With respect to the outer ear occlusion effect (mechanism 1) and middle ear ossicle inertia (mechanism 2), the pressure difference across the basilar membrane, inducing its displacement, is a result of the vibrations of the tympanic membrane (occlusion effect) or of the stapes footplate (ossicle inertia), which act inward to the inner ear, as in AC.
Illustration of scleral ossicles in an eastern screech owl shows how they help to prevent collapse of the globe, even if it has been ruptured.
Crampton's muscle originates in the sclera, below the scleral ossicles, and contracts to flatten the cornea along its periphery and bulges the center, increasing refractive power (BAYON et al., 2007; KERN & COLITZ, 2013; WILLIAMS, 2012).
HRCT also helps in diagnosing early erosive changes in the ossicles. The lenticular process of the incus is the first ossicle to be disrupted with loss of the "ice cream" cone appearance seen on the scan.
In patients with COMC, different degrees of destruction in the ossicles may be observed and after complete eradication of pathology, in many patients, ossicle reconstruction may be performed with autograft ossicles or allograft materials (16).
The technology is based on completely contact-free fiber-optic technology, which senses the tiniest ossicle movements and uses them to stimulate the acoustic nerves.

For each specimen, the volume of the middle ear ossicles was obtained by the volume of water displaced in a sealed microsyringe, and this value was subtracted from the volume of the corresponding cast to obtain RBV.
