Mastoid bone

As aforementioned, there are a number of air-filled cavities called mastoid cells inside the bony protrusion that directly communicates with the middle ear. In case of an ear infection, the mastoid cells may become septic if the infectious matter drains in to the posterior portion of the ear. This condition is clinically termed as “mastoiditis”. A swollen mastoid process typically produces symptoms like excruciating pain, tenderness/soreness, headaches, redness and hearing loss. Treatment with antibiotics as well as use of ear irrigation can aid in the removal of the contagious material. Severe blow to the head can often hurt the skull and cause serious injury to the pyramidal process as well as to the temporal bone. Fractures or bruises to the mastoidal structure can be clearly determined by using imaging techniques, such as radiography/X-ray. Depending on the severity of the case, doctors may suggest several methods to repair or stabilize the fractured bone.

If you suspect that you might have developed mastoiditis, we highly recommend that you seek the advice of a doctor as soon as possible. They will invite you for an initial ear examination, where they will look inside your ear to evaluate your ear's function and check for any inflammation. If they suspect you have an infection, they may recommend further tests to confirm the diagnosis, which may include x-rays, blood tests and swabbed ear-fluid cultures. If your infection is thought to be severe, you may also be sent for a CT or MRI scan.

The temporal bone is one of two bones that form parts of the sides and base of the cranium. A temporal bone on each side of the skull joins the parietal bone along the squamosal suture. The superior temporal line is the topmost curved line on the parietal bone and lies above the inferior temporal line. This is where the temporal fascia attaches. The inferior temporal line also lies on the parietal bone, and is the site of attachment of the temporal muscle. Located near the lower edge is a gap, the external auditory meatus, which leads inward to parts of the ear. The temporal bones house the internal structures of the ear and have depressions, the mandibular fossae, which join the processes of the mandible. Below each external auditory meatus, there are two projections: a rounded mastoid process and a long, pointed styloid process. The mastoid process provides an attachment for certain muscles of the neck, while the styloid process serves as an anchorage for muscles...
