Abstract:
The Acceptable Noise Level (ANL) has received substantial attention due to its potential to predict hearing-aid use success. It is a subjective measure of patients’ willingness to tolerate noise, while listening to speech at the most comfortable level. Previous research suggests no relationship between ANLs and objective speech recognition performance in noise for hearing-impaired listeners. However, the relationship between self-rated speech intelligibility and ANL is unknown.
Forty-six hearing-impaired listeners and twenty normal-hearing listeners participated in the study. The ANLs were measured by Quick Speech-in-Noise (QuickSIN) test sentences in a four-talker babble. The self-rated speech intelligibility and the objective speech recognition performance were both measured, using the same test format and materials from the QuickSIN protocol. The differences between the rating of intelligibility and objective measures reflect how accurately listeners can judge their ability to listen in noise. Pearson correlation was used for the data analysis. The data revealed a significantly moderate correlation (r = 0.6, p < .0001) between ANLs and self-rated speech intelligibility for hearing-impaired listeners and a weak but significant correlation of 0.4 for the normal-hearing listeners (p = .04). No relationship was found between ANLs and the discrepancy of objective and subjective speech recognition performance for either group. The results indicated that listeners who rated themselves as highly able to listen to speech in noise were better able to tolerate noise than those who rated themselves as less able to listen in noise.

Abstract:
OBJECTIVE: Ossicular discontinuity may result from chronic otitis media and usually detected intra-operatively. Our objective is to determine if preoperative audiogram could predict preoperatively the presence of ossicular discontinuity.
METHODS: A prospective cohort study was run on patients aged 12 to 75 operated for non-cholesteatomous chronic otitis media. Pre-operative audiogram was analyzed to measure frequency specific air-bone gap (ABG) cut-off values. Intraoperatively, ossicular chain integrity was carefully checked. Logistic regression analysis was done to have a predictive model.
RESULTS: 270 patients (306 ears) were included. Frequency specific ABG cut-off values can predict ossicular discontinuity, namely: high ABGs at 1000 Hz (>27.5dB) and 2000 Hz (>17.5dB) are the most reliable variables associated with ossicular discontinuity.
CONCLUSION: Preoperative audiograms can predict presence of ossicular discontinuity in chronic suppurative otitis media.

Abstract:
Objectives. Otitis media with effusion is characterized with conductive hearing (CHL) loss which affects a child’s ability to recognize and memorize spoken language and develop auditory working memory. The aim of the study was to find out; if peripheral hearing deficit cause speech recognition disorders, possible difference in speech recognition while hear binaurally vs. monaurally for left and right ear respectively, possible gender and ear side dependence.
Method: Clinical randomized study included right-handed 48 girls and 95 boys (mean age of 6y) tested in age subgroups; 4-7, 8-12 years, with OME and CHL and no previous otologic surgeries. Tonal audiometry estimated medians of left and right ears (M) for 500Hz,1000Hz,2000Hz,4000Hz and average hearing level for speech frequencies (AHL) and speech audiometry score (SDS) measured threshold of speech recognition while hear binaurally in free sound field and through the left or right ear respectively by headphones. All of the children undergo speech and language screening tests.
Results: Tonal audiometry showed MAHL on left ears (24.3dB) girls higher than on right ears (21.9 dB) and also higher than on of left (20.6 dB) and right ears (20.5 dB) in boys. Boys show no difference in average of AHL between left vs. right ears. Girls showed higher (M) mean for 500Hz (26.7dB) and 2000Hz (mean, 20.5dB) on left (21.8dB) ears than on their right (20.5dB) ears and both ear sides in boys. Girls have speech recognition threshold (20.8dB) and score of 100% (46.2dB) recognition on higher level than boys (13.6dB and 36.8dB). The worst score for speech threshold and 100% of recognition reach test by headphones on left ears in girls.
Conclusions: More severe CHL for restrictive frequencies particularly for 4000Hz caused more speech recognition disturbances in girls than boys and starts at earlier age. Boys have higher frequency of OME but smaller rate of disorders of speech discrimination at preschool age and less severe CHL and SDS damage than girls. Girls CHL showed left side lateralization of peripheral hearing loss for higher frequencies which correlate with lateralization of central auditory processing.

