Purpose The study aimed to investigate the effect of PCOS on high-frequency thresholds, speech perception in quiet and in presence of noise, and vestibular functioning in women with and without PCOS and to correlate the speech perception scores with that of the pure-tone thresholds obtained at conventional and higher frequencies. Methods Women with and without PCOS in the age range of 18–40 years diagnosed between January 2019 and January 2020 were participants. Conventional and high-frequency audiometry (HFA), speech perception in quiet and in noise (SPIN), and cervical vestibular-evoked myogenic potentials (cVEMP) and ocular vestibular-evoked myogenic potentials (oVEMP) were assessed for both groups. Results Conventional audiometry (250 Hz to 8000 Hz) showed no statistically significant difference between both groups. High-frequency audiometry (9000 Hz to 20,000 Hz) showed significantly poorer pure-tone thresholds for women with PCOS compared to women without PCOS. SPIN results showed significantly lower SPIN scores for women with PCOS for − 3dB SNR, − 6 dB SNR, and − 9dB SNR. No difference in scores was observed for quiet conditions and 0 dB SNR for women with and without PCOS. cVEMP and oVEMP responses showed reduced amplitude in women with PCOS. Conclusion All the women diagnosed with having PCOS should be screened for hearing loss, speech perception difficulty in quiet and in presence of noise, and vestibular system functioning. If the hearing is affected, intervention should be started early in life.
Background Children with sensorineural hearing loss (SNHL) form a major chunk of the population with hearing difficulty. Since the auditory system is close to the vestibular system and shares the common fluid, the abnormality in the auditory system might impair the functioning of the vestibular system. Main body of the abstract The present systematic review aimed at studying the application of cervical and ocular vestibular evoked myogenic potential responses (cVEMP and oVEMP) during assessment and rehabilitation of children with SNHL with and without a cochlear implant. A systematic search was done across databases on cVEMP and oVEMP findings in children with SNHL. Out of 92 articles retrieved, 21 articles were found to be appropriate as per our inclusion criteria. Significant vestibular abnormality was seen in children with SNHL as shown on cVEMP and oVEMP test reports. The cVEMP and oVEMP abnormalities seen were more in children with SNHL using a cochlear implant. Pre- and post-implantation studies showed a significant reduction in measures of cVEMP and oVEMP after implantation. Short conclusions Studies in the last decade reported abnormal cVEMP and oVEMP response in children with SNHL with and without cochlear implantation. cVEMP and oVEMP response is also associated with poor motor development in children with SNHL. Thus, emphasis should be given to assessing vestibular functioning in children with SNHL to rehabilitate them early in life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
