The purpose of this study was to determine the etiology of bilateral sensorineural hearing disorders in children and to evaluate the performed hearing tests by comparison of the results of the objective and subjective tests. The medical history and the hearing tests (behavioral observation audiometry, acoustic evoked potentials and pure tone audiometry) of 106 bilaterally hearing impaired children were analyzed in a retrospective follow-up study. The total group included 52 males and 54 females. The ages at first diagnosis ranged from 4 months to 11 years with a mean age of 42 months and a median of 33 months. The degree of hearing loss for the better hearing ear was mild in one child, moderate in 28 children, severe in 29 children, profound in 32 children and total in 16 children. The delay between the first examination and diagnosis ranged from 0 to 597 days with a mean of 83 days and a median of 28 days. In 47 children (44%) no cause of hearing impairment could be determined. Nin...
Risk factors associated with the diagnosis of Sensorineural Hearing Loss in children
Archives of Otolaryngology and Rhinology, 2018
The hearing loss is the most frequent sensory alteration of the human being, with numerous medical, social, emotional and cultural implications. It is a multicausal pathology and is related to many risk factors. Identify the risk factors for the appearance of hearing loss in the child. Method: A sample of 81 children under 3 years of age with severe to profound sensorineural hearing loss was taken, in which the variables studied were the risk factors for hearing loss defi ned by the Joint Committee on Infant Hearing. Results: Values of the risk factors were found, with the following percentages: hypoxia (55.41%), gestational age less than 30 weeks (27%), weight less than 1500 grams (17.57%), ototoxic drugs (17.57%), jaundice with exsanguineous-transfusion (10.81%), meningitis (9.46%), jaundice treated with phototherapy (9.46%) and TORCH (6.76%). It was found that patients with hearing loss can present one to four risk factors, while in relation to sex again; the hypoxia risk factor has the highest percentage (male 31.59% and female 37.5%). Conclusions: It is clear that the patients analyzed have one or several risk factors related to hearing loss. In our case, hypoxia was the factor that most occurred. Therefore, without the realization of a hearing screening for early detection of deafness, the average age of diagnosis is around three years, when parents or educators begin to detect the fi rst manifestations.
Clinical Study on 136 Children with Sudden Sensorineural Hearing Loss
Chinese Medical Journal, 2016
Sudden sensorineural hearing loss (SSNHL) is defined as a hearing loss with a rapid onset in <3 days, and the level of the hearing loss is more than 30 dB in at least three contiguous frequencies. [1] In the United States, the incidence of SSNHL has been reported to be 27 per 100,000 per year. [2] Some case studies have shown that SSNHL typically occurs between 46 and 49 years of age. [3] Studies of SSNHL in children (CSSNHL) are very rare. It has been reported that 6.6% of patients with SSNHL were under 18 years of age, [4] 3.5% under 14 years, [5] and only 1.2% under 9 years. [6] The pathology of SSNHL remains unclear. However, a series of factors, including viral infections, microcirculatory disorders, autoimmune disorders, and labyrinthine
Sensorineural hearing loss in children
The Lancet, 2005
Sensorineural hearing loss (SNHL) is a multifaceted condition with profound medical, social, and cultural ramifications. Although various terms are used to refer to people with SNHL, that most commonly used by the lay public is deaf (with a lower case "d"). Deafness (with an uppercase "D") defines a cultural group of people united by distinct traditions and strengths arising from the use of sign language as a communication form. Most people who communicate primarily by sign language have congenital SNHL, and many are the offspring of Deaf parents. People who acquire SNHL in later childhood or adulthood generally continue to use oral communication, and few see themselves as members of the Deaf community. Doctors, teachers, audiologists, and other professionals often use the term "hearing impaired" to describe people with any degree of SNHL. Although intended to be neutral, this term arouses powerful emotions for many people, especially those in the Deaf community who reject the notion of SNHL as an impairment. Since no term is completely encapsulating, in this Seminar we use SNHL to refer to people who by audiometric testing have any degree of permanent SNHL. We focus on SNHL in children and explore advances in diagnosis, classification, epidemiology, pathogenesis, management, treatment, and prevention.
