下颌角

Methods: Measuring the bone density of mandibular angle and coxofemoral region with dual energy X ray absorptiometer.

采用双能X线吸收测量仪，测量右侧髋部与左侧下颌角的骨矿物密度。

Results:The depth of the needle to block the glossopharyngeal nerve,showed as the distance between the mastoldale and jugular foramen,was 23.2±0.4 mm in left side and 23.0±0.4 mm in the right side.

结果：舌咽神经阻滞进针的深度：乳突尖端与下颌角之间连线的中点至颈静脉孔的距离，左侧为(23.2±0.4) mm(17.0～30.1 mm)，右侧为(23.0±0.4) mm(16.5～33.3 mm)。

RESULTS: The interobserver accuracy was 100% between observers for identifying the AM, hyoid bone, thyroid cartilage, and cricothyroid membrane, and 93% for carotid tubercle.

结果：用下颌角、舌骨、甲状软骨和环甲膜进行辨识，目标观察物的准确度为100%，颈动脉结节为93%。

There was 100% correlation between the position of the mandibular angle in the preoperative standing lateral radiograph and the intraoperative supine lateral radiograph, compared with 65% with the hyoid bone.

术前站立位颈椎侧位X线片与术中的仰卧位颈椎侧位X线平片之间下颌角位置的关联性为100%，相对应的是舌骨为65%。

Methods Milling-technique was used to change the lineament under local anaesthesia and through intraoral approach.

局麻下经口内入路，运用"铣骨技术"对下颌角肥大、下颌骨斜线部位增生、颧弓过高等情况进行处理。

Postoperative follow up for 1～36 months showed satisfactory results in all cases.conclusionthe abrasive osteoplasty is a simple, safe and effective method for correction of prominent mandibular angle and malar, which accords with rules of aesthetic surgery.

局部浸润麻醉下下颌角肥大及颧骨突出磨削术是一种操作简便、安全合理的术式，并发症少、恢复快、符合美学标准及美容手术原则。

AIM:To observe the effect of mandibular contouring surgery with and without partial resection of the masseter muscle on the mandible motor function.

目的：观察下颌角整形术中去咬肌和不去咬肌两种术式对下颌运动功能的影响。

It can reach the submaxilla edge in part of old people; The bottom forms one curve following the eye lower eyelid; The medial terminal line is nasolabial; The lateral terminal line is from the junct of malar bone and malar arch to the angulus oris inferolateral or submaxilla edge.

皮下脂肪有一个近似三角形增厚的区域，三角形的尖位于口角外下方，约平下颌角平面，在部分老年人可达下颌缘；底部沿眶下缘呈一弧线；内侧界为鼻唇沟；外侧界从颧骨和颧弓交界到达口角外下方或下颌缘。

The fractures were fixed by the titanium mini-plate according to the Champy's ideal fixture line of the mandibular fracture, and the displacement of the fragments was attained by simulating occlusion on incisors, molars of the fracture side and non-fracture side.

分别在下颌骨正中联合、下颌体及下颌角设定单一的线形骨折线，模拟此三部位骨折。

The results of Pancherz analysis shows that the correction of negative overjet is mainly due to the advancement of maxilla and upper incisors. But the position changes of mandible and lower incisors imply that severe maxillary hypoplasia with high angle and/or mandibular retrusion is contraindicated by the method conducted in this study.

头影测量侧位片Pancherz分析法的分析结果表明，本研究中上颌后缩患者反覆盖的矫治主要由上颌骨、上切牙的前移引起的，但下颌骨和下切牙位置的变化提示适应症的选择应注意避免上颌后缩同时伴有高下颌角和／或下颌后缩的患者。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
