Why does thickening of the skull and jaw bones cause hearing loss?

Thickening of the skull and jaw bones can cause hearing loss by affecting the normal transmission of sound vibrations through the ear structures. When these bones become denser or enlarged, they can interfere with the movement of the ossicles (small bones in the middle ear) and disrupt the conduction of sound to the inner ear. Additionally, changes in bone structure may lead to alterations in the surrounding tissues, further impairing auditory function. Consequently, the overall efficiency of hearing can be compromised.
