Morphometric Dimensions of Male Auditory Ossicles among Nigerian Population.

Ear is an organ that exhibits complicated organization in all
organisms in terms of its anatomical and functional features. Overall, in addition to
receiving sounds and auditory perception, ear plays an important role in body homeostasis.

The middle ear communicates to the tympanic cavity by the tympanic membrane and
communicates with the nasopharynx by the auditory tube. The connection between
the middle ear and the pharynx is
closed except for swallowing or yawning.

The opening of this connection allows the air pressure between
the external ear and the middle ear to be balanced. The transmission of sound
waves across the tympanic cavity is mediated by three auditory ossicles
including malleus, incus and stapes in a latero-medial sequence.

Auditory ossicles transfer the sound vibrations in the tympanic
membrane from the middle ear to the inner ear.

These ossicles are located in the petrous part of the temporal
bone and in the dorsal aspect of the
tympanic membrane and form a chain
across the tympanic cavity from
tympanic membrane to fenestra vestibule.

These bones are bound together by articulations and have ligamentous
connections with the walls of the middle ear cavity. The aim of this study was
to provide the morphometric dimensions of
male auditory ossicles among the Nigerian population.