Risk Factors for Sensorineural Hearing Loss in Children
Acta Otorrinolaringologica (english Edition), 2012
In the last decade, tremendous progress has been made very rapidly in the development of Early Hearing Detection and Intervention (EHDI) systems as a major public health initiative. The percentage of infants screened annually in Spain has increased significantly since the EHDI systems have expanded to all autonomic regions. Historically, high risk indicators have been used for the identification of infants who should receive audiological evaluation but who live in geographic locations where universal hearing screening is not yet available, to help identify infants who pass neonatal screening but are at risk of developing delayed-onset hearing loss and to identify infants who may have passed neonatal screening but have mild forms of permanent hearing loss. In this review, the standard risk factors for hearing loss are analysed and the risk factors known to be associated with late onset or progressive hearing loss are identified. The recommendation for infants with a risk factor that may be considered as low risk is to perform at least one audiology assessment in 24-30 months. In contrast, for an infant with risk factors known to be associated with late onset or progressive hearing loss (such as cytomegalovirus infection or family history), early and more frequent assessment is appropriate. All infants should have an objective standardised screening of global development with a validated assessment tool at 9, 18 and 24-30 months of age or at any time if the health care professional or the family is concerned.
Epidemiologic patterns in childhood hearing loss: a review
International Journal of Pediatric Otorhinolaryngology, 1989
In an attempt to clarify international epidemiologic trends, a review of the published literature pertaining to childhood hearing loss is presented. Inconsistencies of methodology and classification, which complicate the interpretation of data and make difficult the quantification of the influence of genuine population differences, are discussed. Selective review of the literature allows certain crude statements to be made regarding childhood hearing loss. In developed countries, serous otitis media is the most common cause of hearing loss in children, affecting up to two thirds of preschool children. In addition, l.O-2.0/1000 children have bilateral SNHL of at least 50 dB. In underdeveloped countries, suppurative middle ear disease is common and is still frequently associated with either an intratemporal or intracranial complication. SNHL appears to occur almost twice as often as in developed countries, with a greater proportion being of infectious etiology. In specific populations, the Inuits, Amerindians and Aboriginals, acute and chronic suppurative otitis media are almost endemic, yet both cholesteatoma and serous otitis media are uncommon. * Some facets of this paper were presented at the November 1987 meeting of the International Association of Physicans in Audiology.
Demography and etiology of congenital sensorineural hearing loss in children
International Journal of Otorhinolaryngology and Head and Neck Surgery, 2018
Background: The prevalence of sensorineural hearing loss (SNHL) is 2-3 per 1000 live births in India, and out of 1000 babies, 1 is having profound degree of hearing loss at birth or in the pre-lingual age group. Hearing loss is categorized as syndromic or non-syndromic hearing loss. The present study was done to identify and diagnose children with SNHL and study the etiological profile, so that all necessary timely precautions may be taken as SNHL in pediatric age group affects not only development of speech and language, but also emotional, social and behavioural development.Methods: A cross-sectional observational study was carried out in Department of ENT of a tertiary care centre, in 50 children with congenital SNHL. Data on epidemiological and etiological factors were collected. All cases were analyzed for detailed history and underwent clinical and audiological assessment. Results: Majority of cases presented between 2 and 4 years of age, however age of detection of congenita...
Pathogenesis and Etiology of Hearing Loss in Children
Hearing loss in infancy leads to preventable speech, language, and cognitive developmental delay [1, 2]. Sensorineural hearing loss (SNHL) is caused by damages, problems, or issues related to the inner ear such as the cochlea with or without the auditory nerve; cranial nerve VIII, involvement. There are three anatomic areas which include the outer ear: composed of the auricle and external auditory canal and the middle ear: which includes the tympanic membrane, ossicles, and the middle ear space, the inner ear: composed of the cochlea, semi-circular canals, and internal auditory canals. The unique anatomical shape of the auricle catches the incoming sound waves to send them down the external auditory canal. Hearing risk assessment should be part of all health visits while regular hearing screening checks are done for all children from 4 to 21 years [1, 2]. Assessment of hearing loss includes history, physical examination and specific hearing assessment tests.
Non infectious risk factors in pediatric sensorineural hearing loss
2017
Pediatric sensorineural hearing loss can cause delay in speech and daily social communication. The causative factors are infectious or non infecious. The role of infectious risk factors in pediatric sensorineral hearing loss has been proven. However, the role of non infectious factors has not been reported, yet. The aim of the study was to evaluate the role of non infectious factors in pediatric sensorineural hearing loss (SNHL). This was a case control study using data collected from outpatients and medical records in Dr. Sardjito General Hospital, Yogyakarta from June to December 2015. The inclusion criteria of case group were children with SNHL and aged 0 – 5 years old, whereas the inclusion criteria of control group was children with normal hearing and aged 0-5 years old. The exclusion criteria were children with history of infectious risk factors and head trauma. Hearing status were determined by Otoacoustic Emission Testing (OAE) and Brainstem Evoked Response Auditory (BERA), ...
