We herein report a case of traumatic fracture of the stapes accompanying vestibular window rupture with perilymph fistula, and its diagnosis and surgical procedure were discussed. In the present case, a direct force through the external auditory canal damaged not only the ossicular chain but also the vestibular window. On the exploratory tympanotomy, the complete dislocation and fracture of the stapes with a relatively huge rupture was confirmed. Perilymph fistula was repaired with a connective tissue graft, which was inserted between disrupted vestibular window and the long process of the incus. Vestibular dysfunctions disappeared within 3 days, and a satisfactory audiologic result was obtained one month after surgery.
我们在此报告一例伴有前庭窗破裂和外淋巴瘘的镫骨外伤性骨折病例,并对其诊断和手术过程进行了讨论。在本病例中,通过外耳道的直接外力不仅损伤了听骨链,还损伤了前庭窗。在探查性鼓室切开术中,证实镫骨完全脱位并骨折,伴有相对较大的破裂。用结缔组织移植物修复外淋巴瘘,将其插入破裂的前庭窗和砧骨长突之间。前庭功能障碍在3天内消失,术后1个月获得了满意的听力结果。
