Abstract

The three middle ear ossicles form an articulated chain, connecting the lateral and medial walls of the tympanic cavity. They amplify and transmit the sound vibrations to the cochlear receptors in the inner ear. Any malformations of these ossicles cause hearing problems. To study the morphometric measurements and morphological features of all the three ear ossicles of both the sides.
Method: 50 formalin fixed human temporal bones were dissected to remove ear ossicles for the study by dissection method. At DMCH Darbhanga.
Conclusion: The knowledge of variations of the ossicles and its morphometric data will help the otologist during reconstructive surgery and provide necessary information for the prosthesis designer. Comparisons of morphometric values of newborn ossicles with that of adult values suggest that these ossicles complete their morphometric development in foetal life
