Postoperative hearing improvement is measured as Air-Bone gap changes. Changes in bone conduction threasholds as a results of otosurgery is also discussed.
We discuss factors that have influence on bone conduction threasholds changes in individuals operated due to chronic otitis media.
The prospective analysis involves the patients operated on middle ear due to chronic infection in the Department of Otolaryngology at the Jagiellonian University of Krakow in the years 2010-2013. 457 otosurgeries were performed in this period of time.
293 first time operated on patients with chronic otitis media were analysed. Statistically significant bone conduction improvement was noticed after myringoplasty and in individuals with intact ossicular chain. No bone conduction threasholds improvement was observed with defects to the ossicles.
Unchanged mucous lining middle ear spaces and intact ossicular chain are crucial for bone conduction improvement after otosurgery. Scars, especially in round window, are poor prognostic factor for hearing improvement. Cleaning of the middle ear from granulation has an positive influence for bone conduction threasholds changes.
术后听力改善通过气骨导差变化来衡量。还讨论了耳外科手术导致的骨导阈值变化。
我们讨论了影响因慢性中耳炎接受手术的个体骨导阈值变化的因素。
前瞻性分析涉及2010年至2013年在克拉科夫雅盖隆大学耳鼻喉科因慢性感染接受中耳手术的患者。在此期间共进行了457例耳外科手术。
分析了293例首次接受慢性中耳炎手术的患者。鼓膜成形术后以及听骨链完整的个体中观察到了具有统计学意义的骨导改善。听骨链有缺损时未观察到骨导阈值改善。
中耳腔黏膜衬里未改变以及听骨链完整对于耳外科手术后骨导改善至关重要。瘢痕,尤其是圆窗处的瘢痕,是听力改善的不良预后因素。清除中耳内的肉芽对骨导阈值变化有积极影响。
