permanent Unilateral Hearing Loss uhl and childhood development
Current Otorhinolaryngology Reports, 2018Co-Authors: Judith E. C. LieuAbstract:The aim of this study is to summarize the consequences of permanent Unilateral Hearing Loss (UHL) on the development of children as documented in the recent literature. Congenital and early-identified UHL places young children at risk for delays in speech-language development. School-aged children with UHL score lower on standardized tests of language and cognition and need increased assistance in school for educational and behavioral issues than siblings with normal Hearing, and report lower Hearing-related quality of life, similar to children with bilateral Hearing Loss (HL). Early intervention, including use of Hearing amplification devices, might ameliorate some of those affects. For a child with mild to severe UHL at presentation, the risk of progression of HL in the worse-Hearing ear may be as high as 40%, and the risk of progression to bilateral HL approaches 20%. Although UHL can adversely affect the development of children, how to mitigate those effects requires investigation.

differences in interregional brain connectivity in children with Unilateral Hearing Loss
Laryngoscope, 2017Co-Authors: Matthew E Jung, Bradley L Schlaggar, Rebecca S Coalson, Miranda Colletta, Judith E. C. LieuAbstract:Objectives To identify functional network architecture differences in the brains of children with Unilateral Hearing Loss (UHL) using resting-state functional-connectivity magnetic resonance imaging (rs-fcMRI). Study Design Prospective observational study. Methods Children (7 to 17 years of age) with severe to profound Hearing Loss in one ear, along with their normal Hearing (NH) siblings, were recruited and imaged using rs-fcMRI. Eleven children had right UHL; nine had left UHL; and 13 had normal Hearing. Forty-one brain regions of interest culled from established brain networks such as the default mode (DMN); cingulo-opercular (CON); and frontoparietal networks (FPN); as well as regions for language, phonological, and visual processing, were analyzed using regionwise correlations and conjunction analysis to determine differences in functional connectivity between the UHL and normal Hearing children. Results When compared to the NH group, children with UHL showed increased connectivity patterns between multiple networks, such as between the CON and visual processing centers. However, there were decreased, as well as aberrant connectivity patterns with the coactivation of the DMN and FPN, a relationship that usually is negatively correlated. Conclusion Children with UHL demonstrate multiple functional connectivity differences between brain networks involved with executive function, cognition, and language comprehension that may represent adaptive as well as maladaptive changes. These findings suggest that possible interventions or habilitation, beyond amplification, might be able to affect some children's requirement for additional help at school. Level of Evidence 3b.

auditory outcomes with Hearing rehabilitation in children with Unilateral Hearing Loss a systematic review
Otolaryngology-Head and Neck Surgery, 2017Co-Authors: Swathi Appachi, Judith E. C. Lieu, Michael S. Cohen, Jessica Specht, Nikhila Raol, Kavita Dedhia, Samantha AnneAbstract:Objective Options for management of Unilateral Hearing Loss (UHL) in children include conventional Hearing aids, bone-conduction Hearing devices, contralateral routing of signal (CROS) aids, and frequency-modulating (FM) systems. The objective of this study was to systematically review the current literature to characterize auditory outcomes of Hearing rehabilitation options in UHL. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to January 2016. Manual searches of bibliographies were also performed. Review Methods Studies analyzing auditory outcomes of Hearing amplification in children with UHL were included. Outcome measures included functional and objective auditory results. Two independent reviewers evaluated each abstract and article. Results Of the 249 articles identified, 12 met inclusion criteria. Seven articles solely focused on outcomes with bone-conduction Hearing devices. Outcomes favored improved pure-tone averages, speech recognition thresholds, and sound localization in implanted patients. Five studies focused on FM systems, conventional Hearing aids, or CROS Hearing aids. Limited data are available but suggest a trend toward improvement in speech perception with Hearing aids. FM systems were shown to have the most benefit for speech recognition in noise. Studies evaluating CROS Hearing aids demonstrated variable outcomes. Conclusions Data evaluating functional and objective auditory measures following Hearing amplification in children with UHL are limited. Most studies do suggest improvement in speech perception, speech recognition in noise, and sound localization with a Hearing rehabilitation device.

