What is Pneumatization of mastoid cells?

Concomitantly with growth, air cells develop in the normal mastoid by a process termed “pneumatization.” This process is governed by vital and anatomic factors, the influence of which causes each mastoid to attain an individual cell pattern which differs from that of its mate and is sufficiently characteristic for …

What is non Pneumatized?

The conchal type of sphenoid is known as non-pneumatized or rudimentary, the sinus does not reach into the body of the sphenoid bone.

What is sinus Pneumatization?

Sinus pneumatization is a continuous physiological process that causes the paranasal sinuses to increase in volume [5]. Sinuses give resonance to voice, contribute to the shape of the face, and provide some degree of warmth and humidification to inspired air [6].

What does Pneumatization mean for kids?

: having air-filled cavities.

What are the mastoid air cells?

The mastoid air cells are thought to protect the delicate structures of the ear, regulate ear pressure and possibly protect the temporal bone during trauma. When the mastoid cells become infected or inflamed, often as a result of an unresolved middle ear infection (otitis media), mastoiditis can develop.

Where are the mastoid air cells in relation to the Epitympanic recess?

The mastoid air cells are located posterior to epitympanic recess. They are a collection of air-filled spaces in the mastoid process of the temporal bone. The air cells are contained within a cavity called the mastoid antrum.

What are ethmoid air cells?

Definition. The numerous tiny-walled, fluid-filled cells that lie in the ethmoid bone of the skull (i.e. specifically lying in between the orbits and the upper parts of the nasal cavities), and collectively form the ethmoid sinus. Supplement.

What is pneumatization of the middle turbinates?

Extensive pneumatization of the middle turbinate, also called concha bullosa or bullous middle turbinate (BMT), is known to be one of the possible etiologic factors in nasal obstruction, recurrent sinusitis, and headache. In the first type, air cells were noted to pneumatize the vertical lamella of the turbinate.

What causes pneumatization?

of some factors that may influence maxillary sinuses pneumatization, such as heredity, nasal mucous membrane pneumatization, craniofacial configuration, bone density, sinus surgeries, growth hormones, air pressure within the cavity of the sinus and an age- related process.

What does the word pneumatization mean?

Medical Definition of pneumatization : the presence or development of air-filled cavities in a bone pneumatization of the temporal bone.

Where are the mastoid air cells?

The mastoid bone, which is full of these air cells, is part of the temporal bone of the skull. The mastoid air cells are thought to protect the delicate structures of the ear, regulate ear pressure and possibly protect the temporal bone during trauma.

What are mastoid air cells?

Mastoid cells, sometimes called mastoid air cells, refer to the air pockets formed by the honeycomb-shaped bone structure of the mastoid process. A projection of a portion of the temporal bone in the skull, the mastoid process is located behind the ear. These cells may be of different sizes, depending on where they are positioned within the mastoid.

What are the symptoms of mastoid air cell disease?

The disease is mild at first presentation, but leads to a serious life-threatening condition when not treated. SymptomsCommon symptoms of a moderate level of mastoid air cell disease include pain behind the ear, swelling of the lobe or a recent infection in the ear.

What causes fluid in mastoid cells?

Fluid filled or opacified mastoid air cells could be the result of past ear infection or sinusitis . Trauma to the skull like fractures or even craniotomy can also cause opacified mastoid air cells due to effusion of fluid from the mastoid cells.

What is fluid in mastoid air cells?

The mastoid bone, which is full of these air cells, is part of the temporal bone of the skull. The mastoid air cells are thought to protect the delicate structures of the ear, regulate ear pressure and possibly protect the temporal bone during trauma.
