Full Text Available Introduction The paper presents historical data on development of audiology as a medical specialty. It gives the chronological overview of the most significant discoveries which have contributed to the progress and constant development of the science of hearing. The insights and discoveries encompass the ancient, medieval and contemporary medical science. The term "audiology" and first associations of audiologists The paper reviews the origin of the term “audiology” and the time of its occurrence. The First World Congress of Audiologists was held in 1948, and the Conference of Audiologists and Phoniatrists of Yugoslavia was established in 1974. Historical overview The ancient scientists and philosophers mentioned in the paper are as follows: Democritus, Hippocrates, Empedocles, Plato, Aristotle, and Galenus. Discoveries of Vesalius, Fallopio, Eustachio, Duverney, Schelhammer, Catugno and Helmholtz marked their epochs and made a great contribution to the development of the entire medical science, including audiology. A significant contribution to audiology was made by Schwartz in 1920 and Fletcher in 1926, constructors of audiometers. Fowler, Weigel and Fletcher promoted an audiogram in 1922. Wever and Bray first introduced the cochlear microphonic potentials. The first modern audiometer with a flat zero line for all pitches was constructed in 1937. In 1947, Békésy constructed the automatic audiometer, and the theory of mobile waves was introduced in 1928. Fletcher and Steinberg promoted speech audiometries in 1929. Mendel and Goldstein described medium latency responses in 1969. The first hearing aids worn within the ear appeared in the same year. William House pioneered the cochlear implantation in adults in 1969, and the program of infant cochlear implants. Jewett described the evoked auditory potentials in 1970. James Jerger classified tympanometric curves into three tympanogram types (A, B, C. Portmann and Arran introduced

Full Text Available Introduction Vestibular schwannoma (acoustic neuroma is a rare, but important cause of sensorineural hearing loss. Patients with asymmetric hearing loss, or unilateral tinnitus should be evaluated expeditiously, to prevent further neurological damage. Audiologic diagnostics Audiologic diagnostics represents the basic diagnosis for early detection of vestibular schwannoma. Patients with vestibular schwannomas may present with a variety of clinical features, including retrocochlear pattern of sensorineural hearing loss. Supraliminary audiometry, tympano- metry, stapedius reflex and otoacoustic emissions as well as vestibular response to caloric testing are methods for selection of patients with suspicion of this tumor. Conclusion The golden standard for audiologic diagnostics of vestibular schwannoma is BAEP (Brainstem Auditory Evoked Potentials. Patients with pathological findings of BAEP should undergo MRI of the posterior fossa. Gadolinium-enhanced magnetic resonance imaging is the best and final tool for making a diagnosis of vestibular schwannoma.
Full Text Available Introduction: The agricultural airplane pilot are daily exposed to intense noises, being susceptible to the noise-induced hearing loss (NIHL and its auditory and extra auditory effects. Objective: To analyze the audiological profile of this population, verifying the work's influence on its hearing. Method: It was realized a retrospective, individual, observational, and cross-sectional study through the data obtained by means of a questionnaire and audiometric thresholds of 41 agricultural pilots. To the statistical analysis were utilized the chi-square, Spearman, and Wilcoxon tests with significance level of 5%. Results: It was verified that 95,1% of the pilots use PPE ( personal protective equipment during flight and 58,5% have contact with pesticides. More than half of individuals referred to feel auditory and extra auditory symptoms, being the buzz the more frequent (29,1%. It has the occurrence of 29,3% of NIHL suggestive hearing loss and 68,3% of normality, taking this presence of unilateral notch in 24,4% and bilateral notch in 31,7%. It was found correlation statistically significant in the associations between time of service and the average of the acute frequencies in the right ear (p=0038, and in the left ear (p=0,010. It has a statistical tendency in the association between audiometric configuration and contact with pesticides (p=0,088. Conclusion: The hearing loss prevalence in this study was showed high. More than half of the sample has normal audiometric thresholds with notch configuration. Such data lead to the conclusion that the agricultural pilots, even with PPE use, they still suffer with the damages caused by noise, needing best proposals of hearing loss prevention.

The present report provides an overview of terminology studies in audiology including topics and study characteristics, as well as categorizing the main issues. The goals are to improve the understanding of the current issues for terminology in audiology and to provide some basic information that will be useful to develop an international standard. Search procedures were completed over two phases. Phase 1 included a systematic electronic searches using MEDLINE (PubMed), Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, and International Organization for Standardization with keywords related to terminology of audiology. The studies were initially identified according to the titles of 2921 publications following careful abstract examination. Of these, whole texts of 16 publications were retrieved. Five papers met the inclusion criteria were further investigated. In phase 2, a manual search was conducted to collect additional publications with keywords related to terminology project in audiology. A total of 16 papers were found. The essential terminology issues classified included 'appropriateness,' 'classification/framework,' 'inconsistency of terminology,' 'multilingual and international aspects,' and 'service quality/delivery including communication and accessibility.' This was indicative of the paucity of terminology research in audiology, despite recurring terminology issues. Establishment of standardized terminology in audiology may minimize current challenging terminology issues by improving appropriateness and consistency of terminology as well as communication among relevant stakeholders at national and international levels.

Full Text Available Objectives: The aim of our study is to find out whether early identification and intervention prevents severe linguistic and communication delays, minimizing the need for more elaborate rehabilitation during the school years. Design and Study Sample: A Cross-sectional study was carried out on one hundred and eleven children with documented deaf-mutism presenting at the Department of Oto-Rhino-Laryngology in two different geographical regions of India. Detailed history, clinical and audiological assessment along with assessment of the language and communication skills according to American Speech Language Hearing Association (ASHA guidelines was done. Results: The children were predominantly male, of low socio-economic background, presented for rehabilitation, mostly after the age of six years. They commonly had more than 70dBHL (decibel hearing level hearing threshold. The study found that the children who presented early for diagnosis and hearing aid usage had better response to rehabilitation. Conclusion: It is important that hearing loss be detected at an early age and amplification should be introduced as early as possible once there has been a diagnosis of a hearing loss. So that early intervention can have an impact on speech and language development. Without concurrent follow-up program, identification of hearing loss early in children is meaningless.
Given the growth in the aging population, low hearing uptake rates and the emerging science indicating that age-related hearing loss has long term consequences to health and wellness, an interventional audiology strategy is needed. This paper will define interventional audiology and offer guidance on bringing an interventional audiology to life in clinical practice.

There is a large demand for the provision of hearing aids. However, there are lengthy delays involved between referral and fitment of National Health Service (NHS) hearing aids. This report shows that a general practice based audiology clinic can lead to an increase in the number of patients referred and fitted with a hearing aid. The introduction of the clinic also led to reduced waiting times for patients to be fitted with hearing aids.

Full Text Available Introduction: Mucopolysaccharidosis are characterized by the deficit of lysosomal enzymes corrupting the glycosaminoglycans. Accumulating these metabolites causes several alterations, such as otologic alterations. Objective: To evaluate a number of patients with mucopolysaccharidosis at Pequeno Principe Hospital, emphasizing their audiologic alterations and establish a permanent evaluation protocol for these patients. Method: A backward-looking study of audiologic evaluation by using records of 18 patients diagnosed with mucopolysaccharidosis and attended at Pequeno Principe Hospital between January 2005 and November 2010. Results: 7 records were selected, out of which only one did not have a hearing loss, and most of them presented conductive or mixed hearing loss, and only one had an exclusively sensorineural loss. Six of these patients had also been submitted to at least one otorhinolaryngological procedure. Conclusion: Mucopolysaccharidosis patients require a permanent care and a multidisciplinary follow-up. The pediatric otorhinolaryngologist plays an important role when performing the otologic and audiologic evaluation and managing the airways, since almost all the patients evaluated presented some kind of hearing loss and an indication of otorhinolaryngologic procedure. The pattern determined in our service was at least an initial consultation when there is a suspicion and/or diagnosis of MPS and sequential consultations that were at least twice a year or more frequent, if necessary.

In this paper, we trace the history of those forms of rationality that comprise the present situation in hearing clinics. The paper takes as a starting point the 1950s when audiology became a public service. The formation of the field of audiology is framed according to Bourdieu's conception of...... fields. This approach allows for constructing results in a historical account where we focus on scientific developments emerging as alliances and conflicts between claims of authority and their subsequent impact on rehabilitative audiology and the different conceptualisations of hearing impairment. How...... the audiological field is structured and how services are provided are matters of 'accumulated history'. Our findings illustrate how the myth of present audiological scientific reason is not merely logical and rational but also complex and contradictory....

The level of improvement in the audiological results of Baha(®) users mainly depends on the patient's preoperative hearing thresholds and the type of Baha sound processor used. This investigation shows correlations between the preoperative hearing threshold and postoperative aided thresholds and audiological results in speech understanding in quiet of 84 Baha users with unilateral conductive hearing loss, bilateral conductive hearing loss and bilateral mixed hearing loss. Secondly, speech understanding in noise of 26 Baha users with different Baha sound processors (Compact, Divino, and BP100) is investigated. Linear regression between aided sound field thresholds and bone conduction (BC) thresholds of the better ear shows highest correlation coefficients and the steepest slope. Differences between better BC thresholds and aided sound field thresholds are smallest for mid-frequencies (1 and 2 kHz) and become larger at 0.5 and 4 kHz. For Baha users, the gain in speech recognition in quiet can be expected to lie in the order of magnitude of the gain in their hearing threshold. Compared to its predecessor sound processors Baha(®) Compact and Baha(®) Divino, Baha(®) BP100 improves speech understanding in noise significantly by +0.9 to +4.6 dB signal-to-noise ratio, depending on the setting and the use of directional microphone. For Baha users with unilateral and bilateral conductive hearing loss and bilateral mixed hearing loss, audiological results in aided sound field thresholds can be estimated with the better BC hearing threshold. The benefit in speech understanding in quiet can be expected to be similar to the gain in their sound field hearing threshold. The most recent technology of Baha sound processor improves speech understanding in noise by an order of magnitude that is well perceived by users and which can be very useful in everyday life.

The hearing aid delivery landscape has dramatically changed over the past several years, with a commercial payer, the Internet, and big box stores dispensing hearing aids directly to patients. The audiology community needs to modify the bundled billing model. This session will describe how to optimize the services you provide to current and new patients and change the hearing aid delivery and hearing aid pricing model to remain competitive with these new market trends. This activity will educate participants on itemized billing, sometimes referred to as unbundling, its pros and cons, and how it could aid audiologists in differentiating themselves in the hearing aid delivery landscape.

Full Text Available INTRODUCTION Currently available evidence reveals comparatively few studies of psychological effects of hearing impairments, in spite of the fact that clinicians have for a long time been aware of a connection between the acquired hearing impairment and mental disorders. They are focused on the investigation of dysfunction in general. Thus, three domains of the auditory imbalance may be distinguished: disorder, disability and handicap. 'Handicap', according to the definition of the World Health Organization, is a hindrance in an individual that results from an impairment or disability and represents psychological response of the individual to the impairment. OBJECTIVE Validation of acquired hearing impairment as a risk factor of psychical disorders as well as an analysis of relation of some demographic factors (sex, age, education and audiological factors (degree and duration of the impairment with the frequency of hearing handicap. METHOD MMPI-201 has been applied in 60 subjects affected with otosclerosis, potential candidates for stapedectomy, before and after the surgery. RESULTS Individuals with acquired hearing impairment manifest more frequent disorders of psychical functioning in comparison with general population, while demographic and audiometric parameters did not correlate with acquired hearing handicap. CONCLUSION It may be assumed that the very recognition of demographic and audio-logical factors can not help much in the understanding of the psychological stress associated with hearing impairment.

audiologist, however, is trained to deal with the intersection of technical or physiological evaluations. The issue, therefore, is how the client comes to mention cognitive abilities, despite the audiologists agenda. Using conversation analysis as a methodology, video recorded audiology consultations are...... examined in order to show how the client’s mentioning of his cognitive abilities appear in a specific sequential environment: Right after the audiologist has expressed or implied reservations with regard to whether the client’s report on hearing experiences can be accurate. The remarks seem to appeal to a...... establishing such a report, clients at times mention issues regarding their cognitive abilitities, rather than only reporting physiological or technical issues. These mentionings can be direct (as in ‘do you think I am imagining this?’) or reported (as in ‘in such situations, I appear as an idiot’). The...

Computer methods, based on the theory and application of signal processing, combined with numerical methods for simulating mathematical processes, facilitate greater objectivity in most aspects of speech intelligibility testing, including specification of the stimuli, control of the tests, evaluation of the responses, corrective feedback, and automatic interpretation. This paper discusses several basic issues in digital signal processing, and also describes the application of computer-aided procedures for recording and delivery of speech materials for audiologic research. Examples of the use of computer procedures for manipulation of digitized stimuli demonstrate the increased efficiency and versatility of these procedures compared to more conventional tape recording methods. In addition, the use of digitized recordings allows more reliable specification of speech levels than conventional calibration methods involving observations of signal peaks on a VU-meter.

Full Text Available OBJECTIVE: To correlate the audio-logical profile in diabetes mellitus with inflammatory markers (TNFα, IL-6, CRP, and FREE RAICALS. MATERIALS AND METHODS: A two year prospective study of Audio-logical profile and its correlation with inflammatory markers was done in 35 diabetic patients attending Diabetic OPD and ENT OPD at RMMCH between 2012- 2014.Patients with diabetes mellitus on oral hypoglycaemic agents or insulin therapy was subjected to Pure Tone Audiometry using Arphi Audiometer-Model 700MK4 and Inflammatory marker study. STATISTICS AND ANALYSIS: P-value was found out by ANOVA method to find out the significance of auditory thresholds between various categories of parameters. RESULTS: Patients with Diabetes Mellitus were more commonly affected by Sensori-neural Hearing loss in the age group between 41- 49 years accounting for 77.14%. Females were more affected in our study in the ratio3.3:1. Hearing loss was bilaterally symmetrical and of sensori-neural type affecting mainly the higher frequencies. In 77.1% of our patients the duration of diabetes mellitus was less than 5years, however there was no correlation between the duration of diabetes mellitus and hearing loss. Control in the severity of diabetes mellitus lead to improvement in hearing thresholds, which was statistically significant at higher frequencies. CONCLUSION: There was a positive correlation between increased level of inflammatory markers-TNF α, IL-6, CRP, free radicals and hearing loss in diabetes mellitus. However the inclusion of elevated markers as a prognostic index to assess the degree of deafness and its relation to microangiopathy needs further studies and its role in prevention of deafness in diabetes mellitus needs further evaluation.

Full Text Available Daily activities, interpersonal relationship, employment, and general well being; among such skills, communication skills are essential to a successful life for all individuals. Such skills affect education, adequate hearing acuity is of paramount importance and acts as a prerequisite in the overall personality development of an individual. Hearing impairment at any age has serious effects on the day to day life of an individual and he/she feels handicapped socially, emotionally, and scholastically. A child stuck with this malady is a back bencher in the class, excommunicative, and absent-minded. This study was conducted in order to find out various causes of hearing impairment in children and to study role of various audiological and radiological tests in finding the cause of impaired hearing in children. Aims and Objectives: To assess the possible etiological causes of hearing impairment in children. Study role of various audiological tests in finding the cause of impaired hearing in children. Study Design: Prospective study. Materials and Methods: This study was conducted in the Department of ENT and HNS of government medical college Srinagar. A total of 150 children of age range 0-14 years visited our ENT Department with complaints of impaired hearing, but only 70 children who met the inclusion criteria of impaired hearing and defective/delayed speech were selected for this study. Results of initial evaluation by means of comprehensive clinical history and followed by proper thorough systemic physical examination from head to toe was performed. These hearing impaired children were subjected to various subjective and objective tests; pure tone audiometry and behavioral observation audiometry were performed for subjective tests and impedance audiometry, Oto-acoustic emissions (OAE, and brainstem evoked response audiometry (BERA were performed for objective tests.

The objective of this study was to examine behaviors and attitudes of Brazilian teenagers towards noise, and determine their audiological characteristics. Participants were 245 young persons (14 to 18 years old) who attended private school. Behaviors and attitudes were measured using the validated Portuguese version of the Youth Attitude to Noise Scale (YANS). Pure-tone audiometry was used to evaluate the hearing of a sub-sample of 24 participants. Music played through personal media players was the most common exposure reported. A substantial percentage of participants reported temporary tinnitus (69%) after attending discos, music concerts, and listening to music through headphones. Tinnitus complaints were more frequent among females (41%) than males (27%). Four participants (1.6%) reported use of a hearing protector. Among a subsample of 24 participants, two (8%) young women had bilateral audiometric notches. YANS scores in the present study were slightly lower than those obtained in Sweden and the US, indicating a more negative attitude towards noise. Gender, age, country, and/or region are variables that will influence exposure to noise or music and possibly hearing outcomes. PMID:19863355
Full Text Available Objective: Tinnitus is widespread amongst clients attending hearing clinics and has been associated with a range of physical and emotional disorders. This study was undertaken with the assumption that tinnitus has a negative impact on psychological well-being as well as on mental concentration of the person. Materials and Methods: Three groups were selected, comprising 10 participants each. Two groups consisted of subjects with tinnitus complaints. The first group had no hearing loss (Tinnitus group (TIG, the second group had mild hearing loss (PTA >25, <40 dBHL (Tinnitus group with hearing impairment (TWHIG, and the third group had no tinnitus or hearing loss (Normal control group (NCG. After an audiological assessment, the following questionnaires were administered: 1 nature of tinnitus questionnaire, 2 tinnitus reaction questionnaire, 3 the symptom checklist (SCL-90-R, and 4 cognitive failure questionnaire (CFQ. Out of these, four were administered to all tinnitus groups while only the last two were administered on NCG. The results of these tests were compared using a t- test. Results: Participants with tinnitus reported significantly more psychological distress symptoms and everyday cognitive failures than the control group. Conclusion: Our assumption about the potential negative impact of tinnitus on psychological well-being as well as on mental concentration is supported by our study results. Implication: The present study indicates that there is a greater need for providing counseling as well as psychological intervention to reduce stress and assistance in coping with the cognitive failures for persons with tinnitus.

Full Text Available Introduction: At the initial consultation, the speech-language pathologist and audiologist may consider possible diagnostic hypotheses based on the child's history and the parents' complaint. Aim: To investigate the association of hearing complaints with the findings obtained in the conventional audiologic assessment in children with cleft lip and palate. Retrospective study. Methods: We analyzed medical charts of 1000 patients with cleft lip and palate who underwent surgical repair between 1988 and 1995 at a mean age of 6 years 8 months. We excluded charts with records of inconsistent audiological responses and charts with missing data for any of the audiologic evaluations considered. Thus, the sample consisted of 393 records. Results: Two hundred thirty-nine patients presented hearing loss in one or both ears, but only 3.8% reported hearing complaints. The most frequent were otorrhea followed by otalgia. There was no statistical significance between the complaint and gender (p = 0.26 nor between the complaint and hearing loss (p = 0.83. Conclusion: This study showed no association between the hearing complaint and the conventional audiologic assessment.

Full Text Available Introduction: The military police are a population exposed to noise impact due to training with firearms. Objective: To investigate the audiological profile of the military police in São Paulo state, and to correlate the age and duration of exposure and audiological findings. Method: In this study of case series, cross-sectional audiological evaluation was performed in 200 police officers being 169 (84.5% were male and 31 (15.5% females, aged between 25 and 45 years (mean 38.83 ± 5.05, average service time of 16.80 ± 6.27 years. Results: The main complains were: tinnitus (n=52/26%, hearing loss (n=36/18%, ear fullness (n=24/12% and autophonia (n=24/12%. Impedance were found in 100% of type A curves (JERGER, 1970, and recruitment was present in 20 (10% cases. According to the results of audiometry, the data showed that 54 (27% right ears and 56 (28% left ears had hearing loss. The degree of loss with higher prevalence was 1 and 2 (MERLUZZI et al., 1979, 85 (42.5% cases. There was significant correlation between age and exposure time with the worsening of audiometric thresholds in both ears. Conclusion: From the audiological data analysis was possible that the military police are a population that presents a risk to develop hearing loss. Thus, we see the need for implementation of hearing conservation program for the military police.

Full Text Available Background: In future, the South African Department of Health aims to purchase services from accredited private service providers. Successful private audiology practices can assist to address issues of access, equity and quality of health services. It is not sufficient to be an excellent clinician, since audiology practices are businesses that must also be managed effectively.Objective: The objective was to determine the existing and required levels of practice management knowledge as perceived by South African audiologists. Method: An electronic descriptive survey was used to investigate audiology practice management amongst South African audiologists. A total of 147 respondents completed the survey. Results were analysed by calculating descriptive statistics. The Z-proportional test was used to identify significant differences between existing and required levels of practice management knowledge. Results: Significant differences were found between existing and required levels of knowledge regarding all eight practice management tasks, particularly legal and ethical issues and marketing and accounting. There were small differences in the knowledge required for practice management tasks amongst respondents working in public and private settings. Conclusion: Irrespective of their work context, respondents showed that they need significant expansion of practice management knowledge in order to be successful, to compete effectively and to make sense of a complex marketplace.

Permanent hearing loss is a leading global health care burden, with 1 in 10 people affected to a mild or greater degree. A shortage of trained healthcare professionals and associated infrastructure and resource limitations mean that hearing health services are unavailable to the majority of the world population. Utilizing information and communication technology in hearing health care, or tele-audiology, combined with automation offer unique opportunities for improved clinical care, widespread access to services, and more cost-effective and sustainable hearing health care. Tele-audiology demonstrates significant potential in areas such as education and training of hearing health care professionals, paraprofessionals, parents, and adults with hearing disorders; screening for auditory disorders; diagnosis of hearing loss; and intervention services. Global connectivity is rapidly growing with increasingly widespread distribution into underserved communities where audiological services may be facilitated through telehealth models. Although many questions related to aspects such as quality control, licensure, jurisdictional responsibility, certification and reimbursement still need to be addressed; no alternative strategy can currently offer the same potential reach for impacting the global burden of hearing loss in the near and foreseeable future.

Full Text Available Background: To counter the global increase in infection-related deaths, infection control has recently developed into an active area of research. Many diseases can be prevented by infection control. In the confines of the audiology clinic, cross-contamination by micro-organisms associated with opportunistic infections remains a real concern.Objective: The primary aim of the study was to ascertain the methods that audiologists in South Africa use to prevent and control the spread of infections during and after consultation with clients.Method: A survey study was conducted, using a self-administered questionnaire. Fifty currently practising audiologists participated in the study.Results: The majority (84%; n = 42 of respondents acknowledged the importance of hand hygiene for the purpose of infection control, with 76% (n = 38 making use of no-rinse hand sanitisers. Approximately a third of audiologists wear gloves during procedures such as otoscopy and immittance, and while handling hearing aids. Disinfecting audiological equipment seem to be the preferred choice of infection control, with only 60% (n = 30 of respondents sterilising audiological equipment after each individual patient consultation. Less than half of the respondents disinfected touch surfaces and toys in the reception area.Conclusions: Based on the results, further education and training should focus on measures implemented in infection control, awareness of possible risk factors at work settings, and vaccination as an effective means of infection control.
Full Text Available Aim: Children with multiple disabilities have combination of various disabilities. Accurate hearing evaluation is difficult in this population. Audiologists, generally employ a test battery approach, which includes combining findings of parent impression with behavior observation audiometry (BOA as well as auditory brainstem evoked responses (ABR findings. This study was carried out to find if there exists a correlation among various steps in the test battery for children with multiple handicaps as well as to find out, which disability is the most common among this population. Methodology: A total of 103 numbers of children with multiple handicaps were chosen at random who were referred to C U Shah Institute of Audiology and Speech Therapy for audiological assessment. The three steps involved in assessment that is parental impression, BOA and ABR findings were taken into account. The relationship was obtained using data analysis. Results: It was found that among children with multiple handicaps referred for audiological assessment, mental retardation was the most common (32.03%. Furthermore, it was found that there were more contradictory findings between parent impression and ABR (48% when compared with parent impression with BOA (38%. In between BOA and ABR contradictory findings were found in 41% of cases. Conclusion: There are wide contradictions among various steps involved in assessment of children with multiple handicaps. Implication: Audiologist should use a test battery approach to assess hearing ability of this population and audiologists should interpret findings carefully at each level.

Full Text Available Tinnitus is the most prevalent service-connected disability awarded to Veterans. However, clinical protocols for management of tinnitus have been inconsistent across Department of Veterans Affairs (VA medical centers. A study was funded to develop and pilot test a protocol to provide tinnitus services consistently across VA audiology clinics. Drawing on a series of prior VA and external research projects, a clinical model was formulated, supporting materials in multimedia were developed, and a pilot study was conducted. Five hierarchical levels of care were defined and labeled the Progressive Audiologic Tinnitus Management (PATM model. The model facilitates access to medical services for tinnitus and includes detailed protocols for evaluation, education, and counseling of patients. Patients at each level of care have the option to "progress" to the next level of PATM if further services are required. Clinical procedures were defined for each level and materials were produced for audiologists and patients. The PATM model was then piloted with clinical patients at the James A. Haley Veterans’ Hospital (JAHVH in Tampa, Florida. Throughout the pilot study, feedback from patients and clinicians was carefully noted. Training materials for audiologists, incorporation of the protocol into clinic activities, and patient outcomes were evaluated. The model was implemented within the JAHVH Audiology Clinic and to assist Veterans with tinnitus management. The most notable finding was how little tinnitus-specific intervention was required for the majority of patients. This finding supports a clinical model that offers stepped-care ("progressive" levels of care until tinnitus management is achieved by the patient.

Full Text Available Abstract The early identification of pre-lingual deafness is necessary to minimize the consequences of hearing impairment on the future communication skills of a baby. According to the most recent international guidelines the deafness diagnosis must occur before the age of three months and the prosthetic-rehabilitative treatment with a traditional hearing aid should start within the first six months. When a Cochlear implant becomes necessary, the treatment should start between the age of 12 months and 18 months. The only way to diagnose the problem early is the implementation of universal neonatal audiological screening programs. Transient evoked otoacoustic emissions (TEOAE is the most adequate test because it's accurate, economic and of simple execution. Automatic auditory brainstem response (AABR is necessary to identify patients with auditory neuropathy but it is also important to reduce the number of false-positives.The 20-30% of infant hearing impairment is represented by progressive or late-onset hearing loss (HL so it's also necessary to establish an audiological follow up program, especially in infants at risk. From November 2005 all neonates born in the University hospital of Pisa undergo newborn hearing screening. From 2008 the screening program follows the guidelines for the execution of the audiological screening in Tuscany which have been formulated by our group according to the 2007 JCIH Position Statement and adaptated to our regional reality by a multidisciplinary effort. From November 2005 to April 2009 8113 neonates born in the Neonatal Unit of Santa Chiara Hospital (Pisa have undergone newborn hearing screening. 7621 neonates (93.9% without risk factors executed only the TEOAE test. 492 (6.1% neonates had audiological risk factors and thus underwent TEOAE and AABR. 84 patients (1,04% failed both TEOAE and AABR tests. 78 of them underwent further investigations. 44 patients resulted falsepositives (the 0,54% of the screened

Traditional approaches to unbundling hearing aid services often take existing bundled charges and then separate the charges across all potential services associated with dispensing the devices. However, this method results in every patient being charged the same amount even though the complexity of the service varies across patients. We describe a model of charging for hearing aid services that takes into account three elements associated with patient services (i.e., assessing hearing status, audiologic decision making and interpretation, and counseling and treatment options) and two levels of complexity (straightforward and complex). Using this approach, there is negligible long-term financial impact on a practice however patients will perceive a lower overall cost for amplification. Additionally, this approach provides a payment structure more representative of the professional value of each visit.

