Demographic data, referral patterns and interventions used for children and adolescents with tinnitus and hyperacusis in Denmark

Tinnitus in Children

This perspective reviews the current state of the art and literature on tinnitus in children, prevalence and risk factors, clinical management, and future priorities for healthcare provision and research. Most research in the field to date appears to be prevalence studies, which have reached dramatically different estimates; this reflects the lack of a standard language when asking about the presence of tinnitus, or how bothersome, distressing, or negatively impacting it is for the child. Estimates are also likely affected by a lack of awareness of tinnitus amongst children and parents. Children are less likely to spontaneously report tinnitus than adults, and parents are often unaware their child could even develop tinnitus, considering it a disease of older age for example. It is critical that children are asked and learn about tinnitus. In hearing clinics, clinicians should routinely ask about all children about tinnitus and offer tinnitus care and settings that are child- and family-friendly. As well as asking directly, clinicians should be alert to soft signs of tinnitus such as unexplained listening, speech perception, concentration difficulties, worry or anxiety, or difficulties completing hearing tests or using hearing aids. The recently developed impact of Tinnitus in Children Questionnaire (iTICQ) can then be used to assess problems that are most commonly core to children's experience of tinnitus. Clinical guidelines for tinnitus in children are few but provide recommendations for additional paediatric questionnaires and alternative assessments and for a range of treatment options. Of note, however, is the lack of clinical trials and, therefore, evidence of the effectiveness of any treatment for tinnitus in children. Significant and concerted work is therefore needed to raise awareness of tinnitus in children, understand the scale of clinical need, and standardise and evaluate clinical management options.

Functional Connectivity Alterations and Molecular Characterization of the Anterior Cingulate Cortex in Tinnitus Pathology without Hearing Loss

Compared with individuals with hearing loss, tinnitus patients without hearing loss have more psychological or emotional problems. Tinnitus is closely associated to abnormal metabolism and function of the limbic system, a key brain region for emotion experience, but the underlying molecular mechanism remains unknown. Using whole-brain microvasculature dynamics imaging, the anterior cingulate cortex (ACC) is identified as a key brain region of limbic system involve in the onset of salicylate-induced tinnitus in mice. In the tinnitus group, there is enhanced purine metabolism, oxidative phosphorylation, and a distinct pattern of phosphorylation in glutamatergic synaptic pathway according to the metabolome profiles, quantitative proteomic, and phosphoproteomic data of mice ACC tissue. Electroencephalogram in tinnitus patients with normal hearing thresholds show that the functional connectivity between pregenual anterior cingulate cortex and the primary auditory cortex is significantly increased for high-gamma frequency band, which is positively correlated with the serum glutamate level. These findings indicate that ACC plays an important role in the pathophysiology of tinnitus by interacting with the primary auditory cortex and provide potential molecular targets in the ACC for tinnitus treatment.

Improving Audiology Student Training by Clinical Simulation of Tinnitus: A Glimpse of the Lived Experience of Tinnitus

PURPOSE

Student audiology training in tinnitus evaluation and management is heterogeneous and has been found to be insufficient. We designed a new clinical simulation laboratory for training students on psychoacoustic measurements of tinnitus: one student plays the role of the tinnitus patient, wearing a device producing a sound like tinnitus on one ear, while another student plays the role of the audiologist, evaluating their condition. The objective of the study was to test this new clinical simulation laboratory of tinnitus from the perspective of the students.

METHOD

This study reports the findings from twenty-one audiology students (20 female and 1 male, mean age = 29, SD = 7.7) who participated in this laboratory for a mandatory audiology class at the Laval University of Quebec. Three students had hearing loss (one mild, two moderate). All students played the role of both the clinician and the patient, alternately. They also had to fill out a questionnaire about their overall experience of the laboratory.

RESULTS

The qualitative analysis revealed three main themes: "Benefits of the laboratory on future practice", "Barriers and facilitators of the psychoacoustic assessment", and "Awareness of living with tinnitus". The participants reported that this experience would have a positive impact on their ability to manage tinnitus patients in their future career.

