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.

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.

Results:① The distance between handle of malleus and stapes head was(2.38±0.19)cm(2.00~2.70cm), the point selecting for measuring was outer margin of handle of malleus and stpes head.②The cross section form of one_third of the handle of malleus at the end, was triangle, the anteroposterior diameter of handle of malleus was(0.79±0.12)mm, the exterior and interior diameter was(0.58±0.10)mm at the crook point,the angle of line of manubrium mallei laid(83.24±8.33)°(66~98°)posteroinferior to arch of zygoma.③The long axis of prosthesis formed(27.60±1.75)°(24.6~30.2°)angle with the perpendicular of stapes.④The dependablity between the malleus_stapes distance and transverse diameter of tympanum, the location of umbo in tympanic membrane, the diameter of manubrium mallei, angle of line of manubrium mallei and arch of zygoma were not statistically significant.

Methods Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window ( OOFNC-ABORW ), between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.