A profile of audiological and psychological characteristics, obtained before starting tinnitus management training, is presented for 96 subjects with tinnitus. Variability was marked in all measures. A history of headaches, neck or back pain, or balance problems was not related to the ability to cope with tinnitus. The coping strategies used to manage tinnitus were influenced by the beliefs held about tinnitus, but the coping strategies chosen were not necessarily effective. No gender differences were found in coping ability or overall stress levels, although there were gender differences on some psychological measures and stress influences. Subjects who had previously sought assistance differed from those who had not in the complexity of the tinnitus sounds, the level of emotional reaction and the use of coping behaviours. PMID:9056041

Stand audiological tests were administered to a totally deaf multiple-channel cochlear implant patient with a wearable speech-processor in a monitored sound field under the following conditions: a wearable unit activated alone (WA), lipreading with the wearable unit off (LA), and wearable unit activated in combination with lipreading (WL). Thresholds obtained for narrow-band noise signals indicated that the wearable unit allowed the patient to detect a variety of sounds at different frequencies. The results obtained in closed-set word tests and open-set word and sentence tests showed significant improvements in word and sentence scores from LA to WL. In the open-set (C.I.D.) sentence test, the patient scored 22% for LA and 76% for WL. The WL score of 76% correlates with a satisfactory performance in understanding connected speech. The patient also scored 30% correct in a test involving the recognition of environmental sounds. PMID:6895683

Full Text Available Introduction: The noise induced hearing loss (NIHL has been studied for many years and today the specialized literature also studies the synergic action of chemicals. Objective: To research the audiologic findings and DPOAE in workers exposed to occupational noise and plaguecides and to compare them with data obtained in individuals without exposure to these harmful elements. Method: 51 individuals were evaluated (102 ears, divided into three groups. Group I was composed by 17 workers with exposure to noise and plaguecides, all with neurosensorial auditory loss; group II was composed by 17 workers with exposure to noise and plaguecides with audiometric thresholds within normality standards (up to 25 dBNA and group III by 17 healthy individuals without auditory alterations and without exposure to noise and plaguecides, control group. Results: In the audiologic anamnesis, as for groups I and II, we observed that the main auditory complaints presented by the workers were those of recruitment (29.5%, tinnitus (26.5%, allergy (23.5% and arterial hypertension (12%. The findings of the audiometry appointed that the research's individuals did not present with auditory losses in the frequencies of 500 Hz, 1 and 2 kHz, the losses occurred in the frequencies of 3 and 8 kHz. As for the distortion-product otoacoustic emissions (DPOAEs, we observed that the individuals in group III had a major incidence of responses when compared to those of groups I and II. Conclusion: The results analysis allowed us to conclude that the DPOAE test represents an important tool for follow up and prevention of NIHL.

The World Health Organization's International Classification of Functioning, Disability and Health (ICF) is widely used in disability and health sectors as a framework to describe the far-reaching effects of a range of health conditions on individuals. This biopsychosocial framework can be used to describe the experience of an individual in the components of body functions, body structures, and activities and participation, and it considers the influence of contextual factors (environmental and personal) on these components. Application of the ICF in audiology allows the use of a common language between health care professionals in both clinical and research settings. Furthermore, the ICF is promoted as a means of facilitating patient-centered care. In this article, the relevance and application of the ICF to audiology is described, along with clinical examples of its application in the assessment and management of children and adults with hearing loss. Importantly, the skills necessary for clinicians to apply the ICF effectively are discussed. PMID:27489397

Ira Hirsh's contributions to clinical science and research are diverse and significant. In fact, approximately one-third of the 100+ publications that Ira lists in his curriculum vitae (CV) are clinical in nature, dealing with various aspects of audiology, deafness, hearing aids, aural rehabilitation, and speech and language pathology. The majority of these citations, fully one-quarter of his publication list, addresses problems specific to the clinical measurement of hearing and hearing impairment. Undoubtedly, the most influential of these published works appears in his CV under the citation ``The Measurement of Hearing.'' The forward for this publication, his only textbook, was penned in June, 1952 (now precisely half a century past at the time of this session). The aims of this presentation are to (1) provide perspective on the fundamental importance of his virtually timeless text in shaping the fledgling discipline of audiology, and (2) celebrate Ira's many contributions to the profession and practice of audiology. [Preparation for this presentation was supported, in part, by a K24 career development award from NIDCD.

BACKGROUND Cochlear implants (CIs) have been recognized as a safe and effective means for profound hearing loss rehabilitation in children and adults and recently their use has been extended to subjects over 65 years of age. The aim of this paper was to assess indices related to changes in the quality of life (QoL) in elderly CI recipients. MATERIAL AND METHODS A case-control paradigm was used to assess the effects of CIs on the QoL. Forty-two subjects were assigned to the Case group and 15 subjects to the Control group. All 57 subjects were affected by profound hearing loss and had received a CI. Audiological data were collected from both groups at: (i) 1 month pre-implantation [T1]; (ii) 1 day pre- implantation [T2]; (iii) 30 days post-implantation, with CI used in free field [T3]; and (iv) 12 months post-implantation, with CI used in a free field [T4]. The QoL was assessed via a Glasgow Benefit Inventory (GBI) questionnaire, adapted to otolaryngology. To compare subjects across different ages with varying degrees of speech development, a perception parameter was used from the Speech Perception Categories test developed by Geers and Moog. RESULTS Hearing performance was considerably improved after CI. In relation to the hearing performance at time T1, statistically significant threshold gains were observed in both groups in the T3 and T4 observation windows. At time T4, a threshold gain of 70 dB HL in the Case group and a gain of 84 dB HL in the Control group were observed. With speech therapy rehabilitation, a perception level of 6 was reached by 80.0% of patients in the Case group and by 100% of patients in the Control group. In terms of QoL, both groups showed improved post-CI scores. Statistical differences were observed between the 2 groups, with the Control group outperforming the Case group in all but the social section. CONCLUSIONS Despite age-related changes in auditory system and prolonged hearing deprivation, CIs offer audiological and QoL benefits in
Purpose: To find the audiological outcome after LINAC-based fractionated stereotactic irradiation (STI). Materials and methods: Twenty-four patients with vestibular schwannoma treated by fractionated STI between 1991 and 1997 had measurable hearing before STI and were followed audiologically for more than 6 months. The pure tone average (PTA) was measured by averaging the air-conduction threshold for five main frequencies (250-4000 Hz) before and periodically after STI in the 24 patients. Several possible prognostic factors for hearing preservation (defined as a PTA change at the last follow-up of less than 10 dB) were investigated. The median follow-up time was 22 months, ranging from 5 to 69 months. The irradiation schedule was 36 Gy in 20 fractions in 5 weeks to 44 Gy in 22 fractions in 6 weeks followed by 4 Gy/1 fraction boost. Results: The pure tone average before STI was distributed from 7 to 73 dB. Fifty percent of patients showed a change in PTA of less than 10 dB, 79.2% of patients showed a change in PTA of less than 20 dB and 20.8% of patients showed a change in PTA of more than 21 dB at the last follow-up. Only one patient (4%) became deaf. Cases with a sudden loss of hearing were more likely to experience hearing preservation than those with gradual loss of hearing (P<0.05). The mean age was younger in patients whose hearing was preserved (P<0.05). Poor pretreatment PTA appeared to linearly correspond to the changes in PTA (regression coefficient 0.78). The size of the tumor was not related to the change in PTA. No relationship was observed between the maximum or peripheral dose and the PTA change. The real benefit of stereotactic boost after small-field fractionated irradiation was not certain. Conclusion: Fractionated STI produced a hearing preservation rate compatible with meticulously collimated multi-spots single fraction irradiation. Further follow-up is required to confirm the long-term benefits of fractionation. (Copyright (c) 1998 Elsevier

To allow for a systematic variation of linguistic complexity of sentences while acoustically controlling for intelligibility of sentence fragments, a German corpus, Oldenburg linguistically and audiologically controlled sentences (OLACS), was designed, implemented, and evaluated. Sentences were controlled for plausibility with a questionnaire survey. Verification of the speech material was performed in three listening conditions (quiet, stationary, and fluctuating noise) by collecting speech reception thresholds (SRTs) and response latencies as well as individual cognitive measures for 20 young listeners with normal hearing. Consistent differences in response latencies across sentence types verified the effect of linguistic complexity on processing speed. The addition of noise decreased response latencies, giving evidence for different response strategies for measurements in noise. Linguistic complexity had a significant effect on SRT. In fluctuating noise, this effect was more pronounced, indicating that fluctuating noise correlates with stronger cognitive contributions. SRTs in quiet correlated with hearing thresholds, whereas cognitive measures explained up to 40% of the variance in SRTs in noise. In conclusion, OLACS appears to be a suitable tool for assessing the interaction between aspects of speech understanding (including cognitive processing) and speech intelligibility in German.

To evaluate the functionality of the auditory system in patients who underwent radiotherapy and chemotherapy treatment with cisplatin to treat head and neck tumors. Case series with planned data collection. From May 2007 to May 2008 by the Department of Otorhinolaryngology and the Department of Oncology/Radiotherapy at Faculdade de Medicina de Marília. Audiological evaluation (Pure Tone Audiometry (air and bone conduction), Speech Audiometry, Tympanometry, Acoustic Reflex testing and Distortion Product Otoacoustic Emissions) was performed in 17 patients diagnosed with head and neck neoplasia and treated with chemotherapy, using cisplatin, and radiotherapy. 12 left ears (70.5%) and 11 right ears (64.7%) presented bilateral decreased hearing soon after the treatment for the frequency 1 kHz (mild auditory damage) and for the frequency 8 kHz (more significant auditory damage). Patients with head and neck cancer submitted to the conventional radiotherapy treatment, combined with the chemotherapy with cisplatin, presented a high incidence of decreased hearing by the end of treatment. Strong evidence was observed linking auditory alteration to the amount of radiotherapy treatment

Full Text Available Objective: To describe the audiological findings (type, audiometric configuration, degree of hearing loss and its association with gender and age in subjects aged over 60 years, treated at outpatient clinic of specialties of Manaus. Methods: A cross-sectional epidemiological descriptive study conducted with the universe of elderly who underwent audiometry from January to December 2010, with a total of 574 subjects. To classify the type, degree and configuration of hearing loss, we used the criteria adopted by Santos & Russo, Davis & Silverman and Silman & Silverman, respectively. Statistical analysis was performed using measures of central tendency, dispersion and frequency distributions. To check for statistically significant differences, we used the chi-square test, with a significance level of 5% (p ≤ 0.05. Results: The prevalence of 94.4% (n = 542 of hearing loss, sensorineural predominantly (85.5%, n = 491 and mild (60%, n = 188 in females and degree moderate or greater in males (50%, n = 130, downward sloping (54.2%, n = 311 in both sexes. The percentage of normality was low, with 261 (3.4% for men and 313 (7.3% for women. Conclusion: The prevalence of hearing loss increased with age, being equal to 100% in individuals 80 years or older, and men have the worst hearing thresholds. There is need for greater awareness about hearing loss in the elderly, needing additional population-based and multicentric studies in order to support public policies.

The bone-anchored hearing aid (BAHA) has advantages over conventional hearing aids in sound quality and speech reception in silence, but requires surgery and may have peri-and postoperative complications. We evaluated audiological findings and complications in 12 subjects (13 ears)-8 men and 4 women aged 20-71--undergoing BAHA surgery from September 2001 to October 2005. Surgery was for single-sided deafness in one subject. Mean warble tone thresholds with BAHA were 29.9dB and 65.2dB without. Functional gains ranged from 16 to 52dB (mean: 35.3dB). Dural exposure or venous hemorrhage was seen in 4 ears, and mastoid cells opened and a skin flap was damaged in 1 ear each. No severe complications occurred perioperatively. Skin reactions categorized into grade 1 or more were recognized in nearly 70% of ears during the first postoperative year but most were a grade 1 reaction and skin reactions decreased with time. Skin overgrowth occurred in 1 ear immediately after an abutment separated accidentally from the fixture. All complications were treated in outpatient clinics. No fixture extrusion occurred. The decision to proceed with BAHA surgery thus required fully informed consent based on knowledge of peri-and postoperative complications. PMID:21838056

Full Text Available OBJECTIVE: Sufficient self-esteem is extremely important for psychosocial functioning. It is hypothesized that hearing-impaired (HI children have lower levels of self-esteem, because, among other things, they frequently experience lower language and communication skills. Therefore, the aim of this study was to compare HI children's self-esteem across different domains with those of normal hearing (NH children and to investigate the influence of communication, type of education, and audiological characteristics. METHODS: This large (N = 252 retrospective, multicenter study consisted of two age- and gender-matched groups: 123 HI children and 129 NH controls (mean age = 11.8 years. Self-reports were used to measure self-esteem across four domains: perceived social acceptance by peers, perceived parental attention, perceived physical appearance, and global self-esteem. RESULTS: HI children experienced lower levels of self-esteem regarding peers and parents than NH controls. Particularly HI children who attended special education for the deaf were at risk, even after correcting for their language development and intelligence. Yet, levels of global self-esteem and self-esteem involving physical appearance in HI children equalled those of NH controls. Furthermore, younger age at implantation and longer duration of having cochlear implants (CIs were related to higher levels of self-esteem. CONCLUSION: HI children experience lower levels of self-esteem in the social domains. Yet, due to the heterogeneity of the HI population, there is high variability in levels of self-esteem. DISCUSSION: Clinicians must always be aware of the risk and protective factors related to self-esteem in order to help individual patients reach their full potential.

Full Text Available Objective: A national survey of early hearing detection and intervention services was undertaken to describe the current status of diagnostic and intervention services in the South African private health care sector.Methods: All private hospitals with obstetric units (n = 166 were surveyed telephonically. The data was integrated with data collected from self-administered questionnaires subsequently distributed nationally to private audiology practices providing hearing screening at the respective hospitals reporting hearing screening services (n = 87. Data was analysed descriptively to yield national percentages and frequency distributions.Results: Average reported age at diagnosis was 11 months. Most participants (74% indicated that less than 20% of infants fitted with hearing aids received amplification before the age of 6 months. Most (64% participants indicated that the average period between confirmed diagnosis and hearing aid fitting was 1 month, on par with international benchmarks. Only 16%–23% of participants included all diagnostic procedures recommended by the Health Professions Council of South Africa’s 2007 position statement for minimum diagnostic test batteries for infants and young children.Conclusions: Diagnosis of hearing loss, hearing aid fitting and audiological intervention is delayed significantly in the South African private health care sector. Improved services should include integrated systematic hospital-based screening as part of birthing packages with diagnostic referral to specialist paediatric audiologists for accurate assessment and management of patients in a timely manner.

Full Text Available Scope of the study: Vestibular pathology is a complex one, requiring a minute clinical evaluation, as well as numerous paraclinical investigations. The present study analyzes the contribution of the modern methods of vestibular and auditive investigation to the diagnosis of dizziness. Materials and method: The results of the investigations performed on 84 patients with peripheric vestibular syndrome, on whom a complete audiological and vestibular assessment had been also made, have been retrospectively analyzed. Results: Anamnestic data and the results of evaluation permitted classification of peripheric vestibular pathology according to topo-lesional and etiological criteria. The most frequently diagnosed diseases were: benign paroxysmal positional vertigo, Ménière syndrome and vestibular neuronitis. Conclusions: Testing of the vestibulo-ocular and vestibulo-spinal reflexes through videonystagmoscopy and, respectively, computerized dynamic posturography, besides tonal vocal audiometry and precocious auditive potentials, is especially important for a positive diagnosis and etiological differentiation of vestibular syndromes.

Objective Cleft palate increases the risk of chronic middle ear disease and hearing loss. The goal of this report was to determine which of two palate surgeries and which timing of palate surgery were associated with better otologic and audiologic outcomes in children with unilateral cleft lip and palate at 5 to 6 years of age. Design Subjects were randomly assigned to the von Langenbeck with intravelar veloplasty or Furlow palate repair, to palate surgery at 9 to 12 months or 15 to 18 months of age, and to the Spina or Millard lip repair. Setting Centralized, tertiary care craniofacial treatment center. Patients A total of 673 infants with unilateral cleft lip and palate. Interventions Palate and lip were repaired using established techniques. Serial otoscopic and audiometric evaluations were performed. Main Outcome Measures Hearing and otoscopic findings at 5 to 6 years old. Results There were 370 children available for analysis. Hearing and need for tympanostomy tube placement did not differ by palatoplasty, age at palatoplasty, cheiloplasty, or surgeon. Risk of developing cholesteatoma or perforation was higher with Millard cheiloplasty (odds ratio = 5.1, 95% confidence interval = 1.44 to 18.11, p = .012). Type and age at palatoplasty were not significantly associated with either the rate of developing these sequelae or the rate of achieving bilaterally normal hearing and ear examinations. Conclusions Type of palatoplasty did not influence otologic and audiologic outcomes in 5- to 6-year-olds with unilateral cleft lip and palate. The potential influence of lip repair on otologic outcomes warrants further investigation. PMID:20536371
My internship at Johnson Space Center, Houston TX comprised of working simultaneously in the Space Life Science Directorate (Clinical Services Branch, SD3) in Audiology and Hearing Conservation and in the Astromaterials Research and Exploration Sciences Directorate in the Orbital Debris Program Office (KX). The purpose of the project done to support the Audiology and Hearing Conservation Clinic (AuHCon) is to organize and analyze auditory test data that has been obtained from tests conducted onboard the International Space Station (ISS) and in Johnson Space Center's clinic. Astronauts undergo a special type of auditory test called an On-Orbit Hearing Assessment (OOHA), which monitors hearing function while crewmembers are exposed to noise and microgravity during long-duration spaceflight. Data needed to be formatted to assist the Audiologist in studying, analyzing and reporting OOHA results from all ISS missions, with comparison to conventional preflight and post-flight audiometric test results of crewmembers. Orbital debris is the #1 threat to manned spacecraft; therefore NASA is investing in different measurement techniques to acquire information on orbital debris. These measurements are taken with telescopes in different parts of the world to acquire brightness variations over time, from which size, rotation rates and material information can be determined for orbital debris. Currently many assumptions are taken to resolve size and material from observed brightness, therefore a laboratory (Optical Measurement Center) is used to simulate the space environment and acquire information of known targets suited to best model the orbital debris population. In the Orbital Debris Program Office (ODPO) telescopic data were acquired and analyzed to better assess the orbital debris population.

Full Text Available The public health challenge of hearing impairment is growing, as age is the major determinant of hearing loss. Almost one in four (22.6% over 75-year olds reports moderate or severe worry because of hearing problems. There is a 40% comorbidity of tinnitus and balance disorders. Good outcomes depend on early presentation and appropriate referral. This paper describes how the NHS Improvement Programme in England used service improvement methodologies to identify referral pathways and tools which were most likely to make significant improvements in diagnosing hearing loss, effective referrals and better patient outcomes. An audiometric screening device was used in GP surgeries to enable thresholds for effective referrals to be measured in the surgery. Revised referral criteria, the use of this device, new “assess and fit” technology in the audiology clinic, and direct access pathways can transform audiology service delivery so that patient outcomes are measurably better. This, in turn, changes the experience of GPs, so they are more likely to refer patients who can benefit from treatment. At the end of 2011, 51 GP practices in one of the audiology pilot areas had bought HearCheck screeners, a substantial development from the 4 practices who first engaged with the pilot.
Full Text Available Audiologists and speech-language therapists working in developing contexts like South Africa have the opportunity to address a range of needs through their research. One of these needs is the development of assessments and therapy materials that are appropriate for their clients’particular language needs and cultural background. This editorial paper aims to introduce original research in speech-language therapy and audiology, which has been carried out in South Africa and other developing contexts and is presented in this volume of the journal. In addition we suggest that while the focus of much research is on the destination or end product that is developed, there is a need to share the methodologies that are used to reach that goal so that more research can be carried out by a wider pool of students, researchers and clinicians. We describe some of the methods that we have used in our research – often in small scale projects with budgetary constraints, which would be feasible for clinicians in their routine clinical contexts. Our hope is that others can build on these approaches, critique and share their own strategies for the ultimate advancement of the professions in southern Africa.

Full Text Available Abstract Background Multi-drug resistant tuberculosis has emerged as a significant problem with the resurfacing of tuberculosis and thus the need to use the second line drugs with the resultant increased incidence of adverse effects. We discuss the effect of second line aminoglycoside anti-tubercular drugs on the hearing status of MDR-TB patients. Methods Sixty four patients were put on second line aminoglycoside anti-TB drugs. These were divided into three groups: group I, 34 patients using amikacin, group II, 26 patients using kanamycin and group III, 4 patients using capreomycin. Results Of these, 18.75% of the patients developed sensorineural hearing loss involving higher frequencies while 6.25% had involvement of speech frequencies also. All patients were seen again approximately one year after aminoglycoside discontinuation and all hearing losses were permanent with no threshold improvement. Conclusion Aminoglycosides used in MDR-TB patients may result in irreversible hearing loss involving higher frequencies and can become a hearing handicap as speech frequencies are also involved in some of the patients thus underlining the need for regular audiologic evaluation in patients of MDR-TB during the treatment.
Full Text Available While most tinnitus cases have some degree of hearing impairment, a small percent of the patients admitted to Ear, Nose and Throat Clinics or Hearing Evaluation Centers are those who complain of tinnitus despite having normal hearing thresholds. Present study was performed in order to better understanding of the probable causes of tinnitus and to investigate possible changes in the cochlear and auditory brainstem function in normal hearing patients with chronic tinnitus. Altogether, 63 ears (31 ears with tinnitus and 32 ears without tinnitus were examined. The prevalence of transient evoked otoacoustic emissions and characteristics of the auditory brainstem response components including wave latencies and wave amplitudes was determined in the two groups and analyzed with appropriate statistical methods. There was no difference between the prevalence of transient evoked emissions in the two groups. The mean difference between absolute latencies of waves I, III and V was less than 0.1 ms between the two groups that were not statistically significant. Also, the interpeak latency values of I-III, III-V and I-V in both groups had no significant difference. Only the V/I amplitude ratio in the tinnitus group was significantly larger than the other group (p =0.04. The changes observed in amplitude of waves, especially in the later ones, can be considered as an Audiologic finding in normal hearing tinnitus subjects and its possible role in generation of tinnitus in these patients must be investigated.

The sound in classical orchestral music is louder than noise emissions allowed by national rules in industry. We wanted to assess the audiologic status of professional musicians at different ages of their careers and to look for a coherence of declined hearing ability and the sound emissions in order to substantiate advices for hearing protection and occupational medicine in musicians. Data from questionnaires (anamnestic data on sound exposure in profession and leisure times, use of hearing protection, self-evaluation of hearing function and hearing deficits), audiometric data and amplitudes of OAE were evaluated from 109 professional musicians aged 30-69 years from three major German orchestras and from 110 students of an academy of music (aged 11-19 years). Sound emissions of the whole orchestra and of single instruments/instrument groups were measured at the orchestra stages and pits during rehearsals and performances. None of the musicians was engaged in noisy hobbies and only a few used hearing protectors regularly. More than 50% of the musicians had a hearing loss of 15 dB(A) and more. Highest losses were found among the strings and the brass players. DPOAE amplitudes coincidently declined with the duration of performing music in the orchestras. Professional musicians aged older than 60 years had a significantly greater hearing loss at 4 and 6 kHz than those aged 30-39 years. Among the strings in one orchestra a dominant hearing deficit in the left ears was observed. Musicians need the same health care for their hearing as workers in noisy industry. A better education on the hearing hazards (use of hearing protectors) as well as sound protection in the rehearsal rooms is necessary. Hearing loss in professional musicians should be accepted as an occupational disease. PMID:18034257

The purpose of this study was to determine the association of the mitochondrial genes RNR1, MT-TL1, and ND1 as well as the nuclear genes GJB2 and GJB6 with audiological examinations in nonfamilial Iranians with cochlear implants, using polymerase chain reaction, DNA sequencing, and RNA secondary structure analysis. We found that there were no novel mutations in the mitochondrial gene 12S rRNA (MT-RNR1 in patients with and without GJB2 mutation (GJB2+ and GJB2-, respectively, but a total of six polymorphisms were found. No mutations were observed in tRNALeu(UUR (MT-TL1. Furthermore, eight polymorphisms were found in the mitochondrial ND1 gene. Additionally, no mutations were observed in the nuclear GJB6 gene in patients in the GJB2- and GJB2+ groups. The speech intelligibility rating and category of auditory perception tests were statistically assessed in patients in the GJB2- and GJB2+ groups. The results indicated that there was a significant difference (P<0.05 between the categories of auditory perception score in the GJB2- group compared to that in the GJB2+ group. Successful cochlear implantation was observed among individuals with GJB2 mutations
Full Text Available Background: The objective of this study was to describe the audiologic and related characteristics of a group patient with speech perception affected out of proportion to pure tone hearing loss. A case series of patient were referred for evaluation and management to the Hearing Research Center.To describe the clinical picture of the patients with the key clinical feature of hearing loss for pure tones and reduction in speech discrimination out of proportion to the pure tone loss, having some of the criteria of auditory neuropathy (i.e. normal otoacoustic emissions, OAE, and abnormal auditory brainstem evoked potentials, ABR and lacking others (e.g. present auditory reflexes. Methods: Hearing abilities were measured by Pure Tone Audiometry (PTA and Speech Discrimination Scores (SDS, measured in all patients using a standardized list of 25 monosyllabic Farsi words at MCL in quiet. Auditory pathway integrity was measured by using Auditory Brainstem Response (ABR and Otoacoustic Emission (OAE and anatomical lesions Computed Tomography Scan (CT and Magnetic Resonance Image (MRI of brain and retrocochlea. Patient included in the series were 35 patients who have SDS disproportionably low with regard to PTA, absent ABR waves and normal OAE. Results: All patients reported the beginning of their problem around adolescence. Neither of them had anatomical lesion in imaging studies and neither of them had any finding suggestive of conductive hearing lesion. Although in most of the cases the hearing loss had been more apparent in the lower frequencies (i.e. 1000 Hz and less, a stronger correlation was found between SDS and hearing threshold at higher frequencies. These patients may not benefit from hearing aids, as the outer hair cells are functional and amplification doesn’t seem to help; though, it was tried for all. Conclusion: These patients share a pattern of sensory –neural loss with no detectable lesion. The age of onset and the gradual

Hearing impairment is highly prevalent in the older population, and it impacts communication and quality of life for both the people with the hearing difficulties and their significant others. In this article, typical audiological assessment and management of an older adult is contrasted with a best practice approach wherein the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework is applied. The aim of the comparison is to demonstrate how the ICF expands our focus: rather than merely focusing on impairment, we also consider the activities, participation, and contextual factors for both the person with the hearing impairment and his or her family. A case example of an older patient and her spouse is provided, and their shared experience of the patient's hearing impairment is mapped onto the ICF framework. Family-centered hearing care is recommended for individualizing care and improving outcomes for older patients and their families. PMID:27489398

Otoacoustic (EOA-T and cochlear palpebral reflex. For newborns, those who failed the hearing screening in one or both ears, were referred to a second evaluation. In the retest, while the EOA-T test result in not passing on one or both ears, the child was referred for evaluation and otorhinolaringology management. After completing the Auditory Evoked Potential test, the team of evaluators decided whether it should refer the child to investigate the mutation. When there was suspicion of hearing impairment we collected 3 mL of peripheral venous blood for the detection of mutation in the connexin 26 gene. RESULTS: we observed the presence of conductive hearing loss in 2 neonates (0.22% and sensorineural in 1 (0.11%. In children with sensorineural hearing loss we detected the presence of 35delG mutation. CONCLUSION: the audiological assessment in conjunction with molecular tests of the main GJB2 gene mutations in newborns with suspected hearing loss contributed to the rapid audiological diagnostic, seeking early intervention, educational and genetic counseling and prognosis of the child.

