The paranasal sinuses of 20 consecutive young adult patients with a complete Bell's palsy were investigated by magnetic resonance imaging (MRI) to obtain more information on the etiology of the disease. A high signal intensity on T2-weighted MRI was demonstrated in the paranasal sinuses, mainly the maxillary sinuses, in 12 of 20 (60%) patients in the early stage of Bell's palsy. Eleven of the 12 patients with positive MRI were followed up after 2 to 8 months (median 3 months), and in six of these, the bright signal intensity had disappeared, in two patients there was a regress, and in three patients the signal changes were persistent. The MRI findings indicate that transient inflammatory paranasal sinus disease, which may be caused by a viral and/or bacterial infection, infrequently may be associated with Bell's palsy. However, the relationship to the pathophysiologic process in Bell's palsy is still uncertain.
对20例连续的完全性贝尔麻痹青年成年患者的鼻窦进行磁共振成像（MRI）检查，以获取更多关于该疾病病因的信息。在贝尔麻痹早期，20例患者中有12例（60%）鼻窦，主要是上颌窦，在T2加权MRI上显示高信号强度。12例MRI阳性患者中的11例在2至8个月（中位时间3个月）后进行了随访，其中6例患者的明亮信号强度消失，2例患者信号强度减退，3例患者信号改变持续存在。MRI结果表明，短暂性炎性鼻窦疾病可能由病毒和/或细菌感染引起，很少与贝尔麻痹相关。然而，其与贝尔麻痹病理生理过程的关系仍不确定。
