The role of auditory tube function in mastoid pneumatization
has been controversial.
Pneumatized superior turbinate: Pneumatization
of superior turbinate can occur from posterior ethmoid cells.
The degree of pneumatization
of the sphenoid sinus may vary considerably.
(2.) Tos M: Mastoid pneumatization
, a critical analysis of the hereditary theory.
This cell represents pneumatisation of the inter-frontal sinus septum; when extensive, such pneumatization
can extend into the crista galli.
of these structures is clinically significant when it causes obstruction to airflow or to sinus drainage and ventilation.
(1) Regardless of the etiology, extensive pneumatization
of the sphenoid sinus into the pterygoid process is consistently seen.
However, failure of the brain to grow causes other structures in the calvaria to grow inwards, accounting for hyper pneumatization
of ipsilateral sinuses, increased width of the diploic space, elevations of the greater wing of the sphenoid as well as the petrous ridge, shift of midline structures towards ipsilateral side and the sulcal prominence is absent.
These anomalies have included pneumatization
, agenesis, and.
Otomicroscopy with suction clearance was also performed in all cases before the surgery to confirm the otoscopic findings, to clear any discharge and X-ray mastoid-Schuller's view of both mastoid was taken in all the cases to rule out any associated mastoid pathology and to look for the pneumatization
of the middle ear begins at week 29 and continues to week 34, when the process expands posteriorly to form the mastoid antrum.
However its exact location depends on several factors, including site of attachment of uncinate process, pneumatization
of several other cells that drain into frontal recess (e.g.
