慢性化脓性中耳炎术前检查指标和听骨链状态的相关性分析

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。

Analysis of preoperative findings and ossicular condition in chronic suppurative ctitis media

Objective:To discussion the relationship of preoperative findings and ossicular condition in chronic suppurative otitis media.Method:The correlation between the ossicular conditions and classification of tympanic membrane perforation, ear discharge, air conduction pure tone average, air-bone gap, pneumatization, complication, and cholesteatoma in 251 patients(288 ears) with chronic suppurative otitis media was analysed.Result:The air-conduction threshold and air-bone gap in patients with ossicular discontinuity are higher than that in patients with ossicular continuity. Ossicular discontinuity in patients with perforation of the pars flaccida of tympanic membrane, persistently draining ears, complications, and cholesteatoma occurred significiantly more frequently than those without these conditions.Conclusion:The air-conduction threshold and air-bone gap are the more reliable indications to identify the ossicular conditions in patients with chronic suppurative otitis media. There are significiant correlation between the ossicular conditions in patients with chronic otitis media and their classification of tympanic membrane perforation, ear discharge, complication, and cholesteatoma.