No studies to date have objectively assessed whether pinna morphology affects sound intensity detected within the external auditory canal (EAC). Commonly performed procedures on the EAC are carried out for acquired and congenital pathology, together with correction of ear deformities. Our aim was to use an experimental model to identify whether a relationship exists between pinna shape and its subsequent effect on the hearing subject. An anatomically accurate and life-size model made of rubber composite was used for this study. Serial sections (small wedge, defect open; small wedge, defect closed; large wedge, defect open; large wedge, defect closed [equivalent to a protruding ear]; and pinnectomy) were undertaken, and the sound intensity changes assessed at the junction between the EAC and middle ear (tympanic membrane position) using an AURICAL Plus (Otometrics; Taastrup, Denmark) sound processor. A statistically significant loss was demonstrated for wedge-excised models, which was greatest at 180° azimuth. This loss was significantly reduced when the wedge defects were closed. A statistically significant improvement was demonstrated in the protruding ("bat") ear model compared with the normal ear at 0° azimuth. In this model, gain in sound intensity is adversely affected by pinna wedge resection. Because this change may be increased in those with protruding ears, this factor is important to consider for all cosmetic and noncosmetic operations to the pinna, and it supports the notion that the pinna is not a simple funnel.

Pediatric audiologists lack evidence-based, age-appropriate outcome evaluation tools with well-developed normative data that could be used to evaluate the auditory development and performance of children aged birth to 6 years with permanent childhood hearing impairment. Bagatto and colleagues recommend a battery of outcome tools that may be used with this population. This article provides results of an evaluation of the individual components of the University of Western Ontario Pediatric Audiological Monitoring Protocol (UWO PedAMP) version 1.0 by the audiologists associated with the Network of Pediatric Audiologists of Canada. It also provides information regarding barriers and facilitators to implementing outcome measures in clinical practice. Results indicate that when compared to the Parents' Evaluation of Aural/Oral Performance of Children (PEACH) Diary, audiologists found the PEACH Rating Scale to be a more clinically feasible evaluation tool to implement in practice from a time, task, and consistency of use perspective. Results also indicate that the LittlEARS(®) Auditory Questionnaire could be used to evaluate the auditory development and performance of children aged birth to 6 years with permanent childhood hearing impairment (PCHI). The most cited barrier to implementation is time. The result of this social collaboration was the creation of a knowledge product, the UWO PedAMP v1.0, which has the potential to be useful to audiologists and the children and families they serve.

Full Text Available A audiometria de altas frequências (AAF é um exame audiológico importante na detecção precoce de perdas auditivas por lesões na base do ducto coclear. Nos últimos anos, a sua utilização foi facilitada pelo fato de os audiômetros comercializados passarem a incorporar frequências superiores a 8 kHz. Porém, existem diferenças relacionadas aos equipamentos utilizados, às metodologias empregadas e/ou aos resultados e interpretação. Assim, o objetivo deste artigo foi analisar a produção científica nacional sobre a aplicação clínica com AAF, para compreender sua utilização atual. Foram pesquisados textos publicados e indexados nas bases de dados LILACS, SciELO e Medline, num período de tempo de dez anos, utilizando como descritor "audiometria de altas frequências/high-frequency audiometry". Encontraram-se 24 artigos científicos nacionais utilizando AAF, cuja população avaliada, em sua maioria, apresentava de 18 a 50 anos de idade; 13 dos estudos determinaram os limiares utilizando como referência decibel nível de audição (dBNA; alguns estudos realizaram a comparação dos limiares auditivos tonais entre grupos para definir a normalidade; os autores relataram diferenças significativas nos limiares auditivos de altas frequências entre as idades. A AAF é utilizada na clínica audiológica para identificação precoce de alterações auditivas e no acompanhamento da audição de sujeitos expostos a drogas ototóxicas e/ou agentes otoagressores.High-frequency audiometry (HFA is an important audiological test for early detection of hearing losses caused by leasions in the base of the cochlear duct.

In my quest to become a better professor, I have been searching for the instructional paradigms that best facilitate the educational process between me and my students. To support this endeavor, I opted to study learning diversity. The results of my investigation led me to reflect upon whether my teaching strategies inadvertently engaged only a subset of my students. I believe that was the case. In this article, I will describe the experiential learning model, how I used it to measure my students' learning styles, and how I used the model to make my teaching more holistic. PMID:23739057

Full Text Available INTRODUCTION: Age Related Hearing Loss (ARHL is defined as loss of hearing in elderly persons not influe nced by the extraneous factors like noise trauma etc or intrinsic like CVS related diseases or endocrinal disorders like Diabetes. Also termed as Presbycusis it is defined as the loss of hearing due to age related changes taking place in the auditory syste m starting from the pinna to the cortical centers in the brain. It does not include any other factor contributing or initiating the pathological changes in the auditory system resulting in hearing loss. All these changes in the tissues are not pathological but truly age related. The threshold of hearing is defined as the pure tone average across the frequencies of 0.5 to 8 kHz. The severity of hearing loss is graded as profound hearing loss : more than 90dB , severe to severe loss : 71 - 90 dB or more ; Moderate to severe hearing loss : 56 - 70 , Moderate hearing loss : 41 - 55 dB HL ; Mild hearing loss : 26 - 40 dB HL. Present study is to evaluate hearing loss in persons aged above 65 years both of those attending the Hospital for loss of hearing and those screened in a sur vey. AIM: To evaluate the hearing thresholds in individuals aged above 65 years attending the Government General Hospital and among the people attending the hearing screening done in the city of Warangal. The study also includes the review of the literature on ARHL. MATERIALS AND METHODS: 185 individuals aged above 65 years are evaluated for hearing thresholds with the help of pure tone audiometry and speech audiometry. Among the 185 individuals 102 are patients attending the Department of ENT for the compla ints of loss of hearing. The remaining 83 individuals are from the survey conducted to screen for hearing loss in the city of Warangal for the population aged above 65 years. Demographic data about the 185 individuals is collected. Pure tone audiogram and speech audiometry is done in all the patients. CONCLUSIONS: PTA and SRT values are similar in both the groups. Early old age groups presented with mild to severe types of deafness and loss in lower frequencies. Late old aged people showed profound hearing l oss and increased thresholds in higher frequencies. SRT estimation seemed more sensitive than calculating PTA in the persons above 85 years. Females showed 5 to 10 dB lower PTA values than males in all ages.

Full Text Available Owing to technological progress and a growing body of clinical experience, indication criteria for cochlear implants (CI are being extended to less severe hearing impairments. It is, therefore, worth reconsidering these indication criteria by introducing novel testing procedures. The diagnostic evidence collected will be evaluated. The investigation includes postlingually deafened adults seeking a CI. Prior to surgery, speech perception tests [Freiburg Speech Test and Oldenburg sentence (OLSA test] were performed unaided and aided using the Oldenburg Master Hearing Aid (MHA system. Linguistic skills were assessed with the visual Text Reception Threshold (TRT test, and general state of health, socio-economic status (SES and subjective hearing were evaluated through questionnaires. After surgery, the speech tests were repeated aided with a CI. To date, 97 complete data sets are available for evaluation. Statistical analyses showed significant correlations between postsurgical speech reception threshold (SRT measured with the adaptive OLSA test and pre-surgical data such as the TRT test (r=-0.29, SES (r=-0.22 and (if available aided SRT (r=0.53. The results suggest that new measures and setups such as the TRT test, SES and speech perception with the MHA provide valuable extra information regarding indication for CI.

Assim, é importante que a investigação audiológica se associe à busca do diagnóstico etiológico. OBJETIVO: Relatar o perfil audiológico e genético de três irmãos portadores de deficiência auditiva neurossensorial não-sindrômica. MATERIAL E MÉTODO: Estudo de caso de três irmãos, do sexo masculino, com 3, 5 e 16 anos, respectivamente, submetidos à avaliação audiológica comportamental e eletrofisiológica, e estudo molecular. RESULTADOS: Os achados audiológicos mostraram: audiometria do tipo neurossensorial, bilateral, simétrica, de grau moderado a moderadamente severo e configuração descendente acentuada. EOAT e EOAPD ausentes nos dois irmãos mais novos. PEATE compatível com perda auditiva moderadamente severa a severa. Presença do P300 com latências dentro da normalidade bilateralmente no irmão mais velho. Os achados do exame molecular mostraram que as duas crianças mais novas eram heterozigotos para a mutação 35delG no gene GJB2 e o mais velho não apresentava essa mutação. CONCLUSÃO: A associação das avaliações fonoaudiológicas e genéticas permite o diagnóstico etiológico de perdas auditivas que à primeira vista são semelhantes, mas que não obedecem à mesma estrutura genética. Os estudos moleculares devem ser abrangentes, evitando diagnósticos precipitados que prejudiquem o aconselhamento genético.Hearing loss is a multifaceted condition with many etiologies, among which genetic mutation is.

Full Text Available Introduction: The most relevant clinical symptom in Waardenburg syndrome is profound bilateral sensorioneural hearing loss. Aim: To characterize and describe hearing outcomes after cochlear implantation in patients with Waardenburg syndrome to improve preoperative expectations. Method: This was an observational and retrospective study of a series of cases. Children who were diagnosed with Waardenburg syndrome and who received a multichannel cochlear implant between March 1999 and July 2012 were included in the study. Intraoperative neural response telemetry, hearing evaluation, speech perception, and speech production data before and after surgery were assessed. Results: During this period, 806 patients received a cochlear implant and 10 of these (1.2% were diagnosed with Waardenburg syndrome. Eight of the children received a Nucleus 24® implant and 1 child and 1 adult received a DigiSonic SP implant. The mean age at implantation was 44 months among the children. The average duration of use of a cochlear implant at the time of the study was 43 months. Intraoperative neural responses were present in all cases. Patients who could use the speech processor effectively had a pure tone average of 31 dB in free-field conditions. In addition, the MUSS and MAIS questionnaires revealed improvements in speech perception and production. Four patients did not have a good outcome, which might have been associated with ineffective use of the speech processor. Conclusion: Despite the heterogeneity of the group, patients with Waardenburg syndrome who received cochlear implants were found to have hearing thresholds that allowed access to speech sounds. However, patients who received early intervention and rehabilitation showed better evolution of auditory perception.

Full Text Available Objective. 312 tinnitus sufferers were studied in order to analyze: the clinical characteristics of tinnitus; the presence of tinnitus-age correlation and tinnitus-hearing loss correlation; the impact of tinnitus on subjects' life and where possible the etiological/predisposing factors of tinnitus. Results. There is a slight predominance of males. The highest percentage of tinnitus results in the decades 61–70. Of the tinnitus sufferers, 197 (63.14% have a hearing deficit (light hearing loss in 37.18% of cases. The hearing impairment results of sensorineural type in 74.62% and limited to the high frequencies in 58.50%. The tinnitus is referred as unilateral in 59.93%, a pure tone in 66.99% and 10 dB above the hearing threshold in 37.7%. It is limited to high frequencies in 72.10% of the patients with sensorineural hearing loss (SNHL while the 88.37% of the patients with high-frequency SNHL have a high-pitched tinnitus (2=66.26;<.005. Conclusion. Hearing status and age represent the principal tinnitus related factors; there is a statistically significant association between high-pitched tinnitus and high-frequency SNHL. There is no significant correlation between tinnitus severity and tinnitus loudness confirming the possibility that neural connection involved in evoking tinnitus-related negative reactions are governed by conditioned reflexes.

presented normal results in pure-tone and speech audiometry; however, speech discrimination scores were lower on the phenylketonuria group. Immitance tests revealed normal tympanograms for all children, but stapedial reflex thresholds demonstrated higher thresholds in 2 and 4 kHz for children with phenylketonuria. The suppresion of transient otoacoustic emissions did not show difference in the comparison between groups. CONCLUSION: The basic audiologic assessment do not identify hearing disorders in children with phenylketonuria; however, speech discrimination scores were lower and stapedial reflexes were higher in these children, which may indicate auditory processing disorders. The study of the suppression of transient otoacoustic emissions demonstrated integrity of the olivocochlear efferent system in children with phenylketonuria.

São Paulo, Brazil - DERDIC PUC-SP, that took part in a rehabilitation program from 1999 to 2002. METHODS: a retrospective study of 162 files of hearing impaired children between 12mo and 17:6 yrs old, the questionnaire elaborated by The Aural Rehabilitation Forum which occurs annually during the International Audiology Meeting in Brazil was used. RESULTS: the results showed 54% male and 46% female subjects; 60% between 3 and 8:11 years old; 43% had the suspicions of the hearing loss in the first year of life; for 25% of the subjects the diagnostic was carried out just after the suspicions; 34% finished the diagnostic one year after the suspicions; 11% began rehabilitation just after the diagnostic, 54% after a year and 27% more than a year. 32% had unknown etiology, 18% genetic causes, 17% presumed multiple factors, 15% meningitis, 9% congenital rubella. CONCLUSION: the prevalence of unknown etiology shows the need for deepening the diagnosis, and as a routine, carry out genetics, images and laboratories studies, in order to know the etiologies of the hearing loss. Even though after implementing immunization campaigns, rubella was the most prevalent cause of the congenital hearing loss and meningitis was the most prevalent cause of acquired hearing loss. A precious time for the child development was lost because of the time gap between suspicions, diagnostic and rehabilitation.

Full Text Available O artigo relata experiência de atuação fonoaudiológica baseada nos pressupostos da educação em saúde direcionada à promoção do aleitamento exclusivo em prematuros internados em uma maternidade de referência em alto risco. No trabalho desenvolvido, estratégias multiprofissionais realizadas com grupos e de forma individualizada foram combinadas, criando espaços dialógicos com as puérperas e seus familiares e a prevalência de aleitamento materno exclusivo aumentou nos últimos três anos na enfermaria. Houve grande participação dos envolvidos nas atividades propostas, desde a admissão da puérpera na enfermaria ao processo da alta hospitalar. A estratégia adotada permitiu detectar as intervenções mais efetivas e as que deverão ser reformuladas com toda equipe. Do ponto de vista teórico e metodológico, a experiência também permitiu observar os limites e potencialidades de ações que aproximam a área do saber científico e a promoção do aleitamento materno efetiva em atividades transdisciplinares. Considerar a educação em saúde como disciplina de ação significa dizer que o trabalho é dirigido para atuar sobre o conhecimento das pessoas, para que elas desenvolvam juízo crítico e capacidade de intervenção sobre suas próprias vidas e sobre o ambiente com o qual interagem e, assim, criarem condições para se apropriarem de sua própria existência.This paper reports an experience of a speech-language and audiology (SLP team based on health promotion and education to contribute for the maintainance of exclusive breastfeeding in premature newborns in a high-risk maternity.

Summary Introduction: Currently, the Brazilian government has certificated nearly 140 specialized centers in hearing aid fittings through the Brazilian National Health System (SUS). Remote fitting through the Internet can allow a broader and more efficient coverage with a higher likelihood of success for patients covered by the SUS, as they can receive fittings from their own homes instead of going to the few and distant specialized centers. Aim: To describe a case of remote fitting between 2 cities, with revision of the literature. Method: Computer gears, a universal interface, and hearing aids were used. Case study: An audiologist located in a specialized center introduced a new hearing aid and its fitting procedure to a remote center (200 km away). The specialized center helped the remote center in fitting a hearing aid in 2 patients, and performed fitting in one of its own patients. The whole process was done through the Internet with audio and video in real time. Results: Three patients were fitted remotely. Three audiologists were remotely trained on how to fit the hearing aids. Conclusions: Remote fitting of hearing aids is possible through the Internet, as well as further supplying technical training to a remote center about the fitting procedures. Such a technological approach can help the government advance public policies on hearing rehabilitation, as patients can be motivated about maintaining their use of hearing aids with the option to ask for help in the comfort of their own homes.

Users of a single-channel intracochlear implant (CI, n = 10) (3M/House), a single-channel vibrotactile aid (V, n = 8) (Minivib 3/Special Instrument Ab) and acoustic hearing aids (HA, n = 9) were tested. The comparison was made after training and a minimum of 11 months' use of the devices. All subjects were considered profoundly deaf, but the HA group had some residual hearing. The HA group achieved the best mean test scores in all the tests given. The difference between the CI group and V group increased, in favour to the CI users, as the auditory task was changed from the level of simple signal analysis to the level of linguistic interpretation.

Background: CHARGE syndrome is a common congenital anomaly. Hearing loss affects 60%-90% of these children. As temporal bone computed tomography (CT) has become more sophisticated, more abnormalities of the middle and inner ear have been found. We present the detailed CT findings for children with CHARGE syndrome and the correlation of the CT findings with audiograms. Methods: We performed a retrospective medical records review of 12 patients with CHARGE syndrome, identified between 1990-2011 at Princess Margaret Hospital for Children in Western Australia, who underwent temporal bone CT for evaluation of hearing loss. Results: We present our findings for the 24 ears in terms of the cochlear, semicircular canal, middle ear, facial nerve, external auditory canal, venous, and jugular anomalies. The internal auditory canal was normal in 83.3% (n=20) of ears. Three (12.5%) ears had enlarged basal turns, and 4 (16.7%) each had hypoplastic and incompletely partitioned apical turns. The majority (n=13, 56.5%) of the vestibules were dysplastic. Up to 70.8% had abnormalities of the semicircular canal. The middle ear cavity was normal in 55% (n=11) of ears; however, up to 80% of the ears had some abnormality of the ossicles, and up to 70% had an abnormality of the facial nerve (7th cranial nerve) segments, especially in the labyrinthine segment. CT findings did not correlate with the audiograms. Conclusion: The management of children with CHARGE syndrome is complex, requiring early evaluation and close attention of the multidisciplinary team. Early identification of hearing deficits is vital for patients' linguistic development. PMID:27303220

The whole process was done through the Internet with audio and video in real time. Results: Three patients were fitted remotely. Three audiologists were remotely trained on how to fit the hearing aids. Conclusions: Remote fitting of hearing aids is possible through the Internet, as well as further supplying technical training to a remote center about the fitting procedures. Such a technological approach can help the government advance public policies on hearing rehabilitation, as patients can be motivated about maintaining their use of hearing aids with the option to ask for help in the comfort of their own homes.
Full Text Available We studied 49 patients with partial epilepsy divided into lesional cases (i.e. with lesions on CT scan and non-lesional cases (i.e. without CT scan lesions, in relation to the Wechsler Intelligence Scale subtests (Coding, Digit span, dichotic listening CV task and Central Auditory Test (SSI, PSI. The aim of this paper was to study the hemispheric prevalence in dichotic listening task with regard to cognitive perforamance, as well as the presence or absence of central auditory dysfunction. Lesional cases presented a hemisphere prevalence in dichotic listening task with regard to cognitive performance, as well as the non-lesional cases tend to report the stimuli in the same side of EEC focus. Significant differences were found among the lesional and non lesional cases in relation to the digit span score and Coding subtest in right lesional cases versus right non-lesional cases. Both lesional and non-lesional group showed signs of central auditory dysfunction. We suggest that the dichotic listening and SSI and PSI test can be useful for a best comprehension of asymmetric neuropsychological performance in partial epilepsy.

Full Text Available In this editorial introduction we aim to explore the notion of contextually-relevant resources. We argue that it is the responsibility of Speech Language Therapists (SLTs and Audiologists (As working in South Africa to develop contextually relevant resources, and not to rely on the countries or cultures where the professions originated to do so. Language is often cited as the main barrier to contextually relevant resources: most SLTs and As are aware of the need for more resources in the indigenous local languages. However, the issue is not as straightforward as translating resources from English into other languages. The challenges related to culture, e.g. formal education, familiarity with the test situation, have to be considered; as well as the population on which norms were obtained; the nature of vocabulary or picture items. This paper introduces four original research papers that follow in this edition of the journal, and showcases them as examples of innovative development in our field. At the same time we call for the further development of assessment materials, intervention resources, and contributions to the evidence base in our context. We emphasise the importance of local knowledge to drive the development of these resources in innovative and perhaps unexpected ways, and suggest that all clinicians have an important role to play in this process.

The affects of noise on the human inner ear have been well known for a long time, and measures to prevent occupational noise-induced hearing loss show a clear reduction in the statistics of morbidity. Nevertheless, there are working environments in which the use of ear protection seems to be inapplicable, because communication by speech is indispensable, for example in the cockpit of aircraft. Noise exposure measurements were performed on pilots of helicopters and propeller-machines of the German Federal Navy during realistic flight situations. The ambient noise levels during regular flight service were maintained at levels between 89 dB and 120 dB. Sound protection by flight-helmets and headphones is not only neutralised while using radio and intercom, but the noise during radio-communication is even louder than the noise of the engines. The use of ear protection to avoid excessive noise exposure is only of limited effectiveness. While pilots with normal hearing show only little impairment of speech intelligibility, those with noise-induced hearing loss show substantial impairment that varies in proportion to their hearing loss. Communication abilities may be drastically reduced which may compromise the reliability of radio-communication. The problem may be possibly solved in future by an electronic compensation system for noise. PMID:3429278

Full Text Available Swallowing disorders are frequent. The main concern is mortality due to aspiration-induced pneumonia and malnutrition. In addition, quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract, and sequelae of tumor treatment in the head and neck region are the main pathologic entities.Predominantly ENT physicians and phoniatricians are asked for diagnostics and therapy, and will coordinate the interdisciplinary treatment according to the endoscopic findings.A differentiated approach in history, diagnostics, and symptom-oriented treatment is necessary for these mostly complex disorders. Integration of non-medical staff such as speech therapists, physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over in close cooperation.In particular, an interdisciplinary cooperation with the staff of intensive care medicine is essential.The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists.Endoscopy is a medical service that is basically not delegable. Consequently, substitution of the physician is excluded.

The foremost, dominant, and influential scientific discourse of how to define tinnitus states that tinnitus is the perception of sound(s) in the absence of an external sound source. This is the most common statement among researchers in audiology and related fields, stemming from basic neurosciences (Kaltenbach, 2011) to applied psychophysiology (Kropp et al., 2012), audiology (Caffier et al., 2006), and behavioural psychology (Westin et al., 2008). It is puzzling that scientific affiliation ...

This paper is primarily concerned with handicap, which emphasises the psychosocial consequence of hearing loss, its development and a framework for its alleviation. The development of handicap is considered, taking as a starting point the World Health Organization Definitions of disablements and their application to audiology by Stephens and Hétu (1991). This is extended in the light of recent work on the role of significant others and of positive experiences arising from the hearing loss. This approach is then incorporated into an update of the Goldstein/Stephens (1981) management model of audiological rehabilitation which provides a framework applicable in any sociomedical situation.

. The paper shows how recent changes in perception of the hearing impaired patient relate to the introduction of a new health care reform that turns audiological rehabilitation into a consumer issue. Ethnographic and interview data from hearing clinics provides evidence that the hearing technologies...... that are on offer stabilise in specific forms through processes of negotiation among a variety of social actors representing the interests of science, industry, government, and hearing-impaired people. The discussion critically considers the emergence of an ‘‘informed consumer’’ in audiological practices....

A decision support system (DSS) is used for analysing a situation and making decisions. The goal of this research is to mine a large set of heterogeneous audiology data and create a DSS to help audiology technicians to choose between an ITE or BTE hearing aid. Although, in many cases such a choice is clear cut, but at other times this system could be used as a second opinion to predict the hearing aid type. A number of data mining techniques, such as clustering of audiograms, association anal...

Full Text Available Background: Hearing loss is a prevalent and significant disability that impairs functional development and educational attainment of school children in developing countries. Lack of a simple and practical screening protocol often deters routine and systematic hearing screening at school entry. Aim: To identify predictors of hearing loss for a practical screening model in school-aged children. Settings and Design: Community-based, retrospective case-control study of school entrants in an inner city. Methods: Results from the audiologic and non-audiologic examination of 50 hearing impaired children in randomly selected mainstream schools were compared with those of a control group of 150 normal hearing children, matched for age and sex from the same population. The non-audiologic evaluation consisted of medical history, general physical examination, anthropometry, motor skills, intelligence and visual acuity while the audiologic assessment consisted of otoscopy, audiometry and tympanometry. Statistical Analysis: Multiple logistic regression analysis of significant variables derived from univariate analysis incorporating student t-test and chi-square. Results: Besides parental literacy (OR:0.3; 95% CI:0.16-0.68, non-audiologic variables showed no association with hearing loss. In contrast, most audiologic indicators, enlarged nasal turbinate (OR:3.3; 95% CI:0.98-11.31, debris or foreign bodies in the ear canal (OR:5.4; 95% CI:1.0-36.03, impacted cerumen (OR:6.2; 95% CI:2.12-14.33, dull tympanic membrane (OR:2.2; 95% CI:1.10-4.46, perforated ear drum (OR:24.3; 95% CI:2.93-1100.17 and otitis media with effusion OME (OR:14.2; 95% CI:6.22-33.09, were associated with hearing loss. However, only parental literacy (OR:0.3; 95% CI:0.16-0.69, impacted cerumen (OR:4.0; 95% CI:1.66-9.43 and OME (OR:11.0; 95% CI:4.74-25.62 emerged as predictors. Conclusion: Selective screening based on the identification of impacted cerumen and OME will facilitate the

The development of hearing aids incorporates two aspects, namely, the audiological and the technical point of view. The former focuses on items like the recruitment phenomenon, the speech intelligibility of hearing-impaired persons, or just on the question of hearing comfort. Concerning these subjects, different algorithms intending to improve the hearing ability are presented in this paper. These are automatic gain controls, directional microphones, and noise reduction algorithms. Besides the audiological point of view, there are several purely technical problems which have to be solved. An important one is the acoustic feedback. Another instance is the proper automatic control of all hearing aid components by means of a classification unit. In addition to an overview of state-of-the-art algorithms, this paper focuses on future trends.

