![]() ![]() Similar sound transmission can occur if the passage of blood through the sigmoid sinus (a large vein that travels very close to the ear) is turbulent, either because of a diverticulum (a bit that sticks out) or because the bony wall of the sinus is rough or too thin. Here, a higher pressure of the fluid inside the head leads to pressure on the thin sheets of bone between the brain and the ear, causing the bone to become thin and in some cases for tiny holes to appear.
