Abstract
The use of PLDs is linked to negative effects on the inner ear. Thus, the aim of this study is to identify the optimal frequency to test cVEMP in individuals using PLDs. A cross sectional comparative study was conducted on 128 individuals who were between the ages of 15-24 years with PLD exposure were divided into two groups: control group (history of PLD exposure for at least 1 h per day at a volume less than 60% of the PLD) and an experimental group (history of PLD exposure for at least 1 h per day at a volume greater than 60% for more than 1 year). Participants underwent MIRE and cVEMP testing using tone bursts of three different frequencies (500, 750, and 1000 Hz). Further, Latency, Peak-Peak Amplitude and Asymmetric Ratio of cVEMP responses were compared between the two groups. The data were analyzed using statistical tests such as Mann-Whitney U test and Kruskal-Walli's test. The findings revealed no statistically significant difference across frequencies in both groups. However, experimental group used higher output dBA values (75.4 ± 7.77 dBA). Similarly, reduced amplitudes, increased latencies and Asymmetric Ratio values were observed in experimental group suggesting a negative influence of PLDs on the vestibular system. A 500 Hz tone burst stimuli is observed to be the optimal frequency for cVEMP. However, higher values for all compared parameters of cVEMP in experimental group may depict the negative influence of PLD on the vestibular system.
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.
