What does it mean if you have fluid in the mastoid air cells?
Fluid in the mastoid air cells can indicate an infection or inflammation in the middle ear or mastoid bone. This condition is known as mastoiditis and may require medical treatment such as antibiotics or drainage. It is important to seek medical attention if you suspect you have fluid in your mastoid air cells.
Which bone houses the mastoid sinus?
The mastoid sinus is housed within the temporal bone, specifically within the mastoid process. It is a structure located in the inner ear that helps drain fluid and maintain proper ear function.
What does opacification of mastoid air cells mean?
Opacification of mastoid air cells refers to an abnormal density or fluid accumulation within the mastoid air cells of the temporal bone. This can be a sign of inflammation, infection, or other pathology within the mastoid region, often seen on imaging studies like CT scans. It may require further evaluation by a healthcare provider to determine the underlying cause and appropriate treatment.
What is the Treatment for fluid in the mastoid bone?
Treatment for fluid in the mastoid bone typically involves antibiotics to treat any infection present, as well as a procedure called mastoidectomy to drain the fluid. Surgery may be necessary to remove infected tissue and repair any damage. It's important to consult with an ENT specialist for proper evaluation and treatment.
What are the functions of the mastoid air cells?
The mastoid air cells of the temporal bones are an interconnected network of small sinus cavities which communicate with the middle ear via the aditus ad antrum superiorly. The middle ear, which does not communicate with the external auditory canal due to presence of a (normally) intact tympanic membrane (the "ear drum"), depends on the additional compliance of the air-filled mastoid air cells in order to allow the tympanic membrane to move in response to sound waves (= changes in air pressure). The tympanic membrane needs to be able to move freely in order to convert external pressure changes into movement of the ossicular chain of the middle ear, which in turn conveys that motion to the membrane-covered oval window of the fluid-filled cochlea. The cochlea is responsible for converting that movement into nerve signals to send to the brain for interpretation. Interestingly, the cochlea has a second small membrane-covered opening, the round window, to enable the fluid to move in the cochlea secondary to action of the ossicles on the oval window, similar to the function of the mastoid air cells in allowing the tympanic membrane to move in response to changes in external air pressure. If the mastoid air cells are absent or fluid filled, there is less compliance in the system, decreasing the ability for the tympanic membrane to move and transmit sound, decreasing auditory acuity. In addition, the mastoid air cells provide secretions that slowly travel from the mastoid air cells through the middle ear and into the posterior nasopharynx by way of the eustachian tubes in order to keep the middle ear clear of debris. The eustachian tubes are the structures that allow you to "pop" your ears in response to pressure changes, by equalizing pressures in the middle ear with the external environment through transmission of air from your nose and mouth. This is also the primary reason that people (and especially children, with their smaller eustachian tubes) almost always have fluid in their middle ears when they are suffering from upper respiratory tract infections ... the upper respiratory tract is contiguous with the middle ear by way of the eustachian tubes. N.B: The mastoid air cells are not "air bags" or "crumple zones" to protect the brain from injury; severe temporal bone injury carries significant morbidity (hearing loss, facial nerve paralysis, chronic infections, vascular injury of the carotid and internal jugular veins) and mortality, and the mastoid air cells themselves are highly protected with thick overlying cortical bone.
Where are mastoid sinuses located?
The mastoid sinuses are small air cells located in the mastoid process, which is a bony protrusion located behind the ear. The mastoid sinuses are connected to the middle ear and help regulate air pressure, as well as provide drainage for fluid.
What is bilateral mastoid fluid?
Bilateral mastoid fluid refers to the presence of fluid in both mastoid bones, which are located behind the ears. This can be a sign of infection or inflammation in the mastoid air cells, often seen in conditions such as mastoiditis or otitis media. Treatment usually involves antibiotics to clear the infection and possibly drainage of the fluid.
What does it mean if you have fluid in the mastoid air cells?
Fluid in the mastoid air cells can indicate an infection or inflammation in the middle ear or mastoid bone. This condition is known as mastoiditis and may require medical treatment such as antibiotics or drainage. It is important to seek medical attention if you suspect you have fluid in your mastoid air cells.
What is a simple case of mastoiditis?
In a simple case of mastoiditis some fluid escapes into the mastoid air cells during a middle ear infection.
What if there is fluid in the mastoid who should you see?
An ENT surgeon.

When lung tissue retains a excessive amount of fluid?
Pulmonary edema
When treated for an inflammation of mastoid cells is called?
The treatment for inflammation of mastoid cells is typically referred to as mastoiditis treatment. This may involve antibiotics to clear up any bacterial infection, pain management, and in some cases, surgical procedures to drain any fluid or pus buildup in the mastoid cells. It is important to seek medical attention promptly to prevent complications.