Full Text Available Introduction: The effects of lead on children's health have been widely studied. Aim: To analyze the correlation between the long latency auditory evoked potential N2 and cognitive P3 with the level of lead poisoning in Brazilian children. Methods: This retrospective study evaluated 20 children ranging in age from 7 to 14 years at the time of audiological and electrophysiological evaluations. We performed periodic surveys of the lead concentration in the blood and basic audiological evaluations. Furthermore, we studied the auditory evoked potential long latency N2 and cognitive P3 by analyzing the absolute latency of the N2 and P3 potentials and the P3 amplitude recorded at Cz. At the time of audiological and electrophysiological evaluations, the average concentration of lead in the blood was less than 10 ug/dL. Results: In conventional audiologic evaluations, all children had hearing thresholds below 20 dBHL for the frequencies tested and normal tympanometry findings; the auditory evoked potential long latency N2 and cognitive P3 were present in 95% of children. No significant correlations were found between the blood lead concentration and latency (p = 0.821 or amplitude (p = 0.411 of the P3 potential. However, the latency of the N2 potential increased with the concentration of lead in the blood, with a significant correlation (p = 0.030. Conclusion: Among Brazilian children with low lead exposure, a significant correlation was found between blood lead levels and the average latency of the auditory evoked potential long latency N2; however, a significant correlation was not observed for the amplitude and latency of the cognitive potential P3.

Full Text Available OBJECTIVE: To investigate whether there is any relationship between otological as well as vestibular symptoms, audiological findings and type of temporomandibular disorder (articular, muscular and mixed; and to check the distribution of the temporomandibular disorders (TMD dysfunction degree in the research population. METHODS: A retrospective study involving 30 patients of both sexes, aged between 18 and 49 years old, diagnosed with TMD and dentofacial deformities, who were subject to clinical evaluation (muscle palpation, auscultation of temporomandibular joint during mandibular motion and measurement of jaw movement, audiological testing (pure tone audiometry and immittance testing and two questionnaires, one on otological and vestibular symptoms and the other on TMD anamnesis. Based on both the anamnesis questionnaire and the clinical assessment, the subjects were divided according to the type and degree of TMD dysfunction (mild, moderate and severe, and compared regarding the occurrence of auditory signs and symptoms, vestibular symptoms and audiological findings according to TMD type. RESULTS: The anamnesis questionnaire demonstrated higher prevalence (83.33% of severe TMD. Subjects with mixed TMD had more complaints about hypoacusis than those with muscular TMD (p < 0.05. The results showed no change in either audiological and immittance testing for all assessed individuals. CONCLUSION: Otological symptoms are present in subjects with TMD and dentofacial deformities, regardless of the classification of TMD (articular, muscular or mixed. Those with mixed TMD may have higher incidence of complaints about hypoacusis than subjects with muscular TMD. Further studies are needed to investigate the relationship between otological symptoms and the different types of TMD.

The author of this article reviews various techniques in the auditory assessment of infants and young children. The success of these tests depends on the overall functioning of the child, and not on chronological age alone. Any significant deviation from the normal auditory behaviour should raise suspicion of possible auditory impairment. Diagnostic audiology involves more than mere testing of the peripheral auditory mechanism in isolation. It necessitates investigation of possible neurologic...

Distortion product otoacoustic emissions (DPOAEs) reflect outer hnir cell integrity and cochlear function. When used appropriately in the audiology clinic, they are an effective diagnostic tool and can detect hearing loss with accuracy. DPOAEs are easily and rapidly recorded in newborns and children, and provide basic hearing screening information as well as detailed diagnostic information in cases of suspected hearing loss. In the past decade, solid guidelines hnve been established to select...
The processes of hearing the sounds and speech are not yet explicable enough, and therefore rehabilitation audiology is continuously facing practical problems of hearing and speech stimulation with heavy out of hearing children. Hearing successes with children who have implanted cochlear apparatus may indicate to resonance problem, rather than damaged nerve cells problem with deaf children, as it is alleged today. This paper presents a new theory (the theory of resonance rehabilit...

Tinnitus is one of the major audiological diseases, affecting a significant portion of the ageing society. Despite its huge personal and presumed economic impact there are only limited therapeutic options available. The reason for this deficiency lies in the very nature of the disease as it is deeply connected to elementary plasticity of auditory processing in the central nervous system. Understanding these mechanisms is essential for developing a therapy that reverses the plastic changes und...

Noise exposure may result in production of auto-antibodies against heat shock proteins (Hsps), which might be of significance in the pathogenesis or prognosis (or both) of auto-immune ear diseases. However, it is not known whether these antibodies are associated with noise-induced hearing loss (NIHL) in workers exposed to noise in occupational settings. Using immunoblotting with human recombinant Hsps, audiological assessment, and multivariate logistic regression models, we investigated the p...

Pharmacotherapy-induced ototoxicity is growing, especially in developing countries such as South Africa. This highlights the importance of ototoxicity monitoring and management of hearing loss. This article focuses on the establishment of an ototoxicity clinic as a site for the implementation of a service-learning module in the Audiology programme. The clinic offers a unique opportunity of collaboration between pharmacists and an audiologist where pharmacotherapy-induced ototoxicity is uniquely monitored. The Sefako Makgatho Health Sciences University (SMU) provides training to both the disciplines, audiology and pharmacy. The main aim of this article is to describe how ototoxicity monitoring is implemented in the curriculum within such an academic service-learning approach. Through service learning students develop a deeper understanding of course content, acquire new knowledge and engage in civic activity. It simultaneously provides a unique opportunity for interdisciplinary collaboration between the disciplines of audiology and pharmacy. The objectives for this programme are therefore to facilitate learning and to provide a service to the local community by identifying, preventing and monitoring medicine-induced hearing loss in in-hospital and out-patients; as well as to establish inter-disciplinary collaboration between the disciplines and stakeholders for more effective service delivery. The constant interdisciplinary teamwork between the audiologist, pharmacist, physician and nursing staff in the wards results in best practice and management of patients with ototoxic damage.

Full Text Available Introduction: Tinnitus and hyperacusis are increasingly frequent audiological symptoms that may occur in the absence of the hearing involvement, but it does not offer a lower impact or bothering to the affected individuals. The Medial Olivocochlear System helps in the speech recognition in noise and may be connected to the presence of tinnitus and hyperacusis. Objective: To evaluate the speech recognition of normal-hearing individual with and without complaints of tinnitus and hyperacusis, and to compare their results. Method: Descriptive, prospective and cross-study in which 19 normal-hearing individuals were evaluated with complaint of tinnitus and hyperacusis of the Study Group (SG, and 23 normal-hearing individuals without audiological complaints of the Control Group (CG. The individuals of both groups were submitted to the test List of Sentences in Portuguese, prepared by Costa (1998 to determine the Sentences Recognition Threshold in Silence (LRSS and the signal to noise ratio (S/N. The SG also answered the Tinnitus Handicap Inventory for tinnitus analysis, and to characterize hyperacusis the discomfort thresholds were set. Results: The CG and SG presented with average LRSS and S/N ratio of 7.34 dB NA and -6.77 dB, and of 7.20 dB NA and -4.89 dB, respectively. Conclusion: The normal-hearing individuals with or without audiological complaints of tinnitus and hyperacusis had a similar performance in the speech recognition in silence, which was not the case when evaluated in the presence of competitive noise, since the SG had a lower performance in this communication scenario, with a statistically significant difference.
INTRODUCTION: Hearing screening programmes aim to detect hearing loss in the neonate. The Health Service Executive (HSE) South was the first phase of a national roll-out of a neonatal hearing screening programme in Ireland, going live on 28 April 2011. RESULTS: Over 11,738 babies have been screened for permanent childhood hearing impairment (PCHI) during the first 12 months. The percentage of eligible babies offered hearing screening was 99.2 %. Only 0.2 % (n = 25) of those offered screening declined. 493 (4 %) were referred for immediate diagnostic audiological assessment. The average time between screen and diagnostic audiology appointment was 2 weeks. 15 (1.3\\/1,000) babies have been identified with a PCHI over the 12-month period. 946 (4 %) babies screened were admitted to the neonatal intensive care unit (NICU) for >48 h. The prevalance of PCHI is 7.3\\/1,000 in the NICU population compared to 0.6\\/1000 in the well baby population. 214 (1.8 % of total babies screened) had a clear response in the screening programmes, but were deemed to be at risk of an acquired childhood hearing impairment. These babies will be reassessed with a diagnostic audiology appointment at 8-9 months of age. To date, there is one case of acquired hearing impairment through this targeted follow-up screen. Of the 15 cases of PCHI identified, 8 (53 %) of these had one or more risk factors for hearing loss and 7 (37 %) were admitted to the NICU for >48 h. Four babies were referred for assessment at the National Cochlear Implant Centre.

CHARGE syndrome is a rare, polymalformative disease, representing one of the major causes of associated blindness and deafness. Bilateral, severe-profound, sensorineural hearing loss is common in CHARGE children. Aim of this study is to present our results in children with "CHARGE syndrome" submitted to cochlear implantation (CI). The frequency of anatomic anomalies, possible variations in the surgical technique of CI, and the audiological/rehabilitative benefits attained in our patients are reported. we submitted 5 children affected by CHARGE syndrome with profound, bilateral, sensorineural hearing loss to CI. Otoacoustic emissions, auditory brainstem response, acoustic impedance testing, cranial computed tomography and magnetic resonance were carried out preoperatively in all children. CI was performed using the mastoidotomy-posterior tympanotomy approach in two cases, and the suprameatal approach in three children. Infant toddler-meaningful auditory integration scale was used to evaluate kid's audiological performance before and after CI. Intra-operatory findings and postsurgical complications were evaluated. Among our patients, intraoperative anatomical malformations were cochlear hypoplasia (100 %), ossicles malformations (100 %), semicircular canals aplasia (100 %), oval window atresia (60 %), round window atresia (40 %), widening of the aqueduct of the vestibule (20 %), and aberrant course of the facial nerve (20 %). No intra- or postoperative complication was recorded in relation to implant positioning. After a follow-up ranging from 1 to 4.5 years, only 2/5 patients used oral language as the sole mean of communication, 1 started utilizing oral language as the main mean of communication, while 2 patients did not develop any linguistic ability. In conclusion, CI in patients with CHARGE association is feasible and, despite results variability, it should be carried out in CHARGE children with severe hearing loss as soon as possible.

Detection of congenital or infantile hearing loss is often delayed in otherwise normal children, but even greater delays occur in the multihandicapped. Neonatal hearing screening and high risk register techniques have not had universal acceptance. A collaborative project between medical school otology and audiology personnel and a school for multihandicapped children under the age of 3 years in the Department of Special Education in another university has significantly reduced detection time and provided speech, language and other remedial therapy while otologic diagnosis and educational functional assessment proceed. The investigators and staff are bilingual. Parents learn to observe and work with their own child at the school and in the home. PMID:6192106

Between 40 and 90% of tympanoplasty require middle ear ossicular chain reconstruction. Ossicular discontinuity usually cannot be determined unless an operation is performed. The main objective was to determine the predictive value of pre-operative audiological factors in diagnosing incudal necrosis in patients with tubotympanic chronic suppurative otitis media. A retrospective clinical study of 20 patients who underwent ossicular reconstruction with autologous incus over a period of two years was performed. The mean pre-operative pure tone average was 49.18 dB HL.The minimum value being 45 dB HL and the maximum value being 64 dB HL. PMID:24294583

A 38-year-old female patient experienced a sudden onset of unilateral sensorineural hearing loss due to Moyamoya disease. A detailed summary of audiological and neurological findings indicated that the sudden hearing loss might be due to Moyamoya disease resulting in occlusion of posterior and middle cerebral arteries. Intravenous prednisolone and trimetazidine dihydrochloride may improve hearing thresholds and speech understanding. To our knowledge, this is the first article in the literature reporting a case of sudden hearing loss as the first manifestation of Moyamoya disease in a young adult. PMID:26890714

The past decade has seen the widespread introduction of universal neonatal hearing screening (UNHS) programmes worldwide. Regrettably, such a programme is only now in the process of nationwide implementation in the Republic of Ireland and has been largely restricted to one screening modality for initial testing; namely transient evoked otoacoustic emissions (TEOAE). The aim of this study is to analyse the effects of employing a different screening protocol which utilises an alternative initial test, automated auditory brainstem response (AABR), on referral rates to specialist audiology services.

Management of children with severe, severe-profound, and profound sensorineural hearing loss is best achieved using a family-centered approach by a team of health professionals, including audiologists, speech pathologists, otolaryngologists, pediatricians, genetic counselors, and early intervention programs. Early diagnosis and intervention offers the best chance for speech and language acquisition. Although hearing aids can provide some of the needed information, they are often not sufficient for spoken language development and a cochlear implant is needed. This must be combined with a strong audiology and speech therapy rehabilitation program. PMID:26293693

Annual hearing tests are compulsory in the British Armed Forces. This case report presents a 24-year old soldier who was found to have severe deterioration on her annual audiogram without any significant noise exposure. After two years of specialist audiological investigations she was diagnosed with non-organic hearing loss; further interrogation of her social circumstances suggested potential psychosocial triggers. This diagnosis should be considered early in military primary care in those with objective hearing loss on audiogram where there has been no exposure to significant noise. PMID:23402072
Full Text Available A twenty-eight-year-old woman with an eight-year history of partial hearing loss presented with a two-year history of worsening deafness and new-onset seizures. Evaluations of tympanic membranes, cochlea, and auditory brain stem reflexes demonstrated no physiologic basis for deafness. Video-EEG monitoring demonstrated that the patient responded normally to spontaneous auditory stimuli and that typical spells were nonepileptic in origin. Although pseudohypacusis is reported in audiology literature, and psychogenic nonepileptic spells are well-studied phenomena in neurology literature, the present case is an unusual case of dual psychogenic symptoms, a relationship that indicates poorer prognosis.

Full Text Available The hearing loss in a cleft patient is a well known complication, but generally gets ignored. These children continue to have recurrent otitis media with effusion that affects the hearing abilities. Unfortunatley the middle ear function may not improve with palatoplasty.Cleft palate teams need to follow up all such children beginning at birth and going into adulthood, decades after a ′successful′ palate repair. These patients should have careful otological and audiological surveillance with appropriate interventions whenever required. The review article discusses the current status of hearing management in patients with cleft palate.

We used a novel approach allowing participants in this study to self-monitor their hearing sensitivity to familiar sounds in the environment. The objective of this approach was to establish whether participants in the 80-89 and 90-99 age groups would recognize the degree of their hearing impairment. It was our hope that participants would value audiology treatment and that it would improve their quality of life over a short period. The pilot study took place in a clinical environment where participants answered survey questions before and after audiology treatment, which pertained to their hearing impairment, morale, social support, and life satisfaction. Caregivers were included in the research to rate and record participants' problem behaviors (e.g., shouting, anger, agitation, repetitive speech dialog, and depression) before, during, and after treatment. This research validates other scientists' findings that annoying problem behaviors may actually be the result of hearing loss because of a person's inability to recognize speech. The pilot study shows that participants with mild dementia adapted well to speech and sounds in the natural environment without agitation as well as to management of hearing aids within a 30-day period. The participants with moderate dementia were slower to adapt. All participants with dementia required the cooperation of their caregivers to maintain hygiene of ear canals and hearing aids and insertion. This study suggests that the sooner people receive treatment for hearing loss, the quicker they are to recognize speech and to master hearing aid technology. PMID:23072178
The objective of this cross-sectional study is to compare bone-conducted low-frequency hearing thresholds (BClf) to cervical vestibular evoked myogenic potentials (cVEMPs) findings in prelingual adult deaf patients. The fifty participants (100 ears) included twenty healthy controls and thirty other subjects selected from patients who presented with bilateral prelingual deafness to Department of Audiology of Hamadan University of Medical Sciences and Health Services (Hamadan, Iran). Assessments comprised of audiological evaluations, cVEMPs, and computerized tomography scans. Twenty deaf patients (forty affected ears) with bilateral decreased vestibular excitability as detected by abnormal cVEMPs revealed that BClf hearing thresholds were completely absent. Ten deaf patients (twenty unaffected ears) with normal cVEMPs reported a sensation of the sound at BClf hearing thresholds (the mean for 250 Hz=41 dBHL and for 500 Hz=57.75 dBHL). Multiple comparisons of mean p 13 latencies, mean n23 latencies and peak-to-peak amplitudes between three groups were significant (P = 0.01 for all, one-way ANOVA test). Multiple Comparisons of mean BClf between three groups were significant (P = 0.00, One-way ANOVA test). Conclusion. Hypersensitivity of vestibular system to sound augments BClf hearing thresholds in deaf patients. The sensation of the sound at low frequencies may be present in patients with total deafness and normal vestibular function (predominantly saccule). This improvement disappears when saccular function is lost. PMID:24729901

Full Text Available Aims: To study the efficacy of mometasone furoate monohydrate topical nasal spray in the treatment of otitis media with effusion (OME in children aged between 4 and 15 years. Thus, by comparative analysis of results, at 0 and 6 weeks of using mometasone nasal spray, its efficacy in improving the clinical and audiological status of children with OME is assessed. Materials and Methods: A prospective, clinical study carried out on 22 children aged between 4 and 15 years who had attended our Department of Otolaryngology in a tertiary care hospital from January 2008 to May 2009. Results: The efficacy of mometasone furoate monohydrate topical nasal spray in the resolution of middle ear fluid in children aged between 4 and 15 years with OME in this study group was observed to be significant (52.7%. A significant improvement in the overall symptoms was seen in the treatment group. There was good improvement in the audiological status also. Conclusion: Topical steroids can be an alternative to surgery in controlling OME. However, these results are only short-term; a long-term follow-up is necessary. Topical intranasal mometasone furoate therapy can be considered a good therapeutic option to OME. Nasal administration of this steroid is safe, reproducible, easily performed, and well tolerated by pediatric patients.
This overview study provides information on important phoniatric and audiological aspects of early childhood hearing and language development with the aim of presenting diagnostic and therapeutic approaches. The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA). The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV) infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant for hearing and language development and therefore requires treatment. The third topic covered in this article is speech and language development in the first 3 years of life, which is known today to be crucial for later language development and learning to read and write. There is a short overview and introduction to modern terminology, followed by the abnormalities and diagnostics of early speech and language development. Only some aspects of early hearing and language development are addressed here. Important areas such as the indication for a cochlear implant in the first year of life or because of unilateral deafness are not included due to their complexity. PMID:25587365

Conclusion A cochlear re-implantation procedure is undesirable; however, the cochlear implant surgeon may have to perform a re-implantation procedure occasionally for various reasons. Following standard techniques, implant performance comparable with primary implantation may be achieved. Objective To study the causes and outcomes of cochlear re-implantation in an Asian Indian population. Study design Retrospective analysis of clinical charts over an 18-year period with prospective follow-up of patients. Methods The charts of 534 patients, who underwent cochlear implant, at an Otorhinolaryngology institutional Centre, from January 1997 to January 2015 were studied. Of these, the charts of 18 patients who underwent cochlear re-implantation were studied. The causes and audiological and speech outcomes were analysed. Results Eighteen patients (3.4%) underwent cochlear re-implantation for various reasons. The commonest indication was device failure in seven patients (39%), followed by electrode extrusion in five (28%), trauma in three (11%), electrode migration in two (11%) and improper electrode placement in one (6%) patient. The audiological performance tests and speech tests either remained the same or improved from those achieved for patients undergoing primary implantation, in 87% patients. PMID:26898701
Full Text Available With the geriatric population being the fastest growing segment of our society the number of elderly people with different levels of hearing impairments is increasing. According to the German Society of Hearing Impaired there are concerned 37% of the 60-69-year-old and 54% of the over 70-year-old. Furthermore the needs of the elderly are changing with augmented social activity and agility compared to former times: 80 is the new 70. After initial concerns about poor audiologic performance and added peri- and postoperative risks because of comorbidities, cochlear implantation is becoming more and more the method of choice also for postlingually deaf people of higher age. With the demographic shift there can be observed a trend reversal: the proportion of implantees is sliding from the young to the senior and duration of deafness at the time of implantation is declining (Battmer 2010. It is therefore necessary to investigate the impact of cochlear implantation on audiologic performance and quality of life in this growing age group.

SUMMARY The latest international guidelines highlight the importance of involving the family in the diagnositic and rehabilitation process of children affected by permanent hearing impairment. This emphasises how meaningful this approach is for the development of the deaf child. So far, there is very little evidence about this approach in Italy, and there are still some barriers to its practical management. The aim of this paper is to report the results of a strategic analysis, which identifies the strengths, weaknesses, opportunities and threats of the family empowerment process during early auditory diagnosis and rehabilitation. The audiology programme should have the goal to offer information and support to families in order to achieve a conscious decision about the use and type of auditory prosthesis and rehabilitation choice within three months after audiologic diagnosis. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", a group of professionals identified three main recommendations that can be useful to foster the natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family. The recommendations obtained with this analysis can help to develop new Italian guidelines with the aim to foster natural communicative development of the child by strengthening the therapeutic alliance and empowerment of the family.

Three groups of postlingually deaf adults were formed by non-random selection. The subjects with some residual hearing were fitted with a powerful hearing aid (HA group, n = 10). The others received either a single-channel vibrotactile aid (V group, n = 8) or a single-channel intracochlear implant (CI group, n = 10). Training containing individual counselling and rehearsal in small groups was arranged. During the follow-up (CI group 2.0 yrs, V group 1.8 yrs, HA group 2.6 yrs), the subject's achievement was assessed by a repetition of audiological testing and written questionnaires. Whereas the HA group obtained the highest scores in the audiological tests, the CI group found the implant most beneficial in everyday life. No significant improvement in the test scores was observed during the follow-up. The extent of personal training, after an initial training period and motivation of the user, did not affect the test scores or the subjective evaluation. PMID:2371535

Turner syndrome (TS) is one of the most frequently encountered sex-linked chromosomal abnormalities, occurring in one per 2,000 female births. These patients present with short stature and failure to begin puberty. In this syndrome, there are multiple organ abnormalities, including auditory disorders. TS patients were referred to the ENT clinic by a pediatric endocrinologist. A questionnaire was filled out and the patients went through a complete otologic examination. They were then referred to the audiology clinic to undergo audiologic test battery plus high-frequency pure tone audiometry. From a total of 48 ears examined, 11 (22.9 %) had a normal audiometry. Mid-frequency sensorineural hearing loss (SNHL), high-frequency SNHL, combined and mixed hearing loss were diagnosed in 6 (12/5 %), 20 (41/7 %), 6 (12/5 %) and 1 (2/1 %) ear, respectively. Tympanogram results showed normal compliance (A, As, Ad) in the majority of cases. B and C patterns were found in a few cases. Speech discrimination score was normal in all patients whereas speech reception threshold was normal in 92 % of the ears. Audiometry abnormality especially SNHL is common in TS patients, with the high-frequency pattern being the most frequent. PMID:25534285

This document describes the national protocol for the selection, fitting, verification, and evaluation of amplification for hearing-impaired children in Australia. It also outlines the approach to management of children who have auditory neuropathy spectrum disorder, children who have mild and unilateral hearing loss, and children who require cochlear implantation. Audiological management of all Australian citizens and permanent residents under twenty-one years of age who have a hearing loss is carried out by the national hearing service provider, Australian Hearing. It is funded by the Australian Government's Hearing Services Program to provide fully subsidised hearing aids, frequency modulated (FM) systems and ongoing audiological management. All hearing aids for children are multi-channel devices that offer wide dynamic range compression, directional microphone technology and feedback cancellation as well as access to multiple listening programs, telecoil and audio-input facilities. Hearing aid gain, frequency response and maximum power output are derived according to the NAL-NL1 prescription procedure and verified using real ear measurements. Amplification benefit is evaluated using a range of speech perception tests and functional assessment questionnaires. PMID:19919326

Full Text Available Background and Aim: Hearing loss is one of the most prevalent chronic conditions affecting the elderly. The impacts of hearing loss are depression, social isolation, and functional disability, particularly for those who have not yet been evaluated or treated for hearing loss. The aim of this study was audiologic screening and assessing candidacy for hearing aid in the elderly people.Materials and Methods: This analytic-cross sectional study was performed on 52 older adults aged from 51 to 97. Subjects were evaluated according to ASHA guidelines for audiologic screening in adults (1997. Using HHIE-S as hearing disability screening instrument, the need for hearing aid use was evaluated.Results: About 86 percent of subjects had some degree of hearing loss. There were significant correlation between PTA(0.5, 1, 2 KHz>26 and HHIE-S>10. According to these two factors 21.2 percent of subjects needed to use hearing aid while 18 percent of this group had hearing aids.Conclusion: There is high prevalence of hearing loss among older adults, thus it's necessary to evaluate the need for hearing aid in this rapidly growing population. Among different factors affecting hearing aid candidacy the most correlated were PTA(0.5, 1, 2KHz>26 and HHIE-S>10. Therefore according to this study by combination of these two evaluation of hearing aid candidacy would be more appropriate.

