Abstract :In this study, it was aimed to determine the morphometric characteristics of the bones forming the ossicula auditus of Morkaraman sheep and to reveal the differences between sexes and sides. For this purpose, 24 (12 females/12 males) craniums of Morkaraman sheep were used in the study. After the craniums were macerated, the ossicula auditus in the cavum tympani were dissected out and morphometric data were determined by taking linear measurements. Sexually dimorphic structures and homotypic variations of the obtained morphometric data were statistically calculated. It was observed that the bones forming the ossicula auditis were malleus, incus and stapes, respectively; when the morphometric data obtained were analyzed, it was determined that there were statistically dimorphic differences between sexes in the parameters of malleus lenght, width of the caput mallei and length of the manubrium mallei (P 0.05). In the correlation analysis of the morphometric parameters of the ossicles, weak, moderate and strong correlation was observed in the positive direction, while only weak correlation was observed in the negative direction. As a result, it is thought to contribute to taxonomic and experimental studies by determining the morphometric parameters of the ossicula auditis bones of Morkaraman sheep.
