复位

Diplopia and disturbance of ocular movement are related to the incarceration of the extraocular muscles and the displacement of orbital wall, and the management is simple relatively. However, the treatment of enophthalmos is difficult because the orbital reconstruction is made to be complicated by the complex morphous of orbital wall and the limited operative area. This study introduced the use of CAD/CAM technique in orbital reconstruction, and the result is more satisfactory than traditional methods.

眶壁重建是其矫治的首要条件，然而，眶壁形态复杂，并有视神经由眶尖通过，加之术野受限，使精确的解剖复位很难完成，本文应用CAD/CAM技术，术前成型钛网并行眶壁重建，通过CT分析和眼科检查，证实该技术在眶壁重建的精确性上均较传统方法有明显提高，其中，眶内壁的修复程度和眶底修复形态的对称性，以及眶容积缩小程度反映了其形态修复的精确性，而置入深度则体现了在缺损修复范围设计中的优越性。

The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

逆地眼振型水平半规管良性阵发位置性眩晕的3种耳石可能位置如下：水平半规管前臂的管耳石、管侧的顶帽沉石(canal side cupulo-lithias1s)与囊侧的顶帽沉石，本文报告3例以快速转头治疗逆地眼振型水平半规管良性阵发位置性眩晕成功的病例，显示快速转头法对囊侧的顶帽沉石具迅速有效的治疗效果，对於逆地眼振型水平半规管良性阵发位置性眩晕的治疗，作者建议先以快速转头作治疗性诊断，若病人马上复原，诊断为囊侧的顶帽沉石；若眼振转为向地型，则诊断为水平半规管前臂的管耳石或管侧的顶帽沉石，进一步再以向地型的耳石复位法治疗病人。

Methods On the basis of the three-dimensional computed tomography, 75 cases of complex acetabular fractures were diagnosed and classified according to Letournel classification. They were treated through the anterior, posterior, combined anterior-posterior and the improved iliofemoral approaches. All the fractures were fixed with screws and AO reconstruction plates.