In developing countries there is a lack of trained personnel and testing equipment to facilitate early detection of hearing impairment in children. There is a need to develop a strategic functional model for identification of hearing impairments through a scheme for the optimal utilization of the limited and local resources in the community. A questionnaire offers a low-cost option, specially if it is administered by non-professionals. This study evaluated a parent report questionnaire by non-professionals, to identify hearing loss in pre-school children of a poor community in São Paulo city. Seven volunteers were trained by a professional to use the questionnaire. A total of 133 children aged 3-6 years enrolled in this study. Their parents answered the questionnaire administered by the volunteers and the children underwent audiological screening (audiometry and imitanciometry). The results showed that the volunteers reproduced the evaluation of the professional regarding the use of the questionnaire. The majority of the results were statistically significant and the minimal percentage of concordance was 77%. Of the 133 children who were tested, 12 failed the audiometry screening (9.02%) and 18 failed the tympanometry screening (13.53%). The questionnaire did not differentiate between the children who failed in the audiological screening from those who did not, suggesting further refinements are necessary. PMID:15900189

Introduction The cervical spine is a flexible link between the sensory platform of the skull and torso. The fundamental principle of its operation is due to the balance between muscle strength and flexibility, and any dysfunction of this balance causes neck pain, known as cervicalgia. Objective The objective of this study is to analyze the most prevalent neurotological findings in adults with neck pain. Method A cross-sectional study in which 33 adults from 50 to 83 years of age with neck pain were evaluated and underwent the following procedures: anamnesis, as well as ENT, audiological, and vestibular exams. Results The most evident neurotological symptoms were dizziness (75.7%), tinnitus, neck cracking, tingling in the extremities, and auditory problems (36.3% for each). The most frequently reported clinical symptoms were related to cardiovascular (69.7%), endocrine-metabolic (48.5%), and rheumatic (30.3%) systems. In the audiological assessment, 30 subjects (91.0%) presented hearing impairment in at least one ear, with sensorineural impairment being the most prevalent (88.0%). In the vestibular assessment, there were alterations in 13 subjects (39.0%) found in the caloric test. There was a prevalence of alterations in the peripheral vestibular system with a predominance of irritative peripheral vestibular dysfunction. Conclusion Neurotological complaints were frequent in this population, verifying the importance of these tests in the dysfunctions of the cervical region or the craniocervical junction. PMID:27096014

Full Text Available The objective of this cross-sectional study was to investigate the possibility that the saccule may contribute to human hearing. The forty participants included twenty healthy people and twenty other subjects selected from patients who presented with benign paroxysmal positional vertigo to Audiology Department of Hazrat Rasoul Akram hospital (Tehran, Iran. Assessments comprised of audiological evaluations, cervical vestibular evoked myogenic potentials (cVEMPs, recognition of spoken phonemes in white noise (Rsp in wn, and auditory brainstem response to 500 Hz tone burst (ABR500 HZ. Twenty affected ears with decreased vestibular excitability as detected by abnormal cVEMPs revealed decreased scores of Rsp in wn and abnormal findings of ABR500 HZ. Both unaffected and normal ears had normal results. Multiple comparisons of mean values of cVEMPs and ABR500 HZ between three groups were significant (P<0.05, ANOVA. The correlation between RSP in wn and p13 latencies was significant. The peak-to-peak amplitudes showed significant correlation to RSP in wn. The correlation between RSP in wn and the latencies of n23 was significant. In high-level of noisy competing situations, healthy human saccular sensation can mediate the detection of low frequencies and possibly help in cochlear hearing for frequency and intensity discrimination. So, all human hearing is not cochlear.

Methods: The Self-assessment for Hearing Screening of the Elderly (SHSE consisted of 20 questions based on the characteristics of presbycusis using a five-point scale: seven questions covered general issues related to sensorineural hearing loss, seven covered hearing difficulty under distracting listening conditions, two covered hearing difficulty with fast-rated speech, and four covered the working memory function during communication. To standardize SHSE, 83 elderly participants took part in the study: 25 with normal hearing, and 22, 23, and 13 with mild, moderate, and moderate-to-severe sensorineural hearing loss, respectively, according to their hearing sensitivity. All were retested 3 weeks later using the same questionnaire to confirm its reliability. In addition, validity was assessed using various hearing tests such as a sentence test with background noise, a time-compressed speech test, and a digit span test. Results: SHSE and its subcategories showed good internal consistency. SHSE and its subcategories demonstrated high test–retest reliability. A high correlation was observed between the total scores and pure-tone thresholds, which indicated gradually increased SHSE scores of 42.24%, 55.27%, 66.61%, and 78.15% for normal hearing, mild, moderate, and moderate-to-severe groups, respectively. With regard to construct validity, SHSE showed a high negative correlation with speech perception scores in noise and a moderate negative

The third edition includes an additional chapter on audio-visual interactions and applications, plus more on applications throughout. Reviews of previous editions have characterized it as "an essential source of psychoacoustic knowledge," "a major landmark ," and a book that "without doubt will have a long-lasting effect on the standing and future evolution of this scientific domain."
Full Text Available Chronic inflammation of the middle ear is the most frequent cause of otogenic complications. Meningitis is the most frequent intracranial complications, followed by otogenic brain abscess in neglected otitis media. Although temporal lobe abscesses are more common than cerebellar abscesses, the converse was found to be true in our series of 17 cases. 16 cases of cerebellar abscess and 1 case of temporal lobe abscess were reported as a complication of chronic otitis media (COM. In our group of patients, otogenic brain abscesses were more frequent in male patients of age group 5–20 years with mean age of 14 years. Diagnostic procedure included history, clinical, otorhinolaryngological examination, audiological, microbiological, neurological, ophthalmological, and radiological examinations. The treatment included primary neurosurgical approach (abscess drainage followed by radical otosurgical treatment.

Children diagnosed with autism spectrum disorder (ASD) are often referred for audiological diagnostic evaluation. This article provides some strategies for preparing children for a successful diagnostic evaluation. Children who are deaf or hard of hearing with a dual diagnosis of ASD may have difficulty learning to demonstrate detection or imitation of the Ling 6 sounds. The Ling 6 sounds are used to determine what a child with a dual diagnosis can hear and discriminate with amplification (hearing aids or cochlear implants). Because children with ASD may not look at the conversational partner and may have difficulty with imitation, adaptive strategies may be necessary to teach these children with dual diagnosis their first words. Strategies for teaching children with dual diagnosis through sign language will also be discussed. PMID:25321856
Full Text Available Objectives: The aim of this study was to characterize tinnitus in affected patients. Methods: A retrospective review of medical records from 470 consecutive patients who visited a tertiary care hospital for evaluation of chronic subjective tinnitus between January 2009 and June 2010 was performed. Patients were divided into three subgroups based on age. Clinical, audiological, and psychological characteristics of each subgroup were analyzed. Results: Of the 470 patients evaluated, 85 were less than 40, 217 between 40 and 60, and 168 above 60 years of age. Most patients were men and complained of unilateral, acute high-pitched tinnitus. Most patients above the age of 40 years complained of loud and annoying tinnitus and had worse stress and severity scores. Conclusions: Chronic tinnitus in older adults is subjectively louder, more annoying, and more distressing than that found in younger patients. We recommend considering age in the patient management plan.

Full Text Available According to the Veterans Benefits Administration, more than 672,000 Veterans were service-connected for hearing loss and more than 744,000 Veterans were service-connected for tinnitus as of fiscal year 2010 . Hearing loss and tinnitus are the most prevalent disabilities experienced by Veterans who served during peacetime, Operation Iraqi Freedom/Operation Enduring Freedom, World War II, and the Korean war. In fiscal year 2010, the Department of Veterans Affairs (VA provided 561,212 hearing aids at an estimated cost of $196.7 million and audiological services to Veterans at a cost of $227.4 million.1 Therefore, hearing loss and tinnitus prevention should be a priority for the VA. At least one type of hearing loss—noise-induced hearing loss (NIHL—can be prevented if appropriate protective strategies are implemented.

Full Text Available Along with the inspection of acoustical cortex and brainstem EP in neurologic, otoneurologic and audiologic practice recently start to use so-called vestibular evoked myogenic potentials (VEMP. It is shown, that at ear stimulation by a loud sound and record of sterno-cleidomastoid contraction is possible to estimate function of the inferior vestibular nerve and vestibulospinal pathways, a sacculo-cervical reflex. In article some methodical and clinical questions of application of these kinds are presented. Combine research acoustic brainstem EP and VEMP allows to confirm effectively lesions of acoustical and vestibular ways at brainstem. The conclusion becomes, that this kind of inspection is important for revealing demielinisation and defeats in vestibulospinal tract, that quite often happens at MS, and at estimation of efficiency of treatment

Congenital Permanent Childhood Hearing Impairment (PCHI) is known to have a negative effect on language acquisition, cognitive development and social integration. Since 2000 our department has implemented a UNHS program in the West of Ireland. We describe our experience and detail our results to date. All neonates born from October 2000 to November 2007 were screened using a 2-stage protocol. Transient evoked oto-acoustic emissions (TEOAEs) were used to screen all neonates, followed by automated auditory brainstem response (AABR) in those who did not pass TEOAE, and all neonates at audiological risk. 26,281 babies were born over the eight year period. 25,742 underwent the screening process, achieving a coverage rate of 98%. The prevalence of PCHI in the population tested was 1.21\\/1000 live births (31\\/25,731). Our results show that a hospital based 2-stage UNHS protocol using TEOAEs and AABR is accurate, feasible and effective.

Measurements of middle ear (ME) acoustic power flow (power reflectance, power absorption, and transmittance) and normalized impedance (acoustic resistance, acoustic reactance, and impedance magnitude) were compared for their utility in clinical applications. Transmittance, a measure of the acoustic power absorbed by the ME, was found to have several important advantages over other measures of acoustic power flow. In addition to its simple and audiologically relevant physical interpretation (absorbed power), the normal transmittance curve has a simple shape that is visually similar to the ME transfer function. The acoustic impedance measures (resistance and reactance) provided important additional information about ME status and supplemented transmittance measurements. Together these measurements can help identify unusual conditions such as eardrum perforations. While this article is largely a review of the development of a commercial power reflectance measurement system, previously unpublished experimental results are presented. PMID:16470465
Full Text Available Infections of central nervous system are still a major problem. Despite the introduction of newer antimicrobial agents, mortality and long-term sequelace associated with these infections is unacceptably high. Based on the evidence that proinflammtory cytokines have a role in pathophysiology of bacterial and tuberculous meningitis, corticosteroids with a potent anti-inflammatory and immunomodulating effect have been tested and found to be of use in experimental and clinical studies, Review of the available literature suggests steroid administration just prior to antimicrobial therapy is effective in decreasing audiologic and neurologic sequelae in childern with H. influenzae nenigitis. Steroid use for bacterial meningitis in adults is found to be beneficial in case of S. pneumoniae. The value of adjunctive steroid therapy for other bacterial causes of meningitis remains unproven. Corticocorticoids are found to be of no benefit in viral meningitis, Role of steroids in HIV positive patients needs to be studied.

Verification that Hearing Aids (HA) have been fitted correctly in pre-lingual infants and hard-to-test adults is an important emerging application in technical audiology. These test subjects are unable to undergo reliable behavioral testing, so an objective method is required. Auditory steady-state...... responses (ASSR), recorded in a sound field is a promising technology to verify the hearing aid fitting. The test involves the presentation of the auditory stimuli via a loudspeaker, unlike the usual procedure of delivering via insert earphones. Room reverberation clearly may significantly affect the...... features of the stimulus important for eliciting a strong electrophysiological response, and thus complicate its detection. This study investigates the effect of different room acoustic conditions on recorded ASSRs via an auralisation approach using insert earphones. Fifteen normal-hearing listeners were...

Six profoundly deaf patients were studied with mapping evoked potentials (MEP) using an acoustic signal passed through the vibrotactile prosthesis. This stimulus produced an activation of the central sulcus brain cortex. When the proSthesis was placed in the presenternal area it showed N1 P1 potentials with higher voltage and a more defined cortical dipole inversion than when the prosthesis was placed in the arm or abdomen: thus the presternal stimulation is considered an adequate place for the use of vibrotactile stimulation. The MEP were recorded in 2 patients after a period of audiological training and they showed new earlier potentials.

Three groups of postlingually deaf adults were selected, trained and followed for about 2 years. The subjects with residual hearing were fitted with a powerful hearing aid (HA group, N = 10), the rest were given a single channel vibrotactile aid (V group, N = 8) or received a single channel cochlear implant (CI group, N = 10). The subjects were asked to evaluate the subjective benefit, disadvantage and magnitude of hearing impairment after the rehabilitation. Although the HA group achieved the highest scores in the audiological tests, the interviews revealed that the CI group found the implant quite beneficial in everyday life and in changing their attitude towards the handicap. After 2 years of use, this group reported the highest index of benefit, the best discrimination of everyday sounds and used the device most frequently. The V group were not as satisfied with their devices as the CI and HA groups. PMID:2364187

Tinnitus is one of the most common symptoms in an audiologic field. It can be classified as either as subjective or objective; former referring to the sensation heard by both patient and examiner. Pulsatile tinnitus is perceived as sounds that vary in frequency, intensity and duration. The cause of pulsatile tinnitus include high jugular bulb, benign intracranial hypertension, glomus tumors, carotid artery stenosis, vascular lesions of the temporal bone, arteriovenous malformation, aneurysms, and Arnold-Chiari malformation. Vascular tinnitus is most common (7.6%). Recently, the authors experienced one case of the pulsatile tinnitus caused by atherosclerosis and atheroma in superior labial artery & facial artery. After surgery, the symptom had disappeared. We report a unique case regarding the objective tinnitus with the literature review. PMID:24653894

We present a parallel algorithm that solves a time-domain non-linear mathematical model of the cochlea. The previously known serial solution of the cochlear model is based on LU decomposition in the longitudinal dimension and is iterative in the time dimension. These two characteristics of the serial solution limit parallelism and prevent efficient computations on a massively parallel processor. We introduce a novel parallel algorithm that successfully overcomes the challenges posed by the cochlear model. We present performance results of a parallel implementation of the algorithm that shortens the computation time by a typical factor of 160-180, which makes the proposed algorithm of practical value for applications such as clinical audiological diagnosis.

Full Text Available Objectives: The present study was aimed to investigate age related changes on Caloric test, Gaze Test and Vestibular Evoked Myogenic Potential (cVEMP. Materials and Methods: The participants included 50 individuals ranging from 20-70 years having no complaint of dizziness or any major illness. The basic audiological test battery was carried out followed by Caloric test, Gaze Test and the VEMP. Results: There was no consistent pattern seen on the caloric test and gaze test with advancing age while VEMP showed significant increase in latency and decrease in amplitude of both P13 and N23 as the age advances. Discussion: The comparison of the mean SPV values do not show an age related pattern because the caloric test does not challenge the semicircular canal system enough so as to reveal its defects. The age related changes in the cVEMP parameters could be attributed to the age related degeneration in the vestibular sense organ

It results from air entering the inner ear when a communication between the air-filled middle ear spaces and inner ear is established. The imaging modality of choice for pneumolabyrinth is high-resolution computed tomography of the temporal bone. Treatment options include conservative management (bed rest, antibiotics, corticosteroids or surgery (exploratory tympanotomy. We present the case of a 31-year-old female who had pneumolabyrinth secondary to a temporal bone fracture. The patient was treated surgically and made a full clinical recovery.

This case report demonstrates a case of 5-year-old non-syndromic Malay boy who passed the hearing screening test however he was confirmed has bilateral profound sensorineural hearing loss diagnosed at 3 months of age by brain stem evoked response (BSER). He has background history of severe neonatal jaundice and male siblings of hearing impairment. The antenatal and birth history was uneventful apart from maternal hypothyroidism. His other two elder brothers have bilateral sensorineural hearing loss and history of severe neonatal jaundice as well. The ear examinations, computed tomography scan and magnetic resonance imaging revealed normal findings. Right sided cochlear implantation was done at the age of 3 years old and he is still under audiology follow-up. Conclusion: Genetic studies are important to determine the cause of genetic mutation in susceptibility to hearing impairment that run in his family after severe neonatal jaundice. Those baby with risk of developing hearing loss required diagnostic hearing assessment. (author)
In the past, no definitive diagnostic study was available to assess causes of sudden-onset hearing loss and vertigo. Our observations have led to an interesting new finding: labyrinthine enhancement on Gd-enhanced MR imaging in four patients with sudden unilateral hearing loss and/or vertigo. MR findings were correlated with audiologic and vestibular studies. All patients were studied with T2-weighted axial images through the whole brain and with Gd-DTPA-enhanced, 3-mm, axial, T1-weighted images through the temporal bone. No labyrinthine enhancement was seen in 20 control patients referred for other clinical problems. Gd-MR imaging might be able to distinguish patients with retrocochlear lesions from those in whom the abnormal process is in the labyrinth or is intraaxial

We began our program in September 1992, using the Nucleus 22 Channel Cochlear Implant. To date, we have operated on four patients, one child with congenital hearing loss, two prelinguistically deaf adults and one perilingually deaf adult. Our results have shown a significant increase in auditory and speech reception and perception skills in the child. The perilingually deaf adult is able to understand speech in open set speech discrimination testing and, although we do not expect open set speech discrimination in the prelinguistically deaf adults, to date their results have been satisfactory. The two prelingually deaf adults are in an audiological rehabilitation program. Their response in prosodic aspects of speech and lipreading ability with sound have improved significantly. The only surgical complication was an infection of the flap in the child, but it was treated satisfactorily with i.v. penicillin. PMID:8205978
Using Linden's functional scheme as a theoretical reference framework, we define a matrix of component for clinical and field applications in the acoustic diagnostic process and correlations with audiologic, learning and behavioral problems. It is expected that the model effectively contributes to classify and provide a greater knowledge about this multidisciplinary problem. Although the exact nature of this component is at present a matter to be defined, its correlation can be hypothetically established. Applying this descriptive and integral approach in the diagnostic process it is possible if not to avoid, at least to decrease, the uncertainties and assure the proper solutions becoming a powerful tool applicable to environmental studies and/or social claims.

The sound pressure levels (SPLs) of common infant humidifiers were determined to identify the likely sound exposure to infants and young children. This primary investigative research study was completed at a tertiary-level academic medical center otolaryngology and audiology laboratory. Five commercially available humidifiers were obtained from brick-and-mortar infant supply stores. Sound levels were measured at 20-, 100-, and 150-cm distances at all available humidifier settings. Two of 5 (40%) humidifiers tested had SPL readings greater than the recommended hospital infant nursery levels (50 dB) at distances up to 100 cm. In this preliminary study, it was demonstrated that humidifiers marketed for infant nurseries may produce appreciably high decibel levels. Further characterization of the effect of humidifier design on SPLs and further elucidation of ambient sound levels associated with hearing risk are necessary before definitive conclusions and recommendations can be made.

Full Text Available Tumors originating from ceruminous glands are rare lesions of the external auditory canal. The lack of specific clinical and radiological signs makes their diagnosis challenging. We report the case of an exceptionally rare benign tumor, a syringocystadenoma papilliferum (SCAP, in an atypical location in the bony segment of the external auditory canal with uncommon clinical signs. The special traits of the case included the following: the most lateral component of the tumor was macroscopically cystic and a granular myringitis with an obstructing keratin mass plug was observed behind the mass. The clinical, audiological, radiological, and histological characteristics of the neoplasm are consequently presented. Intraoperative diagnosis of the epidermal cyst was proposed. The final diagnosis of SCAP was determined only by histological analysis after the surgical excision. The educational aspects of the case are critically discussed.

Full Text Available Vertigo is one of the most common symptoms nowadays and its diagnosis is based on the patient’s clinical history and on the otoneurological exam. This study aimed at analyzing the vestibular dysfunction diagnosis efficacy by using only cold caloric irrigation in vectoeletronistagmography. A retrospective survey of 174 vectoeletronistagmography exams from patients of the Audiology sector of Nucleo de Atenção Médica Integrada (NAMI in the University of Fortaleza was done, by comparing the results with two and four irrigations. From the analysed exams, 64 (36,78 % were symmetrical only with the single caloric irrigation (cold water and 110 (63,22 % were not. This kind of procedure is not efficient for the diagnosis, but it can be useful for screening, although a new study is necessary for validation
Full Text Available The estimated hearing ability of German citizens is based on a comprehensive study published by von Stackelberg in 1986. At that time, 26.8% of West-Germany citizens were rated as hearing impaired. Because of the analyzing procedure used, these data cannot be used for comparison purposes with more recent international studies carried out e.g. by Uimonen et al. (1999, Wilson et al. (1999, Quaranta et al. (1996, and Johansson and Arlinger (2003. Other German data are based on non-representative evaluations or on subjective assessments. Therefore, the Institute of Hearing Technology and Audiology started HÖRSTAT, a two-year research project designed to fill this gap.
Full Text Available Background: Diabetes mellitus (DM is commonly metabolic disorders of carbohydrate in which blood glucose levels are abnormally high due to relative or absolute insulin deficiency. In addition, it is characterized by abnormal metabolism of fat, protein resulting from insulin deficit or insulin action, or both. There are two broad categories of DM are designated as type 1 and type 2. Type 2 diabetes is due to predominantly insulin resistance with relative insulin deficiency noninsulin-dependent DM. Type 2 diabetes is much more common than insulin-dependent DM. Objectives: The aim of this study was to assess, if there is any abnormality in neural conduction in auditory brain-stem pathway in type 2 DM patients having normal hearing sensitivity when compared to age-matched healthy populations. Materials and Methods: This study included middle - aged 25 subjects having normal hearing with diabetes type 2 mellitus. All were submitted to the full audiological history taking, otological examination, basic audiological evaluation and auditory brain-stem response audiometry which was recorded in both ears, followed by calculation of the absolute latencies of wave I, III and V, as well as interpeak latencies I-III, III-V, I-V. Results: Type 2 DM patients showed significant prolonged absolute latencies of I, III (P = 0.001 and interpeak latencies I-III, III-V and I-V in left ear (P = 0.001 and absolute latencies of I, V (P = 0.001, interpeak latencies III-V was statistically significant in right ear. Conclusions: The prolonged absolute latencies and interpeak latencies suggests abnormal neural firing synchronization or in the transmission in the auditory pathways in normal hearing type 2 diabetes mellitus patients.
Full Text Available [english] This overview study provides information on important phoniatric and audiological aspects of early childhood hearing and language development with the aim of presenting diagnostic and therapeutic approaches.The article first addresses the universal newborn hearing screening that has been implemented in Germany for all infants since January 2009. The process of newborn hearing screening from the maternity ward to confirmation diagnostics is presented in accordance with a decision by the Federal Joint Committee (G-BA.The second topic is pediatric audiology diagnostics. Following confirmation of a permanent early childhood hearing disorder, the search for the cause plays an important role. Hereditary hearing disorders and intrauterine cytomegalovirus (CMV infection, probably the most common cause of an acquired hearing disorder, are discussed and compared with the most common temporary hearing disorder, otitis media with effusion, which in some cases is severe enough to be relevant for hearing and language development and therefore requires treatment.The third topic covered in this article is speech and language development in the first 3 years of life, which is known today to be crucial for later language development and learning to read and write. There is a short overview and introduction to modern terminology, followed by the abnormalities and diagnostics of early speech and language development.Only some aspects of early hearing and language development are addressed here. Important areas such as the indication for a cochlear implant in the first year of life or because of unilateral deafness are not included due to their complexity.

Reliable methods of reconstruction of the ossicular chain in the situation of an isolated errosion of the long process of the incus using a tympanoplasty type II have not been available until recently. Instead, the tympanoplasty type III has been generally performed with the interposition of an autologous incus. In this presentation, we are describing two methods for reconstruction of the ossicular chain between the in-situ residing incus and the stapes on the other side so that the direct connection eventually will result in a tympanoplasty type II. In the first case, we used ionomeric cement in a way that features two characteristics: the direct connection between the stapes and the long process of the incus could be achieved as well as an articulation that was created on the head of the stapes. Hence, a too stiff connection between the head of the stapes and the long process of the incus could be avoided. In addition, a new method for precise microapplication of cooled bone cement (IONOCAP LV) with a syringe will be presented. In the second method titanium-gold-angle prostheses have been crimped to the long process of the incus and positioned onto the head of the stapes in the way of an articulation. So far, comparison of the audiological results of those two methods of a tympanoplasty type II reveal in average better results than postoperative conductive hearing thresholds of the conventional tympanoplasty type III. If the achieved results can be reproduced on a larger number of patients, the expected audiological results are likely to resemble those of stapes surgery. PMID:9417436
Full Text Available Introduction. Etiopathogenetically, there are two types of chollesteatomas: congenital, and acquired. Numerous theories in the literature try to explain the nature of the disease, however, the question about cholesteatomas remain still unanswered. The aim of the study was to present a case of external ear canal cholesteatoma (EEC developed following microsurgery (ventilation tube insertion and mastoidectomy, as well as to point ant possible mechanisms if its development. Case report. A 16-yearold boy presented a 4-month sense of fullness in the ear and otalgia on the left side. A year before, mastoidectomy and posterior atticotomy were performed with ventilation tube placement due to acute purulent mastoiditis. Diagnosis was based on otoscopy examination, audiology and computed tomography (CT findings. CT showed an obliterative soft-tissue mass completely filled the external ear canal with associated erosion of subjacent the bone. There were squamous epithelial links between the canal cholesteatoma and lateral tympanic membrane surface. They originated from the margins of tympanic membrane incision made for a ventilation tube (VT insertion. The position of VT was good as well as the aeration of the middle ear cavity. The tympanic membrane was intact and of normal appearance without middle ear extension or mastoid involvement of cholesteatoma. Cholesteatoma and ventilation tube were both removed. The patient recovered without complications and shortly audiology revealed hearing improving. Follow-up 2 years later, however, showed no signs of the disease. Conclusion. There could be more than one potential delicate mechanism of developing EEC in the ear with VT insertion and mastoidectomy. It is necessary to perform routine otologic surveillance in all patients with tubes. Affected ear CT scan is very helpful in showing the extent of cholesteatoma and bony defects, which could not be assessed by otoscopic examination alone.

Full Text Available Introduction: The vascular compression by redundant vessels under the VIII cranial nerves has been studied since the 80's, and many authors proposed correlations between the compression and the otoneurological findings (vertigo, tinnitus, hypoacusis, audiometry and electrophysiological findings. Objective: Analyze and correlate the different signs and otoneurological symptoms, the audiological findings and its incidence over individuals with Vascular Loop (VL diagnosis of VIII cranial nerves by magnetic resonance imaging (MRI. Method: Retrospective study through the analysis of medical records of 47 patients attended in the otoneurology clinic of Clinical Hospital of UFPR. All the patients have MRI exams with compatible pictures of VL of the VIII cranial nerves. Results: The tinnitus was the most frequent symptom, in 83% of the patients, followed by hypoacusis (60% and vertigo (36%. The audiometry presented alterations in 89%, the brainstem evoked auditory potential in 33% and the vecto-electronystagmography in 17% of the patients. Was not found statistically significant relation between the buzz or hypoacusis, and the presence of VL in MRI. Only 36% of patients had complaints of vertigo, the main symptom described in theory of vascular compression of the VIII pair of nerve. As in the audiometry and in brainstem evoked auditory potential was not found a statistically significant relation between the exam and the presence of the VL in the RMI. Conclusion: The results show independence between the findings of the RMI, clinical picture and audiological results (p>0,05 suggesting that there are no exclusive and direct relation between the diagnosis of vascular loop in the MRI and the clinical picture matching.
Full Text Available Abstract Background When evaluating hearing rehabilitation, it is reasonable to use self-report questionnaires as outcome measure. Questionnaires used in audiological research are developed and validated for the paper-and-pencil format. As computer and Internet use is increasing, standardized questionnaires used in the audiological context should be evaluated to determine the viability of the online administration format. The aim of this study was to compare administration of questionnaires online versus paper- and pencil of four standardised questionnaires used in hearing research and clinic. We included the Hearing Handicap Inventory for the Elderly (HHIE, the International Outcome Inventory for Hearing Aids (IOI-HA, Satisfaction with Amplification in Daily Life (SADL, and the Hospital Anxiety and Depression Scale (HADS. Methods A cross-over design was used by randomly letting the participants complete the questionnaires either online or on paper. After 3 weeks the participants filled out the same questionnaires again but in the other format. A total of 65 hearing-aid users were recruited from a hearing clinic to participate on a voluntary basis and of these 53 completed both versions of the questionnaires. Results A significant main effect of format was found on the HHIE (p Conclusions For three of the four included questionnaires the participants’ scores remained consistent across administrations and formats. For the fourth included questionnaire (HHIE a significant difference of format with a small effect size was found. The relevance of the difference in scores between the formats depends on which context the questionnaire is used in. On balance, it is recommended that the administration format remain stable across assessment points.