CONCLUSION

This fast, cheap, and effective clinical simulation method could be used by audiology and other healthcare educators to strengthen students' skills and confidence in tinnitus evaluation and management. The protocol is made available to all interested parties.

Prevalence of Hyperacusis in the General and Special Populations: A Scoping Review

Objectives: To study the prevalence of hyperacusis in the general population and the special population, and to determine the effect of population differences on hyperacusis.

Methods: The two authors followed a scoping review methodology and screened nearly 30 years of English literature in Pubmed, Web of Science, OVID, and EBSCO. Then, the extracted results of each study were discussed in groups and subgroups.

Results: The authors selected 42 pieces of scientific literature that met the requirements, studying a total of 34,796 subjects, including the general population (28,425 subjects), the special occupation population (2,746 subjects), and the patients with concomitant diseases (5,093 subjects). The prevalence was 0.2–17.2% in the general population, 3.8–67% in the special occupation population, and 4.7–95% in the patients with special diseases. It was found that in the general population, the high prevalence occurs in adolescents and older adults. The prevalence of hyperacusis in women is significantly higher than in men. In people with hearing disorders, the prevalence of hyperacusis is significantly higher than in people with normal hearing. Various diseases (such as Williams syndrome, tinnitus, and autism), as well as various occupations (musicians, music students, teachers, and others), have been found to be high risk factors for hyperacusis.

Conclusion: The high prevalence of hyperacusis and the large differences between reported prevalence in different studies deserves our great attention. Additionally, in order to increase the comparability of the studies, a standardized set of criteria are needed to study the prevalence of hyperacusis.

Reflections on How Tinnitus Impacts the Lives of Children and Adolescents

Objectives The aim of this study was to generate a conceptual framework describing which aspects of children and adolescents' lives are affected by chronic tinnitus. Design Views and experiences of 32 participants from two participant groups informed this study: (a) a tinnitus group, consisting of adults who had experienced tinnitus during childhood and/or adolescence and primary carers of children/adolescents with tinnitus, and (b) a clinicians' group, consisting of clinicians who provided care for children/adolescents with tinnitus. Participants produced statements describing aspects of children/adolescents' lives that may be affected by chronic tinnitus. Key concepts were identified through the processes of sorting the statements and rating them for degree of associated impact. Result Participants identified 118 unique aspects of the lives of children/adolescents who may be affected by chronic tinnitus. These were clustered into four concepts: (a) emotional well-being, (b) academic performances, (c) social/relationa, and (d) auditory/cognitive processing. At a group level, participants rated the impact of tinnitus as above a slight degree but below a moderate degree of impact. However, individual participant's ratings indicated a range of perceived impact for each statement. Conclusions The experience of chronic tinnitus during childhood and adolescence extends beyond the mere perception of sound. The perception of tinnitus may impact a child's emotional well-being, academic performances, social/relational, and auditory/cognitive processing. The impact of tinnitus in one aspect of a child's life may influence other aspects of their life. While at a group level, participants regarded the impact of tinnitus as "somewhat more than mild" to "less than moderate"; individual participant's ratings indicate that the impact from chronic tinnitus may be highly individual and highlighted the importance of individual assessment and management. Clinically, tinnitus management during childhood and adolescence may be improved if clinicians consider the impact and manifestation of tinnitus within each child's daily life and tailor tinnitus education and management strategies accordingly.

A Cross-Sectional Study of the Prevalence and Factors Associated With Tinnitus and/or Hyperacusis in Children

Objectives:

The aim of this study was to determine the prevalence of tinnitus and/or hyperacusis in Danish children aged 10 to 16 years, and to assess associations between tinnitus or hyperacusis and other relevant factors.

Design:

A cross-sectional study based on a previously established child cohort. A total of 501 children were enrolled in the project. The study was performed in eight mainstream schools and data were collected during an 8-week period from October 27, 2014 to December 16, 2014.

