Subdural empyema is a rare but serious complication of paranasal sinusitis which may result in death or permanent disability in a significant proportion of cases. A case is presented in which displacement of a premolar root in the maxillary sinus led to a subdural empyema and a resultant left-sided hemiplegia. This case illustrates the necessity of early surgical intervention to remove displaced roots in the maxillary antrum in order to prevent the serious complications of paranasal sinusitis.
硬膜下积脓是鼻窦炎一种罕见但严重的并发症，在相当一部分病例中可能导致死亡或永久性残疾。本文报告一例上颌窦前磨牙牙根移位导致硬膜下积脓并继发左侧偏瘫的病例。该病例说明了早期手术干预以取出上颌窦内移位牙根以预防鼻窦炎严重并发症的必要性。
