Aeration of the mastoid bone with resulting thinning of the osseous walls is believed to be a predisposing factor for developing this abscess. Incomplete mastoid pneumatization in infancy and early childhood is responsible for the rare appearance of a Bezold abscess, with only five cases reported in children under 5 years of age (, 20) Once the bone covering the infection within the mastoid cells is removed, the resultant bony defect is called a mastoid cavity. Some surgeons leave the mastoid cavity open into the ear canal. This allows the surgeons to inspect the mastoid cavity easily. Others close up the mastoid cavity with bone, cartilage or muscle from around the ear The mastoid bone is located in your inner ear and may not be visible due to the infection.

  1. The mastoid portion forms the posterior border of the temporal bone and is highly pneumatized in most individuals, with a communicating honeycomb in its interior known as mastoid cells (Fig. 2). The mastoid process provides the attachment for the sternocleidomastoid (SCM) muscle, which gives the neck much of its mobility
  2. A few fibers of the SCM also insert on the bottom of the occipital bone, which is located right next to the mastoid process, and forms, again, the bottom of, the skull. The SCM muscle is of interest to anatomists because the unique position it occupies in the neck makes it key to understanding the layout of cervical muscles
  3. The occipital belly lies close to the occipital bone. The muscle originates at the mastoid part of temporal bone as well as the occipital bone's superior nuchal line and ends at the galea aponeurotica. It exchanges information with frontalis through an intermediate tendon. The muscle forms the posterior section of the occipitofrontalis muscle

The bone stimulator is firmly held against the bone of the skull at a location known as the mastoid process (although the mandible and zygomatic arch also work) and the stimuli are produced. The stimuli are conducted through the bone of the skull to the cochlea (which is embedded in the mastoid bone), by passing the outer and middle ears Description. A large irregular cavity is situated at the upper and front part of the temporal bone. It is called the mastoid antrum (tympanic antrum), and must be distinguished from the mastoid cells, though it communicates with them.Like the mastoid cells it is filled with air and lined by a prolongation of the mucous membrane of the tympanic cavity, with which it communicates Mastoid surgery, or mastoidectomy, involves drilling a hole in the mastoid bone and removing the infected air cells.

Mastoid air cell fluid is a commonly seen, but often dismissed finding. Given the location of the mastoid portion of the temporal bone and its location adjacent to vital structures, a careful evaluation is important for the emergency radiologist. While occasionally benign, fluid within the mastoid air cells can be an early sign of more severe pathology, and familiarity of regional anatomy. Muscular Attachments. The temporal bone serves as a point of attachment for many muscles. Due to the involvement of the temporal bone in forming the temporomandibular joint (i.e. joint of the jaw) some fibres from muscles of mastication such as the temporalis and masseter muscles attach to the temporal bone. In addition to this the mastoid process of the temporal bone is a major site of muscle. The mastoid is located just behind the ear.
