The mastoid cells (also called air cells of Lenoir or mastoid cells of Lenoir) are air-filled cavities within the mastoid process of the temporal bone of the cranium. The mastoid cells are a form of skeletal pneumaticity. Infection in these cells is called mastoiditis. The term cells here refers to enclosed spaces, not cells as living ...
Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside [1] the mastoid process. The mastoid process is the portion of the temporal bone of the skull that is behind
Otitis media with effusion (OME), also known as serous otitis media (SOM) or secretory otitis media (SOM), and colloquially referred to as 'glue ear', [27] is fluid accumulation that can occur in the middle ear and mastoid air cells due to negative pressure produced by dysfunction of the Eustachian tube.
A section of the mastoid process shows it to be hollowed out into a number of spaces, the mastoid cells, which exhibit the greatest possible variety as to their size and number. At the upper and front part of the process, they are large and irregular and contain air, but toward the lower part, they diminish in size, while those at the apex of ...
Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
The radiograph for each mastoid is taken separately. Schuller's view serves as an alternate view to the Law projection which uses a 15° angle of patient's face toward the image receptor and a 15° caudal angulation of the computed radiography (CR) to achieve the same result, a lateral mastoid air cells view without overlap of the opposite side.
The mastoid portion is at first flat, with the stylomastoid foramen and rudimentary styloid immediately behind the tympanic ring. With air cell development, the outer part of the mastoid component grows anteroinferiorly to form the mastoid process, with the styloid and stylomastoid foramen now on the under surface.
The meningeal branch of the mandibular nerve (also known as the nervus spinosus) [1] is a sensory branch of the mandibular nerve (CN V3) that enters the middle cranial fossa through either the foramen spinosum or foramen ovale to innervate the meninges of this fossa as well as the mastoid air cells.
