Concha bullosa (CB) is a pneumatic cavitation inside a concha in the nasal cavity. It is one of the most widely recognized nasal variations and is mostly found in the middle concha. CB is divided according to its site into three types; lamellar, bulbous and extensive. The goal of our study was to estimate the prevalence of CB among Saudi adult population and its association with sinusitis by using multidetector computed tomography (MDCT). This was a retrospective study carried out over a three-year period on 879 adult Saudi patients aged 18 years or older, referred for MDCT assessment of paranasal sinuses. Males were 540 and females were 339. Patients with facial congenital anomalies or nasal trauma were excluded from our study. CB was prevalent in both males and females among Saudi population (55.4%, 55.7%) respectively. Bilateral CB (55.5%) was more frequent than unilateral (44.5%). Extensive CB (44.0%) was the most frequent type. Sinusitis was associated more in patients with CB (48.0%) versus those who have no CB (5.9%). In conclusion, CB was prevalent among Saudi population and the most frequently recorded is the extensive type. Furthermore, the most common type associated with sinusitis was extensive CB (49.6%).
泡状鼻甲（CB）是鼻腔中甲腔内的一种气腔化现象。它是最广为人知的鼻腔变异之一，多见于中鼻甲。CB根据其部位分为三种类型：片状、球茎状和广泛型。我们研究的目的是通过使用多排螺旋计算机断层扫描（MDCT）来估计沙特成年人群中CB的患病率及其与鼻窦炎的关联。这是一项为期三年的回顾性研究，研究对象为879名18岁及以上的沙特成年患者，这些患者因鼻窦的MDCT评估而被转诊。男性540名，女性339名。面部先天性异常或鼻外伤患者被排除在我们的研究之外。沙特人群中男性和女性的CB患病率分别为55.4%和55.7%。双侧CB（55.5%）比单侧CB（44.5%）更常见。广泛型CB（44.0%）是最常见的类型。CB患者中鼻窦炎的关联度更高（48.0%），而无CB患者中鼻窦炎的关联度为5.9%。总之，CB在沙特人群中普遍存在，最常记录的类型是广泛型。此外，与鼻窦炎相关的最常见类型是广泛型CB（49.6%）。