We also compared these results to explore the cross-cultural differences and similarities among these countries. Methods: The study involved a cross-sectional design, and the data were collected from four different countries using the snowball sampling method. Data were analyzed using a content analysis to identify the most-similar categories of responses reported, a co-occurrences analysis to see which of these categories are reported commonly, and a chi-square analysis to study if there was any association between positive, neutral, and negative connotations among participants in different countries. Results: The current study revealed four different social representations of hearing aids from India, Iran, Portugal, and the United Kingdom, and also a global index. Conclusion: The study results provide very useful insights into how hearing aids are represented in the society. These findings may have important implications for public education and also for manufacturers from the viewpoint of designing and marketing hearing aids in different countries.

A self-contained, self-fitting hearing aid (SFHA) is a device that enables the user to perform both threshold measurements leading to a prescribed hearing aid setting and fine-tuning, without the need for audiological support or access to other equipment. The SFHA has been proposed as a potential solution to address unmet hearing health care in developing countries and remote locations in the developed world and is considered a means to lower cost and increase uptake of hearing aids in developed countries. This article reviews the status of the SFHA and the evidence for its feasibility and challenges and predicts where it is heading. Devices that can be considered partly or fully self-fitting without audiological support were identified in the direct-to-consumer market. None of these devices are considered self-contained as they require access to other hardware such as a proprietary interface, computer, smartphone, or tablet for manipulation. While there is evidence that self-administered fitting processes can provide valid and reliable results, their success relies on user-friendly device designs and interfaces and easy-to-interpret instructions. Until these issues have been sufficiently addressed, optional assistance with the self-fitting process and on-going use of SFHAs is recommended. Affordability and a sustainable delivery system remain additional challenges for the SFHA in developing countries. Future predictions include a growth in self-fitting products, with most future SFHAs consisting of earpieces that connect wirelessly with a smartphone and providers offering assistance through a telehealth infrastructure, and the integration of SFHAs into the traditional hearing health-care model.

The field of Bioacoustics is an emerging field of science that investigates various aspects of animal audiology and communication. More recently, audiological means have been used to evaluate the cognitive abilities of animals using event related brain potentials (ERP's). The Mismatch Negativity (MMN) component of the ERP is considered a cognitive neuroelectric phenomenon since it is generated in the area of the cortex that is responsible for evaluating sound stimuli including the ability to discriminate. Such discrimination produces a negative-going waveform with a relative latency of about 150-250 msec when elicited with auditory stimuli in human adults. The MMN response is elicited by use of the oddball paradigm in which two different tones are presented in pseudo-random order. The purpose of this study was to determine if elicitation of the MMN is achievable in the horse by use of current equipment in a non-clinical setting such as a barn. During the course of this experiment, it became obvious that the major challenge was the excessive amount of noise that inundated the waveforms thereby making any specific waves even remotely discernible. Attempts were made to improve the signal-to-noise ratio (SNR) by modifications to the testing unit and the addition of several in-line and digital filters. However, even with these modifications, the MMN response still could not be identifiable within the noise of the waveforms. Therefore, the matter of whether or not the horse elicits a MMN response should be revised to if it is even feasible to elicit a MMN response in these animals.

Full Text Available Introduction: The process of education of a patient aims to improve knowledge and skill of the patient and/or family, in a way to influence attitudes and behaviors needed to maintain or improve health. Must be a integral part of interpersonal communication between health professionals and patients, and this can happen through interpersonal communication and various other means such as pamphlets, manuals and, more recently, computer resources. Goal: This update article approach the patient education and the internet potential for this process, still presenting some initiatives in the audiology área. Discussion: The informations, related to health are popular in the internet, and include interactive websites, portals, e-mails, telehealth aplications, and others. The education of the patients supported by the internet can help to solve a big ethical, political and economic issue: the problem to conciliate the needs and the expectations of the patients with the characteristics and limitations of the health system. Although the use of internet in the education of the patient is promising, this is not a solution to be used without careful planning, monitoring and evaluation. In audiology there are few initiatives with the use of e-mails and websites for complement of the patient education. Final Considerations: The health professionals, including the speech therapists, must check if their patients use internet resources, recognize that behavior change and prepare not only to discuss the information obtained with the patient, but also suggest websites with reliable information and help them to evaluate the quality of the information available online.

Full Text Available Background: Although it is not a new disorder, in recent times we have attained a greater understanding of auditory neuropathy (AN. In this type of hearing impairment, cochlear hair cells function but AN victims suffer from disordered neural transmission in the auditory pathway. The auditory neuropathy result profile often occurs as a part of that of the generalized neuropathic disorders, indicated in approximately 30-40% of all reported auditory neuropathy/auditory dyssynchrony (AN/AD cases, with approximately 80% of patients reporting symptom onset over the age of 15 years. In the present report, the results of audiologic tests (behavioral, physiologic and evoked potentials on two young patients with generalized neuropathy are discussed.Case report: Two brothers, 26 and 17 years old, presented with speech perception weakness and movement difficulties that started at 12 years of age and progressed as time passed. In their last examination, there was a moderate to severe flat audiogram in the older patient and mild low tone loss in the younger one. The major difficulty of the patients was severe speech perception impairment that was not compatible with their hearing thresholds. Paresthesia, sural muscle contraction and pain, and balance disorder were the first symptoms of the older brother. Now he can only move with crutches and his finger muscle tonicity has decreased remarkably, with marked fatigue after a short period of walking. Increasing movement difficulties were noted in his last visit. Visual neuropathy had been reported in repeated visual system examinations for the older brother, with similar, albeit less severe, symptoms in the younger brother.In the present study of these patients, behavioral investigations included pure-tone audiometry and speech discrimination scoring. Physiologic studies consisted Transient Evoked Otoacoustic Emission (TEOAE and acoustic reflexes. Electrophysiologic auditory tests were also performed to determine

Full Text Available Algumas drogas, denominadas ototóxicas, têm a capacidade de lesar os sistemas auditivo e vestibular. O avanço tecnológico tem disponibilizado inúmeros recursos para realizar o monitoramento da audição, porém, apesar da disponibilização de protocolos de avaliação internacionais, existem controvérsias quanto à escolha do procedimento de maior sensibilidade e especificidade para este fim. OBJETIVO: Analisar os procedimentos audiológicos utilizados no monitoramento auditivo dos indivíduos expostos à medicação ototóxica. METODOLOGIA: Realizou-se busca eletrônica nas bases de dados MEDLINE e LILACS, a partir da combinação entre os descritores que caracterizaram as temáticas monitoramento auditivo, ototoxicidade e câncer. A literatura apontou dois principais procedimentos efetivos no monitoramento: a audiometria de altas freqüências e as emissões otoacústicas. Ambos permitem que a alteração no sistema auditivo seja identificada antes que haja um comprometimento dos limiares tonais na faixa de freqüências convencional, e conseqüentemente na habilidade de compreensão da fala. CONCLUSÃO: O protocolo de monitoramento auditivo foi sugerido considerando a capacidade do paciente em responder aos testes comportamentais e a etapa do monitoramento (primeira avaliação ou subseqüentes. No caso de portadores de câncer, o monitoramento auditivo deve ser disponibilizado no local de tratamento do indivíduo.Some pharmaceutical products are capable of damaging the human auditory system. Technological progress has provided numerous resources to monitor hearing but there still is some controversy regarding the selection of the most sensitive and specific tests.

Full Text Available Magdalena Lachowska, Agnieszka Pastuszka, Paulina Glinka, Kazimierz Niemczyk Department of Otolaryngology, Hearing Implant Center, Medical University of Warsaw, Warsaw, Poland Purpose: To assess the benefits of cochlear implantation in the elderly. Patients and methods: A retrospective analysis of 31 postlingually deafened elderly (≥60 years of age with unilateral cochlear implants was conducted. Audiological testing included preoperative and postoperative pure-tone audiometry and a monosyllabic word recognition test presented from recorded material in free field. Speech perception tests included Ling's six sound test (sound detection, discrimination, and identification, syllable discrimination, and monosyllabic and multisyllabic word recognition (open set without lip-reading. Everyday life benefits from cochlear implantation were also evaluated. Results: The mean age at the time of cochlear implantation was 72.4 years old. The mean post-implantation follow-up time was 2.34 years. All patients significantly improved their audiological and speech understanding performances. The preoperative mean pure-tone average threshold for 500 Hz, 1,000 Hz, 2,000 Hz, and 4,000 Hz was 110.17 dB HL. Before cochlear implantation, all patients scored 0% on the monosyllabic word recognition test in free field at 70 dB SPL intensity level. The postoperative pure-tone average was 37.14 dB HL (the best mean threshold was 17.50 dB HL, the worst was 58.75 dB HL. After the surgery, mean monosyllabic word recognition reached 47.25%. Speech perception tests showed statistically significant improvement in speech recognition. Conclusion: The results of this study showed that cochlear implantation is indeed a successful treatment for improving speech recognition and offers a great help in everyday life to deafened elderly patients. Therefore, they can be good candidates for cochlear implantation and their age alone should not be a relevant or excluding factor when choosing

The aim of this study was to introduce a new grafting technique in tympanoplasty that involves use of a boomerang-shaped chondroperichondrial graft (BSCPG). The anatomical and functional results were evaluated. A new tympanoplasty with boomerang-shaped chondroperichondrial graft (TwBSCPG) technique was used in 99 chronic otitis media patients with central or marginal perforation of the tympanic membrane and a normal middle ear mucosa. All 99 patients received chondroperichondrial cartilage grafts with a boomerang-shaped cartilage island left at the anterior and inferior parts. Postoperative follow-ups were conducted at months 1, 6, and 12. Preoperative and postoperative audiological examinations were performed and air-bone gaps were calculated according to the pure-tone averages (PTAs) of the patients. In the preoperative period, most (83.8%) air-bone gaps were ≥ 16 dB; after operating using the TwBSCPG technique, the air-bone gaps decreased to 0-10 dB in most patients (77.8%). In the TwBSCPG patients, the mean preoperative air-bone gap was 22.02 ± 6.74 dB SPL. Postoperatively, the mean postoperative air-bone gap was 8.70 ± 5.74 dB SPL. The TwBSCPG technique therefore decreased the postoperative air-bone gap compared to that preoperatively (p = 0.000, z = -8.645). At the 1-month follow-up, there were six graft perforations and one graft retraction. At the 6-month follow-up, there were nine graft perforations and three graft retractions. At 12 months, there were seven graft perforations and four graft retractions. During the first year after the boomerang tympanoplasty surgery, graft lateralization was not detected in any patient. Retractions were grade 1 according to the Sade classification and were localized to the postero-superior quadrant of the tympanic membrane. The TwBSCPG technique has benefits with respect to postoperative anatomical and audiological results. It prevents perforation of the tympanic membrane at the anterior quadrant and avoids graft

Allied health professionals in nutrition and medical dietetics, occupational therapy, physical therapy, and speech-language pathology and audiology play both unique and key cross-cutting roles in the furtherance of clinical research. Clinical research in nutrition and medical dietetics uniquely focuses on food nutrient intake and the metabolic utilization of nutrients. Clinical research in occupational therapy has a special focus on the relationship of impairment to disability, the adaptation to disability and the maximization of function. Physical therapy clinical research uniquely targets movement dysfunction and its evaluation and treatment within the context of quality and effective care. Clinical research in speech-language pathology and audiology is singular in its focus on deafness and hearing disorders, voice, speech, language and related disorders, and intersections among these and other neurological and physical conditions. Thus, all of these disciplines are making unique contributions to clinical research. Clinical research in these allied health professions is much more than the above specific foci. Inasmuch as these disciplines are rooted in practice, their contributions to research are inherently clinical. Many, if not most, of these contributions represent further validations of clinical practice or its underlying knowledge base. This means that, at a macro level, clinical research in allied health is very much "applied" research. Within allied health clinical research, this emphasis is redoubled at the "person," or individual level, where considerable attention is given to concepts of function and effectiveness. Clinical research in allied health has played a key cross-cutting role through its emphasis on collaboration. Possibly due to their professional maturation within multidisciplinary academic units, allied health professionals have demonstrated a level of comfort with multidisciplinary and interdisciplinary collaborations unique within many

In Optometry and in Audiology, the routine tests to prescribe correction lenses and headsets are respectively the visual acuity test (the first chart with letters was developed by Snellen in 1862) and conventional pure tone audiometry (the first audiometer with electrical current was devised by Hartmann in 1878). At present there are psychophysical non invasive tests that, besides evaluating visual and auditory performance globally and even in cases catalogued as normal according to routine tests, supply early information regarding diseases such as diabetes, hypertension, renal failure, cardiovascular problems, etc. Concerning Optometry, one of these tests is the achromatic luminance contrast sensitivity test (introduced by Schade in 1956). Concerning Audiology, one of these tests is high frequency pure tone audiometry (introduced a few decades ago) which yields information relative to pathologies affecting the basal cochlea and complements data resulting from conventional audiometry. These utilities of the contrast sensitivity test and of pure tone audiometry derive from the facts that Fourier components constitute the basis to synthesize stimuli present at the entrance of the visual and auditory systems; that these systems responses depend on frequencies and that the patient's psychophysical state affects frequency processing. The frequency of interest in the former test is the effective spatial frequency (inverse of the angle subtended at the eye by a cycle of a sinusoidal grating and measured in cycles/degree) and, in the latter, the temporal frequency (measured in cycles/sec). Both tests have similar duration and consist in determining the patient's threshold (corresponding to the inverse multiplicative of the contrast or to the inverse additive of the sound intensity level) for each harmonic stimulus present at the system entrance (sinusoidal grating or pure tone sound). In this article the frequencies, standard normality curves and abnormal threshold shifts

Full Text Available Abstract Background Tinnitus affects about 10-15% of the general population and risks for developing tinnitus are rising through increased exposure to leisure noise through listening to personal music players at high volume. The disorder has a considerable heterogeneity and so no single mechanism is likely to explain the presence of tinnitus in all those affected. As such there is no standardized management pathway nor singly effective treatment for the condition. Choice of clinical intervention is a multi-factorial decision based on many factors, including assessment of patient needs and the healthcare context. The present research surveyed clinicians working in six Westernized countries with the aims: a to establish the range of referral pathways, b to evaluate the typical treatment options for categories of subjective tinnitus defined as acute or chronic, and c to seek clinical opinion about levels of satisfaction with current standards of practice. Methods A structured online questionnaire was conducted with 712 physicians who reported seeing at least one tinnitus patients in the previous three months. They were 370 general practitioners (GPs and 365 ear-nose-throat specialists (ENTs from the US, Germany, UK, France, Italy and Spain. Results Our international comparison of health systems for tinnitus revealed that although the characteristics of tinnitus appeared broadly similar across countries, the patient's experience of clinical services differed widely. GPs and ENTs were always involved in referral and management to some degree, but multi-disciplinary teams engaged either neurology (Germany, Italy and Spain or audiology (UK and US professionals. For acute subjective tinnitus, pharmacological prescriptions were common, while audiological and psychological approaches were more typical for chronic subjective tinnitus; with several specific treatment options being highly country specific. All therapy options were associated with low levels

Full Text Available Prolactinomas typically present with oligoamenorrhea or galactorrhea in woman and headaches, visual changes or impotence in men with auditory symptoms being a rare presentation. We describe a case of a man who presented with bilateral hearing loss and was found to have a giant prolactinoma. Initial audiogram indicated an air-bone conduction gap suggesting a mixed sensorineural and conductive hearing loss. Measured prolactin was 3711.0 ng/mL and an a magnetic resonance revealed a 3.0×3.0×3.3 cm heterogeneously enhancing mass arising from the sella turcica compressing the left half of the optic chiasm. Several months after treatment, prolactin was 26 ng/mL and the patient reported marked improvement in his vision with mild improvement of his hearing. Although prolactinomas typically present with classic symptoms, one must be aware of unusual presentations. Further investigation is needed to access the correlation between prolactin and hearing loss, which may impact potential audiology screening for those with elevated prolactin.

From the various capabilities of holography for image processing and measuring purposes, holographic interferometric techniques have found more extended application in biological and medical research. Due to their special properties the different methods of holographic interferometry are applied to characteristic fields of biomedical investigations where--similar to nondestructive testing--vibration and deformation analysis is of interest. Features of holographic interferometry, such as the possibility of noncontactive, three-dimensional investigations with a large field-of-depth, are used with advantage. The main applications can be found in basic research e.g., in audiology, dentistry, opthalmology, and experimental orthopedics. Because of the great number of investigations and the variety of medical domains in which these investigations were performed this survey is confined to some characteristic examples. As in all fields of optics and laser metrology, a review on biomedical applications of holography would be incomplete if military developments and utilization were not mentioned. As demonstrated by selected examples, the increasing interlacing of science with the military does not stop at domains that traditionally are regarded as exclusively oriented to human welfare--like biomedical research. The term ''Star Wars Medicine'', which becomes an increasingly popular expression for laser applications (including holography) in medicine, characterizes the consequences of this development.

The main objective of this study was to assess the associations between self-reported listening habits and perception of music and speech perception outcomes in quiet and noise for both unilateral cochlear implant (CI) users and bimodal (CI in one ear, hearing aid in contra-lateral ear) users. Information concerning music appreciation was gathered by means of a newly developed questionnaire. Moreover, audiological data (pure-tone audiometry, speech tests in noise and quiet) were gathered and the relationship between speech perception and music appreciation is studied. Bimodal users enjoy listening to music more in comparison with unilateral CI users. Also, music training within rehabilitation is still uncommon, while CI recipients believe that music training might be helpful to maximize their potential with current CI technology. Music training should not be exclusively reserved for the good speech performers. Therefore, a music training program (MTP) that consists of different difficulty levels should be developed. Hopefully, early implementation of MTP in rehabilitation programs can enable adult CI users to enjoy and appreciate music and to maximize their potential with commercially available technology. Furthermore, because bimodal users consider the bimodal stimulation to be the most enjoyable way to listen to music, CI users with residual hearing in the contra-lateral ear should be encouraged to continue wearing their hearing aid in that ear.

Full Text Available Portability of equipment is an increasingly important component in the practice of audiology. We report on a new device, the OtoID, that supports evidence-based ototoxicity testing protocols, provides capability for hearing testing on the hospital treatment unit, and can automate patient self-testing. The purpose of this article is to report on the validation and verification of the OtoID portable audiometer in 40 subjects both young and old, with and without hearing impairment. Subjects were evaluated by an audiologist using the manual hearing test program and then self-tested via an automated testing program. Testing was done in a sound booth and on a hospital treatment unit. Therefore, data were collected in four conditions (booth vs hospital unit and automated vs manual testing and analyzed for testing bias, repeatability, and American Speech-Language-Hearing Association-significant ototoxicity false-positive rate. Repeatable hearing threshold results were obtained on all subjects who performed the test, regardless of hearing status or testing location.

The aim of this study was to compare anatomical and audiological results of boomerang-shaped chondroperichondrial graft (BSCPG) with temporal muscle fascia in type 1 tympanoplasties. Sixty-eight patients in BSCPG group and 54 patients in fascia group were evaluated. Otomicroscopic examination was done periodically till 24 months as for graft perforation, lateralization and retraction and mean air conduction threshold and airbone gap values were measured. At long term controls, in BSCPG group, rates of neomembrane, perforation, retraction and lateralization were 91.17 % (n = 62), 8.82 % (n = 6), 4.41 % (n = 3) and 0 % (n = 0), respectively. In fascia group, the corresponding rates were 79.62 % (n = 43), 20.37 % (n = 11), 12.96 % (n = 7) and 3.7 % (n = 2), respectively. In both groups, mean postoperative PTA and ABG values were significantly better while postoperative same values were significantly different between groups (p = 0.044 and 0.032, respectively). Compared to fascia, BSCPG is an ideal grafting technique in the repair of tympanic membrane perforations. PMID:27508137

Fatigue is common in individuals with a variety of chronic health conditions and can have significant negative effects on quality of life. Although limited in scope, recent work suggests persons with hearing loss may be at increased risk for fatigue, in part due to effortful listening that is exacerbated by their hearing impairment. However, the mechanisms responsible for hearing loss-related fatigue, and the efficacy of audiologic interventions for reducing fatigue, remain unclear. To improve our understanding of hearing loss-related fatigue, as a field it is important to develop a common conceptual understanding of this construct. In this article, the broader fatigue literature is reviewed to identify and describe core constructs, consequences, and methods for assessing fatigue and related constructs. Finally, the current knowledge linking hearing loss and fatigue is described and may be summarized as follows: Hearing impairment may increase the risk of subjective fatigue and vigor deficits; adults with hearing loss require more time to recover from fatigue after work and have more work absences; sustained, effortful, listening can be fatiguing; optimal methods for eliciting and measuring fatigue in persons with hearing loss remain unclear and may vary with listening condition; and amplification may minimize decrements in cognitive processing speed during sustained effortful listening. Future research is needed to develop reliable measurement methods to quantify hearing loss-related fatigue, explore factors responsible for modulating fatigue in people with hearing loss, and identify and evaluate potential interventions for reducing hearing loss-related fatigue.

Full Text Available Background. Hearing aids sold directly to consumers in retail stores or through the internet, without individual prescription by audiological professionals, are termed over-the-counter (OTC devices. This study aimed to determine whether there was any change in the electroacoustic characteristics of OTC devices compared to research carried out a decade earlier. The previous results indicated that most OTC devices were low-frequency-emphasis devices and were unsuitable for elderly people with presbycusis, who were likely to be the major consumers of these products. Methods. Ten OTC devices were selected and their electroacoustic performance was measured. Appropriate clients for the OTC devices were derived, using four linear prescription formulae, and OTC suitability for elderly persons with presbycusis was investigated. Results. OTC electroacoustic characteristics were similar to those in the earlier study. Most OTC devices were not acoustically appropriate for potential consumers with presbycusis. Although several of the devices could match prescriptive targets for individuals with presbycusis, their poor electroacoustic performance—including ineffective volume control function, high equivalent input noise, and irregular frequency response—may override their potential benefit. Conclusion. The low-cost OTC devices were generally not suitable for the main consumers of these products, and there has been little improvement in the appropriateness of these devices over the past decade.

Chronic lung disease (CLD) in children represents a heterogeneous group of many clinico-pathological entities with risk of adverse impact of chronic or intermittent hypoxia. So far, few researchers have investigated the cognitive function in these children, and the role of auditory P300 in the assessment of their cognitive function has not been investigated yet. This study was designed to assess the cognitive functions among schoolchildren with different chronic pulmonary diseases using both auditory P300 and Stanford-Binet test. This cross-sectional study included 40 school-aged children who were suffering from chronic chest troubles other than asthma and 30 healthy children of similar age, gender and socioeconomic state as a control group. All subjects were evaluated through clinical examination, radiological evaluation and spirometry. Audiological evaluation included (basic otological examination, pure-tone, speech audiometry and immittancemetry). Cognitive function was assessed by auditory P300 and psychological evaluation using Stanford-Binet test (4th edition). Children with chronic lung diseases had significantly lower anthropometric measures compared to healthy controls. They had statistically significant lower IQ scores and delayed P300 latencies denoting lower cognitive abilities. Cognitive dysfunction correlated to severity of disease. P300 latencies were prolonged among hypoxic patients. Cognitive deficits in children with different chronic lung diseases were best detected using both Stanford-Binet test and auditory P300. P300 is an easy objective tool. P300 is affected early with hypoxia and could alarm subtle cognitive dysfunction. PMID:27075686

Full Text Available Introduction: Organic solvents have been increasingly studied due to its ototoxic action. Objective: Evaluate the conditions of outer hair cells and olivocochlear system in individuals exposed to organic solvents. Method: This is a prospective study. 78 gas station attendants exposed to organic solvents had been evaluated from three gas stations from Santa Maria city, Rio Grande do Sul (RS. After applying the inclusion criteria, the sample was constituted by 24 individuals. The procedures used on the evaluation were audiological anamnesis, Transient otoacoustic emissions (TEOAES and research for the suppressive effect of TEOAES. A group control (GC compounded by 23 individuals was compared to individuals exposed and non-exposed individuals. The data collection has been done in the room of Speech Therapy of Workers Health Reference Center of Santa Maria. Results: The TEOAES presence was major in the left ear in both groups; the average relation of TEOAES signal/noise in both ears was greater in GE; the TEOAES suppressive effect in the right ear was higher in the individual of GE (62,5% and in the left ear was superior in GC (86,96%, with statistically significant difference. The median sign/noise ratio of TEOAES, according to the frequency range, it was higher in GC in three frequencies ranges in the right ear and one in the left ear. Conclusion: It was not found signs of alteration on the outer hair cells neither on the olivocochlear medial system in the individuals exposed to organic solvents.

Introduction. Rheumatoid arthritis (RA) can involve the incudomalleolar or incudostapedial articulations. Objective. To know the punctual prevalence of audiological alterations in patients with RA. Patients and Methods. RA patients and their controls (Cs), were evaluated by Tonal Audiometry (AU); if there were alterations in the air conduction (AC), bone conduction (BC), Logoaudiometry (LG), and Tympanometry (T) were performed. Results. 45 RA patients and 45 Cs were evaluated. RA patients had 40% of bilateral and 17.8% unilateral alteration versus Cs with 22.2% bilateral and 4.4% unilateral alteration versus Cs with 22.2% bilateral and 4.4% unilateral in AC audiometry. In conventional T (CT) As-type curves in patients with RA, there were 22 LE (48.8%) and 26 RE (57.7%) versus Cs, there were16 RE (35.5%) and 20 LE (44.4%). In High-frequency T (HFT): the 3B1G pattern in RA more frequent versus Controls (Cs) in RE (P = .002 and LE (P = .01). There were no differences according to RA activity or RA disease evolution. Conclusions. There is a greater tendency of auditive loss of As curves in CT (rigidity in ossicular chain) and of the 3B1G pattern in HFT in RA. PMID:22482066
Full Text Available Introduction: Universal newborn hearing screening (UNHS is mandatory in all developed country and is setting the trend in developing country too. Due to a large population, lack of education, less professionals, and limited access to such facilities in India few places targeted hearing screening (THS is coming up. However, the comparison between UNHS and THS is less investigated till date. Aim of the Study: This study aimed to investigate the comparison between two hearing screening program that is UNHS and THS in the Indian context. Methods: In UNHS all the infants were screened at Tertiary Centre and for THS only infant with high-risk factors were screened at Advanced Audiological Centre. Further, all referral, screening, and diagnostic data were included in data analysis of both hearing screening program. Result: UNHS was difficult due to some system failure and a lot of time was wasted doing the different procedure. However, THS was much easier and false-positive and negative were lesser. Conclusion: In a vast population country with lack of manpower for the fi eld, it is important to have an alternative approach to the system for better outcome of the program.

