Abstract

Aims: The present study was designed to compare the threshold estimation with Auditory brainstem responses (ABRs) using two stimuli, click and LS CE-Chirp and behavioral thresholds in men with noise induced hearing loss (NIHL).

Materials and methods: The ABR test was performed for 32 men, with a mean age of 36.06 years and moderate hearing loss in high frequencies. Threshold was considered as the lowest intensity at which wave V could be identified and reproduced in two repeated measurements. For data analysis, Wilcoxon test was used for comparing the thresholds obtained from the two stimuli and spearman's test assessed the relationship between behavioral thresholds and those recorded by two stimuli.

Results: The mean wave V threshold for the LS CE-Chirp stimulus was significantly lower than that for the click stimulus (P-value = 0.001). Also, there was a significant positive correlation between the threshold of two stimuli with the behavioral threshold of 1000 to 4000 Hz (P-value = 0.001). However, the correlation of behavioral threshold with LS CE-Chirp was higher than the Click stimulus in the 500 to 3000 Hz.

Conclusions: The present study demonstrated that threshold estimation with LS CE-Chirp stimulus can be obtained with a higher correlation and smaller difference from behavioral threshold in mid and low frequencies. Therefore, LS CE-Chirp can be used as a valuable stimulus for more accurate threshold estimation in individuals with noise induced hearing loss who do not cooperate in conventional pure-tone audiometry and referred to otolaryngologists for forensic follow-ups related to compensation claims.

成人噪声性听力损失的咔哒声和LS CE-Chirp刺激阈值估计与行为阈值的比较。

目的：比较噪声性听力损失（NIHL）男性患者的咔哒声和LS CE-Chirp两种刺激下的阈值估计与听觉脑干反应（ABRs）的差异。材料与方法：对32例男性进行ABR测试，平均年龄36.06岁，高频中度听力损失。阈值被认为是在两次重复测量中可以识别和再现波V的最低强度。数据分析采用Wilcoxon检验比较两种刺激所得阈值，spearman检验评估两种刺激所得行为阈值之间的关系。结果：LS CE-Chirp刺激的平均波V阈值显著低于click刺激（p值= 0.001）。两种刺激阈值与1000 ~ 4000 Hz的行为阈值存在显著正相关（p值= 0.001）。而行为阈值与LS CE-Chirp在500 ~ 3000 Hz范围内的相关性高于Click刺激。结论：本研究表明，LS CE-Chirp刺激的阈值估计与行为阈值在中低频具有较高的相关性和较小的差异。因此，LS CE-Chirp可以作为一种有价值的刺激，用于更准确地估计噪声性听力损失个体的阈值，这些个体不配合传统的纯音测听，并提交耳鼻喉科医生进行与赔偿索赔相关的法医随访。

期刊介绍： Indian Journal of Otolaryngology and Head & Neck Surgery was founded as Indian Journal of Otolaryngology in 1949 as a scientific Journal published by the Association of Otolaryngologists of India and was later rechristened as IJOHNS to incorporate the changes and progress. IJOHNS, undoubtedly one of the oldest Journals in India, is the official publication of the Association of Otolaryngologists of India and is about to publish it is 67th Volume in 2015. The Journal published quarterly accepts articles in general Oto-Rhino-Laryngology and various subspecialities such as Otology, Rhinology, Laryngology and Phonosurgery, Neurotology, Head and Neck Surgery etc. The Journal acts as a window to showcase and project the clinical and research work done by Otolaryngologists community in India and around the world. It is a continued source of useful clinical information with peer review by eminent Otolaryngologists of repute in their respective fields. The Journal accepts articles pertaining to clinical reports, Clinical studies, Research articles in basic and applied Otolaryngology, short Communications, Clinical records reporting unusual presentations or lesions and new surgical techniques. The journal acts as a catalyst and mirrors the Indian Otolaryngologist’s active interests and pursuits. The Journal also invites articles from senior and experienced authors on interesting topics in Otolaryngology and allied sciences from all over the world. The print version is distributed free to about 4000 members of Association of Otolaryngologists of India and the e-Journal shortly going to make its appearance on the Springer Board can be accessed by all the members. Association of Otolaryngologists of India and M/s Springer India group have come together to co-publish IJOHNS from January 2007 and this bondage is going to provide an impetus to the Journal in terms of international presence and global exposure.
