Traumatic perilymph fistula is reported to be rare in infants because of the small size of the infant external meatus. We treated an infant with a traumatic perilymph fistula in the right ear. A metallic wire had penetrated the tympanic membrane. Horizontal-rotatory nystagmus was also observed. Computed tomographic images revealed dislocation of the ossicles. The perilymph fistula was closed under general anesthesia. The incus-stapes joint was separated and the footplate of the stapes was dislocated. Leakage of the perilymph fluid was apparent from the oval window and this fistula was closed with connective tissue. The perforation of the tympanic membrane was closed with temporal fascia. After surgery, the spontaneous nystagmus disappeared. The patient is under observation as an outpatient and is growing normally.
据报道，由于婴儿外耳道较小，创伤性外淋巴瘘在婴儿中较为罕见。我们治疗了一名右耳患有创伤性外淋巴瘘的婴儿。一根金属丝穿透了鼓膜。还观察到水平旋转性眼球震颤。计算机断层扫描图像显示听小骨脱位。在外耳道瘘在全身麻醉下闭合。砧镫关节分离，镫骨足板脱位。外淋巴液从椭圆窗明显渗漏，该瘘管用结缔组织封闭。鼓膜穿孔用颞肌筋膜封闭。手术后，自发性眼球震颤消失。该患者作为门诊病人接受观察，生长正常。
