Tinnitus update: what can be done for the ringing?

Physicians will frequently encounter patients who report tinnitus. Tinnitus is a symptom whereby there is the perception of sound or sounds in the ear or head in the absence of an external source of sound. Most individuals experiencing tinnitus will have a neutral reaction to the percept, but in a small proportion of patients, tinnitus can be a debilitating symptom. When it causes burden, patients can be affected in multiple different facets of life, including impairment in sleep, hearing cognition and psychological and psychiatric well-being, often resulting in high healthcare utilisation and societal costs. Hence, chronic, disabling tinnitus is a complex condition with multifactorial causes and multiple perpetuating biopsychosocial factors. Despite efforts to increase knowledge about its pathophysiology and research into treatments, little impact on real-world clinical practice has been seen. There are no proven effective pharmacological treatments or complementary medicines specifically for chronic, disabling tinnitus. Despite this, there is a role for treating this condition through a multidisciplinary approach specifically targeting comorbid active psychiatric conditions, using hearing aids in appropriate clinical settings such as in those with a coassociated confirmed hearing loss, and specialised cognitive behavioural therapy for patients reporting bothersome tinnitus. Cognitive behavioural therapy remains the most valuable evidence-based intervention in this regard. This narrative review attempts to summarise the current understanding in terms of pathophysiology, assessment and treatment of tinnitus for the internal physician who may encounter patients with disabling, chronic tinnitus.

Influence of depressive disorders, stress, and personality traits on quality of life after cochlear implantation.

PURPOSE: This study aimed to determine whether preoperative depressiveness, stress, and personality influence quality of life (QOL) after cochlear implant (CI) surgery. METHODS: In this prospective study, 79 patients undergoing CI surgery were evaluated preoperatively and 12 months postoperatively. Disease-specific QOL was assessed with the Nijmegen Cochlear Implant Questionnaire (NCIQ) and general QOL with the WHOQOL-BREF. Depressiveness and stress were assessed with the Patient Health Questionnaire (PHQ-D). The Charlson Comorbidity Index (CCI) was used to classify comorbidities. The Big Five Personality Test (B5T) was used to assess the basic personality dimensions. Speech comprehension was evaluated in quiet with the Freiburg monosyllable test and in noise with the Oldenburg sentence test. RESULTS: After CI surgery, the total NCIQ score improved significantly (Δ 17.1 ± 14.7, p < 0.001). General QOL (WHOQOL-BREF, Δ 0.4 ± 9.9, p = 0.357), stress (Δ 0.25 ± 3.21, p = 0.486), and depressiveness (Δ 0.52 ± 3.21, p = 0.121) were unaffected by CI surgery. Patients without elevated depressiveness (p < 0.01) or stress (p < 0.001) had significantly better total NCIQ scores. The results of the multiple regression analyses show that, after adjusting for the CCI, personality, age, and mental health stress (ß = - 0.495, p < 0.001) was significantly associated with postoperative NCIQ outcome scores. Depressiveness and neuroticism had the strongest influence on the generic QOL (ß = - 0.286 and ß = - 0.277, p < 0.05). CONCLUSION: Stress symptoms and personality traits are significant predictive factors for disease-specific QOL, as well as hearing status. This should be considered in the preoperative consultation and in optimizing the rehabilitation process.

[Rational timepoint of medical rehabilitation in chronic tinnitus : Applying for rehabilitation options for a chronic course]. / Sinnvoller Zeitpunkt medizinischer Rehabilitation bei Tinnitus : Beantragung von Rehabilitationsmöglichkeiten bei chronischem Verlauf.

Chronic tinnitus is a common symptom of the auditory system. A causal therapy does not yet exist. The recommended treatment includes expert counseling, psychotherapeutic interventions, particularly cognitive behavioral therapy, and measures to improve hearing. The treatment modules are multimodal and can be combined individually. Depending on the severity of the different disease dimensions (tinnitus and comorbidities), a rehabilitative approach may be useful for maintaining health and occupational ability. In addition to a thorough and well-founded diagnosis and counseling, specific cognitive behavioral therapy and non-specific psychotherapeutic interventions (mindfulness/relaxation) on an individual or group basis, physiotherapy, and exercise, as well as auditory rehabilitation measures (hearing aids, auditory therapy) in the context of multimodal therapy approaches are necessary.

Speech perception in modulated noise assessed in bimodal CI users.