Results are presented from a study of the prevalence of middle and external ear disorders in coal miners who work underground. The study followed from an earlier NIOSH report (1976) that indicated a possibly large number of otoscopic abnormalities in this population of workers. Otoscopic examinations, pure tone air- and bone-conduction audiometry tests, and impedance tests were administered to 350 underground miners and 150 industrial workers not associated with mining. The study was conducted completely within a hospital otolaryngology/audiology clinic setting. Results of the investigation showed a highly similar prevalence of middle ear and ear canal abnormalities in the miner group and the control group (19 percent). Middle ear abnormalities observed in the miners were judged by the examining otolaryngologists to have preceded their experience in the mines and were not related solely to underground noise exposure or coal dust. Nearly half of the subjects who had an air-bone gap had no middle ear abnormality observable by otoscopic examination. There was substantial agreement between the finding of abnormal otoscopy and abnormal tympanometry. By itself, acoustic reflex was not useful in identifying middle ear disorders, since this reflex may be absent for other reasons, including presence of severe sensorineural hearing loss.

Full Text Available Aims: To analyze and compare the outcomes of ossiculoplasty in terms of hearing results and graft take-up rates, using autograft incus and titanium middle ear prosthesis in patients with ossicular chain erosion. Study Design: Randomized clinical trial. Materials and Methods: Patients between 10 and 60 years of age with a history of chronic ear discharge with moderate conductive deafness (>40 dB HL were included in the study. The patients underwent detailed ENT examination followed by audiological and radiological assessment of temporal bone and those patients with evidence of ossicular erosion were subjected to ossiculoplasty with autologous incus (group I or titanium prosthesis (group II randomly. The patients were followed up after 3 months to analyze the functional and anatomical results. Results: A total of 24 patients with ossicular chain defect were included in the study, of whom 12 patients underwent ossiculoplasty with autograft incus and 12 with titanium prosthesis. Postoperative hearing evaluation by pure tone audiogram was done after 3 months, which showed successful hearing improvement in 58% of cases with autologous incus as compared to 33% cases with titanium prosthesis. Complications and extrusion rate were also higher in patients with titanium prosthesis. Conclusion: Hearing results after ossiculoplasty with autologous incus were significantly better compared with those after titanium prosthesis. Also, complications and extrusion rate were higher in patients with titanium prosthesis. This indicates that ossiculoplasty with autoincus offers better hearing results with minimal complications and extrusion rates as compared to titanium prosthesis.

Full Text Available This study examined the relationship between hearing levels, otoacoustic emission levels and listening habits related to the use of personal listening devices (PLDs in adults with varying health-related fitness. Duration of PLD use was estimated and volume level was directly measured. Biomarkers of health-related fitness were co-factored into the analyses. 115 subjects ages 18–84 participated in this study. Subjects were divided into two sub-groups; PLD users and non-PLD users. Both groups completed audiological and health-related fitness tests. Due to the mismatch in the mean age of the PLD user versus the non-PLD user groups, age-adjusted statistics were performed to determine factors that contributed to hearing levels. Age was the most significant predictor of hearing levels across listening and health-related fitness variables. PLD user status did not impact hearing measures, yet PLD users who listened less than 8 hours per week with intensities of less than 80 dBA were found to have better hearing. Other variables found to be associated with hearing levels included: years listening to PLD, number of noise environments and use of ear protection. Finally, a healthy waist-to-hip ratio was a significant predictor of better hearing, while body mass index approached, but did not reach statistical significance.
Full Text Available Background and Aim: Turner syndrome is the most common sex chromosome abnormality in females, affecting an estimated 3% of all conceiving females. Otologic disease is a common problem in Turner syndrome patients that is due to a combination of small dysfunction Eustachian tube, palatal dysfunction and cochlear malformation.Methods: This study assessed the otologic and audiologic characteristics of a group of Turner syndrome patients. We studied 40 Turner patients aged 10 to 20 years (mean age: 15.84 years, SD=2.67. Pure tone audiometry was carried out for all of them.Results: Forty percent of the patients reported a history of middle ear disease. Analysis of audiometric data in 40 patients tested reveals normal hearing in 47.5%, pure sensorineural hearing loss in 32.5%, pure conductive hearing loss in 17.5% and mixed hearing loss in 2.5% of patients.Conclusion: Careful follow up during early childhood of children with Turner syndrome is necessary to detect middle ear disease and prevent the probable sequel. However, long term periodic follow up is mandatory even after resolution of middle ear disease to detect sensorineural hearing loss
This document is a supplement to the year 2007 position statement of the Joint Committee on Infant Hearing and provides comprehensive guidelines for establishing strong early intervention (EI) systems with appropriate expertise to meet the needs of children who are deaf or hard of hearing (D/HH). Optimal outcomes can only be achieved when there is high quality to the universal newborn hearing screening programs, the audiologic diagnostic process of confirmation that a child is D/HH and fitting of amplification, and the provision of appropriate, individualized, targeted, and high-quality EI services. There are 12 best practice guidelines for EI programs that include the provision of timely referral to EI services with providers who have knowledge and skills in early childhood deafness and hearing loss, infusion within the system of partnerships with parents as well as professionals who are D/HH, longitudinal developmental assessments for monitoring the child's development, data management systems that include developmental outcomes, a process to monitor the fidelity of the intervention, and appropriate services for children with additional disabilities, those from non-English speaking families, and those from special populations, including unilateral hearing loss and auditory neuropathy/dyssynchrony.

We formulated policies and procedures for allied health professionals (AHPs) who provide services using telehealth in Nunavut, Canada's newest Arctic territory. These are a supplement to the clinical policies and procedures already established for Nunavut physicians and nurses. The services were in the areas of audiology, dietetics/nutrition, midwifery, occupational therapy, ophthalmic services, pharmacy, physiotherapy, psychology, respiratory therapy, social work and speech therapy. Documents specific to each of the services were developed, drawing on information from Government of Nunavut data, Nunavut healthcare providers and links made through the Internet. Topics included the scope and limitations of telehealth services, staff responsibilities, training and reporting, professional standards and cultural considerations. We also considered generic policies covering common issues such as jurisdiction, licensing and liability. The policies and procedures for AHPs will enhance and expand the successes already achieved with telehealth in Nunavut. The challenges are to balance the preferred approaches to service provision with the realities of health care and communications in an Arctic setting. PMID:16375792

Introduction The presence of noise in our society has attracted the attention of health professionals, including speech-language pathologists, who have been charged along with educators with developing hearing conservation programs in schools. Objective To describe the results of three strategies for awareness and hearing preservation in first to fourth grades in public elementary schools. Methods The level of environmental noise in classrooms was assessed, and 638 elementary school students from first to fourth grades, 5 to 10 years of age, were audiologically evaluated. After the evaluations, educational activities were presented to children and educators. Results The noise level in the classroom ranged from 71.8 to 94.8 A-weighted decibels. The environment of the classroom was found to promote sound reverberation, which hinders communication. Thirty-two students (5.1%) presented hearing alterations. Conclusion The application of strategies for a hearing conservation program at the school showed that noise is present in the room, and hearing loss, sometimes silent, affects schoolchildren. Students and teachers were aware that hearing problems can be prevented. Avoiding exposure to noise and improving the acoustics in classrooms are essential. PMID:25992146

Full Text Available Introduction: Hearing loss causes difficulties in speech understanding, which leads away from the family and social environment. This isolation may be associated with depressive disorders. Type of study: clinical prospective. Objective: To determine the association between hearing loss and depression in a group of non-institutionalized elderly. Method: The sample consisted of individuals aged over 60 years, undergoing complete audiological evaluation and screening for depressive symptoms with the Geriatric Depression Scale (GDS. Results: We evaluated 54 elderly, 26 (48.1% were female and 28 (51.9% males. It was found that 39 (72.2% had hearing thresholds change, and 17 (31.5% with mild hearing loss and 22 (40.7% with moderate hearing loss. Were evident signs of depression in 25 elderly (46.3%, and 22 (40.7% had hearing loss. Data analysis showed an association between hearing loss and depression (p = 0.016. Although not significant (p = 0.18, the association between the degree of hearing loss was positive in relation to the severity of the signs of depression. Conclusion: In elderly people surveyed, there was a strong association between hearing loss and signs of depression and tendency to be an association between the degree of hearing loss and the severity of the signs of depression.

It shows motor signs and symptoms characterized by trembling, postural instability, rigidity and bradykinesia. Objective: To evaluate the central hearing function in PD patients. Method: A descriptive, prospect and transversal study, in which 10 individuals diagnosed of PD named study group (SG and 10 normally hearing individuals named control group (CG were evaluated, age average of 63.8 and (SD 5.96. Both groups went through otorhinolaryngological and ordinary audiological evaluations, and dichotic test of alternate disyllables (SSW. Results: In the quantitative analysis, CG showed 80% normality on competitive right-ear hearing (RC and 60% on the competitive left-ear hearing (LC in comparison with the SG that presented 70% on RC and 40% on LC. In the qualitative analysis, the biggest percentage of errors was evident in the SG in the order effect. The results showed a difficulty in identifying a sound when there is another competitive sound and in the memory ability. Conclusion: A qualitative and quantitative difference was observed in the SSW test between the evaluated groups, although statistical data does not show significant differences. The importance to evaluate the central hearing process is emphasized when contributing to the procedures to be taken at the therapeutic follow-up.

Tinnitus, as a phantom sound can express itself as a pure tone and as a noise-like sound. It is notoriously difficult to treat, and in medically, psychologically and audiologically intractable tinnitus patients sometimes intracranial electrodes overlying the auditory cortex are implanted. In this case report, we describe a patient who had a complete resolution of the pure tone component of his tinnitus by an auditory cortex implant, without any beneficial effect on the noise-like aspect of his tinnitus, even after changing the stimulation design to burst stimulation, which is known to treat noise-like tinnitus better than tonic stimulation. After an initial successful treatment of his noise-like component with transcutaneus electrical nerve stimulation, a wire electrode is inserted subcutaneously and connected to his internal pulse generator. With the dual stimulation his pure tone tinnitus remains abolished after 5 years of stimulation and his noise-like tinnitus is improved by 50%, from 8/10 to 4/10. This case report suggests that multi-target stimulation might be better than single target implantation in selected cases. PMID:25703225

Full Text Available OBJECTIVES: This study investigated whether neurophysiologic responses (auditory evoked potentials differ between typically developed children and children with phonological disorders and whether these responses are modified in children with phonological disorders after speech therapy. METHODS: The participants included 24 typically developing children (Control Group, mean age: eight years and ten months and 23 children clinically diagnosed with phonological disorders (Study Group, mean age: eight years and eleven months. Additionally, 12 study group children were enrolled in speech therapy (Study Group 1, and 11 were not enrolled in speech therapy (Study Group 2. The subjects were submitted to the following procedures: conventional audiological, auditory brainstem response, auditory middle-latency response, and P300 assessments. All participants presented with normal hearing thresholds. The study group 1 subjects were reassessed after 12 speech therapy sessions, and the study group 2 subjects were reassessed 3 months after the initial assessment. Electrophysiological results were compared between the groups. RESULTS: Latency differences were observed between the groups (the control and study groups regarding the auditory brainstem response and the P300 tests. Additionally, the P300 responses improved in the study group 1 children after speech therapy. CONCLUSION: The findings suggest that children with phonological disorders have impaired auditory brainstem and cortical region pathways that may benefit from speech therapy.

The objective of the present study was to determine the main lines of the development of a regional cochlear implantation centre and to estimate the effectiveness of rehabilitation of the children treated with the use of cochlear implantation. Analysis of the results of the work of the branch of the Russian Research and Practical Centre of Audiology and Hearing Rehabilitation based at Voronezh Regional Children's Clinical Hospital No 1 provided materials for the establishment of the principle directions of activities of the regional cochlear implantation centre where a total of 161 children have been kept under observation during the last years. Fifty six of the 138 children at the age varying from 1 to 12 years were given the surgical treatment. The patients were followed up within two and more years after connection of the speech processor. The study group was comprised only of the pre-lingually deaf children. It is concluded that the performance of most cochlear implantation procedures based at local centres allows to reduce the cost of rehabilitation and makes the high-tech medical aid more readily available to the patients; moreover, the practical introduction of remote speech processor programming software into the work of regional cochlear implantation centres enhances the effectiveness of the rehabilitative measures based at local medical facilities.

When hearing aid gain is prescribed by software, gain is calculated based on the average acoustics for the age of patient, gender, mold type, and so on. The acoustics of the individual's ear often vary from the average values, so there will be a mismatch between the prescribed gain and the real-ear gain. Real-ear measurement can be used to verify the gain and adjust it to meet targets, but the quality of the match will be limited by the number of channels and the flexibility of the hearing aid. A potential way to improve this process is to generate a filter that compensates for variations in real-ear insertion gain due to individual ear acoustics. Such a filter could be included in the processing path of a digital hearing aid. This article describes how such a filter can be generated using the windowing method, and the principle is demonstrated in a real ear. The approach requires communication between the real-ear measurement and hearing aid programming software. A finite impulse response filter with group delay just over 2 ms matched insertion gain to target values within the acceptable tolerance defined by British Society of Audiology guidelines.

Full Text Available BACKGROUND: Branchio-oto-renal (BOR or branchio-otic (BO syndrome is one of the most common forms of autosomal dominant syndromic hearing loss. Mutations in EYA1, SIX1 and SIX5 genes have been associated with BOR syndrome. In this study, clinical and genetic analyses were performed in patients with BOR/BO syndrome focusing on auditory manifestations and rehabilitation. METHODS: The audiologic manifestations were reviewed in 10 patients with BOR/BO syndrome. The operative findings and hearing outcome were analyzed in patients who underwent middle ear surgeries. The modality and outcome of auditory rehabilitation were evaluated. Genetic analysis was performed for EYA1, SIX1, and SIX5 genes. RESULTS: All patients presented with mixed hearing loss. Five patients underwent middle ear surgeries without successful hearing gain. Cochlear implantation performed in two patients resulted in significant hearing improvement. Genetic analysis revealed four novel EYA1 mutations and a large deletion encompassing the EYA1 gene. CONCLUSIONS: Auditory rehabilitation in BOR/BO syndrome should be individually tailored keeping in mind the high failure rate after middle ear surgeries. Successful outcome can be expected with cochlear implantations in patients with BOR/BO syndrome who cannot benefit from hearing aids. The novel EYA1 mutations may add to the genotypic and phenotypic spectrum of BOR syndrome in the East Asian population.

Manufacturing techniques for production of small precise metallic parts has gained interest during recent years, an interest led by an industrial demand for components for integrated products like mobile phones, personal digital assistants (PDAs), mp3-players and in the future for spare parts for the human body. Micro components have also found several applications within the medical, audiological and dental industry, applications that impose increased demands for biocompatible and corrosion-resistant materials and cleanness. So far these micro components have mainly been manufactured by traditional machining techniques or chemical etching. However, these traditional machining and etching techniques are generally not well suited for mass production of advanced micro components, due to handling problems, waste of expensive material and long machining times. This calls for development of a novel production system that can meet the demands for high productivity, high reliability, low cost, while being environmental acceptable. Bulk metal forming meets these demands to a great extent, but the technology cannot directly be transferred to the micro scale. A flexible machine system for bulk micro forming has been developed and used to form a number of industrial micro parts in aluminium and silver, with ongoing work on forming of titanium. Manufacture of billets by cropping has been examined using a simple test rig and an automatic cropping device has been designed, manufactured and tested.

Full Text Available Michael P Cannito, Joel C Kahane, Lesya ChornaSchool of Audiology and Speech-Language Pathology, The University of Memphis, Memphis, TN, USAAbstract: Aging of the larynx is characterized by involutional changes which alter its biomechanical and neural properties and create a biological environment that is different from younger counterparts. Illustrative anatomical examples are presented. This natural, non-disease process appears to set conditions which may influence the effectiveness of botulinum toxin injection and our expectations for its success. Adductor spasmodic dysphonia, a type of laryngeal dystonia, is typically treated using botulinum toxin injections of the vocal folds in order to suppress adductory muscle spasms which are disruptive to production of speech and voice. A few studies have suggested diminished response to treatment in older patients with adductor spasmodic dysphonia. This retrospective study provides a reanalysis of existing pre-to-post treatment data as function of age. Perceptual judgments of speech produced by 42 patients with ADSD were made by two panels of professional listeners with expertise in voice or fluency of speech. Results demonstrate a markedly reduced positive response to botulinum toxin treatment in the older patients. Perceptual findings are further elucidated by means of acoustic spectrography. Literature on vocal aging is reviewed to provide a specific set of biological mechanisms that best account for the observed interaction of botulinum toxin treatment with advancing age.Keywords: vocal aging, adductor spasmodic dysphonia, botulinum toxin, voice quality, speech fluency

Full Text Available Tinnitus is characterized by an auditory perception of sound, with no stimuli from the external environment. Tinnitus is an increasingly significant complaint, affecting 10-17% of the world population. As a symptom, it should always be considered with pathology in the auditory system. Our study aims to assess the relationship of this symptom with the presence of a stapedial reflex and the phenomenon of recruitment. Medical records of patients complaining of subjective tinnitus during their first consultation in the Outpatient Clinic of the Unicamp Teaching Hospital, in Brazil, between 2011 and 2012 were analyzed. We carried out a study with 65 non-randomized tinnitus individuals using questionnaires, clinical and audiological evaluations. The visual analogue scale was used to characterize the degree of disturbance caused by tinnitus. Statistical tests were performed using the IBM SPSS Statistics 19. No association was found between tinnitus and the presence of acoustic reflex or phenomenon of recruitment. We concluded that there is no relationship between tinnitus, the phenomenon of recruitment or the presence of an acoustic reflex.

Full Text Available The main clinical presentation of patients with primary antibody deficiency (PAD incorporates upper respiratory tract infections comprising otitis media, sinusitis and pneumonia. This study was designed to investigate clinical and paraclinical otological complications in major types of PAD. A cross sectional study was conducted on 55 PAD patients with diagnosis of selective IgA deficiency, common variable immunodeficiency (CVID, X-linked agammaglobulinemia (XLA, and hyper IgM syndrome. All patients underwent otological examinations, audiometry, and auditory brain stem response. Otological complications were detected in 54.5% of PAD patients. Conductive hearing loss was the main finding amongst PID patients (73.3% followed by sensorineural hearing loss which was present in 8 cases. Otitis media with effusion (21.8%, chronic otitis media (27.2%, tympanosclerosis with intact tympanic membrane (5.4% and auditory neuropathy (3.6% were most important found complications. CVID and XLA patients with prophylactic usage of antibiotics had lower rate of audiological complications (p=0.04 and otitis media with effusion (p=0.027. As our results showed, asymptomatic otological findings were not rare in PAD patients; therefore, a systematic otological investigation is recommended as an integral part of the management and follow-up of these patients.

This paper provides a look at how modulated broad-band noises modulate the thalamic response evoked by brief probe sounds in the awake animal. We demonstrate that noise not only attenuates the response to probe sounds (masking) but also changes the temporal response pattern (scrambling). Two brief probe sounds, a Gaussian noise burst and a brief sinusoidal tone, were presented in silence and in three ongoing noises. The three noises were targeted at activating the auditory system in qualitatively distinct ways. Dynamic ripple noise, containing many random tone-like elements, is targeted at those parts of the auditory system that respond well to tones. International Collegium of Rehabilitative Audiology noise, comprised of the sum of several simultaneous streams of Schroeder-phase speech, is targeted at those parts of the auditory system that respond well to modulated sounds but lack a well defined response to tones. Gaussian noise is targeted at those parts of the auditory system that respond to acoustic energy regardless of modulation. All noises both attenuated and decreased the precise temporal repeatability of the onset response to probe sounds. In addition, the modulated noises induced context-specific changes in the temporal pattern of the response to probe sounds. Scrambling of the temporal response pattern may be a direct neural correlate of the unfortunate experience of being able to hear, but not understand, speech sounds in noisy environments.

Auditory neuropathy spectrum disorder (ANSD) is a retrocochlear disorder in which the cochlear functioning is normal but the transmission in the auditory neural pathway is affected. The present study reports of a 14-year-old teenager with acquired ANSD after an attack of chikungunya. He reported symptoms of difficulty in understanding speech, tinnitus and vertigo when exposed to loud sounds. The audiological characteristics suggested auditory neuropathy spectrum disorder with raising audiogram configuration. The results of tinnitus evaluation showed low-pitched tinnitus and it was persistent causing significant handicap to him based on self report tinnitus handicap questionnaire results. The results of depression, anxiety and stress scale also suggested symptoms of mild depression and anxiety. Chikungunya virus is suspected to be neurotropic in nature which can damage auditory nerve cells and may have caused ANSD. The result also shows presence of tullio's phenomenon and absence of cervical vestibular evoked myogenic potentials suggesting damage to the vestibular neuronal system. The possible pathophysiology of chikungunya virus causing ANSD and vestibular symptoms needs to be explored further in future studies. PMID:25728940

Background According to the guidelines of the European Scientific Consensus on Hearing (European Federation of Audiology Societies ‘EFAS’ Congress, June 2011, Warsaw, Poland), the detection and treatment of communication disorders in early school-age children is of the highest importance. This objective was adopted by the Polish president of the EFAS Council from the second half of 2011; as a result, pilot programs on children’s hearing screening were initiated in various European countries. This paper reports data from a pilot program in Dushanbe, Tajikistan. Material/Methods We randomly selected 143 children from 2 primary schools. Each child was assessed by pure tone audiometry and 2 questionnaires (dedicated to parents and children). The study allowed the validation of: (i) hearing screening procedures in young children, and (ii) data collection via a telemedicine model. Results Hearing impairments were identified in 34 cases (23.7%) with a 50% ratio between unilateral and bilateral losses. We found a higher incidence of hearing impairment in children than that reported in previous Polish studies. Conclusions The data from the present study suggest that it is possible to use a telemedicine model to assess the hearing status of children and to provide a long-distance expert assistance. The latter is very important for rural areas without specialized medical services. PMID:27402315

Most tinnitus studies have attempted to compare groups of individuals, thus revealing inter-individuals differences, i.e., variations between compared subjects. For methodological reasons, inter-individual studies cannot take into account the variability of tinnitus experience, which has been known for decades to be relevant in daily practice with tinnitus patients. The concept of intra-individual variability has been promoted in the research literature, in order to shed light on this aspect of individual perception. In previous studies, unrelated to hearing, the concept of intra-individual variability implied inclusion of the environment (i.e., physical and social interactions) as a factor of individual performance. In tinnitus research, we believe that the concept of variability (within a person) could find a place beside the concept of variation (between groups of subjects). In this paper, four perspectives of tinnitus experiences from the clinical and research fields are described: (1) ENT consultation; (2) short-term group psychotherapy; (3) psychodynamic psychotherapy; and (4) clinical psychological research. Intra-individual variability stresses the importance of defining tinnitus in a dynamic way, contrary to the current definition of tinnitus as the perception of sound(s). In clinical practice, it is useful to embrace the perspective of the perceiver of tinnitus, and to include social and cultural circumstances as well as audiological/physical changes. PMID:25862625

Mucopolysaccharidosis type I-Hurler syndrome (MPS-IH) is a lysosomal storage disease characterized by multisystem morbidity and death in early childhood. Although hematopoietic cell transplantation (HCT) has been performed in these patients for more than 30 years, large studies on the long-term outcome of patients with MPS-IH after HCT are lacking. The goal of this international study was to identify predictors of the long-term outcome of patients with MPS-IH after successful HCT. Two hundred seventeen patients with MPS-IH successfully engrafted with a median follow-up age of 9.2 years were included in this retrospective analysis. Primary endpoints were neurodevelopmental outcomes and growth. Secondary endpoints included neurologic, orthopedic, cardiac, respiratory, ophthalmologic, audiologic, and endocrinologic outcomes. Considerable residual disease burden was observed in the majority of the transplanted patients with MPS-IH, with high variability between patients. Preservation of cognitive function at HCT and a younger age at transplantation were major predictors for superior cognitive development posttransplant. A normal α-l-iduronidase enzyme level obtained post-HCT was another highly significant predictor for superior long-term outcome in most organ systems. The long-term prognosis of patients with MPS-IH receiving HCT can be improved by reducing the age at HCT through earlier diagnosis, as well as using exclusively noncarrier donors and achieving complete donor chimerism.

Full Text Available Introduction: The Auditory Neuropathy is described recently as a hearing loss characterized by the preservation of outer hair cells and absence of auditory brainstem responses. Objective: To present a case report of hearing aid fitting in a patient with Auditory Neuropathy. Case Report: S.A.P., male, 32 years old, sought the Otorhinolaryngology Service after five years of Guillain-Barré syndrome, complaining of progressive and bilateral tinnitus auditory loss in both ears. The audiological evaluation resulted in: severe sensorioneural hearing deficiency with bilateral irregular configuration; speech recognition rate of 0% and speech detection rate in 35dB in both ears; type A tympanometric curve and absent ipsilateral, bilateral and contralateral reflexes; absence of waves and presence of cochlear microphonics in both ears in the auditory evoked potential and present bilateral distortion product-evoked otoacoustic emissions. The speech perception test was performed with polysyllabic words and lip reading, and presented 44% of hit with hearing aid and 12% without it. Final Comments: Despite the differences in the process of hearing aid habilitation and rehabilitation, we conclude that sound amplification brought benefits to the patient with auditory neuropathy.
Full Text Available The masking effect of a piano composition, played at different speeds and in different octaves, on speech-perception thresholds was investigated in 15 normal-hearing and 14 moderately-hearing-impaired subjects. Running speech (just follow conversation, JFC testing and use of hearing aids increased the everyday validity of the findings. A comparison was made with standard audiometric noises [International Collegium of Rehabilitative Audiology (ICRA noise and speech spectrum-filtered noise (SPN]. All masking sounds, music or noise, were presented at the same equivalent sound level (50 dBA. The results showed a significant effect of piano performance speed and octave (P<.01. Low octave and fast tempo had the largest effect; and high octave and slow tempo, the smallest. Music had a lower masking effect than did ICRA noise with two or six speakers at normal vocal effort (P<.01 and SPN (P<.05. Subjects with hearing loss had higher masked thresholds than the normal-hearing subjects (P<.01, but there were smaller differences between masking conditions (P<.01. It is pointed out that music offers an interesting opportunity for studying masking under realistic conditions, where spectral and temporal features can be varied independently. The results have implications for composing music with vocal parts, designing acoustic environments and creating a balance between speech perception and privacy in social settings.

