简介:客观:为了学习寻找鼻音上的治疗学的效率和effecacy指导oflaser途径,为canalicular撕裂在吻合打破撕碎的眼泪的小管的结束。方法:受不了创伤的劣等的canalicular撕裂的49个病人(49只眼睛)被划分成控制组和指导激光的组。在眼泪的斑点和鼻音之间的距离撕碎的眼泪的小管的破结束是超过6公里。在眼皮损伤的管理的功课期间,病人被canalicular吻合操作在分别地在撕碎的眼泪的小管的结束找打破的鼻音与传统的方法和指导激光的方法对待。1条公里直径的硅酮试管作为stent在眼泪的经过被把管子插进4~6个月。结果:Inthe指导激光的组,在在撕碎的眼泪的小管的破结束找鼻音的吝啬的时间是(5。75±1.49)纪录,操作的吝啬的时间是(49.21±3.37)纪录;两个比控制组的显著地短(P<0.01)。指导thelaser组的痊愈率是96.55%,比控制组,但是没有统计意义(P>0.05)的高。结论:指导激光的方法对比传统的途径,和病人得更少的疼痛在撕碎的眼泪的小管的结束找打破的鼻音并且在canalicular吻合操作损坏快得多、更方便。

简介:与ipsilateral联系的Hoffa骨折大腿骨的柄骨折是很稀罕的。损害的这种稀罕类型的三个盒子回顾地被考察。大腿骨的柄破裂和Hoffa破裂的地点被记录。所有大腿骨的柄破裂与内部固定被管理。为Hoffa破裂的错误诊断的率被记录。影响的膝的功能在二年后续为特殊外科(HSS)分数根据修改医院被评估。大腿骨的破裂在所有三个盒子中横向或合成。IpsilateralHoffa破裂在一种情况中在二种情况,和侧面的髁中发生在中间的髁。一仅仅Hoffa破裂外科手术前地被识别。所有大腿骨的柄破裂太平无事地愈合了。在其Hoffa骨折正确地被诊断的病人,修改HSS分数是94。在另一个病人,其Hoffa断裂,被第二个手术对待,修改HSS分数是93。并且在第三个盒子中,为Hoffa破裂拒绝了另外的操作,修改HSS分数仅仅是70。决定性地大腿骨的柄骨折能与ipsilateralHoffa骨折被联系,特别在摩托车事故。这类损害是很稀罕的,错误诊断是普通的。
