小下颌

The skeletal system showed a series of evolutive characteristics, for example, it had one premaxillary and one frontal bone, the malaris disappeared, the squamosal became smaller, the vomer became thinner, the suturae between the dentary and splenial and the suturae between the coronoid and angular was blurry.

表现出了一系列进化特征，如前颌骨愈合成1块，额骨也愈合成1块，颧骨消失，鳞骨变小，犁骨薄弱，下颌夹板骨与齿骨、冠状骨及隅骨之间的骨缝不明显，愈合程度较高。

The mouth openings of 58 cases were over 37 mm, only 4 cases less than 37 mm in 3 months postoperatively. Conclusion: The miniplate internal rigid fixation has the advantages over conventional intermaxillary fixation and wire fixation

下颌骨骨折的小型钛板坚固内固定效果可靠，避免了颌间结扎；对颞下颌关节功能影响小；口内手术入路避免了面部皮肤瘢痕；较传统的下颌骨骨折颌间结扎固定及钢丝拴扎固定有明显的优点。

Skull long after the short articular process, the Department of the mandibular joint high mental process but a very small or non-development, these characteristics and Pap is very close to saber-toothed tiger.

长头骨后关节突短，下颌联合部很高但颏突很小或不发育，这些特征与巴氏剑齿虎十分接近。

The largest one of these tumors had a diameter of 16cm which occurred at parotid,and the smallest one occurred at buccal gingiva of the left submaxilla had only 0.8cm.

此外 ，多形性腺瘤的体积，最大的直径为 16cm发生在腮腺，最小的约为豌豆大小(0 8cm)发生在左下颌颊侧牙龈部。

Key words: tempromandibular joint ankylosis; arthroplasty; micrognathia; sagittal split ramus osteotomy; genioplasty

颞颌关节强直；关节成型术；小颌畸形；下颌升支矢状劈开截骨术；颏成形术

Methods For gain optimal operation outcome,we used prolong carved mandible angle osteotomy by intraoral approach.we extended osteotomy line to mental nerve.and mental tuber was scoured,Augmentation chin or genioplasty was performed if the patient was subject to microgenia.

为获得更好的术后效果，我们采用口内入路下颌角弧形截骨术，将弧形截骨线延长到颏神经处，并对颏结节进行打磨，使截骨线延续流畅，伴小颏者同时行隆颏或颏截骨前移。

The face is paralytic can happen at all ages, but 15~45 year old the commonnest, come on the peak is reached inside over number hour or 1~3 D, can incline the head unhealthily at the beginning of disease or ache after mandible horn, expression breaks down for flesh of a side countenance, frontal grain disappears, the eye is cracked greaten or close faint, when closing a key point, eyeball up foreign and rotational, show white sclerotic, call Bell the phenomenon, channel of ill side nose lip becomes shallow, quarrel prolapse, side of crooked Xiang Jian of the quarrel when grinningly, rouse cheek or whistle hourglass is enraged, the food when taking food often stops to age at ill side buccal between, at the same time companion has weep reach salivate.

面麻痹可发生于所有年龄，但15~45岁最常见，发病多于数小时或1~3 d内达到高峰，病初可有病侧耳或下颌角后疼痛，表现为一侧面部表情肌瘫痪、额纹消失、眼裂变大或闭合无力，闭眼时，眼球向上外方转动，露出白色巩膜，称Bell现象，病侧鼻唇沟变浅，口角下垂，露齿时口角歪向健侧，鼓腮或吹口哨时漏气，进食时食物常滞留于病侧齿颊之间，同时伴有流泪及流涎。

Results Different signs of the lesions were demonstrated on X-ray plain film, such as locular,rough of bone trabecula and soap bubble-like changes ,frequently accompanied by dilatation of the mandibular nerve canal.

结果颌骨高流速血管畸形在X线平片上呈现多种表现，如囊状、骨小梁粗糙及&皂泡样&改变，多伴下颌神经管的扩张

Objective To improve the efficacy of operation for patients with prominent mandibular angle along with chin microsomia.

目的：提高双侧下颌角肥大伴有小颏畸形的手术治疗效果。

Results:When wide-diameter implant or two-implant were used to replace single mandibular molar, the stress of implant-bone interface was much lower than that of standard-diameter implant restoration. Comparison between wide-diameter implant and two-implant replacement showed that the former created lower stress. The difference was more obvious under oblique loads.

结果：与单个标准直径种植体修复相比，采用单个大直径种植体或双种植体修复单个缺失下颌磨牙均可使种植体-骨界面应力值大大降低；而采用单个大直径种植体修复单个缺失磨牙时骨界面应力值相对较小，以斜向加载时更为明显。

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。