Results:

Using broad tinnitus research questions, the prevalence of any tinnitus was 66.9%; of noise-induced tinnitus (NIT) was 35.7%; and of spontaneous tinnitus (ST) was 53.7%. Bothersome tinnitus was reported by 34.6% of the children with any tinnitus, 23.2% of the whole population. Few children were severely bothered (2.4%, 1.6%, respectively). It was significantly more common for children with NIT to report tinnitus episodes lasting for minutes or longer than for children with ST (p = 0.01). Girls were more likely than boys to be bothered by tinnitus [Odds ratio (OR) = 2.96; 95% confidence interval (CI) 1.34 to 6.51; p = 0.01]. 14.6% of the children reported hyperacusis, and 72.6% of those reporting hyperacusis were bothered by it, 10.6% of the whole population. The odds of having hyperacusis were 4.73 (1.57, 14.21) times higher among those with ST compared with those without ST. Furthermore, hyperacusis was associated with sound avoidance behaviors such as experience of sound-induced pain in the ear (OR = 2.95, 95% CI 1.65 to 5.27; p < 0.001), withdrawal from places or activities (OR = 3.33; 95% CI 1.44 to 7.69; p = 0.01), or concerns about sound could damage the hearing (OR = 1.85, 95% CI 1.06 to 3.31; p = 0.03).

Conclusions:

Tinnitus and hyperacusis are common in children but prevalence is dependent on tinnitus definitions. Only a few children are severely bothered by tinnitus. In the case of hyperacusis, children may exhibit sound avoidance behavior.

Reducing the Impact of Tinnitus on Children and Adolescents' Lives: A Mixed-Methods Concept Mapping Study

OBJECTIVES

To generate a conceptual framework describing what is done to reduce the impact of chronic tinnitus on the lives of children and adolescents.

DESIGN

Views and experiences of 32 adults from two participant groups informed this concept mapping study: (i) a tinnitus group (adults who experienced tinnitus during childhood/adolescence, and primary carers of children/adolescents with tinnitus) and (ii) a clinicians' group (clinicians who provided care for children/adolescents with tinnitus). Participants produced statements describing what is done to reduce the impact of chronic tinnitus on the lives of children and adolescents who experience it. Through grouping and rating processes, they identified key concepts and inferred their associated benefit.

RESULTS

The participants generated 102 unique statements across four concepts: (1) Education, Support, and Counselling; (2) Support from Parents and Teachers; (3) Clinical Assessments and Management; and (4) Self-Management Techniques. Many statements highlighted the need for child-friendly and patient-centred care. Adults with personal experience of childhood tinnitus tended to perceive many of the statements as more beneficial than did the clinician group.

CONCLUSIONS

Although many children will develop management strategies to assist them with their tinnitus, both the adults who experienced tinnitus as children and their parents valued strategies involving clinical care, knowledge, and expertise. Participants from the tinnitus group perceived a greater degree of benefit associated with strategies from all four clusters than the clinicians' group. However, both groups perceived the greatest degree of benefit as being associated with activities and strategies within the Education, Support, and Counselling and the Clinical Assessments and Management clusters. Both groups identified that recognising the occurrence of tinnitus for children and adolescents, acknowledging the potential for associated distress, and initiating clinical care provide the nexus of effective management. Addressing the concerns and needs of parents was also perceived as valuable; hence, approaching the management of tinnitus during childhood and adolescence from a family-centred care framework is recommended.

Prevalence of Decreased Sound Tolerance (Hyperacusis) in Individuals With Autism Spectrum Disorder: A Meta-Analysis

OBJECTIVES

Hyperacusis, defined as decreased tolerance to sound at levels that would not trouble most individuals, is frequently observed in individuals with autism spectrum disorder (ASD). Despite the functional impairment attributable to hyperacusis, little is known about its prevalence or natural history in the ASD population. The objective of this study was to conduct a systematic review and meta-analysis estimating the current and lifetime prevalence of hyperacusis in children, adolescents, and adults with ASD. By precisely estimating the burden of hyperacusis in the ASD population, the present study aims to enhance recognition of this particular symptom of ASD and highlight the need for additional research into the causes, prevention, and treatment of hyperacusis in persons on the spectrum.

