ABSTRACT

The three auditory ossicles in the middle ear; the malleus, incus and stapes forms an articulated chain across the tympanic cavity. Congenital malformations, Sclerosis, ankylosis or any disease of these ossicles causes immobilization and dissociation of the chain leading to hearing loss. Surgeons are performing surgeries for deafness like ossicular replacements and ossiculoplasty. This study is aimed at determining the morphometric dimensions of Incus in cadaveric specimen. The study was carried out on 70 incus (R= 34, L=36), which were collected from 57 adult male cadavers. The various measurements parameters were taken with the help of digital Vernier caliper and weighed with mettler Toledo weighing balance. Results revealed no statistical significant difference (p > 0.05) between morphometric measurements of the bone of right and left side. The knowledge of the morphometric data will help the otologic surgeon during reconstructive surgery and provide necessary information for the prosthesis design.