Speech and Language Consequences of Unilateral Hearing Loss: A Systematic Review:
Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 2017Co-Authors: Samantha Anne, Judith E. C. Lieu, Michael S. CohenAbstract:Objective Unilateral Hearing Loss has been shown to have negative consequences for speech and language development in children. The objective of this study was to systematically review the current literature to quantify the impact of Unilateral Hearing Loss on children, with the use of objective measures of speech and language. Data Sources PubMed, EMBASE, Medline, CINAHL, and Cochrane Library were searched from inception to March 2015. Manual searches of references were also completed. Review Methods All studies that described speech and language outcomes for children with Unilateral Hearing Loss were included. Outcome measures included results from any test of speech and language that evaluated or had age-standardized norms. Due to heterogeneity of the data, quantitative analysis could not be completed. Qualitative analysis was performed on the included studies. Two independent evaluators reviewed each abstract and article. Results A total of 429 studies were identified; 13 met inclusion criteria and were reviewed. Overall, 7 studies showed poorer scores on various speech and language tests, with effects more pronounced for children with severe to profound Hearing Loss. Four studies did not demonstrate any difference in testing results between patients with Unilateral Hearing Loss and those with normal Hearing. Two studies that evaluated effects on speech and language longitudinally showed initial speech problems, with improvement in scores over time. Conclusions There are inconsistent data regarding effects of Unilateral Hearing Loss on speech and language outcomes for children. The majority of recent studies suggest poorer speech and language testing results, especially for patients with severe to profound Unilateral Hearing Loss.

Unilateral Hearing Loss in youth development of candidate items for a condition specific validated instrument
Otolaryngology-Head and Neck Surgery, 2018Co-Authors: Patricia L Purcell, David L Horn, Kathleen C Y Sie, Meghan Wisneski, Todd C Edwards, Dylan K Chan, Jonathan R SkirkoAbstract:Objective This study interviewed youth with Unilateral Hearing, utilizing their responses to generate candidate items for a condition-specific patient-reported instrument. Study Design Mixed methods, cross-sectional. Setting Tertiary care children's hospital. Participants and Methods Youth with Unilateral Hearing Loss and normal Hearing in the contralateral ear were identified and recruited for participation through query of an audiometric database and through Hearing Loss clinics. Interviews with the youth were qualitatively analyzed to identify common themes and generate items related to functional impact. A multi-institutional expert panel reviewed items with prespecified item selection criteria. Participants rated items for impact on daily life. For preliminary criterion validity assessment, statistical analyses explored correlations between functional scores and type and severity of Hearing Loss. Results Thirty-nine youth aged 9 to 18 years with Unilateral Hearing Loss participated; 31% used a Hearing device. Fifteen youth participated in interviews; thematic analysis, item crafting, and expert panel item review resulted in 41 items. Twenty-six youth responded to the items, reporting low functional scores in the domains of sound localization, ear positioning, and noise environment. They reported better levels of function in carrying out group conversations, focusing on schoolwork, and feeling safe during activities. Multivariate linear regression found that youth scored 0.4 points (or approximately 8%) lower on the functional impact scale with every 20-dB HL increase in pure tone average in the abnormal ear. Conclusion Youth with Unilateral Hearing Loss report functional impact, particularly related to sound localization, ear positioning, and noise environment; therefore, they may benefit from a condition-specific functional assessment instrument.

