A retrospective study of computed tomography scans of the paranasal sinuses of 131 control subjects in Hong Kong revealed minor mucosal abnormalities in more than half of the ethmoid sinuses. Major abnormalities were present in seven per cent of maxillary, five per cent of anterior ethmoid and four per cent of posterior ethmoid sinus. In 85 patients with nasopharyngeal carcinoma the prevalence of minor mucosal abnormalities in the sinuses was similar to that of the control group but major mucosal abnormalities were significantly more common in the anterior and posterior ethmoids at 15 per cent and 21 per cent of the respective sinuses (p < 0.001).
一项针对香港131名对照受试者鼻窦计算机断层扫描的回顾性研究显示，超过半数的筛窦存在轻微黏膜异常。上颌窦有7%、前筛窦有5%、后筛窦有4%存在严重异常。在85例鼻咽癌患者中，鼻窦轻微黏膜异常的发生率与对照组相似，但前筛窦和后筛窦的严重黏膜异常明显更为常见，分别占各自鼻窦的15%和21%（p<0.001）。
