<p class="abstract"><strong>Background:</strong> The role of chronic inflammatory disease of the middle ear as a cause of sensory neural hearing loss (SNHL) is still debatable. Therefore, the role of this study to see if there is a relation between SNHL and duration of chronic supportive otitis media (CSOM), socio-economic (SE) status and age of patient.</p><p class="abstract"><strong>Methods:</strong> The hospital based case series study was conducted on all CSOM patients coming to ENT out-patient department in S. Nijalingappa Medical College and Hanagal Shri Kumareshwar (HSK) Hospital, Bagalkot, Karnataka over a period of one and a half years. After clinical examination, hearing evaluation was done using PTA as main tool.</p><p class="abstract"><strong>Results:</strong> Based on the present study, overall proportion of patients with SNHL was 20.66%. No relation of SNHL was found between sex and SE status of patient. No relation was found between severity of SNHL and age of patient. No relation was found between severity of SNHL and duration of CSOM. This present study shows that patients with CSOM with increased age have a greater chance of developing SNHL. Also, as the duration of CSOM increases there is a greater chance to develop SNHL.</p><p class="abstract"><strong>Conclusions:</strong> This study shows that the chance of developing SNHL in CSOM increases with age and disease duration. Hence, we can conclude that CSOM should be treated appropriately as early as possible to reduce the risk of developing SNHL in patients with CSOM.</p>
<p class="abstract"><strong>Background:</strong> As hearing impairment is a hidden disability, it is usually detected after 2-3 years by which time there will be irreversible stunting of the skills and hence rehabilitation procedures like hearing aids, speech therapy are unable to ensure complete development of speech. Therefore hearing impairment should be diagnosed as early as 6 months to ensure timely therapy. The objective of the study is to identify the proportion of incidence of hearing impairment in neonates using transient evoked otoacoustic emissions (TEOAE) as a screening tool.</p><p class="abstract"><strong>Methods:</strong> Prospective study on 800 newborns in a tertiary hospital using TEOAE. Brain stem evoked response audiometry (BERA) was used to confirm hearing loss in neonates who failed TEOAE. </p><p class="abstract"><strong>Results:</strong> Thirteen out of 800 newborns failed TEOAE test on first screening. Two failed on 2<sup>nd </sup>TEOAE test done after 3-4 weeks. Hearing loss was later confirmed in them with BERA test.</p><strong>Conclusions:</strong> Proportion of hearing loss in our study was 0.25%. Hearing screening should be done as early as possible so that deaf children are rehabilitated early.
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.
