Abstract：
To study the morphology and anthropometry of human ear ossicles from cadaveric temporal bone and to study the variations of the human ossicles from ossiculoplasty point of view. 38 sets of ear ossicles were collected, each containing malleus, incus and stapes, from temporal bone dissection done in Vasantrao Pawar medical college, Nashik. They were studied under microscope & anthropometrical, morphological evaluation done. Malleus showed variations in handle where 61% were straight and 39% curved. Weight of malleus ranged from 0.03-0.06 gm. The length ranged from 5.5 to 8.2 mm. Incus showed morphological variation in lenticular process which was present in 73% incii. Weight of incus ranged from 0.04 to 0.09 gm, average length of long process 3.5 mm, width of body 4 mm. In stapes variations was seen with head of stapes which was absent in 21% bones. With increasing awareness about postop hearing status, this study will add up in knowledge of morphological and anthropometric variations that exists in Indian population, help otologists to understand middle ear dynamics better which will improve results of ossiculoplasty.
摘要：
从尸体颞骨研究人耳小骨的形态和人体测量学，并从骨成形术的角度研究人耳小骨的变化。收集了38套耳小骨，每个都含有锤骨，砧木和骨,来自VasantraoPawar医学院的颞骨解剖，纳西克.他们在显微镜和人体测量学下进行了研究，进行形态学评估。锤骨显示出手柄的变化，其中61％是直的，39％是弯曲的。锤骨的重量范围为0.03-0.06gm。长度范围从5.5到8.2mm。针叶在透镜状过程中表现出形态变化，占73％。砧骨的重量范围为0.04至0.09gm，长过程的平均长度为3.5mm，身体的宽度4毫米。在the骨中，可以看到the骨的头部变化，而21％的骨骼中没有。随着人们对听力状况的认识日益提高，这项研究将增加印度人口中存在的形态和人体测量变化的知识，帮助耳科医生更好地了解中耳动力学，这将改善骨成形术的结果。
