目的：描述3例中耳穿透伤后的气胸，并回顾以前报道的病例，比较诱发因素和听力结果。数据来源：我们遇到的3例病例和PubMed和日本医学文摘协会数据库。研究选择：除了我们的3例病例，我们从41篇关于气胸的文章中确定了48例病例。数据提取：资料综合：在51例肺气肿患者中，16例患者的听力学检查结果无法提供。在其余35例病例中，分析了听力结局，重点关注3个因素：1）医疗干预的差异和间隔，2）存在镫骨病变，3）气泡延伸到内耳。我们没有发现任何显着差异的干预措施，虽然手术后不到2周受伤后往往与更高的听力恢复率（54%）比手术后2周或更长时间受伤（25%）。局限于前庭或半规管的23例患者中，11例（48%）听力改善，6例（0%）前庭器官至耳蜗的患者听力均未恢复。结论：评估气胸的位置和范围对预测听力预后和制定中、内耳外伤的治疗方案具有重要意义。
Objective: To describe 3 cases of pneumolabyrinth after penetrating injury to the middle ear and to review previously reported cases, comparing precipitating factors and hearing outcomes.Data Sources: Three cases we encountered and the PubMed and Japan Medical Abstracts Society databases.Study Selections: In addition to our 3 cases, we identified 48 cases from 41 articles regarding pneumolabyrinth.Data Extractions: All articles describing cases of pneumolabyrinth were used for this review.Data Synthesis: Among the 51 cases, audiologic evaluation was not available in 16 cases. In the remaining 35 cases, hearing outcomes were analyzed focusing on 3 factors: 1) differences in and interval until medical intervention, 2) existence of stapes lesions, and 3) extension of air bubble into the inner ear. We failed to find any significant differences in interventions, although operation less than 2 weeks after injury tended to be associated with a higher rate of hearing recovery (54%) than operation 2 weeks or longer after injury (25%). Furthermore, 11 (48%) of 23 cases with pneumolabyrinth limited to the vestibule or semicircular canals showed improved hearing, whereas none of 6 cases (0%) with pneumolabyrinth extending from the vestibular organs to the cochlea showed hearing recovery. This difference was statistically significant (p < 0.05).Conclusion: Assessment of the location and extension of pneumolabyrinth appears important in predicting hearing outcomes and planning the management of middle and inner ear trauma.