children with Unilateral Hearing Loss may have lower intelligence quotient scores a meta analysis
Laryngoscope, 2016Co-Authors: Patricia L Purcell, Justin R Shinn, Greg E Davis, Kathleen C Y SieAbstract:Objectives/Hypothesis In this meta-analysis, we reviewed observational studies investigating differences in intelligence quotient (IQ) scores of children with Unilateral Hearing Loss compared to children with normal Hearing. Data Sources PubMed Medline, Cumulative Index to Nursing and Allied Health Literature, Embase, PsycINFO. Methods A query identified all English-language studies related to pediatric Unilateral Hearing Loss published between January 1980 and December 2014. Titles, abstracts, and articles were reviewed to identify observational studies reporting IQ scores. Results There were 261 unique titles, with 29 articles undergoing full review. Four articles were identified, which included 173 children with Unilateral Hearing Loss and 202 children with normal Hearing. Ages ranged from 6 to 18 years. Three studies were conducted in the United States and one in Mexico. All were of high quality. All studies reported full-scale IQ results; three reported verbal IQ results; and two reported performance IQ results. Children with Unilateral Hearing Loss scored 6.3 points lower on full-scale IQ, 95% confidence interval (CI) [−9.1, −3.5], P value < 0.001; and 3.8 points lower on performance IQ, 95% CI [−7.3, −0.2], P value 0.04. When investigating verbal IQ, we detected substantial heterogeneity among studies; exclusion of the outlying study resulted in significant difference in verbal IQ of 4 points, 95% CI [−7.5, −0.4], P value 0.028. Conclusions This meta-analysis suggests children with Unilateral Hearing Loss have lower full-scale and performance IQ scores than children with normal Hearing. There also may be disparity in verbal IQ scores. Laryngoscope, 126:746–754, 2016

bony cochlear nerve canal stenosis and speech discrimination in pediatric Unilateral Hearing Loss
Laryngoscope, 2015Co-Authors: Patricia L Purcell, David L Horn, Ayaka J Iwata, Grace S Phillips, Angelisa M Paladin, Kathleen C Y SieAbstract:Objectives/Hypothesis To examine the relationship between bony cochlear nerve canal (BCNC) width, degree of Hearing Loss, and speech discrimination in children with Unilateral sensorineural Hearing Loss (USNHL). Study Design Retrospective chart review (case-control study). Methods Audiometric database was cross-referenced with radiologic database at pediatric tertiary care facility to identify children with USNHL and temporal bone computed tomography. BCNC widths were measured independently by two radiologists blinded to affected ear. Regression analyses investigated associations among variables. Results One hundred and sixty children with USNHL had temporal bone imaging. Mean BCNC width was significantly smaller in affected ears, P = 0.0001. Narrower width was associated with more severe Hearing Loss, P = 0.01. Among children who had narrower cochlear nerve canals in affected ears compared to unaffected ears, smaller width was associated with lower speech discrimination score, P = 0.03. Increasing asymmetry in BCNC width between affected and unaffected ears was associated with poorer discrimination scores, P = 0.02. Among ears with asymmetrically smaller cochlear nerve canals, a 1-mm reduction in cochlear canal width between the normal and affected ear was associated with 30.4% lower word recognition score percentage in the affected ear, P = <0.001. Conclusion There is a significant association between BCNC stenosis and impaired speech discrimination, independent of degree of Hearing Loss. Further investigation is needed to determine whether BCNC stenosis is a poor prognostic factor for auditory rehabilitation. Level of Evidence 3b. Laryngoscope, 125:1691–1696, 2015

Unilateral Hearing Loss and single sided deafness in children an update on diagnosis and management
Current Otorhinolaryngology Reports, 2020Co-Authors: Patricia L Purcell, Sharon L Cushing, Blake C Papsin, Karen A GordonAbstract:This review highlights our current understanding of the impact of Unilateral Hearing Loss and single-sided deafness in children, offering insight into diagnosis and management. Children with Unilateral Hearing Loss develop an aural preference toward their better Hearing ear, leading to difficulties with spatial navigation, balance, speech/language skills, and quality of life when compared with typical Hearing peers. Cochlear nerve aplasia and cytomegalovirus are among the most common etiologies for Unilateral Hearing Loss, which has important implications for treatment. Hearing rehabilitation relies upon early correction of Hearing Loss with an appropriate auditory prosthesis. In children with single-sided deafness, cochlear implants are the only intervention that potentially offers restoration of bilateral Hearing, and studies continue to refine candidacy protocols. Unilateral Hearing Loss has important consequences for children. Recent studies emphasize the importance of early diagnosis and investigate ways to appropriately restore bilateral Hearing in these children.

