神经孔

Objective To observe the CT findings of hypoplasia of cochlear nerve foramen.

目的探讨蜗神经孔发育不良的多层螺旋CT表现。

Neurologic symptoms are not common in patients with osteochondromas of the spinal column because most do not protrude into the spinal canal or neural foramens.

由于大部脊柱骨软骨瘤不会突入椎管和神经孔，所以该类患者少见神经症状。

The particular adantage of the en bloc, as opposed to intralesional, resection of cartilaginous tumors is that this reduces the likelihood of local contamination, which in turn stands to decrease the risk of local recurrence Howeer, the cartilaginous cap is more difficult to excise completely if the tumor protrudes into the neural foramens or spinal canal, as it did in our patient.

切除带软骨成分的肿瘤时，整块切除相对囊内切除的突出优点是：减少了局部污染可能，继而减小了局部复发的风险。如果肿瘤突入椎管或神经孔时，彻底切除软骨帽则会更加困难，本病例就是这样。

In response to repetitive strain and inflammation, the synovial l-z joints can fill with fluid and distend, resulting in pain from stretching the joint capsule.71 Distension of the articular recesses can also compress the exiting nerve root in the neural foramen or spinal canal, especially when the foramen is already narrowed by joint hypertrophy and/or osteophytes.

反复的应力与炎症反应，可使滑膜l-z关节充满滑液并扩张，导致关节囊收到牵拉产生疼痛。关节囊隐窝的扩张可以压迫神经孔出的神经根出口或压迫椎管内脊髓，尤其当由于关节肥大和/或骨赘形成已经存在椎间孔狭窄时发生率更高。

Magnetic resonance images showed a 7 cm deep soft tissue tumor in the upper back with extension to left neural foramen of 4th thoracic spine.

磁振造影扫描发现在其上背部有一约7x5x3立方公分的软组织肿瘤，并沿著左侧第四神经孔侵犯到脊柱内。

Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.

对经曲面断层片筛选出的18例19枚埋伏牙进行牙科三维CT检查，扫描层厚1.0mm，重建后进行图像三维断面显示（包括水平位，矢状位，冠状位），对牙位图像进行分析及测量（包括埋伏牙牙长轴的角度，牙根弯曲度，牙冠的最大径，与骨皮质的距离，与邻牙根、神经孔／管的距离；骨质的厚度、高度等）。

METHODS: Two three-dimensional finite element pelvis models were established:① an intact pelvis model,② a defective pelvis model on which subtotal sacrectomy was performed cephalic to the S1 neural foramina.

分别构建完整骨盆和经S1神经孔上缘水平施行骶骨次全切除术后的缺损骨盆的三维有限元模型。

Reerse-angled curettes and a burr were used to create a foraminotomy at S2, which allowed the S1 and S2 nere roots to be mobilized.

用反角刮匙和电钻行骶2神经孔切开术，松解骶1、骶2神经根。

MR imaging revealed an infiltrative enhancing epidural tumor at the dorsum of T2 to T5 levels with foraminal extension.

磁振造影图象发现－脑膜上的肿瘤位于胸椎第二到第五节部位并有向神经孔蔓延现象。

Results: Scans of 3D-FIESTA sequence combined with post-procession could precisely show labyrinth, nerves and vessels in inner ear and internal auditory canal, as well as the relationship between nerves and vessels around. As to the ability to evaluate nerves in IAC, MPR and VE was superior to MIP; As to the ability to display semicircularesin and cochlea, MIP was the same as double oblique MPR; It was important for VE and oblique sagittal MPR to display the position of foramina nervosa of IAC.

结果：3D-FIESTA序列扫描结合MPR、MIP和VE重组对内耳迷路及内听道内神经及血管显示清晰，能够清晰显示两者之间的关系，MPR和VE重组对神经的显示优于MIP重组，MIP对半规管显示与双斜面MPR并无明显差别，VE和斜矢状面对于内听道内各神经孔的位置关系具有重要意义。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
