摘　　要：目的提示传导性听力损失的患者不能只考虑外耳、中耳的病变。方法对听力学检查发现的2例表现为传导性听力损失的患者进行CT检查。结果CT检查发现1例为前庭水管扩大，另1例为上半规管裂综合征。结论对有传导性听力损失，特别是伴有如耳鸣、眩晕等内耳症状的患者，需要借助影像学等检查进一步排除内耳病变。Objective To discuss the fact that external and middle ear diseases are not the only etiologies of conductive hearing loss. Methods Two patients diagnosed with conductive hearing loss by hearing test underwent the CT scan. Results The CT results showed one case had large vestibular aqueduct （LVA） and the other superior semicircular canal dehiscence syndrome （SSCD）. Conclusion The patients with conductive hearing loss, especially those accompanied by tinnitus and vertigo, are supposed to receive the further examination such as imaging test to exclude the inner ear diseases.