Hearing loss is a common disability in the United States, most frequent among men, elderly individuals, and veterans but is increasingly affecting other younger adults. Types of hearing loss include sensorineural, conductive, and mixed. Hearing loss in children often is related to infections, time spent in a neonatal intensive care unit, and genetic etiologies. Presbycusis (ie, age-related hearing loss) is the most common etiology in adults. Adverse effects of untreated hearing loss include isolation, depression, lower income, and higher unemployment. Hearing aid use reduces levels of disability, cognitive impairment, and psychosocial distress while improving quality of life. At least 75% of individuals with hearing loss are not receiving treatment for it. All infants should be screened for hearing loss, as should children and adults with risk factors. The Joint Commission on Infant Hearing Screening has a 1-3-6 goal for screening: identification by age 1 month, confirmation by age 3 months, and intervention by age 6 months. The presence of an ongoing physician-patient relationship increases the likelihood that a patient will admit to having a hearing loss. Adults can be screened using single-question or standardized instrument screens. All patients with suspected hearing loss should undergo audiometry by an audiology subspecialist. PMID:26161523

Objective: This paper provides an overview of the state of evidence-based practice (EBP) in nursing and selected allied health professions and a synopsis of current trends in incorporating EBP into clinical education and practice in these fields. This overview is intended to better equip librarians with a general understanding of the fields and relevant information resources. Included Professions: Professions are athletic training, audiology, health education and promotion, nursing, occupational therapy, physical therapy, physician assisting, respiratory care, and speech-language pathology. Approach: Each section provides a description of a profession, highlighting changes that increase the importance of clinicians' access to and use of the profession's knowledgebase, and a review of each profession's efforts to support EBP. The paper concludes with a discussion of the librarian's role in providing EBP support to the profession. Conclusions: EBP is in varying stages of growth among these fields. The evolution of EBP is evidenced by developments in preservice training, growth of the literature and resources, and increased research funding. Obstacles to EBP include competing job tasks, the need for additional training, and prevalent attitudes and behaviors toward research among practitioners. Librarians' skills in searching, organizing, and evaluating information can contribute to furthering the development of EBP in a given profession. PMID:17971887

The present study focused on the comparison of mental health and quality of life (QoL) between chronic otitis media (COM) patients and the hearing population. The patients with chronic otitis media and healthy control group were enrolled in the study. The duration and severity of the auditory impairment were recorded. In addition to hearing loss (HL), the findings of each patient's other ear disorders (ear discharge and tinnitus) were also recorded. In both the groups, psychological symptom profile and health-related QoL were evaluated and compared using a sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R), and the Short Form-36 (SF-36). According to SCL-90-R, somatization (p depression (p social functioning (p < 0.001), and mental health (p < 0.017) than those of control subjects. Our results indicated that COM patients with mild or moderate HL have poorer life quality and higher psychological problems. Psychological well being should be also considered in assessment of COM patients in addition to the clinical evaluation and audiological tests. PMID:22566178

It has been generally accepted that excessive exposure to loud music causes various hearing symptoms (e.g. tinnitus) and consequently leads to a risk of permanent hearing damage, known as noise-induced hearing loss (NIHL). Such potential risk of NIHL due to loud music exposure has been widely investigated in musicians and people working in music venues. With advancements in sound technology and rapid developments in the music industry, increasing numbers of people, particularly adolescents and young adults, are exposing themselves to music on a voluntary basis at potentially harmful levels, and over a substantial period of time, which can also cause NIHL. However, because of insufficient audiometric evidence of hearing loss caused purely by music exposure, there is still disagreement and speculation about the risk of hearing loss from music exposure alone. Many studies have suggested using advanced audiological measurements as more sensitive and efficient tools to monitor hearing status as early indicators of cochlear dysfunction. The purpose of this review is to provide further insight into the potential risk of hearing loss caused by exposure to loud music, and thus contribute to further raising awareness of music induced hearing loss.

Auditory processing disorder (APD) is diagnosed when a patient presents with listening difficulties which can not be explained by a peripheral hearing impairment or higher-order cognitive or language problems. This review explores the association between auditory processing disorder (APD) and other specific developmental disorders such as dyslexia and attention-deficit hyperactivity disorder. The diagnosis and aetiology of APD are similar to those of other developmental disorders and it is well established that APD often co-occurs with impairments of language, literacy, and attention. The genetic and neurological causes of APD are poorly understood, but developmental and behavioural genetic research with other disorders suggests that clinicians should expect APD to co-occur with other symptoms frequently. The clinical implications of co-occurring symptoms of other developmental disorders are considered and the review concludes that a multi-professional approach to the diagnosis and management of APD, involving speech and language therapy and psychology as well as audiology, is essential to ensure that children have access to the most appropriate range of support and interventions.

Sensorineural hearing loss (SNHL) is one of the major long term side effects from radiation therapy (RT) in nasopharyngeal cancer (NPC) patients. This study aims to review the incidences of SNHL when treating with different radiation techniques. The additional objective is to determine the relationship of the SNHL with the radiation doses delivered to the inner ear. A retrospective cohort study of 134 individual ears from 68 NPC patients, treated with conventional RT and IMRT in combination with chemotherapy from 2004-2008 was performed. Dosimetric data of the cochlea were analyzed. Significant SNHL was defined as > 15 dB increase in bone conduction threshold at 4 kHz and PTA (pure tone average of 0.5, 1, 2 kHz). Relative risk (RR) was used to determine the associated factors with the hearing threshold changes at 4 kHz and PTA. Median audiological follow up time was 14 months. The incidence of high frequency (4 kHz) SNHL was 44% for the whole group (48.75% in the conventional RT, 37% with IMRT). Internal auditory canal mean dose of > 50 Gy had shown a trend to increase the risk of high frequency SNHL (RR 2.02 with 95% CI 1.01-4.03, p = 0.047). IMRT and radiation dose limitation to the inner ear appeared to decrease SNHL

Only few studies have focused on neurosensory hearing function of patients with congenital hypothyroidism (CH) identified by CH screening programs and treated early and, therefore, this issue remains still controversial. The aim of this study was to ascertain whether an early and adequate replacement treatment may be able to prevent sensorineural hearing loss in 32 screened children with CH and no associated risk factors for neuro-otologic alterations. These patients were recruited according to highly selective criteria aiming to preliminarily exclude the negative interference of both treatment variables and other underlying risk factors. All the selected patients underwent, at a median age of 15.4 years, an audiologic investigation, which evidenced a mild and subclinical hearing loss in 25% of them. The poorest hearing scores were recorded in the individuals with athyreosis and in those with absence of distal femur bony nucleus at CH diagnosis. The prevalence of hearing impairment was significantly higher in CH patients than in 32 age-matched control subjects with no CH (χ(2) = 6.3, p treatment; b) the risk of hearing loss is higher in CH young patients than in age-matched control subjects without CH; c) the risk of hearing loss is closely associated with the severity of CH; d) this risk is particularly relevant in the children with pre-natal onset of hypothyroidism.

This study set out to determine the pattern and predictors of noise-induced hearing loss (NIHL) among small-scale and self-employed chili pepper grinders in Lagos, Southwest Nigeria. Audiological evaluation was conducted for all participants after noise level measurement. Of 136 studied, 85 (62.5%) were confirmed with slight-to-moderate NIHL. Mean age was 40.2 years, mean years spent as grinders was 9.3 years and mean hours spent daily at work was 13.3 hours. The mean age of those with NIHL was significantly higher than those without. Spending over 10 years in commercial grinding and working ≤12 hours daily were predictive of NIHL. Questionnaire-based screening using symptoms of NIHL was associated with a sensitivity of 44.7%, specificity of 62.7%, and positive predictive value of 66.7%. In conclusion, pepper grinding is associated with high/excessive noise levels and NIHL. Hearing conservation program incorporating engineering modification of locally fabricated grinders is warranted in this and similar populations in developing countries. PMID:22173475

Objective: To analyze neurophysiological characteristics in infants and young children with auditory neuropathy (AN) and explore their clinical significance. Methods: Audiological measurements(acoustic immittance, EOAEs, ABR, CM, MLR and ERPs) and peripheral neurological tests were conducted and evaluated in 13 infants and young children with AN. Six of them received highresolution temporal bone CT scans and/or cerebral MRI examinations. Results: All of the children showed type "A" tympanograms with abseatation of stapedial reflexes. EOAEs were normal in 12 of 13 subjects. In one child who had a history of anoxia during the birth, the EOAEs were not elicited. Click-evoked ABRs were absent in 12 of 13 subjects when maximum output of the instrument was reached. The CM potentials were presented bilaterally in all individuals, which were independent of the EOAEs and ABR. Of eight cases tested, all had clear MLR and six showed normal ERPs(P300 and MMN). Peripheral neurological tests and radiological findings were within the normal ranges. Conclusion: The diagnosis of AN in infants and young children should focus on analyzing their neurophysiological characteristics,especially on CM,MLR and ERPs. Combined use of EOAEs, ABR and CM was recommended for hearing screening on newborns with high risk factors.

Full Text Available Introduction: Acoustic nerve tumors have been recognized as a clinico-pathologic entity for at least 200 years, and they represent 90% of cerebellopontine angle diseases. Histologically, the tumors are derived from Schwann cells of the myelin sheath, with smaller tumors consisting of elongated palisade cells, while in large tumors, cystic degeneration can be found in the central areas, possibly due to deficient vascularization. We retrospectively reviewed 825 cases of vestibular schwannomas, reported between January 1984 and August 2006, in which the patients underwent surgery to remove the tumor. Objective: To evaluate signs, symptoms, aspects of clinical diagnosis, including the results of audiological and imaging studies, and surgical techniques and complications. Methods: A retrospective chart review. The medical records of all patients undergoing surgical treatment for schwannoma during the period indicated were reviewed. Results and Conclusion: Hearing loss was the first symptom reported in almost all cases, and tumor size was not proportional to the impairment of the auditory threshold. The surgical techniques allowed safe preservation of facial function. In particular, the retrolabyrinthine route proved useful in small tumors, with 50% preservation of hearing.

Background There has been increasing demand for the cochlear implantation of children who demonstrate some auditory capacity with conventional hearing aids. The purpose of this study was to examine speech recognition outcomes in a group of children who were regarded as borderline candidates for cochlear implantation as their residual hearing and/or auditory functioning levels exceeded typical audiologic candidacy criteria. Methods A retrospective chart review was undertaken at one Canadian cochlear implant centre to identify children implanted at age 4 or older with a pure-tone-average of 90 dB or better and speech recognition of 30% or greater. Pre-implant and post-implant open-set word and sentence test scores were analyzed. Results Eleven children of 195 paediatric cochlear implant recipients met the inclusion criteria for this study. Speech recognition results for the10 English-speaking children indicated significant gains in both open-set word and sentence understanding within the first 6 to 12 months of implant use. Seven of 9 children achieved 80% open-set sentence recognition within 12 months post-surgery. Conclusion Children with several years of experience using conventional amplification demonstrated rapid progress in auditory skills following cochlear implantation. These findings suggest that cochlear implantation may be an appropriate intervention for selected children with severe hearing losses and/or auditory capacity outside current candidacy criteria.

Full Text Available Objective: To describe a case of hearing rehabilitation with bone anchored hearing aid in a patient with Treacher Collins syndrome. Case description: 3 years old patient, male, with Treacher Collins syndrome and severe complications due to the syndrome, mostly related to the upper airway and hearing. He had bilateral atresia of external auditory canals, and malformation of the pinna. The initial hearing rehabilitation was with bone vibration arch, but there was poor acceptance due the discomfort caused by skull compression. It was prescribed a model of bone-anchored hearing aid, in soft band format. The results were evaluated through behavioral hearing tests and questionnaires Meaningful Use of Speech Scale (MUSS and Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS. Comments: The patient had a higher acceptance of the bone-anchored hearing aid compared to the traditional bone vibration arch. Audiological tests and the speech and auditory skills assessments also showed better communication and hearing outcomes. The bone-anchored hearing aid is a good option in hearing rehabilitation in this syndrome.
Full Text Available INTRODUCTION: Turner's syndrome (TS is caused by a partial or total deletion of an X chromosome, occurring in 1:2,000 to 1:5,000 live born females. Hearing loss is one of its major clinical manifestations. However, there are few studies investigating this problem. OBJECTIVES: To review the current knowledge regarding the epidemiology, etiology, clinical manifestations and diagnosis of hearing impairment in patients with TS. METHODS: A bibliographic search was performed in the Medline and Lilacs databanks (1980-2012 to identify the main papers associating Turner's syndrome, hearing impairment and its clinical outcomes. CONCLUSIONS: Recurrent otitis media, dysfunction of the Eustachian tube, conductive hearing loss during infancy and sensorineural hearing loss in adolescence are the audiologic disorders more common in ST. The karyotype appears to be important in the hearing loss, with studies demonstrating an increased prevalence in patients with monosomy 45,X or isochromosome 46,i(Xq. Morphologic studies of the cochlea are necessary to help out in the clarifying the etiology of the sensorineural hearing loss.
Full Text Available Background and Aim: Preterm birth is one of the risk factors need comprehensive audiological assessment. In this study, the effect of sex and rate of stimulation on response of children with history of preterm birth was investigated by auditory brainstem response (ABR. Methods: This cross-sectional study was conducted using convinience sampling. Click-evoked a uditory brainstem response test with both low (21.1 c/s and high (51.1 c/s stimulus rates was recorded in 30 children with a history of preterm birth and 30 ones with history of term labor, as controls. Results: Significant differences were observed in inter-peak latencies of I-III in both rates, III-V in the low rate, I-V in the high rate, and absolute latency of III wave between high and low stimulus rates (p<0.05 for all. Rate of stimulus affect on auditory brainstem response of preterm birth group was more than controls. Sex also affected on some parameters of auditory brainstem response test. Conclusion: Preterm birth group showed longer latencies than normal group in both rates. Rate of stimulus had significant effect on results of children with history of preterm birth compared normal group. These findings may reflect the negative effect of preterm birth on neural synchronization function in response to transient stimuli.
Full Text Available BACKGROUND: The prevalence of isolated hearing loss (HL associated with the m.3243A>G mutation is unknown. The aim of this study was to assess the frequency and heteroplasmy level of the m.3243A>G mutation in a large group of Polish patients with postlingual bilateral sensorineural HL of unidentified cause. METHODOLOGY/PRINCIPAL FINDINGS: A molecular search was undertaken in the archival blood DNA of 1482 unrelated patients with isolated HL that had begun at ages between 5 and 40 years. Maternal relatives of the probands were subsequently investigated and all carriers underwent audiological tests. The m.3243A>G mutation was found in 16 of 1482 probands (an incidence of 1.08% and 18 family members. Of these 34 individuals, hearing impairment was detected in 29 patients and the mean onset of HL was at 26 years. Some 42% of the identified m.3243A>G carriers did not develop multisystem symptomatology over the following 10 years. Mean heteroplasmy level of m.3243A>G was lowest in blood at a level of 14% and highest in urine at 58%. These values were independent of the manifested clinical severity of the disease. CONCLUSIONS: A single m.3243A>G carrier can usually be found among each 100 individuals who have postlingual hearing loss of unknown cause. Urine samples are best for detecting the m.3243A>G mutation and diagnosing mitochondrially inherited hearing loss.
Because of the relative frequency of speech/language delay, all infants and preschool children should undergo routine language screening as part of health care maintenance. Diagnostic evaluation of the child with speech or language delay should answer the following questions: What is the child's descriptive diagnosis (eg, hearing impaired, mentally retarded, DLD, etc.)? What is the child's etiologic diagnosis (eg, congenital viral infection, single gene disorder, birth asphyxia, etc.)? What is the appropriate intervention strategy (amplification, orally based speech therapy, total communication, "infant stimulation" program, etc.)? What is this child's long-term prognosis, to the extent that this is knowable? All children with speech or language delay should undergo formal audiologic testing, regardless of how well the child seems to hear in an office setting, and regardless of whether other disabilities are present which might independently explain the speech/language delay. Evaluation by a psychologist, a speech/language pathologist, or both should follow, with referral to an appropriate intervention program based upon the results of formal developmental testing. Additional medical evaluation (eg, CAT scan, EEG, karyotype), and genetic counseling must be determined on a case-by-case basis. Long-term follow-up should include an awareness that speech or language delay during the preschool years often signifies long-term developmental difficulties, warranting close follow-up of such children as they advance through the school age years.

The objective of this study was to evaluate hearing impairment in patients affected by Parkinson's disease compared with hearing scores observed in normal age- and sex-matched controls. One hundred eighteen consecutive patients with a clinical diagnosis of Parkinson's disease were screened. Severity of motor symptoms and staging were measured with the Unified Parkinson's Disease Rating Scale (section III) and the Hoehn and Yahr scale. Audiometric evaluation consisted of a comprehensive audiologic case history and questionnaire, visual otoscopic examination, acoustic immittance measures (tympanogram and acoustic reflexes), pure tone audiometry, and measurement of brain stem auditory-evoked potentials. Healthy age- and sex-matched subjects were selected as the control group. One hundred six of 118 patients were enrolled. Pure tone audiometry revealed age-dependent high-frequency hearing loss in patients with Parkinson's disease compared with both normative values and values for healthy age- and sex-matched controls (75/106 [71%], χ(2) = 5.959, P = .02; 92/106 [86.8%] vs 60/106 [56.6%], χ(2) = 23.804, P sensorial inputs occurring over the course of illness remains to be determined. Because α-synuclein is located predominately in the efferent neuronal system within the inner ear, it could affect susceptibility to noise-induced hearing loss or presbycusis. It is feasible that the natural aging process combined with neurodegenerative changes intrinsic to Parkinson's disease might interfere with cochlear transduction mechanisms, thus anticipating presbycusis.

Full Text Available The objective of this study was to further develop the Ida Institute model on communication partners’ (CPs journey through experiences of person with hearing impairment (PHI, based on the perspectives of CPs. Nine CPs of hearing aid users participated in this study, recruited through the Swansea hearing impaired support group. Semi-structured interviews were conducted, the data were analysed using qualitative thematic analysis and presented with the use of process mapping approach. Seven main phases were identified in the CP journey which includes: (1 contemplation, (2 awareness, (3 persuasion, (4 validation, (5 rehabilitation, (6 adaptation, and (7 resolution. The Ida Institute model (based on professionals’ perspective was compared with the new template developed (based on CPs’ perspectives. The results suggest some commonalities and differences between the views of professionals and CPs. A new phase, adaptation, was identified from CPs reported experiences, which was not identified by professionals in the Ida Institute model. The CP’s journey model could be a useful tool during audiological enablement/rehabilitation sessions to promote discussion between the PHI and the CP. In addition, it can be used in the training of hearing healthcare professionals.
Full Text Available Traditionally, audiology research has focused primarily on hearing and related disorders. In recent years, however, growing interest and insight has developed into the interaction of hearing and cognition. This applies to a person’s listening and speech comprehension ability and the neural realization thereof. The present perspective extends this view to oral communication, when two or more people interact in social context. Specifically, the impact of hearing impairment and cognitive changes with age is discussed.In focus are executive functions, a group of top-down processes that guide attention, thought and action according to goals and intentions. The strategic allocation of the limited cognitive processing capacity among concurrent tasks is often effortful, especially under adverse communication conditions and in old age. Working memory, a sub-function extensively discussed in cognitive hearing science, is here put into the context of other executive and cognitive functions required for oral communication and speech comprehension. Finally, taking an ecological view on hearing impairment, activity limitations and participation restrictions are discussed regarding their psycho-social impact and third-party disability.

Noise-induced hearing loss (NIHL) is a major occupational hazard. Occupational noise exposure threatens the hearing of many workers. In addition to noise exposure in the workplace, multiple factors affect individual susceptibility to NIHL. The purpose of this study was to identify factors associated with hearing loss in airport workers. A cross-sectional epidemiological design was used. Study subjects were 255 high noise-exposed full-time male workers at a large metropolitan airport in Korea. Data were collected by a self-administered questionnaire, blood pressure measurement, audiological assessment, and a record review of baseline hearing and noise levels of locations where the employee worked. The result of multivariate analysis showed that both occupational noise exposure (noise exposure level, years of noise exposure) and personal risk factors including non-occupational noise exposure, history of ear disease, ototoxic drug use, cigarette smoking, hypertension, and use of hearing protective devices (HPDs) were significantly associated with hearing loss. An aggressive hearing conservation program is needed at the airport, emphasizing both job-related noise exposure and personal risk factors for hearing loss. PMID:12024523
Full Text Available Hearing is a key sense in human communication development and communication is the basic need for learning Speech is the best way of communication and speech development is impeded by hearing loss. Hearing loss compromises optimal development and personal achievement because language and communication serve as the foundations for learning and also normal child development delay in the acquisition of these skills affect literacy academic achievement and personal and social development. The studies show that auditory deprivation specially in critical period of the brain development (first year of life results in considerable changes in cochlear nuclei of the brain stem Therefore, early detection of hearing loss in children has been a long standing clinical priority in audiology. In this article we have reviewed 60 years effort for early detection of hearing loss and finally. emphasiz that the basic assumption of new born hearing screening is early intervention. Early detection followed by early intervention will result in near normal speech achievement in these children which meaiis personal and social independence in life. In other words early intervention maximizes the benefits the child the family and the society will receive.
The study was carried out on children born over a 10 year period from 1997 to 2006 in Kobe city and referred to our center for specialist audiological assessment. A total of 107 cases had a bilateral sensorineural hearing impairment averaging 25 dB or over in the better hearing ear during the study period. To ascertain causes of sensorineural hearing impairment, full medical histories were obtained with detailed family history relevant to hearing impairment and perinatal course for adverse etiological factors. The children were investigated for possible congenital infection and chromosomal anomalies. Children with positive family history of deafness in parents or siblings constituted 11.2% of cases (genetic group). Other etiological groups showed the following distribution: syndromal group 5.6%; inner ear anomalies 5.6%; perinatal group 13.1%; congenital infection 11.2%; chromosomal anomalies 16.8%; multiple congenital anomalies 5.6%; causes unknown 30.9%. The high incidence of causes unknown indicates that steps should be taken to yield a diagnosis. The total number of children born in Kobe city was 117,896 during the period from 1997 to 2005, which gave a prevalence rate of hearing impairment of 0.87/1,000 births. Newborn hearing screening identified many children earlier and also provide the opportunity to finetune the evaluation. (author)

Full Text Available INTRODUCTION: Auditory rehabilitation in children with bilateral severe-to-profound sensorineural hearing loss with cochlear implant has been developed in recent decades; however, the rehabilitation of children with cerebral palsy still remains a challenge to otolaryngology and speech therapy professionals. OBJECTIVE: To verify the effectiveness of cochlear implants in the development of auditory and language skills in children with cerebral palsy. METHODS: A prospective analytical study. The evaluation of auditory responses to speech test was applied to the children in this study at regular intervals following implantation. Standardized tests that assess and quantify the development of auditory and language skills were administered and speech therapy video records and speech therapy files were analyzed. All children went through individually tailored intensive audiological rehabilitation programs following cochlear implantation. RESULTS: Two participants had gradual auditory and language development when compared to other participants who reached advanced levels in hearing and oral language classifications. CONCLUSION: The use of the Cochlear implant enabled participants to reach advanced stages of hearing and language skills in three of the five participants with cerebral palsy in this study. This electronic device is a viable therapeutic option for children with cerebral palsy to help them achieve complex levels of auditory and language skills.

Gap induced pre-pulse inhibition (Gap-PPI) of acoustic startle reflex has been used as a measurement of tinnitus in animal models. However, whether this test is sensitive to detect tinnitus in humans is still unclear. Based on the testing procedure used in animal studies, a human subject testing method was formulated and conducted to investigate if a similar result could be found in tinnitus patients. Audiologic and tinnitus assessments and acoustic startle reflex measurements were performed on seven tinnitus subjects and nine age matched subjects without tinnitus. There was no significant difference found between the control and tinnitus group on the Gap-PPI across the frequencies evaluated. The amplitude of the startle response in the tinnitus group with normal hearing thresholds was significantly higher than the control group and those with tinnitus and hearing loss. This preliminary result suggests that hyperexcitability in the central auditory system may be involved in tinnitus. There was no correlation between hearing thresholds and the increased amplitude of startle response.

The recent audiological literature has put forward the hypothesis that children with unilateral hearing loss (UHL) show delays in educational achievement and academic progress and some behavioural difficulties. This motivated us to investigate the long-term effects of monaural auditory deprivation in a group of adults who had suffered from UHL since childhood. A group of subjects, ranging in age from 30 to 55 years, suffering from sensorineural UHL since early childhood, has been examined for psychosocial and psychoacoustical effects and statistically compared with a control group matched for age and sex. We prepared a questionnaire directed to provide some objective and subjective indices of psychosocial disability and handicap. Some questions were directed towards specific aspects of auditory function; others assessed the degree of education and the type of working performed. The results of the investigation confirmed the superiority of binaural v. monaural hearing. This was clearly demonstrated in psycho-acoustical performance in sound localisation, speech recognition in noise, together with the appreciation of music. On the other hand, the parameters concerned with educational, social and employment achievement did not support the existence of any significant difference between binaurally and monaurally hearing subjects. The data obtained in the present study thus do not support the existence of non-auditory, long-term effects of monaural hearing loss. PMID:3390628

Audiometry observations were analyzed for 290 irradiated survivors of the 1945 atomic bomb in Hiroshima and in 293 nonirradiated subjects. The study was undertaken in order to determine the age changes in audiology in irradiated and nonirradiated subjects as well as to investigate the pattern of hearing levels in a Japanese population for comparison with patterns in Caucasians. The following statistical observations were made. Correlation between hearing levels for right and left ear. Correlation between hearing levels at various cycles. Changes in hearing levels by age and sex. The relation between age and decibel loss was not linear and correlation ratios with age were 0.45 to 0.72. Audiometry seems to be of some value as one of a battery of tests of physiologic aging designed for detection of irradiation induced nonspecific aging acceleration. In this relatively small sample, no differences in hearing acuity were detected in the atomic bomb survivors as compared with the control sample. 6 references, 3 figures, 9 tables.
