International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.43045
Abstract: Hearing loss in children constitutes a considerable handicap because it is an invisible disability and compromises optimal development and personal achievement of a child. The period from birth to 5 years of life is critical for the development of speech and language; therefore, there is need for early identification and assessment of hearing loss and early rehabilitation in infants and children. Cochlear implants are the treatment of choice for patients with severe to profound sensorineural hearing loss. The goal of the present study was to investigate the different hearing impairment etiologies of patients implanted in cochlear implant program. The hospital based interventional study was conducted in the Department of Otorhinolaryngology, SMS Medical College, Jaipur from July 2011 to Dec. 2013. Present study included 60 prelingually deafened patients who attended ENT OPD and underwent cochlear implant. The most common cause of deafness in our study was acquired (56.66%), which predominantly included perinatal risk factors (64.70%), followed by prenatal risk factors (41.17%). The second common cause was hereditary (26.66%), followed by unknown (16.66%). Infection and ototoxic drug history were the most common risk factors in prenatal and postnatal group. The most common perinatal cause was low birth weight and prematurity.

Wayne M. Garrison, Joseph H. Bochner
Health (Health) , 2017, DOI: 10.4236/health.2017.94051
Objective: Less than 15% of adults in the USA over age 70 receive hearing screening; less than 20% of adults with hearing loss receive any form of treatment. Reasons vary, but affordability and accessibility are major barriers to intervention and treatment. This study provides data supporting a new adult hearing screening measure (NSRT) that is self-administered, easy to use and focused on difficulties experienced in everyday speech communication. Methods: The NSRT test materials are sentence-length utterances containing phonetic contrasts. The test requires respondents to determine whether sentences printed on a computer monitor are the same/different from sentences delivered as auditory stimuli through the computer sound card. The test is administered in quiet and +5 dB SNR background noise. Study participants were 120 adults aged 18 - 88 years. Results: Data obtained from the NSRT testing experience are used to construct a pseudo audiogram. When the predicted hearing thresholds were compared with conventional, clinical puretone measures, the sensitivity and specificity of the NSRT screening measure were 95% and 87%, respectively; diagnostic accuracy was 91%. Conclusions: The NSRT can identify individuals with hearing loss through a simple screening process grounded in standards set by the American Speech-Language-Hearing Association. The NSRT is suitable for administration in clinical and nonclinical settings.

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2018, DOI: 10.4236/ijohns.2018.76036
Abstract: Objective: Determine the etiologies and their impacts of hearing loss at the patients’ worn hearing aid in the international center of hearing correction in Abidjan (ICHC). Material and Method: The study is of transverse and analytical type realized in the ICHC from July 1999 to June 2010. It concerned the files of patients’ worn hearing aid in the center. The patients worn initially in another center but followed in the ICHC were excluded. Data were collected from medical files of patients and concerned etiologies, age, type, degree of hearing loss as well as the prosthetic gains and the satisfaction. Results: Fifteen etiologies were listed with in first three rows the meningitis (17.9%) the presbyacusis (17.5%) and chronic otitis media (12.1%). The degrees of hearing loss in the seven etiologies most frequent were severe and profound in 87.6% of cases to the right and 82.8% to the left. The prosthetic pure tonal gain was significant in case of sound trauma and sudden hearing loss. The prosthetic speech reception threshold gain was only significant in case of presbyacusis and sudden hearing loss. The satisfaction of hearing aids was significant in case of presbyacusis, sudden hearing loss and the sound trauma. Conclusion: The main clauses etiologies were the meningitis and the presbyacusis. The tonal and speech prosthetic gain were significant in case of sudden hearing loss.

Open Journal of Clinical Diagnostics (OJCD) , 2013, DOI: 10.4236/ojcd.2013.33014
Abstract: Alstrom Syndrome is an autosomal recessive genetic disorder affecting multiple systems. The characteristic features of this syndrome are obesity, type 2 diabetes mellitus, rod-cone dystrophy, hearing loss. Developmental delay, nistagmus, dilated cardiomyopathy, hypertension, recurrent pulmonary infections, short stature, hepatic and renal failure endocrine abnormalities are other clinical features of this syndrome. Here we report on a case with Alstrom Syndrome at the age of thirteen. He was referred to medical genetics clinic from endocrinology where he has been watched because of obesity, type 2 diaibetes mellitus and hypogonadism. His parents were first degree relatives. He was also 95% blind and had hearing loss. When we looked up these findings with a clinical diagnosis we thought about Alstrom Syndrome. It is a rare disease and difficult to make differential diagnosis with other similar syndromes, therefore this case will be a good example of Alstrom Syndrome for the literature.

