Introduction: Various anomalies of these ossicles can lead to the hearing problems. Various congenital malformations of these ossicles have also been reported to cause hearing problems. To perform the microsurgical maneuvers and manipulations, so as to correct these abnormalities, surgeons need to fully conversant about the details of these tiny bones. So, the study was designed to report about the various variations of the ossicles which would help them while performing the reconstructive surgeries. Materials and Methods: 100 sets of middle ear ossicles (50 right and 50 left), each set consisting of malleus, incus and stapes were collected from 100 cadavers available among the various medical colleges of North India. The bones were carefully examined under the simple microscope. Results: Stapes is found to be most variable ossicle followed by malleus than incus. Various shapes of cruras, head, neck and obturator foramen of stapes were noted. Malleus too had number of variations among the head and manubrium shapes. Shapes of manubrium mallie were seen to be curved anteriorly or straight. Least variations were seen among incus. The most frequent being a notch in the inferior border of the short process.
Conclusion: The data in the present study depicts stapes with a large variety of variations anf incus to be the most stable on.
Key words: Ossicle, Ossiculoplasty, Otology, Stapes, Variation
