Preoperative, operative and postoperative findings in 97 cases of labyrinthine fistula are presented. The majority of patients had had symptoms of chronic otitis media for 20 years or more and manifested some degree of sensorineural hearing impairment. Two-thirds had experienced dizziness. The fistula was limited to the lateral semicircular canal in 83 cases and involved the labyrinth more extensively in 14 instances. The intact canal wall technique was used in less than 60% and an open cavity technique in a quarter of the cases. Severe or total sensorineural hearing impairment developed postoperatively in 8% of the lateral canal cases and in over half of the extensive fistula cases. Five per cent had incapacitating dizziness for up to 6 months postoperatively. When a labyrinthine fistula is encountered in an only hearing ear, a classified modified radical mastoidectomy is usually recommended. In other instances, the procedure performed will vary with the status of the opposite ear, the extent of the fistula, the sensorineural function of the involved ear and the size of the mastoid.
本文介绍了97例迷路瘘管患者的术前、术中及术后情况。大多数患者有20年或更长时间的慢性中耳炎症状，并表现出一定程度的感音神经性听力损失。三分之二的患者有过头晕症状。83例患者的瘘管局限于外侧半规管，14例患者的迷路受累范围更广。不到60%的病例采用了完整外耳道壁技术，四分之一的病例采用了开放乳突腔技术。外侧半规管瘘管病例术后出现严重或完全性感音神经性听力损失的比例为8%，广泛瘘管病例术后这一比例超过一半。5%的患者术后出现长达6个月的致残性头晕。当在仅存听力的耳中发现迷路瘘管时，通常建议行改良乳突根治术。在其他情况下，所采取的手术方式将根据对侧耳的情况、瘘管的范围、患耳的感音神经功能以及乳突的大小而有所不同。