Title: Influence of the central auditory disorders on behavior in children with hearing loss connected to otitis media with effusion
Biography:
Jasenka Broz Frajtag is a Professor of speech pathologist in University Clinical Hospital Centre, Zagreb, Department of Otorhinolaryngology Center for Audiology and Vestibulology in Croatia. Currently she is studying in Medical school Public Health. Work rehabilitation with children and adults who have hearing problems, wear hearing aid/s or cochlear implants and also having problems in speech and language. She has many publications and has delivered talks in international conferences.
Abstract:
Introduction: Otitis media with effusion is desease in the middle ear with no sign of inflamation and common cause of hearing loss worldwide and most common health problem in pre-school and school age. Conductive hearing loss adversely may affect acustic binaural, sound localization, speech perception in noise, impear early language acquisition, behaviour and vertigo. The aim of the study is to exame whether otitis media with effusion and association hearing loss are related to the language development, academic achievement and behavior.
Method: Participants were thirty-nine- average olds distributed among groups according to gender and age group. The diagnostic process included tonal audiometry, tympanometry and speech audiometry ( discrimination of speech) which were performed repetitively every 7 days during the 6 weeks.
Results: Bilateral conductive hearing loss and tympanograms of B type were present in all tested children. At the age up to 7 years equal number of female and male have speech disorders (mostly articulation) and lack of concentration to the sound in general, speech and events around. At the age of 8 years or higher were much more male than female dominated cognition disorders, behavior problems, learning disabilities and problems with social adaptation. Children in general have more readiness skills in literacy (verbal problems) and math, and lower scoring in recognizing of incomplete words at school age from 8 to older ages. Male children have more learning and behavior disabilities at school age than females. Psychological problems become directly or indirectly in all cases hearing damage included children with speech language pathology. Problems with attention, hard learn, weakly concentration, untidy handwriting, missed some important information and reduced productivity in school activities.
Conclusion: Our results suggested that such structural pathoanathomical changes have more hearing loss impact on left side ears. At least in conductive hearing loss this children have disorders in hearing, verbal expressing, problems in speech, behavior (hiperactivity).
The goal is to intervene before the child is six month. Early rehabilitation for that children is much better and quality in earlier age than afterward.

Title: Pediatric Conducitve Hearing Loss, it’s Not All Fluid
Biography:
Stephen Newton completed his MD at Howard University where he graduated with honors. He then completed his residency in Otolaryngology at the University of Iowa and also performed a two year research postdoctoral fellowship looking at microRNAs and their role in hearing loss. Later, he did a clinical fellowship in Pediatric Otolaryngology at Boston Children’s Hospital. Currently Stephen is a Pediatric Otolaryngologist with Children’s Hospital of Colorado and an assistant professor in the Department of Otlaryngology at the University of Colorado. He heads the cochlear implant program at Children’s Hospital of Colorado’s extension in Colorado Springs.
Abstract:
The most common cause for conductive hearing loss in children is a middle ear effusion. However, there can be other causes, both congenital and acquired, that may require intervention beyond observation or pressure equalization tubes. Further evaluation is often required to define these types of hearing loss but an auditory history and audiogram may be the first clue. Congenital abnormalities of the ossicles and middle ear space may be suggested based on the level of hearing loss and tympanogram. These may be amenable to surgical procedure that may obviate the need for hearing aids. On the other hand, acquired and congenital cholesteatomas, can present in a multitude of ways and if not identified can lead to destruction of the ossicles and the potential for permanent hearing loss. Lastly, previous surgical intervention may alter the appearance of audiometric testing. The goal of the talk is to review the various types of conductive hearing loss in children and how they might present to the audiologist and on an audiogram.

Title: Effect of implant age on auditory ability of infants in the first year after cochlear implantation
Biography:
Dr. Hua Zhang, has got three the National Natural Science funds, a central health research project, and the Beijing Natural Science Found. The main research directions are clinical audiology and otology, especially in evaluation of cochlear implant and hearing aid, development of speech audiometry, hearing diagnosis research. He has engaged in clinical otology and audiology for more than 30 years.
Abstract:
At present, more than 90 % of cochlear implant (CI) recipients are children in China. Nowadays the implanting age is getting younger and younger. However, whether a infant less than twelve-month should be implanted immediately after diagnosis of hearing loss or not?
The most used auditory assessment questionnaires for hearing impaired infants in China are categories of auditory performance (CAP) and Infant-Toddler meaningful auditory integration scale (IT-MAIS). The former had no age distinction and no significance in short term. Some studies have indicated that the reliability of IT-MAIS is inexact. Is there any other questionnaire that can make up for the shortages?
Objective: To observe the auditory development of infants with CI between the ages of 8~24 months in the first year. The effect of implant age and intervention periods were analyzed.
Method: Based on different implant ages, 41 infants with CI were divided into group A (≤12months), group B (13-18 months), group C (19-24months), using LittlEARS Auditory Questionnaire to assess and analyze auditory development before switch-on and 3 months,6 months,9 months and 12 months after switch-on.
Results: Auditory ability was no significant difference among three groups at the same period. Significant differences were obtained among different switch-on stages.
Conclusion: Auditory abilities of infants after switch-on in the first year were significantly increased. Auditory abilities of infants before age of 24 months with CI were no difference at the same period in the first year. It is suggested that infants implanted before age of 24 months could wear hearing aids. This could establish hearing experience for children to increase the probability of hearing response and the parents’ confidence on rehabilitation. At the same time, the experience establishes a link between parents and therapists..

