Sclerosis of the left mastoid air cells refers to abnormal hardening or thickening of the bone in the mastoid region of the skull. This can be caused by chronic infection, inflammation, or other conditions affecting the mastoid air cells. It may result in symptoms like ear pain, discharge, and hearing loss.

What is the term there is haziness of the left middle ear cavity and mastoid antrum with sclerosed mastoid air cells due to chronic oto-mastoiditis?
The term for haziness of the left middle ear cavity and mastoid antrum with sclerosed mastoid air cells due to chronic oto-mastoiditis is called "chronic suppurative otitis media with mastoiditis." This condition is characterized by long-standing inflammation and infection of the middle ear and mastoid bone. Treatment typically involves antibiotics and sometimes surgery to remove the infected tissue.
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.
Where in the ear region are the air cells located?
The air cells in the ear region are located in the mastoid bone, which is a bony prominence behind the ear. These air cells are part of the mastoid process and are connected to the middle ear cavity. They play a role in regulating air pressure and drainage in the middle ear.
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 is the temporal part of the bone that can be seen and felt as a prominent lump just posterior to the ear?
This part is called as mastoid process. Besides it lies a styloid process. There are air cells inside the mastoid process.
What cells are removed during a mastoidectomy?
During a mastoidectomy, the mastoid air cells located in the mastoid bone are removed. These air cells are typically removed to treat chronic ear infections or other diseases that affect the mastoid bone which houses these cells.
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.

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.
Mucous membranes within the air cells of the mastoid process are most likely to become infected by bacteria spreading from the?
middle ear. The mastoid air cells are directly connected to the middle ear, so any infection within the middle ear can easily spread to the mastoid process through these air cell connections.
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 does the mastoid process do for an ear?
The mastoid process serves as an attachment site for neck muscles. It also houses air cells that help regulate air pressure in the middle ear and protect the inner ear structures. Additionally, it provides stability and support to the skull.
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 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.
