本病例表明，上半规管开裂综合征可能与“伪”传导性听力损失有关，这种症状与耳硬化的临床表现重叠。我们提出的情况下，一个48岁的德国白人妇女提出听力损失在左侧和眩晕。为了改善听力，她曾做过三次镫骨切除术。重新格式化的高分辨率计算机断层扫描和患者的病史证实了并发管开裂综合征的诊断。耳硬化手术后听力改善失败可能提示另一种潜在的诊断，应通过进一步适当的评估来探索。
This case illustrates that superior semicircular canal dehiscence syndrome can be associated with a "pseudo"-conductive hearing loss, a symptom that overlaps with the clinical appearance of otosclerosis. We present the case of a 48-year-old German Caucasian woman presenting with hearing loss on the left side and vertigo. She had undergone three previous stapedectomies for hearing improvement. Reformatted high-resolution computed tomographic scanning and the patient's history confirmed the diagnosis of concurrent canal dehiscence syndrome. Failure of hearing improvement after otosclerosis surgery may indicate an alternative underlying diagnosis which should be explored by further appropriate evaluation.
