Aim:
To study the computed tomography (CT) features of pneumatized inferior turbinate (PIT).
Materials And Methods:
A retrospective review of paranasal sinus CT over a period of 12 years showed 16 cases of PIT. The pneumatization pattern was analysed according to the classification proposed by Bolger. Pneumatization was classified into three types: bulbous, lamellar, and extensive.
Results:
Fourteen patients had unilateral and two patients had bilateral pneumatization (n=18). Seven (39%) of the 18 PIT were bulbous, nine (50%) were lamellar, and two (11%) were of the extensive type. In eight (44%) cases there was communication between the medial wall of the maxillary sinus and the PIT.
Conclusions:
The features of PIT can be readily identified on CT. Imaging helps clinicians to differentiate PIT from other causes of the inferior turbinate hypertrophy or complications.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
