![]() ![]() Tumors at the temporal bones or base of the skull can be benign (noncancerous) or cancerous. If the abscess becomes large enough, it can make a hole in the eardrum and affect the cranial nerves that pass through the temporal bones. However, some infections can form abscesses in the tissues surrounding the temporal bones.Ībscesses in these tissues can grow and potentially cause a blood clot in the internal jugular vein. Temporal bone infections can sometimes be mild and unlikely to cause permanent damage. Sometimes, doctors can treat hearing loss with hearing aids, cochlear implants, or surgery to reconstruct the middle ear. In some situations, particularly those in which blood or swelling was responsible for this loss, the hearing may come back or improve over time. Trauma around the temporal bone can cause hearing loss. If doctors believe inflammation to be the cause, they may treat this type of paralysis using a 1–3 week course of corticosteroids.Īfter a trauma, the fluid that surrounds the brain, called cerebrospinal fluid, can leak from the ears or nose. If a person has delayed paralysis of the facial muscles, they may have fluid buildup that is pressing on a nerve. Temporal bone fractures can involve damage to certain nerves or lead to bleeding in the brain. They will manage the bone fracture once they are confident that the person is in a stable condition. People with temporal bone fractures may present to the emergency department with the following signs and symptoms:ĭoctors treating a temporal bone fracture must first make sure that the injury is not life threatening. Males are at least three times more likely than females to sustain a temporal bone fracture. About one-quarter of temporal bone fractures occur as a result of sports injuries, gunshot wounds, and cycling accidents, among other injuries. ![]() Temporal bone fractures can occur due to motor vehicle accidents, assaults, or falls. ![]() These two structures also pass through the temporal bones. The brain receives oxygen-rich blood from the carotid artery, while the jugular vein carries blood out of the brain. Various cranial nerves pass through the temporal bones, so skull fractures that affect these bones can have serious consequences. The temporal bones are the thickest bones of the skull, but a heavy impact to the head can fracture them. ![]() the squamous region, which is the largestīelow is a 3D model of the temporal bone, which is fully interactive.Įxplore the 3D model, using your mouse pad or touchscreen, to understand more about the temporal bone.Ī range of injuries and medical conditions can affect the temporal bone, including those below.The temporal bones comprise four regions: The brain then interprets these sounds.īalance involves several areas of the inner ear, including the vestibule and semicircular canal. The cochlea contains hearing cells, which transmit sound information to the brain through cranial nerves. As they vibrate, they send sound signals into the oval window, a structure in the ear that leads to the cochlea. Sound enters the ear canal and makes the tiny bones (ossicles) inside the ear vibrate. The temporal bone surrounds the ears and protects nerves and structures that play a role in controlling hearing and balance. This name reflects the fact that gray hairs, which mark the passage of time, often start appearing around the temporal area of the head. Temporal comes from the Latin word tempus, which means time. Together, these bones fuse to create the neurocranium, which is the main cavity that surrounds and protects the brain and the brain stem. the occipital bone at the back and base of the skull.the two parietal bones that make up the top of the skull.They help form the sides and base of the skull, where they protect the temporal lobe of the brain and surround the ear canal. The temporal bones are two major bones in the skull, or cranium. Share on Pinterest Sergey Filimonov/Stocksy ![]()
