概括

专利的 tympanostomy 管 (TT) 显著影响正常听力儿童的耳声排放 (OAE) 测试. 缺席的OAE是常见的,即使在专利管中也是如此,这表明在OAE解释时要谨慎.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
听力学听力学是指听力学.
儿科医学儿科医学

背景情况:

tympanostomy管 (TT) 在儿科耳鼻喉学中很常见.
专利TT对正常纯音声声度 (PTA) 患者的耳声声学排放 (OAE) 的影响需要评估.

研究的目的:

评估专利 tympanostomy 管 (TT) 对耳声排放 (OAE) 结果的影响.
为了确定TTs是否影响OAE结果在正常听觉的儿科患者中.

主要方法:

对具有专利TT的儿科患者的回顾性审查.
术后听力测量和OAE在1,2,4和8kHz的分析.
排除具有PTA>20dB或非专利TT的耳朵;OAE根据信号与噪声比分级别.

主要成果:

分析了124名患者 (217个耳朵),OAE测试的平均时间为手术后4.5个月.
观察到OAE缺失的高率:1kHz时为85%,2kHz时为57%,4kHz时为56%,8kHz时为83%.
78.8%的患者至少一次OAE频率失败,尽管正常的PTA和专利TT.

结论:

缺席的OAE在特异性TT患者中很常见,特别是在1和8kHz.
专利TT似乎直接影响OAE结果,即使是正常听力.
临床医生应谨慎解释OAE在具有专利TT的患者中;对OAE实用性的进一步研究是有必要的.

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