Brazilian Journal of Otorhinolaryngology , 2010, DOI: 10.1590/S1808-86942010000400015
Abstract: treatment in sudden sensorineural hearing loss is a contentious issue, today, oral steroids are the most common choice and considered the best treatment option, but the use of intratympanic steroids has become an attractive alternative, especially in cases when systemic therapy fails, or to avoid the side effects of the systemic use of steroids. aim: to describe the results of intratympanic methylprednisolone in idiopathic sudden sensorineural hearing loss after failure of oral prednisolone. methods: in a prospective study fourteen patients with idiopathic sudden sensorineural hearing loss were treated with intratympanic methylprednisolone after failing in the treatment with systemic steroids. pretreatment and post-treatment audiometric evaluations including pure tone average (pta) and speech reception thresholds (srt) were analyzed. results: ten from 14 patients treated with intra-tympanic methylprednisolone presented with hearing recovery > 20 db in pta or 20% in srt. conclusion: three intratympanic injections of methylprednisolone improved pure-tone average or speech discrimination scores for a subset of sudden hearing loss subjects that failed to benefit from oral steroids.

Samelli, Alessandra Giannella;Andrade, Camila Quintiliano de;Pereira, Marília Barbieri;Matas, Carla Gentile;
International Archives of Otorhinolaryngology , 2013, DOI: 10.7162/S1809-97772013000200003
Abstract: introduction: few population-based studies have quantified hearing levels in brazil; additional studies on this subject are needed. purpose: the purpose of this study was to characterize hearing complaints and the audiological profile of the population served by the clinical audiology service of an academic health center in the western region of s?o paulo, brazil, between 2003 and 2008. an additional aim was to check whether there is a positive association between the signs/symptoms and type of hearing loss. methods: this was a retrospective study of the records of 2,145 patients. the health history, tonal and vocal audiometry, and imitanciometry findings were analyzed. results: the mean age of the patients was 20.6 years. the majority of the subjects had normal hearing thresholds, and the prevalence of hearing loss was approximately 35%. as the patient's age increased, the frequency of conductive hearing loss decreased and that of sensorineural hearing loss increased. there was a tendency toward hearing loss worsening with age. conclusion: hearing complaints can predict the type of hearing loss; therefore, they should always be valued because they can be used as a form of screening and thus help to determine the diagnostic hypothesis. this could help to reduce the gap between the patient's perception of the complaints and the audiological assessment and thus improve the prognosis.

S. G. R. Prakash, Ravichandran Aparna, S. B. Rathna Kumar, Tamsekar Madhav, Kaki Ashritha, Kande Navyatha
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2013, DOI: 10.4236/ijohns.2013.22017
Background: Individuals fitted with hearing aids complain of the unnatural sound quality of their voice, other internally generated sounds such as chewing and swallowing sounds “hollow”, “muffled” sounds. Receiver-In-Canal hearing aids are favored due to small size, discrete appearance and ability to minimize occlusion. Aim: To compare the performance of Receiver-In-Canal (RIC) to traditional ear tip (ET), ear moulds (EM) fittings using Functional gain measures. Method: Ten subjects with flat moderately severe sensori neural hearing loss participated in the study. Subjective unaided and aided measures for digital BTE hearing aids with ear tip, ear mould or Receiver-In-Canal for pure tones of 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz were obtained. Results and Discussion: Higher scores were obtained with Receiver-In-Canal fitting on Functional gain measures. No significant difference between all the three conditions was obtained at low frequencies especially at 500 Hz, as Receiver-In-Canal hearing aids attenuate low frequency sounds automatically when the ear is left open (up to 30 dB less amplification at 500 Hz) especially for hearing in noisy situations. Conclusion: The results suggest that Receiver-In-Canal fittings are an effective means of overcoming the major barriers to the acceptance of amplification and further suggest the clinical importance of subjective measures in measuring aided benefit of open-fit devices in the rehabilitation of person’s with moderately severe to severe SN hearing loss.