DESIGN

We searched PubMed and ProQuest to identify peer-reviewed articles published in English after January 1993. We additionally performed targeted searches of Google Scholar and the gray literature, including studies published through May 2020. Eligible studies included at least 20 individuals with diagnosed ASD of any age and reported data from which the proportion of ASD individuals with current and/or lifetime hyperacusis could be derived. To account for multiple prevalence estimates derived from the same samples, we utilized three-level Bayesian random-effects meta-analyses to estimate the current and lifetime prevalence of hyperacusis. Bayesian meta-regression was used to assess potential moderators of current hyperacusis prevalence. To reduce heterogeneity due to varying definitions of hyperacusis, we performed a sensitivity analysis on the subset of studies that ascertained hyperacusis status using the Autism Diagnostic Interview-Revised (ADI-R), a structured parent interview.

RESULTS

A total of 7783 nonduplicate articles were screened, of which 67 were included in the review and synthesis. Hyperacusis status was ascertained in multiple ways across studies, with 60 articles employing interviews or questionnaires and seven using behavioral observations or objective measures. The mean (range) age of samples in the included studies was 7.88 years (1.00 to 34.89 years). The meta-analysis of interview/questionnaire measures (k(3) = 103, nASD = 13,093) estimated the current and lifetime prevalence of hyperacusis in ASD to be 41.42% (95% CrI, 37.23 to 45.84%) and 60.58% (50.37 to 69.76%), respectively. A sensitivity analysis restricted to prevalence estimates derived from the ADI-R (k(3) = 25, nASD = 5028) produced similar values. The estimate of current hyperacusis prevalence using objective/observational measures (k(3) = 8, nASD = 488) was 27.30% (14.92 to 46.31%). Heterogeneity in the full sample of interview/questionnaire measures was substantial but not significantly explained by any tested moderator. However, prevalence increased sharply with increasing age in studies using the ADI-R (BF10 = 93.10, R2Het = 0.692).

CONCLUSIONS

In this meta-analysis, we found a high prevalence of current and lifetime hyperacusis in individuals with ASD, with a majority of individuals on the autism spectrum experiencing hyperacusis at some point in their lives. The high prevalence of hyperacusis in individuals with ASD across the lifespan highlights the need for further research on sound tolerance in this population and the development of services and/or interventions to reduce the burden of this common symptom.

Association of Tinnitus with Depression in a Normal Hearing Population

Background and Objectives: The relationship between depression in tinnitus patients without hearing loss remains elusive. This study aimed to investigate the association between tinnitus and normal hearing and depression. Materials and Methods: Participants aged ≥12 years with normal hearing levels were recruited from the Korea National Health and Nutrition Examination Survey (KNHANES), 2009-2012. Participants with normal hearing were divided into the tinnitus and non-tinnitus groups. The relationship between tinnitus with normal hearing and variables including age, sex, depression, ischemic heart diseases, stroke, diabetes, hypertension, dyslipidemia, chronic renal disease, noise exposure, and depression were analyzed. The odds of depression for tinnitus with normal hearing were estimated using multiple logistic regression tests with complex sampling. Results: The results showed that 4.9% (107/2221) and 2.8% (290/10,316) of participants in the tinnitus group and the non-tinnitus group, respectively, experienced depression (p < 0.001). Sex, ischemic heart disease, dyslipidemia, noise exposure, and depression were positively related to tinnitus with normal hearing. The odds ratio of depression for tinnitus with normal hearing were 1.89 (95% CI 1.37-2.60, p < 0.001). Conclusions: Tinnitus with normal hearing was related to the female sex, ischemic heart disease, dyslipidemia, noise exposure, and depression. Depression had the highest odds of tinnitus with normal hearing.

