A case of traumatic incudostapedial joint dislocation with stapes footplate into the vestibular window and pneumolabyrinth patient history. Patients mainly presented with vertigo, hearing loss in the left ear, audible sound when the head was shifted to the left, and subsequent vertigo, manifested as a spiral rotation, accompanied by gait instability, a feeling of stepping on cotton, and decreased attention. Pure tone audiometry showed mixed hearing loss in the left ear and temporal bone CT demonstrated air density in the left vestibule. Then, the patient underwent exploratory tympanotomy, which found the incudostapedial joint dislocation and stapes footplate into the vestibular window. According to the patient's history of head trauma, temporal bone CT, and exploratory tympanotomy can be diagnosed as: pneumolabyrinth, traumatic ossicular injury.
1例外伤性砧镫关节脱位伴镫骨足板陷入前庭窗及气迷路患者病史。患者主要表现为眩晕、左耳听力损失、头部向左转动时可听到声音及随后出现眩晕，表现为螺旋式旋转，伴有步态不稳、踩棉花感及注意力下降。纯音听力测定显示左耳混合性听力损失，颞骨CT显示左前庭有气体密度影。随后，患者接受了探查性鼓室切开术，发现砧镫关节脱位及镫骨足板陷入前庭窗。根据患者头部外伤史、颞骨CT及探查性鼓室切开术可诊断为：气迷路、外伤性听骨链损伤。