Professor Dr. Hossam Abdelghaffar has completed his MD degree in Audiology at the age of 30 years from Cairo University School of Medicine . He was director of Audilogy Unit at Dr. Soliman Fakeeh Hospital in Kingdom of Saudia Arabia from 2003-2005 .Now he is holding the position of professor of Audilogy and Head of OtoRhinoLaryngology department at School of Medicine Helwan University ,Cairo ,Egypt He has published more than 15 papers in reputed journals and he is reviewer of the Egyptian Journal of Ear, Nose, Throat and Allied Sciences . He has supervised more than 20 Master and Doctorate degree thesis . He is a member of the International Association of Physicians in Audiology (IAPA)
Abstract:
To study the incidence of congenital hearing impairment in the Saudi population and to evaluate the need of establishing a Saudi universal neonatal hearing screening program based on transient evoked otoacoustic emission. A total of 11986 well non-high-risk neonates were screened by transient evoked otoacoustic emission over period of 8 years from September 1996 to February 2004. The universal hearing screening was consequently done in a daily base before discharge from nursery. Those who failed the initial screening were followed up diagnostically until hearing loss was confirmed or excluded. From the total number of 11,986 neonates (41.4% male and 58.6% females) examined in this study 10943 (91.3%) neonates passed the first screening step while 1043(8.7%) neonates failed. From the 1043 neonates examined in the second screening step in the 5th day of life, 300 (29%) neonates failed. At the age of 5 months, all the 300 infants that failed the second screening step underwent a comprehensive audiological assessment to confirm the existence of hearing loss. The 278 infants that passed the assessment were considered as normal; while 22 failed and were confirmed to have congenital hearing loss. Of these 22 infants, 2 had unilateral sensorineural hearing loss, and the remaining 20 had bilateral sensorineural hearing loss. The incidence of sensorineural hearing loss was estimated to be 0.18% while the incidence of bilateral sensorineural hearing loss was 0.17%. No significant difference between males and females was found. The average age at confirmation of congenital hearing loss was 5.5 months. The incidence of congenital hearing loss in the western region of Saudi Arabia is relatively high compared with international figures. Hearing screening for all neonates using transient evoked otoacoustic emission should be part of the standard medical care in Saudi Arabia

Title: Ion channels regulate biophysical specializations in the auditory brainstem
Biography:
Dr. Sanchez earned a PhD in auditory neuroscience from Kent State, a master’s degree in audiology from Michigan State and a bachelor’s degree in communication sciences and disorders from Northern Colorado. He’s clinically trained in audiology from the Cleveland Clinic and completed postdoctoral training in developmental auditory neurobiology at the University of Washington. As director of the Central Auditory Physiology Laboratory at Northwestern, his research investigates developmental mechanisms underlying ion channel and synaptic receptor function. Such biophysical properties may guide requirements for cochlear implant and hearing aid design and potentially provide pharmacological targets to improve disorders of the auditory system.
Abstract:
Ultrafast and temporally precise action potentials are biophysical specializations of auditory brainstem neurons; properties necessary for encoding sound localization and communication cues. Fundamental to this are voltage dependent potassium and sodium ion channels. In this presentation, I will report our recent findings on how these ion channels shape action potential properties in the developing auditory brainstem. Using patch-â€clamp recordings from individual cochlear nucleus neurons, our results indicate that the refinement of active ion channel properties operate differentially in order to develop action potential specializations. Such differential regulation promotes the firing of fast, reliable and phased-â€locked action potentials at relatively high rates of afferent stimulation, a biophysical property required for normal auditory information processing. Developmental changes in ion channel subunit content were the largest contributor to this process and blockade of specific ion channel function resulted in aberrant neuronal excitability and action potential control. The idea that the regulation of ion channel properties is a critical mechanism underlying auditory pathophysiological conditions will also be discussed.

