To describe a case of pneumolabyrinth secondary to tympanic membrane/ossicular trauma and the subsequent recovery of sensorineural hearing loss managed with conservative measures.
A 15-year-old boy presented to an outside hospital with signs and symptoms of acute hearing loss, vertigo, and tinnitus after penetrating injury to his right tympanic membrane. In addition, computed tomography demonstrated air density within the vestibule.
The patient was managed conservatively with bed rest, avoidance of straining, corticosteroids, and antibiotics.
Computed tomography, audiologic testing.
Patient recovered near-normal hearing subjectively. There was closure of the air-bone gap (<or=20 dB) along with resolution of air within vestibule.
We presented a case of a patient with pneumolabyrinth secondary to penetrating trauma to his tympanic membrane. With supportive treatment, air within the labyrinth resorbed, and the patient recovered sensorineural function. Comparing with the mixed successes of surgical repairs, we propose that initial management for traumatic pneumolabyrinth should be first treated conservatively in the absence of worsening symptoms.
描述一例因鼓膜/听骨链创伤继发的中耳迷路积气病例，以及随后采用保守措施治疗感音神经性听力损失并实现恢复的情况。
一名15岁男孩因右鼓膜穿透伤后出现急性听力损失、眩晕和耳鸣的症状及体征，就诊于外院。此外，计算机断层扫描显示前庭内有气体密度影。
患者接受了保守治疗，包括卧床休息、避免用力、使用皮质类固醇和抗生素。
计算机断层扫描、听力测试。
患者主观上听力恢复至接近正常。气骨导间距缩小（≤20dB），同时前庭内气体消失。
我们报告了一例因鼓膜穿透伤继发中耳迷路积气的患者。通过支持性治疗，迷路内的气体被吸收，患者恢复了感音神经功能。与手术修复的不同成功率相比，我们建议对于创伤性中耳迷路积气，在症状未恶化的情况下，初始治疗应首先采用保守治疗。