Reflections and perceptions of chronic tinnitus during childhood and adolescence

OBJECTIVES

To enhance understanding of the lived experience of tinnitus during childhood/adolescence from the reflections of adults who experienced tinnitus during childhood/adolescence and the perceptions of primary carers and clinicians who care for children/adolescents who experience it. Secondly to develop a conceptual framework to better describe the experience of chronic tinnitus during childhood/adolescence and to guide approaches to assessment and management.

DESIGN

Using a concept mapping approach, participants from two stakeholder groups generated statements describing what chronic tinnitus sounds and feels like to children/adolescents who experience it. Participants subsequently grouped and rated the statements to reveal key concepts. The first stakeholder group consisted of adults who had experienced chronic tinnitus as a child/adolescent and parents of children or adolescents who are experience chronic tinnitus. The second stakeholder group consisted of clinical professionals who provide care for children/adolescents experiencing chronic tinnitus.

RESULTS

Participants identified 102 different descriptions of what chronic tinnitus sounds and feels like to children/adolescents, across five concepts: 1) Sounds of tinnitus; 2) Descriptions of tinnitus; 3) Perceptions of tinnitus; 4) Emotional responses to tinnitus and 5) Physical responses to tinnitus.

CONCLUSIONS

The experience of chronic tinnitus during childhood/adolescence is heterogenous and multifaceted. It may involve the perception of sound, emotions and physiological sequalae. How a child/adolescent experiences their tinnitus will be influenced by the interplay between the sound they perceive, the number of accompanying senses involved and their interpretation of the sound. As well as the emotions and physical effects they experience.

Hyperacusis in children: a scoping review

Background

Hyperacusis is a chronic condition commonly defined as a lowered tolerance or increased sensitivity to everyday environmental sounds. It has been viewed as a paediatric disorder which can cause significant impairment to a child’s normal functioning. Although clinical guidance highlights the importance of identifying whether the child has intolerance to loud sounds and managing this appropriately, there are currently no assessment or treatment methods that have been designed and tested for use with children with hyperacusis. A review is therefore indicated to consider the profile of children with hyperacusis as a basis for future research into their assessment and treatment.

Method

A scoping review methodology was followed with literature searches conducted in Embase, PsychINFO, PubMed CENTRAL, Scopus, Web of Science and Google Scholar. Research articles were included if they reported on research studies describing children diagnosed with hyperacusis, providing clinical profile information, and/or reporting on an assessment or management method for children with a primary complaint of hyperacusis. Data were charted on Excel and verified by a second researcher. Twenty-one research articles were included.

Results

Children with hyperacusis are typically described in terms of age at presentation, troublesome sounds, physical sensation, behavioural reactions, coping strategies, comorbid conditions and impact on daily life. Methods of assessing the children include semi-structured interviews, questionnaires, neurological assessment, observation and uncomfortable loudness levels. Management methods include psychological therapy, sound therapy, tinnitus retraining therapy, medication and neuro-rehabilitation.

Conclusion

The information we catalogued on various elements of clinical profile, assessment and management can serve as a stepping stone in future research developing questionnaires for clinical measurement of the impact of hyperacusis on children, and the measurement of treatment related change in clinic and in trials. Positive outcomes were noted by the authors following all of the above treatments; future research must compare these and specify the parameters for optimal results.

An evaluation of paediatric tinnitus services in UK National Health Service audiology departments

Background

Whilst evidence indicates many children experience troublesome tinnitus, specialist services for children are far less established than those available for adults. To date, there is limited understanding of how paediatric tinnitus is managed in the UK, and to what extent current practice reflects what is recommended. This service evaluation aimed to 1) profile how tinnitus in children is managed in UK clinical practice, and assess to what extent care provided by services reflects advice included in the British Society of Audiology (BSA) Tinnitus in Children Practice Guidance, 2) collate clinician opinions on how services may be optimised, and 3) identify common problems experienced by children who present with bothersome tinnitus in clinic.

