Methods: 122 cases (122 ears) of unilateral cholesteatoma otitis media were treated by mastoidectomy and/or tympanoplasty plus stage I tympanoplasty, and tragus cartilage ring-cartilage membrane (Referred to as cartilage group, 62 ears) and temporalis muscle fascia (Referred to as fascia group, 60 ears) were used as tympanic membrane grafts respectively. The changes of bone conduction hearing threshold were compared between the two groups before and 1, 3, 6 months and 1, 3 years after operation. And compare the difference in the incidence of ossicular chain fixation or necrosis, vestibular window or cochlear window dysfunction between the two groups of patients with increased (positive) and decreased (negative) bone conduction threshold before operation. Results: Compared with the healthy side, 95 ears of 122 ears in the two groups had higher bone conduction hearing threshold before operation. Among them, 48 ears were in cartilage group and 47 ears were in fascia group;In 72 ears (76.34%) of these cases, the bone conduction hearing threshold decreased after operation, and the difference between the two groups was statistically significant (P Conclusion: The improvement of bone conduction hearing threshold in patients with cholesteatoma otitis media is mainly related to the fixation or necrosis of ossicular chain and the dysfunction of two windows. The tragus cartilage ring-perichondrium tympanoplasty can not only reduce the air-bone conduction difference, but also reduce the bone conduction hearing threshold, which has the advantage of stable and lasting hearing improvement.展开更多
目的探讨放射治疗对早期鼻咽癌患者骨导听阈的影响。方法收集2006年2月至2012年3月在我院治疗且资料完整的32例早期鼻咽癌患者,分别记录患者放疗前、放疗后1.5年及放疗后2年双耳0.5、1、2、4 k Hz四个语言频率骨导听阈值及畸变产物耳声...目的探讨放射治疗对早期鼻咽癌患者骨导听阈的影响。方法收集2006年2月至2012年3月在我院治疗且资料完整的32例早期鼻咽癌患者,分别记录患者放疗前、放疗后1.5年及放疗后2年双耳0.5、1、2、4 k Hz四个语言频率骨导听阈值及畸变产物耳声发射,并对记录的数据进行统计分析。结果患者双耳0.5、1、2、4 k Hz四个语言频率骨导阈值放疗后1.5年及放疗后2年均高于放疗前,且三者差异有统计学意义(P<0.05)。放疗后1.5年及放疗后2年患者DPOAE检查未通过率增高,且差异有统计学意义(P<0.05)。结论放疗可以使早期鼻咽癌患者骨导阈值提高,对于鼻咽癌放疗患者应尽早积极防治,避免感音神经性听力损失。展开更多
