On rare occasions, facial paralysis associated with a parotid tumor need not denote malignancy. We present two cases in which, contrary to appropriate conventional wisdom, facial paralysis resulted from benign mixed tumors. Each patient presented over 8 years following primary surgical excision. In neither patient was a mass palpable, and facial paralysis was the sole sign of recurrent disease. Each patient had been followed up for several months with a presumptive diagnosis of Bell's palsy prior to discovery of recurrent tumor by radiologic imaging. In each case, at operation the tumor was found to infiltrate the temporal bone via the stylomastoid foramen. Facial paralysis presumably resulted from extrinsic compression of the facial nerve. These two cases add to the few previous reports of facial paralysis due to benign parotid gland tumors.
在极少数情况下，与腮腺肿瘤相关的面神经麻痹并不一定意味着恶性。我们报告两例病例，与通常的合理认知相反，面神经麻痹是由良性混合瘤引起的。每位患者在初次手术切除后8年以上出现症状。两名患者均未触及肿块，面神经麻痹是复发性疾病的唯一体征。在通过放射影像学发现复发性肿瘤之前，每位患者都被诊断为贝尔麻痹并随访了数月。在每例病例中，手术时发现肿瘤通过茎乳孔浸润颞骨。面神经麻痹可能是由于面神经受到外部压迫所致。这两例病例补充了此前关于腮腺良性肿瘤导致面神经麻痹的少数报道。
