Mastoiditis definition of mastoiditis by Medical dictionary https: It is almost always associated with otitis media , an infection of the middle ear. In the most serious cases, the bone itself becomes infected. The mastoid is a part of the side temporal bone of the skull. It can be felt as a bony bump just behind and slightly above the level of the earlobe. The mastoid has been described as resembling a "honeycomb" of tiny partitioned-off airspaces.
The mastoid is connected with the middle ear, so that when there is a collection of fluid in the middle ear, there is usually also a slight collection of fluid within the airspaces of the mastoid. Mastoiditis can range from a simple case of some fluid escaping into the mastoid air cells during a middle ear infection, to a more complex infection which penetrates through to the lining of the mastoid bone, to a very severe and destructive infection of the mastoid bone itself.
Mastoiditis is caused by the same types of bacteria which cause middle ear infections Streptococcus pneumoniae and Haemophilus influenzae , as well as by a variety of other bacteria Staphylococcus aureus, Pseuodomonas aeruginosa, Klebsiella , Escherichia coli , Proteus, Prevotella, Fusobacterium, Porphyromonas , and Bacteroides.
Mastoiditis may occur due to the progression of an untreated, or undertreated, middle ear infection. Symptoms of mastoiditis may at first be the same as symptoms of an early middle ear infection. With progression, however, the swollen mastoid may push the outer ear slightly forward and away from the head.
The area behind the ear will appear red and swollen, and will be very sore. There may be drainage of pus from the infected ear. In some cases, the skin over the mastoid may develop an opening through which pus drains. Mastoiditis is usually suspected when a severe middle ear infection is accompanied by redness, swelling, and pain in the mastoid area. A computed tomography scan CT scan will show inflammation and fluid within the airspaces of the mastoid, as well as the erosion of the little walls of bone that should separate the air spaces.
If there is any fluid draining from the ear or mastoid, this can be collected and processed in a laboratory to allow identification of the causative organism.
If there is no fluid available, a tiny needle can be used to obtain a sample of the fluid which has accumulated behind the eardrum. Identification of the causative organism guides the practitioner's choice of antibiotic. Depending on the severity of the infection, the antibiotic can be given initially through a needle in the vein intravenously or IV , and then as the patient improves by mouth.
In the case of a very severe infection of the mastoid bone itself, with a collection of pus abscess , an operation to remove the mastoid part of the temporal bone is often necessary mastoidectomy. Abscess — A pocket of infection, usually including a collection of pus. Meningitis — Inflammation and infection of the tissues covering the brain and spinal cord the meninges. Otitis or oteitis — An infection of the middle ear; marked by an enlargement of bone, tenderness and dull aching pain.
With early identification of mastoiditis, the prognosis is very good. When symptoms are not caught early enough, however, a number of complications can occur. These include an infection of the tissues covering the brain and spinal cord meningitis , a pocket of infection within the brain abscess , or an abscess within the muscles of the neck. All of these complications have potentially more serious prognoses. Prevention of mastoiditis involves careful and complete treatment of any middle ear infections.
It most often follows sore throat and respiratory infection but can also be caused by diseases such as diphtheria, measles, and scarlet fever. Symptoms include earache and a ringing in the ears. The mastoid process may become painful and swollen. Treatment formerly was limited to mastoidectomy , in which infected cells were removed surgically. Today, however, use of antibiotics has made it possible to check most cases at an early stage, so that surgery can be avoided. Inflammation of the mastoid process and mastoid cells.
It is characterized by earache, fever, headache, and malaise. Swelling of the mastoid process often displaces the pinna anteriorly and inferiorly. The infection is difficult to treat, often requiring antibiotic administered intravenously for several days.
