Dimension dynamics of incus plays a important role to achieve the best postoperative results in reconstruction of the ossicular chain but still their length adjustment may pose a problem clinically. Hence the present study is an attempt to identify all possible measurements of incus both parametric and non parametric so as to provide a vivid description for prosthesis manufacture. Clavaria of 30 cadavers were removed and the incuses were extracted of both the sides and their dimensions were measured from digital vernier calliper and weights were measured by digital analytical balance. All the datas were analyzed by medcalc software. The present datas were compared with the previous studies and a positive correlation was deduced between its various dimensions and its weight and angle and distance between the two processes. This study will give a new horizon for prosthesis designer and teaching the medical students about the basic structure of the middle ear as well as its related significance in Clinical Medicine and ENT.
