下颌舌骨的

ABSTRACT:OBJECTIVETo study the correlation between anatomic structure of the inferior alveolar nerve canal and dental implantation by measuring mandible innervation esemplarsMETHODSThe intramandibular course of mandibular canal and its dimendion were measured in 15 mandibles with teeth; the relationship between blood vessel and nerve was observed in 5 fresh samples in which the artery was filled; and then the data were analyzed by statisticsRESULTSThe mandibular canal was close to the lingual side and the inferior margin of the mandible, the mandibular canal and the 10mm underside of mandible were parallel in the region of the first and the second molars, it runned outboard to genal aperture when it was hereabout genal aperture, and the blood vessel lay above nerve in the mandibular canalCONCLUSIONIn implant operation performed according to normal anatomy, injury to inferior alveolar nerve may be avoided.

［目的］探讨下颌管的解剖结构与牙种植的关系［方法］选取15具牙列完整的成人离体下颌骨标本和5具经过动脉血管内灌注的新鲜标本，测量下颌骨在每个牙位截面上有关牙槽嵴及下颌管的相关数据，进行统计学分析［结果］牙槽嵴顶以及下方10mm宽度由前向后逐渐增宽；牙槽嵴由上向下逐渐增宽；下颌管位于下颌骨体内下方走行中偏舌侧，并近下颌骨下缘，在下颌第1，2磨牙区下颌管走行与下颌下缘成平行状，在近颏孔处转向外和向颊侧出颏孔；下颌管内血管位于下牙槽神经之上［结论］牙种植术中按正常解剖部位并且侧重颊侧骨板操作，可避免损伤下牙槽神经；如果术中下颌管内突然涌出大量新鲜血液，则提示若继续手术可能损伤下牙槽神经。

After submaxilla antedisplacement, direction and distance of hyoid bone is a view point of curing OSAHS patients.

下颌前移后，舌骨向前上移动的方向和距离是治疗OSAHS成功的一个观测点。

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%。

Feature of cephalometric hard tissue in patients with OSAHS: It was characterized that cranio-maxillo-facial hard tissue of submaxilla significantly retracted upward posteriorly and the distance from hyoid bone to mandibular plane increased obviously.

阻塞性睡眠呼吸暂停低通气综合征患者的头影硬组织测量特征为：以下颌改变为显著的颅颌面硬组织结构向后上缩进和舌骨至下颌平面距离明显地增加。

MethodsLFA was extended as far as possible toward the undercut area behind the mylohyoid ridge in 23 patients.

23例病人全口义齿修复时舌翼区尽量伸展至下颌舌骨嵴后的倒凹区内。

Methods 25 (50 sides) adult skulls were dissected to observe the c ourse, distribution and bilateral anastomosing branches of the mylohyoid nerve.

在25具(50例)尸头上解剖观察了下颌舌骨神经在颌下的走行、分支及双侧分支吻合情况。

The results from the cluster analysis and the principle component analysis based on the mean measure of divergence of eight groups of Mongoloids show that the Guangrao skeletons belong to the East Asian Mongoloid group and we also find that mylohyoid bridge, double h...

同时本文结果提示，在明确蒙古人种地区类型的主成分分析研究中，贡献率较大的三个小变异特征为下颌舌骨肌线桥、舌下神经管二分、眶上孔，这将为以后人们用小变异方法从事这方面的研究中如何选择观察项目方面提供了基础

The main changes were the downward and backward rotation of the mandible, the retrusion of the lower incisors, the protrusion of the upper incisors.FR-Ⅲ also promotes the growth of maxilla and reaches the normal relationship of the anterior overjet and overbite.

结果：FR-Ⅲ能矫正上下颌基骨异常的矢状关系，主要变化是下颌骨向下、向后旋转，改变下颌骨生长的方向，同时使下颌切牙舌倾、上前牙唇倾，上颌骨向前生长。

METHODS: As a pilot study, we prospectively evaluated 30 consecutive patients who underwent anterior cervical diskectomy and fusion to assess the interobserver accuracy of palpating the mandibular angle, hyoid, carotid tubercle, and thyroid and cricoid cartilages.

作为先导研究，我们前瞩性的评估连续30例行椎间盘切除并融合术的病人，评价触摸下颌角、舌骨、颈动脉结节、甲状软骨和环状软骨时目标观察物的准确度。