Methods

As part of a larger survey, eight questions regarding services for paediatric tinnitus were distributed to UK NHS audiology services via email and social media. Representatives from eighty-seven services responded between July and September 2017.

Results

Fifty-three percent of respondents reported that their department provided a paediatric tinnitus service. Among these services, there was widespread use of most BSA recommended assessments and treatments. Less widely used practices were the assessment of mental health (42%), and the use of psychological treatment approaches; cognitive behavioural therapy (CBT) (28%), mindfulness (28%), and narrative therapy (14%). There was varied use of measurement tools to assess tinnitus in children, and a minority of respondents reported using adult tinnitus questionnaires with children. Frequently reported tinnitus-related problems presented by children were sleep difficulties, concentration difficulties at school, situation-specific concentration difficulties, and emotional distress.

Conclusions

Approaches used to manage children with troublesome tinnitus in UK NHS services are largely consistent and reflective of the current practice guidance. However, findings from this study indicate specialist staff training, access to child-specific tools, and the treatment and referral of children with tinnitus-related psychological problems represent key areas in need of optimisation.

A scoping review to catalogue tinnitus problems in children

BACKGROUND

The reported prevalence of tinnitus in children is similar to that in adults. However, unlike adults, there is relatively little understanding of the tinnitus-related problems children experience. Knowledge of the problems experienced by adults has led to the development of numerous clinical questionnaires used by health professionals in assessment and treatment practices; to date no child-specific questionnaire measure of tinnitus has been developed. To support development of a questionnaire measure of tinnitus in children, the aim of this scoping review was to catalogue the peer-reviewed and grey scientific literature according to 1) the methods used to identify problems experienced by children with tinnitus, 2) tinnitus-related problems observed in or reported by children, and 3) research recommendations suggested by investigators with regards to tinnitus in children.

METHODS

A scoping review was conducted following an established methodological framework. Records were included where a tinnitus-related problem was reported in a child 18 years or younger, and tinnitus was reported as the primary complaint. Tinnitus problems were extracted and categorised into problem themes.

RESULTS

Thirty-five records met the inclusion criteria for this review. Methods used to identify tinnitus-related problems in children, and the number and range of problems reported, varied across the records. Symptom impact was summarised according to six problem themes; Physical health, Cognitive health, Hearing and listening, Emotional health, Quality of life, and Feeling different/isolated. Identified research recommendations highlighted a demand for more standardised approaches.

CONCLUSIONS

The findings evidence the detrimental impact tinnitus can have on a child's quality of life and emotional wellbeing. The current British Society of Audiology Tinnitus in Children Practice Guidance recommends management practices to address the most broadly reported problems identified in this review; sleep difficulties, emotional difficulties, and concentration and hearing problems at school. Given the finding of this review, we suggest problems relating to the impact of tinnitus on quality of life and feelings of isolation are also important problem domains to consider when managing a child who has tinnitus. Current variability in the approach to identifying children's tinnitus problems underlines the importance of developing a standardised and dedicated measure of tinnitus in children.

Sensory neurologic disorders: Tinnitus

Tinnitus is the sensation of hearing a sound with no external auditory stimulus present. It is a public health issue correlated with multiple comorbidities and precipitating factors such as noise exposure, military service, and traumatic brain injury, migraine, insomnia, small vessel disease, smoking history, stress exposure, anxiety, depression, and socioeconomic status. Clinical experience and a recent literature review point at tinnitus as a neuropsychiatric condition involving both auditory and nonauditory cortical areas of the brain and affecting brain-auditory circuitry. In fact, brain-ear connections have been highlighted in different models. Forward management of this disorder should take this body of research into consideration as tinnitus remains a challenging condition to evaluate and treat with current management protocols still symptomatic at best. With a better understanding of the etiologic factors and comorbidities of tinnitus, additional research trials and new therapeutic approaches could see the light to tackle this public health disability bringing hope to patients and doctors.

