Auditory canal hemorrhage is usually a sign of a basal skull fracture. It is commonly unknown that this sign can also be a symptom of combined fracture of the external auditory canal and the mandibular condyle. In our investigations of patients with maxillofacial injuries we found in 15% of 197 fractures of the mandibular condyle within 3 years this combination. In sequence of these results there is a differential diagnostic need for an exact investigation to clear up these various causes in each case as first step toward an accurate therapy. The mechanism of these fractures, their etiology, and therapy are discussed with special reference to possible complications.20
耳道出血通常是颅底骨折的迹象。人们通常不知道，这一迹象也可能是外耳道与下颌髁联合骨折的症状。在我们对颌面部损伤患者的调查中，在3年内197例下颌髁骨折患者中，有15%发现了这种联合骨折情况。基于这些结果，作为准确治疗的第一步，在每种情况下都需要进行精确检查以明确这些不同病因，存在鉴别诊断的必要性。本文特别参考可能的并发症，讨论了这些骨折的机制、病因及治疗方法。
