①The distance between handle of malleus and stapes, the dia_meter of manubrium mallei are important to the design of prosthesis.

①锤骨柄与镫骨头之间的最短距离及锤骨柄的直径对赝复物的设计具有指导意义。

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.

结果：①锤_镫距离最短为(2.38±0.19)cm(2.00～2.70cm)，测量点为锤骨柄末端1/3处外缘和镫骨头；②锤骨柄末段1/3横断面形状接近三角形，弯曲处前、后方向直径为(0.79±0.12)mm，内、外方向直径为(0.58±0.10)mm；锤骨柄与颞线的成角为(83.24±8.33)°(66～98°)；③赝复物长轴与镫骨垂直方向成角平均为(27.60±1.75)°(24.6～30.2°)；④锤_镫距离与鼓室横径、鼓脐在鼓膜上的位置、锤骨柄直径、锤骨柄的方位的可能相关因素之间相关性检验无统计学意义。