Hyperacusis in children: The Edinburgh experience

OBJECTIVES

This study aimed to determine the factors associated with hyperacusis in children referred to an audiology-led paediatric hyperacusis clinic in a Paediatric tertiary centre. It also aimed to identify current management strategies in paediatric hyperacusis and their outcomes.

METHODS

Retrospective cohort study conducted by case note and AuditBase^® review over a 5-year period (March 2010 to March 2015) in a tertiary Paediatric ENT and Audiology service.

RESULTS

412 children were referred with hyperacusis during the 5-year period. All children were assessed and managed within a dedicated Paediatric hyperacusis clinic. Median age at referral was 7 years. 76% were boys (n = 313). On average, children were sensitive to 6 identifiable sound stimuli at presentation (range 1-20). 82% complained of sensitivity to noise from household appliances and hand dryers. 60% had a background history of autistic spectrum disorder (ASD), followed by attention deficit hyperactivity disorder (ADHD) and other neurodevelopmental problems. In 91% management comprised behavioural therapy and provision of a 'sound-ball' (Wellcare^® Naturcare Relaxation Therapy Ball) to take home. Of these, 25% did not attend their first review appointment. A further 25% were considered to have sufficient symptom improvement to permit discharge after a single clinic review. Only 2% of children required more than 3 review sessions before achieving resolution of symptoms.

CONCLUSIONS

In our paediatric cohort, hyperacusis is more common in boys and in those children with ASD. A combined treatment approach with behavioural therapy and the provision of a sound-ball has a very high success rate in our experience.

Hyperacusis in children: A clinical profile

OBJECTIVE

Hyperacusis is commonly seen in clinical paediatric practice and can be distressing for the children and their families. This paper looks at the clinical profile of children seen for hyperacusis in a paediatric audiology service and reviews the possible underlying mechanisms.

METHODS

Retrospective study of case notes of 61 children with troublesome hyperacusis seen in the paediatric audiology service, looking at their clinical presentation and presence of other medical conditions.

RESULTS

Hyperacusis was the main presenting complaint in more than half of the cases (n = 31, 51%). The commonest age at presentation with this problem was 3-4 years (n = 33, 54%). Hearing was normal in the majority of these children (n = 41, 67%). An active middle ear problem was observed in nearly half (n = 29, 48%) of all the children, of which glue ear (otitis media with effusion, OME) was the commonest. Presence of a neurodevelopmental condition was found in almost half (n = 28, 46%) of these patients of which autistic spectrum disorder was the commonest (8/61, 13%). In nearly one-fourth of the children (23%), presence of both middle ear problems and neurodevelopmental was noted. Tinnitus was an accompanying symptom reported in 11% of all the patients.

CONCLUSION

Hyperacusis may commonly present at a very young age. Awareness of different clinical presentations, presence of other medical conditions and possible underlying pathomechanisms in children with hyperacusis can be helpful for clinicians in informing prognosis, counselling and in individualising management plan.

Clinical Characteristics of Troublesome Pediatric Tinnitus

Objectives:

The frequency of tinnitus in children and adults is practically the same. However, although adults reveal their symptoms and seek for medical aid, the suffering often remains unrecognized in the young. This is due to both the inability of children to properly describe their symptoms and the lack of recognition.

Materials and methods:

Among 5768 patients entering our department with complaints of tinnitus between 2010 and 2015, there were only 112 children. A full clinical history and medical status had been determined at the time of presentation and were analyzed retrospectively.

Results:

The average duration from first complain to clinical presentation was approximately 12 months. A normal hearing capability of less than 25 dB was measured in 80% of the cases. Only 23 patients presented with a hearing impairment. The causes ranged from hearing loss, previous orthodontic treatment, noise trauma, middle ear aeration, muscular neck tension, and skull base fracture. Typical co-morbidities such as sleeping disorders, concentration disorders, and hyperacusis were observed.

Conclusions:

This retrospective study shows that recognition of tinnitus in the childhood is generally delayed. A better characterization of complaints and triggers, however, is a prerequisite to sensitize medical personnel and caretakers for the suffering and to avoid developmental impairments.
