The crus breve incudis is an important marker for operation. The anatomical position of PE is constant. The depth of PTC affects the procedure for cochlear implant surgery via mastoid process-facial recess approach. The location of vestibular window and the round window is relatively stable, so the stapes head can be used as a reference for drilling scala tympani.

结论砧骨短脚是手术的重要标志；锥隆起解剖位置恒定；后鼓室的深浅对该进路的人工耳蜗植入手术的难易程度有重要影响；前庭窗与圆窗的位置关系相对稳定，因此镫骨头可作为参照标志来确定鼓阶钻孔的位置。

The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

扫描模式使用临床常用的颞骨螺旋扫描方式：管电压120 kV，准直宽度20×0.6 mm，视野200 mm，重建矩阵512×512，旋转时间1 s/r，重建层厚0.6 mm，重建间隔0.3 mm，分别改变管电流(380、300、200、160、120和80 mA)和螺距(0.8、1.0和1.2)进行扫描和重建，然后对颞骨进行横断面、冠状面和双斜面多平面重组，于重组后的横断层面图像上选取弓形下窝、鼓膜张肌腱、面神经隐窝、前庭导水管和锥隆起5个解剖结构，冠状面重组图像上选取盾板、横嵴、蜗窗、面神经的蛇眼征和锤骨外侧韧带5个解剖结构，双斜面重组图像上选取锤骨、砧骨、镫骨、上骨半规管和面神经管5个解剖结构，在双盲的情况下由放射学专家分别对各管电流和螺距下扫描的重组图像进行评分，随后进行统计学处理，从中筛选出满足诊断要求的最低管电流值和最大的螺距，分别采用患者25例(15耳)用该管电流值和螺距验证其可行性；然后利用模体分别测试各管电流和螺距下的图像的空间分辨率、噪声及其剂量长度积，并对测试所得参数数值进行比较和统计学处理。

中耳骨是由锤骨、砧骨和镫骨这三块独立的骨骼组成，这种结构与其他任何纲目的动物都有所不同：爬行动物与两栖动物都只有单个耳骨，而鱼类则没有。

Numerical analysis is conducted and employed to predict the effects of middle ear cavity, malleus handle defect, hypoplasia of the long process of incus, and stapedial crus defect on sound transmission.

利用模型进行了外耳，中耳和内耳的声固耦合分析，研究了中耳腔，锤骨柄缺如，砧骨长脚畸形和镫骨足弓畸形对传声机制的影响。

Results CTVE could clearly demonstrate the shape,size,and relation of the normal auditory ossicular chain.A visualization rate of malleus,incus,and incudomalleal articulation was 100%,and was 32% for the stapedial footplate.However,in only 21% could the anterior and posterior crura of stapes be distinguished.Cholesteatoma was found in 12 cases with chronic otitis media,in which CTVE demonstrated varying degrees of destruction of the auditory ossicle.In 1 case with congenital anomaly,ossicle dysplasia was seen.

结果 CTVE能清楚显示正常听骨链的形态、大小及相互关系，锤骨、砧骨及锤砧关节的显示率为100%(38/38)，镫骨底板的显示率为32%(12/38)，只有21%(8/38)可以分辨镫骨的前、后脚；18例中耳炎患者中12例胆脂瘤形成，CTVE上有不同程度的听小骨破坏。1例中耳畸形显示听骨链发育异常。

Results The representation of the structures of ill ears on CTVE and its comparison with coronal and axial CT film and operation: In 24 purulent otitis media, CTVE had a coincidence of 91.7% with operation of handle of malleus, 95.8% of head of malleus,95.8% of long limb of incus ,100% of short limb of incus, 87.5% of limbs of stapes.
