慢性化脓性中耳炎手术中患者听力受损的高危因素及防治对策

Risk factors and countermeasures of intraoperative hearing impaired in patients with chronic otitis media

目的探讨慢性化脓性中耳炎手术中患者听力受损的高危因素。方法回顾性分析150例慢性化脓性中耳炎手术患者的临床资料,对其中因手术中操作造成的听力受损患者进行危险因素分析。结果 150例慢性化脓性中耳炎患者手术中听力受损者17例,发生率为11.33%,其中锤骨柄、手术时间、咽鼓管功能、电钻噪声、后鼓室胆脂瘤、迷路瘘管、耳硬化症是慢性化脓性中耳炎手术中患者听力受损的危险因素,也是独立危险因素(P<0.05)。结论慢性化脓性中耳炎手术中听力受损相关因素较为复杂,在临床上要加强防范。

Objective To investigate the risk factors of intraoperative hearing impaired in patients with chronic otitis media . Methods 150 cases of chronic otitis media surgery were retrospectively analyzed on the risk factors of intraoperative hearing im‐paired .Results Among the 150 cases of patients with chronic otitis media ,there were 17 cases hearing impaired during the surger‐y ,and the incidence rate was 11 .33% .The malleus handle ,operative time ,pharynx tympanic membrane function ,drill noise ,chol‐esteatoma after getting lost fistula ,otosclerosis were the risk factors caused hearing impaired ,and they were independent risk fac‐tors （P〈0 .05） .Conclusion There are complex factors related with hearing impaired during chronic otitis media surgery ,and clinic should pay attention to it .