amplification considerations for children with minimal or mild bilateral Hearing Loss and Unilateral Hearing Loss
Trends in Amplification, 2008Co-Authors: Sarah Mckay, Judith S Gravel, Anne Marie TharpeAbstract:Children with minimal or mild bilateral Hearing Loss and Unilateral Hearing Loss are at higher risk for academic, speech-language, and social-emotional difficulties than their normal Hearing peers. The choice to fit infants with moderate or greater degrees of bilateral Hearing Loss has been standard practice for most clinicians, but for those with minimal or mild bilateral Hearing Loss or Unilateral Hearing Loss, the fitting of Hearing technology must be based on limited data. Evidence does not yet exist to support all the management decisions that an audiologist must make upon identifying an infant with minimal or mild bilateral Hearing Loss or Unilateral Hearing Loss. It is not yet known which children are at the greatest risk for educational problems nor is it known if the provision of early amplification in this population will help a child avoid later difficulties. Some of these considerations and current Hearing technology options for children with minimal or mild bilateral Hearing Loss or Unilateral Hearing Loss are reviewed in this article.

Hearing screening and diagnostic evaluation of children with Unilateral and mild bilateral Hearing Loss
Trends in Amplification, 2008Co-Authors: Danielle S Ross, June W Holstrum, Marcus Gaffney, Denise Green, Robert F Oyler, Judith S GravelAbstract:More than 90% of newborns in the United States are now being screened for Hearing Loss. A large fraction of cases of Unilateral Hearing Loss and mild bilateral Hearing Loss are not currently identified through newborn Hearing screening. This is of concern because a preponderance of research has demonstrated that Unilateral Hearing Loss and mild bilateral Hearing Loss can lead to developmental delays and educational problems for some children. To help address this probable underidentification of Unilateral Hearing Loss and mild bilateral Hearing Loss among infants and children, the Centers for Disease Control and Prevention Early Hearing Detection and Intervention program and the Marion Downs Hearing Center convened a workshop in Breckenridge, Colorado, in July 2005. During this workshop, several issues related to screening and diagnosing Unilateral Hearing Loss and mild bilateral Hearing Loss were identified, as well as recommendations for future research in this area. Issues identified included the lack of standardized definitions for permanent Unilateral Hearing Loss and mild bilateral Hearing Loss; the use of screening protocols that are primarily designed to identify bilateral and Unilateral Hearing Losses of a moderate degree or greater (eg, above 40 dB); calibration of screening equipment; availability of facilities that can provide the full range of audiologic, diagnostic, and management services to this pediatric population; and an overall lack of awareness by many professionals and families about the potential effect of Unilateral Hearing Loss and mild bilateral Hearing Loss. Suggestions for future research, such as identifying ways to improve the identification of cases of Unilateral Hearing Loss and mild bilateral Hearing Loss, were also discussed.

early intervention for children with Unilateral and mild bilateral degrees of Hearing Loss
Trends in Amplification, 2008Co-Authors: June W Holstrum, Judith S Gravel, Marcus Gaffney, Robert F Oyler, Danielle S RossAbstract:Some children with Unilateral Hearing Loss or mild bilateral Hearing Loss are at risk for developmental delays, educational difficulties, and other adverse effects. However, these children face several challenges in receiving services that can prevent such problems. Many do not meet existing eligibility requirements for early intervention services in their state. Information disseminated to professionals and parents often does not convey the significance of Unilateral and mild bilateral Hearing Loss. Some professionals indicate that there are insufficient guidelines defining appropriate intervention services for these children. Factors that influence developmental outcomes in this population are not well understood, making it difficult to determine which children can benefit from intervention services. Additional data are needed about how to minimize or prevent adverse outcomes in these children. This article presents suggestions for intervention and future research that were developed by participants of the 2005 National Workshop on Mild and Unilateral Hearing Loss.
