目的:探讨慢性化脓性中耳炎术前检查指标和听骨链状态的相关性。方法:回顾性分析251例(288 耳)慢性化脓性中耳炎患者的听骨链状态与鼓膜穿孔类型、术前是否干耳、气导阈值、骨气导差值、乳突汽化程度、 耳源性并发症及胆脂瘤之间的相关性。结果:听骨链中断患者的气导阈值和骨气导差值明显增加;鼓膜松弛部穿 孔、术前持续流脓、存在胆脂瘤耳以及出现并发症耳的听骨链中断发生率明显增加。结论:根据纯音听阈可大致 判断听骨链的完整性和活动度;同时,听骨链状况与鼓膜穿孔类型、术前是否干耳、胆脂瘤耳和耳源性并发症耳具 有明显相关性。
Objective: To investigate the correlation between preoperative examination indexes and ossicular chain status of chronic suppurative otitis media. Methods: The ossicular chain status, tympanic membrane perforation type, preoperative dry ear, air conduction threshold, difference of air conduction, mastoidization degree, otogenic complications were retrospectively analyzed in 251 cases (288 ears) of chronic suppurative otitis media Symptoms and the relationship between cholesteatoma. Results: The air conduction threshold and the difference of air conduction were significantly increased in the patients with ossicular chain interruption. The perforation of the tympanic membrane lamellae, persistent pus preoperatively, the presence of cholesteatoma and the occurrence of complications of ossicular chain disruption were significantly increased. Conclusion: According to the threshold of pure tone, the integrity and activity of the ossicular chain can be roughly estimated. At the same time, the condition of the ossicular chain and the type of perforation of the tympanic membrane, whether the ear is dry, the ear of the cholesteatoma and the ear of the ear are significantly correlated .
