To study the computed tomography (CT) features of pneumatized inferior turbinate (PIT).
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.
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.
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.
研究气化下鼻甲（PIT）的计算机断层扫描（CT）特征。
回顾性分析12年间的鼻窦CT，发现16例PIT。根据Bolger提出的分类方法分析气化模式。气化分为三种类型：球型、板层型和广泛型。
14例患者为单侧气化，2例为双侧气化（共18例）。18例PIT中，7例（39%）为球型，9例（50%）为板层型，2例（11%）为广泛型。8例（44%）病例中，上颌窦内侧壁与PIT之间存在连通。
PIT的特征在CT上易于识别。影像学检查有助于临床医生将PIT与下鼻甲肥大的其他原因或并发症相鉴别。
