Abstract

Introduction: The ear ossicles contained in tympanic cavity are responsible for the conduction of sound waves from external to inner ear. A very few studies have been reported regarding the morphometric details of these ear ossicles in females. The mean values of the various parameters of the three bones, malleus, incus and stapes, have been reported in the present study in female population of North India.

Materials and methods: 100 sets of middle ear ossicles (50 right and 50 left), consisting of malleus, incus and stapes were collected from 50 female cadavers available from the various medical colleges of North India.

Results: Our study provides the mean values of the various dimensions of the three bones in femae population of North India. There is no statistical differences between any of the morphometric measurements of the bones of right and left sides in females. However, a statistically significant difference is noted in the measurements of stapes between male and female population.

Conclusion: The results of the present study are not only of academic interest but would be very helpful in designing the prosthesis in ossicular chain pathology.
