Aeration of the middle turbinate, termed "concha bullosa," is a common anatomical variant of intranasal anatomy. Of 320 patients evaluated for sinus disease with coronal CT, 34% had concha bullosa on at least one side. The overall incidence of inflammatory disease in the ostiomeatal complex in these symptomatic patients was not different between those with and without concha bullosa. However, there were many cases in which an abnormally large middle turbinate appeared to obstruct the ostiomeatal complex causing secondary infection of the ethmoid, frontal, and maxillary sinuses. Obstruction of drainage of the concha bullosa itself can lead to mucocele formation. Furthermore, the presence of a concha bullosa has important implications for the technique of endoscopic surgery used in the management of the sinus disease. The anatomy, pathophysiology, and CT findings in patients with concha bullosa are reviewed.
中鼻甲气化，即所谓的“泡状鼻甲”，是鼻内解剖结构中一种常见的解剖变异。在320例接受鼻窦疾病冠状位CT评估的患者中，34%至少一侧存在泡状鼻甲。在这些有症状的患者中，有泡状鼻甲和没有泡状鼻甲的患者在窦口鼻道复合体炎症性疾病的总体发生率上没有差异。然而，有许多病例显示，异常增大的中鼻甲似乎阻塞了窦口鼻道复合体，导致筛窦、额窦和上颌窦继发感染。泡状鼻甲本身引流受阻可导致黏液囊肿形成。此外，泡状鼻甲的存在对鼻窦疾病治疗中使用的内镜手术技术具有重要意义。本文综述了泡状鼻甲患者的解剖结构、病理生理学及CT表现。
