MORPHOLOGICAL AND MORPHOMETRIC ANALYSIS OF EAR OSSICLES IN ADULT HUMAN CADAVERS IN RAJASTHAN POPULATION

Abstract

Introduction: Hearing function is a special sense present among higher animals and is one of the most important sensory inputs for sustenance of life. Aim: To study morphological and morphometric variation of ear ossicles in cadavers available at RUHS College
of medical sciences, Jaipur. Method: Study conducted on 32 human cadaveric temporal bones at Department of Anatomy RUHS
College of medical sciences, Jaipur. Formalin preserved human cadaveric temporal bones from the department of Anatomy, RUHS
– CMS Jaipur. Cadaveric heads of both sexes and adult more than 18 years of age with intact temporal region having intact ossicular
chain with no discontinuity or erosion were taken into study. Result: mean total length of Malleus in group LEFT and group RIGHT
were 8.07±0.40 and 7.71±0.35, respectively (p=0.011). The mean Weight of Stapes the left and right sides were 2.91±0.10and 3.29±0.34 respectively, (p=.023), groups were comparable according to Width of footplate. The three ossicles are morphometrically similar in both the ears except Incus, which showed the significant difference in left and right side. Conclusion: Measurements of morphometry in the ear ossicles of the human cadavers can be useful for prosthetic surgical reconstruction, would be very helpful in
designing the prosthesis in ossicular chain pathology
