Results Among 38 cases,16 cases received surgical treatment within 2448 hours,and 22 cases received surgical treatment 32129 days after trauma with other causes.Thirtyfive cases were cured and decannulated except 3 cases with laryngotracheal stenosis failed in decannulation.All cases with acute trauma were decannulated.

结果 38例中16例急性喉外伤在24～48小时之间行手术治疗，22例陈旧性喉外伤因其它原因在32～129天后行手术治疗。35例手术成功拔管，3例因喉气管狭窄手术失败不能拔管，均为陈旧期手术患者。

The difference is releasing and letoff unit vector pond?athis, and the feeding frequency conversion motor traction and the traction unit takes a servo motor.

所差别的是不播卷和播卷单位拔取了互换矢量变频电机，而进料牵引和不入料牵引单位却拔取了伺服电机。

Carving To resolve this issue, Hell and Daetwyler-Ohio the company's technical staff with some methods, such as Daetwyler-Ohio the company's TransCell technology in sculpture at the time of produce…… geavier xuetie microamounts change the net amount of white space to make it smaller, local space between the machinery space, carving resolution; Hell from the knife is microdose mobile, similar to "anti-moism technology" a way for small network points added in geavier of histologicai gap, pactbe from the Visual effects.

为了处置这个题目，Hell和Daetwyler-Ohio公司的技艺职员拔取功一些办法，例如Daetwyler-Ohio公司的TransCell技艺在雕镂笔墨的笔划时微度保持网穴的间距，使其间距变小，部分不天增增雕镂不分辨率；Hell公司不兴雕镂刀的微度安放边，还拔取近似&不侧澄清技艺&的办法，用小网穴赔偿在笔划的锯齿空不天处，从触觉成果上赐与填充。

In the peacetime, the bactria results in of the chronic infection will make gum inflammation, easily bloodshed, palatine bone absorption, decayed tooth and toothache, end because dens turnover get sick of tooth loose move or dens neurapophysis necrosis and pull out a tooth, next door usefully the second molar teeth be usually also subjected to spread and result in at this time the injury of waiting the degree even pull out a tooth not, this is also the most regrettable place.

在平时，细菌造成的慢性感染会使牙龈发炎，容易流血，骨吸收，蛀牙及牙痛，最后因牙周病的牙齿松动或牙髓坏死而拔牙，这时隔壁有用的第二大臼齿往往也会受到波及而造成不等程度的伤害，甚至拔牙，这也是最可惜的地方。

Between extraction and nonextraction group, there are significant difference. Conclusion Howes'method is instructive for orthodontic treatment.

采用Howes法评估牙弓骨量与牙量对正畸临床的诊断和拔牙与非拔牙矫治设计有一定的指导意义。

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。

Meta analysis was used to comprehensively quantitatively analyze the upper lip with esthetic plane and soft tissue plane before and after extraction and nonextraction treatment. According to homogeneity test, fixed effect model and random effect model were adopted to calculate weighted mean difference and 95% confidence interval (95% CI).

运用meta分析技术对拔牙与非拔牙矫治前后上下唇与审美平面及软组织平面的距离进行综合定量分析，根据资料异质性检验，采用固定效应模型及随机效应模型，计算合并加权均数差及其95%CI。

Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

应用PAR 指数对矫治前后的143 副恒牙早期的安氏Ⅱ类1 分类错牙合患者牙牙合模型进行评估分析，按矫治结果等级分为三类A、变坏或无改善，B、改善，C、极大改善，然后将B、C 两类患者矫治前的头影测量片及模型分析数据按拔牙与未拔牙进行成组t 检验的单因素分析，找出两组间有显著差异的软硬组织和牙牙合模型指标，对这些指标合并年龄因素进行逐步判别分析。

A discriminate function, Z=0.952X_1 +0.591X_2(U1-Apgmm)–0.430X_3 was produced by multiplefactorial discrminate analysis. Z≥0 is an indication of extraction ,and Z is anindication of nonextraction on the other side.

将这些指标通过逐步判别分析得出的判别方程为：Z=0.952x_1+0.591x_2(U1-Apgmm)-0.430x_3，有助于这两种治疗方法的选择，Z≥0时，拔牙的可能性较大，Z﹤0时，不拔牙的可能性较大。

Pull outPull out = take out, produce; drive (= take out, produce; drive

outout 表示表示&&拔出，抽出，取出；驶拔出，抽出，取出；驶
