The aim of this study was to determine the frequency and morphology of Haller cells using a new radiological technique that allows examination of the facial skull. In a single center retrospective cohort study the cone-beam computed tomography (CBCT) volume data of the maxillary sinus of 199 patients were analysed (398 paranasal sinuses). If Haller cells were found, their capacity was determined. If orthopantomograms (OPG) were taken in a narrow time frame around the CBCT investigation, the rate of correspondence of the radiological findings was determined. The correlation between frequency of Haller cells and age and gender was calculated. Out of 199 patients 47 showed at least one Haller cell (23.62%). The total number of Haller cells was 64. Correspondence was rare in the same case between the results from different examination procedures with respect to the target object. Bony variants of paranasal sinuses can be analysed using CBCT as an alternative to computed tomography (CT), whereas OPG images do not reliably detect Haller cells.
本研究的目的是使用一种可用于检查面颅骨的新放射技术，确定哈勒氏细胞的发生率和形态。在一项单中心回顾性队列研究中，分析了199例患者上颌窦的锥形束计算机断层扫描（CBCT）容积数据（398个鼻窦）。如果发现哈勒氏细胞，则确定其容积。如果在CBCT检查前后的短时间内拍摄了曲面体层摄影（OPG）片，则确定放射学检查结果的符合率。计算哈勒氏细胞发生率与年龄和性别的相关性。199例患者中，47例至少有一个哈勒氏细胞（23.62%）。哈勒氏细胞总数为64个。对于同一病例，不同检查程序针对目标对象的结果之间的符合率很低。鼻窦的骨质变异可以使用CBCT进行分析，作为计算机断层扫描（CT）的替代方法，而OPG图像不能可靠地检测到哈勒氏细胞。
