Abstract

Background: Severe-to-profound sensorineural hearing loss (SNHL) is a significant impediment to an individual's ability to communicate successfully. If hearing loss occurs prior to the development of speech, additional reading and language difficulties confront the indi¬vidual. Although postlingual hearing loss does not necessarily affect speech and language development, it can also have a profoundly negative impact on a person's ability to function. The successful applica¬tion of cochlear implantation in children and adults with severe-to-profound SNHL has been pivotal in helping overcome these functional deficits. This chapter reviews various etiologies of severe-to-pro¬found SNHL, highlights aspects involved in patient evaluation, and discusses potential management options for rehabilitation. Particular focus is given to the role of cochlear implants in the management of patients with severe-to-profound SNHL. Materials: Total 46 Children were enrolled in my study, and hearing level was examined by audiometry on first day then 1 week, and 3 months interval, According to the degree of the initial hearing loss. All children’s were attending on OPD& IPD in the department of ENT in Darbhanga Medical College & Hospital. Results: The criteria used to determine cochlear implant candidacy have evolved fairly rapidly over the past several years. At present, pure-tone averages should exceed 70 dB sound pressure level, whereas word¬ recognition scores should be less than 50% in the best-aided condition using the Hearing in Noise Test or comparable testing methods. As discussed, a trial of appropriate amplification should be undertaken before using a cochlear implant. Additional criteria include inner ear anatomy amenable to receiving a cochlear implant, a lack of medical contraindica¬tions, appropriate patient/family expectations and support, ear free of active infection, and age older than 12 months. As implant technology improves, indications for cochlear implantation will expand to include those with better residual hearing. Conclusion: It is important to recognize that the use of cochlear implants has been transformational. Within the pediatric population, early use of cochlear implants has allowed language development equivalent to that of hearing children and has provided hearing¬impaired children an opportunity to participate and thrive in mainstream educational settings. Cer¬tainly, there is great individual variability among cochlear implant users, and it is difficult to prog-nosticate expected outcomes for anyone potential candidate. Nevertheless, there is growing evidence that the average cochlear implant user will benefit greatly from the use of this device.
