Mastoiditis is an infection of the mastoid bone of the skull. Causes, incidence, and risk factors Mastoiditis is usually a consequence of a middle ear infection (acute otitis media). The infection may spread from the ear to the mastoid bone of the skull. The mastoid bone fills with infected materials and its honeycomb-like structure may deteriorate. Mastoiditis most commonly affects children. Before antibiotics, mastoiditis was one of the leading causes of death in children. Now it is a relatively uncommon and much less dangerous disorder. Symptoms * ear pain or discomfort o earache o pain behind the ear * redness of the ear or behind the ear * fever, may be high or spike (have sudden high increases) * headache * drainage from the ear Signs and tests An examination of the head may indicate mastoiditis. A skull X-ray or head CT scan or CT of the ear may show an abnormality in the mastoid bone. A culture of drainage from the ear may show bacteria. Treatment Mastoiditis may be difficult to treat because it is difficult for medications to reach deep enough into the mastoid bone. It may require repeated or long-term treatment. Antibiotics by injection, then antibiotics by mouth are given to treat the infection. Surgery to remove part of the bone and drain the mastoid (mastoidectomy) may be needed if antibiotic therapy is not successful. Surgical drainage of the middle ear through the eardrum (myringotomy) may be needed to treat the underlying middle ear infection. Expectations (prognosis) Mastoiditis is curable with treatment but may be hard to treat and may recur. Complications * recurrence * partial or complete hearing loss of the affected ear * destruction of the mastoid bone * facial paralysis * meningitis * spread of infection to the brain or throughout the body * epidural abscess Calling your health care provider Call your health care provider if symptoms indicate mastoiditis. Call for an appointment with your health care provider if a known ear infection does not respond to treatment or is followed by new symptoms, or if symptoms do not respond to treatment. Prevention Prompt and complete treatment of ear infections reduces the risk of developing mastoiditis.

∙ 15y agoThe mastoid bone is actually a portion of the temporal bone - the bone on the sides of the skull. The temporal bone is made up of several portions - the squamous, petrous, mastoid, and styloid portions.
The mastoid houses many air cells, rather than being solid bone, and many think this is to decrease the weight of the skull.

What is the job description for an ent specialist?
Ear, nose and throat specialists, also known as otolaryngologists or ENT specialists, are medical doctors responsible for surgical and medical treatment of the ears, nose and throat, as well as the related head and neck areas. Specialized skills of otolaryngologists include managing disorders of the upper pharynx and oral cavity, larynx (voice box), ears, nose and nasal passage, and face and neck. Almost all ENT specialists regularly handle cases like nosebleeds, adenoidectomies, infected mastoids, tonsillectomies and sinusitis.
Where are all the human weak points?
Some weak links are on the lef and right front sides on your throat. but not too hard because it will kill someone. There are also the temples, no not the big old pointy things used to worship, they are located above the outside points of your eyes. Again, not too hard. There are the mastoids which are right behing the earlobes. On the forearm, there two. These weak points are right under the wrist and about six inches below that. These are very sensitive. Then there is the elbow. The inside of the elbow has an exposed nerve. So does the outside of the elbow, but it is much harder to get to. The inside edges of the shoulder are also weak on certain peope. The collarbone is very sensitive, just disable do not hurt. Around the knee caps are also sensitive. so is almost the entires area of the ankle. The top center of the foot is also a very VERY sensitive part if you can get to just the right spot. It explains how women can hurt men by stamping down as hard as they can on a man's foot. There is also the diaphram. This would have your opponent gasping for air, but it is easy to recover from this so make a run for it after of make your next move. And that was the last one I'm going to give you.
Ear infection - chronic?
DefinitionChronic ear infection is inflammation or infection of the middle ear that persists or keeps coming back, and causes long-term or permanent damage to the ear.See also: Acute ear infectionAlternative NamesMiddle ear infection - chronic; Otitis media - chronic; Chronic otitis media; Chronic ear infectionCauses, incidence, and risk factorsFor each ear, a eustachian tube runs from the middle ear to the back of the throat. This tube drains fluid that is normally made in the middle ear. If the eustachian tube becomes blocked, fluid can build up. When this happens, germs such as bacteria and viruses can multiply and cause an infection. This is called an acute ear infection (acute otitis media).A chronic ear infection occurs when fluid or an infection behind the eardrum does not go away. A chronic ear infection may be caused by an acute ear infection that does not clear completely, or repeated ear infections. Fluid in the middle ear may become very thick. Sometimes, the eardrum (tympanic membrane) may stick to the bones in the middle ear.A chronic ear infection may cause permanent changes to the ear and nearby bones, including:Infection in the mastoid bone behind the ear (mastoiditis)Ongoing drainage from a hole in the eardrum that does not heal, or after the ear tubes (tympanostomy tubes) are insertedCyst of the middle ear (cholesteatoma)Hardening of the tissue in the middle ear (tympanosclerosis)Damage to, or wearing away of the bones of the middle ear, which help with hearing"Suppurative chronic otitis" is a phrase doctors use to describe an eardrum that keeps rupturing, draining, or swelling in the middle ear or mastoid area and does not go away.Ear infections are more common in children because their Eustachian tubes are shorter, narrower, and more horizontal than in adults. Chronic ear infections are much less common than acute ear infections.SymptomsA chronic, long-term infection in the ear may have less severe symptoms than an acute infection. It may go unnoticed and untreated for a long time.Symptoms include:Ear pain or discomfort, earacheUsually mildMay feel like pressure in the earFeverFussinessPus-like drainage from the earHearing lossNote: Symptoms may be continuous or come and go, and may occur in one or both ears.Signs and testsAn examination of the ear may show:DullnessRednessAir bubblesFluid behind the eardrumDraining fluid from the eardrumA hole (perforation) in the eardrumThe eardrum bulges out or pulls back inwardTests may include:Cultures of the fluid may show bacteria, and these bacteria may be resistant or harder to treat than the bacteria commonly involved in an acute ear infection.Skull x-rays or a CT scan of the head or mastoids may show that the infection has spread beyond the middle ear.Hearing tests may be needed.TreatmentThe health care provider may prescribe antibiotics if the infection may be due to bacteria. You may need to take antibiotics for a long time, either by mouth or sometimes into a vein (intravenously).If there is a hole in the eardrum, antibiotic ear drops are used. For a difficult-to-treat infected ear that has a hole (perforation), a dilute acidic solution (such as distilled vinegar and water) may be recommended by your health care provider.A surgeon may need to clean out (debride) tissue that has gathered inside the ear.Other surgeries that may be needed include:Surgery to clean the infection out of the mastoid bone (mastoidectomy)Surgery to repair or replace the small bones in the middle earRepair of the eardrumExpectations (prognosis)Chronic ear infections usually respond to treatment. However, your child may need to keep taking medicines for several months.Chronic ear infections are not life threatening, but they can be uncomfortable and may result in hearing loss and other serious complications.ComplicationsPartial or complete hearing loss due to damage of the middle earSlow development of language or speechParalysis of the faceInflammation around the brain (epidural abscess) or in the brainDamage to the part of the ear that helps with balancePermanent hearing loss is rare, but the risk increases with the number and length of infections.Calling your health care providerCall for an appointment with your health care provider if:You or your child has signs of a chronic ear infectionAn ear infection does not respond to treatmentNew symptoms develop during or after treatmentPreventionGetting prompt treatment for an acute ear infection may reduce the risk of developing a chronic ear infection. Have a follow-up examination with the health care provider after an ear infection has been treated to make sure that it is completely cured.ReferencesChole RA, Sudhoff HH.
