充填，两者完全隔开。

There is significant subluxation present where the ball is partly or completely out of a shallow socket.

股骨头部份或完全脱出关节窝而形成脱臼的状况。

Most perforated cases were located in the bilaminar and post band of disc and there were synovial hyperplasia, fibrillation, fibrocartilage rupture,and bone exposure.

关节盘穿孔大多数位于双板区与后带。关节盘穿孔出现滑膜增生，关节窝及关节结节表面纤维形成，软骨剥脱甚至骨质暴露。

Based the above research, we chosen 48 cephalometric radiographs of skeletal classⅢocclusion (18-39 years old, ANB4°) and measured with computer assistant Delaire cephalometric analysis. The data were deal with ANOVA analysis through SAS9.0 statistical software. The research divided the cranio-maxillo-facial hard tissue structure feature of skeletal classⅢinto four classifications through Delaire cephalometric analysis including hypo-divergent, hyper-divergent, maxilla normal and glenoid fossa retrocession, nine parameters of four groups have significantly variability through ANOVA analysis(P.05),for example, anterior cranial base angle, sphenoidal angle, percentage of craniospinal area to cranial depth ,percentage of craniofacial area to cranial depth and so on.

在上述研究的基础上，首先选取48例骨性Ⅲ类错牙合畸形患者(18-39岁，ANB角4°)应用Delaire头影测量分析法进行测量，经SAS9.0行ANOVA分析，将骨性Ⅲ类错牙合畸形区分为低角型、高角型、上颌正常型和关节窝后移型四组，四组均数ANOVA分析发现九项分析指标的均数差异均有统计学意义(P.05)，如蝶鞍角、前颅基底角、颅面区比和颅颈区比。

METHODS: Oblique sagittal T1 weighted MR imaging at closed mouth was obtained from 88 joints of 44 patients who complained of unilateral TMJ pain. On MRI view, a straight line AE was drawn through the lowest point of articular eminence and the highest point of external auditory meatus, and then the perpendicular lines were dropped from condylar head and the most poterior band of the disc to AE on which the cross points were marked as C′ and D′.

关节盘移位程度的测量方法：MR成像层面上关节结节最下点到外耳道最上点的连线为直线AE，髁突顶点及关节盘最后点与直线AE垂直相交点分别为C′、D′，分别求得AD′距离、C′D′距离，代表关节盘在关节窝前后方向的位置。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
