雌激素可能通过增强颏舌肌肌功能的途径对上气道稳定性发挥保护作用。

ABSTRACT:OBJECTIVETo study the correlation between anatomic structure of the inferior alveolar nerve canal and dental implantation by measuring mandible innervation esemplarsMETHODS The 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。

BACKGROUND: We evaluated the usefulness of the hyomental distance ratio, defined as the ratio of the HMD at the extremeof head extension to that in the neutral position, in predictingdifficult visualization of the larynx in apparently normalpatients, by examining the following preoperative airway predictors,alone and in combination: the modified Mallampati test, HMDin the neutral position, HMD and thyromental distance at theextreme of head extension and HMDR.

背景：我们通过以下单一或混合的术前气道指标评估了颏舌距离比在预测表面上正常的患者喉镜检查时发生困难视野的可靠性：改良Mallampati 试验、头部中立位时的HMD、头部最大伸展位时HMD和甲颏距离以及HMDR.HMDR定义在为头部最大伸展位和中立位时HMD的比值。

For class III malocclusion there are no significant differences in Ls-SGo,Li-SGo,upper lip length , lower lip length , Cm-Sn-Ls, upper lip angle of inclination and Li-H line . There are significant differences in lower lip angle of inclination , mentolabial sulcus angle , upper lower lip angle , H angle.

安氏Ⅰ类错合患者与安氏Ⅲ类错合患者相比，在上唇突点到SGo距离、下唇突点到SGo距离、上唇长、下唇长、鼻唇角、上唇倾角和下唇突点到H线距这些测量指标上无显著性差异；其他表示唇部形态和位置的指标，下唇倾角、颏唇沟角、H角、上下唇角都有显著性差异。

Methods 160 reverse flow axial flaps were used to repair the defects of eyelid, nose,chin,lip,neck,vagina,and penis,including retroauricular flap based on superficial temporal artery,auricular composite flap based on supraorbital vessels,neck-submandibular flaps based on contralateral side mental artery,nape-scapulo-dorsal flap based on transverse cervical artery,and medial ...

方法随机选择160例近22年来应用较广的5种动脉跨区供血反流轴型皮瓣，即：颞浅血管为蒂的乳突区皮瓣、眶上血管为蒂的岛状耳廓复合组织瓣、颏下动脉蒂的对侧颏颈皮瓣、颈横动脉供血的项肩背皮瓣、会阴动脉供血的股内侧皮瓣，考查其完全成活率、部分成活率、完全坏死率、动脉缺血发生率、动脉缺血致皮瓣坏死率、静脉淤血发生率、静脉淤血致皮瓣坏死率等指标，并与我院同期内应用的常规顺流轴型皮瓣随机样本120例进行比较。

Despite a high success rate, intubation with theGlideScope is likely to be more challenging in patients withhigh Cormack and Lehane grade during direct laryngoscopy, highupper lip bite test score, or short sternothyroid distance.

尽管成功率高，在直接喉镜 Cormack 和 Lehane 等级高、上唇咬诊评分高或甲颏距离短的病人中使用 GlideScope 插管可能更具挑战性。
