The purposes of this study were to determine the prevalence of concha bullosa in patients with chronic sinusitis, to assess the origin of the pneumatisation (from the anterior or posterior ethmoid cells), and to evaluate the significance of the concha bullosa in the genesis of inflammatory sinus disease. We reviewed the CT studies of 308 patients with chronic sinusitis, assigning four grades of pneumatisation: absent, small, medium and large. Unilateral or bilateral concha bullosa was found in 164 patients (53%). In 79% of cases it was pneumatised via the posterior ethmoidal cells and in 21% via the anterior. A small concha bullosa was associated with abnormalities of the maxillary sinus, ethmoidal cells and ostiomeatal unit respectively in 49%, 28% and 34% of cases, whereas with a large concha bullosa the association was 55%, 36% and 41% respectively on the ipsilateral side and 55%, 32% and 41% on the contralateral side. The usually accepted hypothesis that the concha bullosa may contribute to the pathogenesis of inflammatory sinus disease seems doubtful.
本研究的目的是确定慢性鼻窦炎患者中泡状鼻甲的患病率，评估气化的起源（来自前筛窦或后筛窦气房），并评估泡状鼻甲在炎性鼻窦疾病发生中的意义。我们回顾了308例慢性鼻窦炎患者的CT研究，将气化分为四个等级：无、小、中、大。164例患者（53%）发现单侧或双侧泡状鼻甲。在79%的病例中，它通过后筛窦气房气化，21%通过前筛窦气房气化。小泡状鼻甲分别在49%、28%和34%的病例中与上颌窦、筛窦气房和窦口鼻道复合体异常相关，而大泡状鼻甲在同侧分别为55%、36%和41%，对侧分别为55%、32%和41%。泡状鼻甲可能导致炎性鼻窦疾病发病机制的通常接受的假设似乎值得怀疑。
