Abstract
Aim: Most of the studies were on adult ossicles. In this present work, the aim is to study the morphometry of the ear ossicles in the human fetuses and use of the study in medical applications.
Materials and Methods: This study is performed on 100 sets of middle ear ossicles, each set consisting of Malleus, Incus and Stapes, which were taken from 50 fetal cadavers left and right sides of both.
Result: The morphometric data of malleus and incus in their length are 5.21mm and 4.85mm, the height of the stapes is 2.52mm. The indices of malleus, incus and stapes are 51.28, 67.54 and 88.12mm.
Conclusion: The study of morphometry in the ear ossicles of the human fetal cadavers can be useful for prosthetic surgical reconstruction.