Abstract:
Objectives: To describe a modified technique of titanium prosthesis stabilization in ossicular chain reconstruction during mastoidectomy, and to evaluate the outcome of this technique.
Methods: A retrospective study done at a tertiary referral institute Included 133 cases of all ossiculoplasties performed between August 2013 and August 2015. We are suggesting a new technique for ossiculoplasties mechanical stability using Vario Kurz titanium prostheses by: partial ossicular replacement prosthesis (PORP) is crimped on the head of stapes and total ossicular replacement prosthesis (TORP) is coupled to the footplate by cartilage shoe. Both prostheses were coupled to the drum by embedding a pin on the headpl ate of prosthesis in a full thickness broad cartilage palisades graft. After packing of the ear canal, the stability of reconstruction was checked using 30 degree scope placed in the mastoid. Preoperative and postoperative audiometric evaluation using air-bone gap were assessed. Results are compared with historical control groups.
Results: The study included 133 patients, of which 88 underwent PORP reconstruction and 45 underwent TORP reconstruction. Mean follow-up was 14 months. A postoperative air-bone gap (ABG)≤20 dB was obtained in 83 % of the patients ( 89% for PORP, and 71% for TORP).
Conclusions: A robust prosthesis stability leads to a better ossicular coupling and more satisfactory hearing outcome compared to conventional techniques

Since 2005, I am member of the National Group of Cochlear Implant, where I investigate about Brain Plasticity in deaf and deafblind children with neurophysiological techniques and fMRI. Also, I am working in Intraoperative Neurophysiological Monitoring and attend the patients in intensive care unit
Abstract:
The cochlear implants are given the opportunity to gain the sense of hearing to deaf subject. Little is known the role of plasticity as a means to reactivate brain function.
Objective: To evaluate on plasticity before and after Cochlear Implants (CI).
Methods: evaluation of the maps topography of Visual (VEP), Somatosensory by stimulation of median (SEP-N20) and tibial (SEP-P40) nerves. We evaluated the Cortical Auditory (CAEP) and Electroencephalography (EEG) in deaf (n=18) and deafblind (n=12) pre-lingual.
Results: Topographic distribution maps of the SSEP-N20 showed expansion of activation, the over-representation was less extensive in deaf (area temporal) that in deafblind children (areas temporal and occipital). SEP-P40 no showed changed -strictly localized in area of -somesthetic information representation of the foot. The VEP no showed significant changes in deaf. Also offered for the first time, evidence of Cross-Modal-Plasticity through a study Post-IC, where deaf and deafblind children who are implanted after 7 years of age if there are changes in the SEP-N20 and the functional connectivity measured with EEG. While that with the CAEP was possible to evidence the cortical activation by the auditory sensory input through the CI.
Conclusions: The high functional connectivity after implantation and the changes in the SEP-N20 to the left temporal region in deaf and deafblind children with 7 o more age was interpreted as evidence of Cross-Modal-Plasticity, effect that may to have the use of the hands for communication in these children, with consequent implications to the optimal use of the CI during rehabilitation auditory.

Title: The Relationship between Practical Hearing Aid Skills and Patient Satisfaction in the public health care setting in South Africa
Biography:
Tracy Wentzel has completed her masters at the age of 30 years from University of the Witwatersrand, South Africa. She currently works at Helen Joseph Hospital within the public health care setting in South Africa. She is passionate about hearing aids and ensuring a patient centred approach to hearing aid fittings in order to ensure positive outcomes.
Abstract:
The ability to handle a hearing aid may impact on satisfaction with and acceptance of hearing aids by individuals with hearing loss. There is evidence of the correlation between hearing aid handling skills and effective hearing aid use. Although many studies have focused on the individuals’ satisfaction with their hearing aids there is a lack of information regarding the relationship between satisfaction with hearing aids and hearing aid handling skills. This is especially true for the South African context, where no studies have been conducted to explore this relationship. The main aim of the study was thus to determine the relationship between the ability to manipulate hearing aids and self-perceived satisfaction with hearing aids in individuals fitted with hearing aids in a public health care hospital.
A non-experimental, cross-sectional, correlational research design was employed for the purpose of this study. The sample included 85 adults fitted with hearing aids in a public health care hospital. There was an equal distribution of gender and the mean age of participants was 66.27 years. Participants completed the Practical Hearing Aid Skills Test – Revised (PHAST-R) version and the Satisfaction with Amplification in Daily Life (SADL) questionnaire.
The findings of the study indicate that the majority of participants were able to successfully manipulate their hearing aids (Mean score: 75.43%; Range: 10.71 - 100; SD: 21.58). The mean global score for satisfaction with amplification was 5.2 (Range: 3.1 - 6.8; SD: 0.84) indicating high levels of satisfaction with their hearing aids. Overall there was a significant correlation between hearing aid handling skills and satisfaction with amplification (rs= 0.22871; n = 85).
The findings suggest that the majority of participants were satisfied with the hearing aids provided in a public health care hospital and that they were able to successfully handle their hearing aids. The use of the PHAST-R as part of the hearing aid orientation session is encouraged especially in light of the poor return rate for follow-up hearing aid orientation sessions at this public health care settings. The development of standard operating procedures for hearing aid fitting and orientation in the public health care sector is recommended to ensure that the best possible outcomes are ensured for all patients.
