CSF otorrhea arising from defects in the tegmen and middle fossa dura may be congenital or acquired. It may be spontaneous or secondary to trauma, chronic ear disease, tumor or surgical treatment. In the six cases presented, the tegmen defect and associated CSF leak were secondary to chronic ear disease in two cases, to mastoid surgery in two cases, to temporal bone fracture and congenital origin in one case each. The successful management of these patients utilizing a mini-craniotomy in conjunction with mastoid surgery is described. Mini-craniotomy facilitates precise extradural, intracranial placement of an autogenous graft over the tegmen defect which can be technically difficult in the transmastoid approaches, yet avoids the morbidity and potential complications of a full middle fossa craniotomy. It does not significantly add to the length of the mastoid procedure or its complications.
由中颅窝硬脑膜和鼓室盖缺损引起的脑脊液耳漏可能是先天性的，也可能是后天获得性的。它可能是自发性的，也可能继发于外伤、慢性耳部疾病、肿瘤或外科治疗。在本文报道的6例病例中，鼓室盖缺损及相关脑脊液漏，2例继发于慢性耳部疾病，2例继发于乳突手术，1例继发于颞骨骨折，1例为先天性。本文描述了通过小型开颅术联合乳突手术成功治疗这些患者的情况。小型开颅术有助于在鼓室盖缺损处精确地在硬膜外、颅内放置自体移植物，而这在经乳突入路中技术上可能具有挑战性，但避免了全中颅窝开颅术的发病率和潜在并发症。它不会显著增加乳突手术的时长或并发症。
