Amongst the acquired factors, chronic otitis media has been significantly seen to be associated with a poor pneumatization of the mastoid air cell system (Pakira et al.; Arora et al.; Shea et al., 1990).
Agger Nasi Cells: We found pneumatization of the agger nasi cells in 58(72.5%) nasal cavities.
At surgery, extensive pneumatization of the left ethmoid sinus was encountered inferiorly (figure, C).
To better define this anatomy, 20 sphenoid sinuses in cadavers were dissected to reveal important anatomical relationships, dimensions, volume and pneumatization of the sphenoid sinus.
In a study by Sethi et al, in the normal ear, 84% had well pneumatized mastoid air cell system and 16% had poor pneumatization on x-ray.
A number of lesions and disease processes have been described within the petrous apex, including cholesterol granulomas, petrous apicitis, cerebrospinal fluid cysts, encephaloceles, epidermoids, effusions, mucoceles, carotid aneurysms, asymmetric pneumatization, chordomas, chondrosarcomas, metastases, paragangliomas (glomus tumors), meningiomas, and schwannomas, (1-8) Characteristic presenting symptoms, as well as findings on magnetic resonance imaging (MRI) and computed tomography (CT) scans, are essential for differentiation of the lesion.
These cells represent pneumatization of the orbital plate of the frontal bone posterior to the frontal recess and the frontal sinus.
Pneumatization of nasal structures is well described.
Pneumatization of the mastoid process begins between the last month of gestation and birth, with continued growth well into adolescence.
Computed tomography (CT) showed extensive pneumatization of the sphenoid sinus into the pterygoid process (figure 1).
Schuler's view X-ray mastoid showed loss of pneumatization of right mastoid region.
The hypertrophy of the right middle turbinate in this case was not due to a concha bullosa, as evidenced by the middle turbinate's lack of pneumatization. It appears that because this patient's nasal septum was markedly deflected to the left, hence enlarging the right airway artificially over the previous 35 years, the right middle turbinate had an unusually large space in which to expand.
