Methods Fifty adults ( 100 sides) skulls were measured by slide gaud, and observed course, situation and structure character of carotid canal in petrosal apex of temporal bone in63 sides. 方法采用游标卡尺和厚度测量仪,观测100侧成人颅骨标本,观察63侧颞骨颈动脉管在岩尖部走行、位置及骨质结构特点。
Methods The angioplasties were performed while balloons were positioned in the carotid canal of the temporal bone by trans-radial approach in38 cases with atheromatous carotid stenoses. 方法经桡动脉入路在颈内动脉岩部放置阻塞球囊,对38例颈动脉粥样硬化性狭窄患者行支架置入术。
Methods 31 patients with total blindness were treated by transfrontal craniotomy decompression of optic nerve, which allowed complete decompression of the optic canal, incision of optic sheath, and removal of apical orbital bone fragments. 方法应用额部开颅视神经减压开放术治疗术治疗术前完全失明(无光感)患者31例,全程开放视神经管及视神经鞘膜,并取出眶尖的碎骨片。
Results The changes of bone trabecula, inferior margin and canal of mandible were present in osteoporosis, but the height of alveolar bone remained the same as the contral. 结果骨质疏松症与牙槽骨骨小梁、下颌管管壁和下颌骨下缘骨皮质吸收之间明显相关,与牙槽骨高度无相关性。
Results: Mandibular canal was formed by a thin layer of compact bone in spongy bone of mandibular bone. 结果:下颌管是下颌骨的骨松质内形成较薄的骨密质骨管。
Results: The location and types of spinal fracture, spinal three columns structure, narrowing of spinal canal, the areas of cross section of spinal canal, the nerve roots and spinal cord to be compressed by bone segments were exactly revealed on CT. 结果:CT检查能准确揭示其骨折部位,骨折类型,脊柱三柱结构,特别是椎管狭窄及椎管横截面积与骨片对神经根和脊髓的压迫影像。
A survey of middle clinoid process and caroticoclinoid foramen ( canal) of the sphenoid bone 蝶骨中床突和颈床孔(管)的调查
Conclusion Anterior enlargement of the cervical spine canal can significantly increased volume as well as depress anterior part of the spinal cannel. Bone can be obtained union and increased the stability without damage the three columns structure. 结论经前路颈椎体纵向劈开扩大术,可以增加椎管容积、不影响脊柱三柱稳定结构。三、多姿多彩的艺术手法并改变了柱的破坏类型。
Conclusion: The bone regeneration resulting in stenosis of spinal canal after laminectomy consists of both bone regeneration from the defect margins and the chondral islands ossification in the fibrous tissue. 结论:椎板再生包括纤维组织软骨内成骨和椎板切缘的骨再生,再生造成椎管狭窄。
The therapeutic effect of nerve decompression and vertebral canal plasty combined with the screw-rod system fixation of posterior pedicle of vertebral arch and the fusion of bone graft is fine. 神经减压和椎管成型辅以后路椎弓根钉捧系统同定及植骨融合术治疗退行性下腰椎不稳疗效优良。
CT Analysis of External Auditory Canal Deformity due to Dysplasia of Tympanic Part of Temporal Bone 颞骨鼓部发育不良所致外耳道畸形的CT分析
The author discussed the importance of a full curettage, the advantage of decompression of the vertebral canal from anterior-external approach and inferior and the merits of fixing columna vertebralis with a large bone graft. 作者详细介绍了手术操作和椎间大块植骨的改进方法,重点讨论了彻底清除病灶的重要性,保留后关节突的椎管前外侧减压和大块植骨固定脊柱的优点。
Objective To analyze HRCT findings of external auditory canal deformity, and to discuss the relationship between the external auditory canal deformity and the dysplasia of tympanic part of temporal bone. 目的分析84耳外耳道畸形的高分辨率CT(HRCT)表现,探讨颞骨鼓部发育畸形与外耳道畸形的关系。
Results I. The REOR ( real ear occluded response) recorded in the ear canal by probe microphone was linearly increased with the intensity of bone conduction with 1 ∶ 1 slope. 结果1.探管麦克风在外耳道中记录的堵耳响应REOR随骨导强度增强呈1∶1线性增长;
In the images of the CPR reconstruction, the mandibular canal was composed of a thin compact bone, and extended to the midline and became thinner, and continued to be the mental foramen. 在CPR重建图像上,下颌管壁由一薄层骨密质构成,向中线延伸并逐渐变薄,在颏孔附近形成无管壁的腔道。
With the auditory canal as a symbol, Bone is divided into the part of around the internal auditory canal and the petrous apex. to grinding petrous bone in two parts. 以内听道为标志,可以将岩骨分为内听道周围部分和内侧岩尖部分共两部分来磨除岩骨。
Because the facial nerve trunk travels in the narrow facial nerve canal, it is difficult to understand directly the pathological and physiological changes of the facial nerve after temporal bone trauma or iatrogenic injury in clinical. 但面神经主干走行于狭窄的骨管中,临床上很难直接了解颞骨外伤或医源性损伤后面神经发生的病理及生理改变。