BACKGROUND: Although good speech perception in quiet is achievable with cochlear implants (CIs), speech perception in noise is severely impaired compared to normal hearing (NH). In the case of a bimodal CI fitting with a hearing aid (HA) in the opposite ear, the amount of residual acoustic hearing influences speech perception in noise. OBJECTIVE: The aim of this work was to investigate speech perception in noise in a group of bimodal CI users and compare the results to age-matched HA users and people without subjective hearing loss, as well as with a young NH group. MATERIALS AND METHODS: Study participants comprised 19 bimodal CI users, 39 HA users, and 40 subjectively NH subjects in the age group 60-90 years and 14 young NH subjects. Speech reception thresholds (SRTs) in noise were adaptively measured using the Oldenburg Sentence Test for the two spatial test conditions S0N0 (speech and noise from the front) and multisource-noise field (MSNF; speech from the front, four spatially distributed noise sources) in continuous noise of the Oldenburg Sentence Test (Ol-noise) and amplitude-modulated Fastl noise (Fastl-noise). RESULTS: With increasing hearing loss, the median SRT worsened significantly in all conditions. In test condition S0N0, the SRT of the CI group was 5.6 dB worse in Ol-noise than in the young NH group (mean age 26.4 years) and 22.5 dB worse in Fastl-noise; in MSNF, the differences were 6.6 dB (Ol-noise) and 17.3 dB (Fastl-noise), respectively. In the young NH group, median SRT in condition S0N0 improved by 11 dB due to gap listening; in the older NH group, SRTs improved by only 3.1 dB. In the HA and bimodal CI groups there was no gap listening effect and SRTs in Fastl-noise were even worse than in Ol-noise. CONCLUSION: With increasing hearing loss, speech perception in modulated noise is even more impaired than in continuous noise.

Interventions against hearing loss as an integral component of successful tinnitus therapy.

Tinnitus very often develops from acute or chronic hearing loss, mainly inner ear deafness. The frequency of the tinnitus mostly corresponds to the frequency range of the hearing loss and is enhanced by down-regulation of inhibition in the central auditory pathway for these frequencies, in addition to focused attention and enhanced arousal for the disturbing sound. Therefore, interventions to improve hearing such as mid-ear surgery or-more often-electronic devices including hearing aids or cochlear implants (CI) are important for the treatment of tinnitus. In this review, the current German S3 guideline "Chronic tinnitus" and recent literature are discussed.

Routine ear health and hearing checks for Aboriginal and Torres Strait Islander children aged under 6 years attending primary care: a national consensus statement.

This consensus statement provides new recommendations for primary care assessment of ear health and hearing status of young Aboriginal and Torres Strait Islander children who are not known to have, or are not being actively managed for, ear health and hearing problems. Any child identified with otitis media should be actively managed. This national consensus statement extends existing treatment and management guidelines. MAIN RECOMMENDATIONS: Undertake checks at least 6-monthly, commencing at 6 months until 4 years of age, then at 5 years. Undertake checks more frequently in high risk settings for children under 2 years, when acceptable to families, or in response to parent/carer concerns. Ask parents/carers about concerns, signs, and symptoms; check children's listening and communication skills; and assess middle ear appearance and mobility. Otoacoustic emissions testing is suggested when equipment is available, primary health practitioners have capability and confidence to use the equipment, and there is local preference for its use. Video otoscopy is suggested for health promotion purposes, and/or for sharing images with other health practitioners. Audiometry should be done as per existing guidelines: when there are parent/carer concerns, signs of persistent/recurrent otitis media, or when listening and communication development is not yet on track. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: Key practice changes include routine use of tympanometry, and listening and communication skills checklists. Implementation will require access to equipment and training; clear information on immediate, practical actions for families; timely pathways to referral services; and a change management process that shifts perception and tolerance of otitis media and its impacts and raises expectations that Aboriginal and Torres Strait Islander children can have healthy ears and hearing.

Knowledge and experience of paramedics concerning patients with hearing and visual disability.

BACKGROUND: A 2017 nationwide disability survey conducted by the General Authority of Statistics in Saudi Arabia, a sample representing the whole population living in Saudi Arabia, reported that approximately 5% and 2% of the Saudi population suffers from visual or hearing impairments, respectively. Patients with these disabilities find it difficult to convey their medical history and chief complaints to paramedics, causing communication breakdowns that can lead to misinterpretation of patient history, leave medical problems unaddressed, and reduce patient engagement and autonomy. We aimed to assess paramedics' knowledge, attitude, and level of confidence when managing patients with visual or hearing problems. METHODS: Descriptive cross-sectional design was used to report the knowledge and experience of paramedics towards patients with hearing/vision disabilities in Saudi Arabia. A validated questionnaire was distributed to our study sample of paramedics in Riyadh, Saudi Arabia between 01, July 2020 and 31, December 2020. Ethical approval was obtained from King Abdullah International Medical Research Center. RESULTS: Ninety-seven participants completed the survey. Male paramedics accounted for 77% of the study participants; 24% were Saudi Red Crescent employees, and 57% were 20-25 years old. Most participants encountered 1-5 cases of patients with hearing disability (55%) as well as patients with visual disability (48%) during their career. Taking medical history was a challenge indicated by 42% of the participants, and 30% reported difficulties in explaining procedures. Of the participants, 44% were confident in handling patients with hearing or visual impairment. There was a strong association between participants who indicated higher confidence levels and those who had obtained specific training for patients with hearing or visual impairments. CONCLUSION: Assisting patients with hearing or visual impairments is challenging, especially during an emergency. We recommend programs that provide specific training in handling hearing or visually impaired patients to close the communication gap in emergent medical situations handled by paramedics or other emergency medicine doctors and nurses.

[Stress and suffering from tinnitus-a psychosomatic approach]. / Stress und Leiden am Tinnitus aus psychosomatischer Sicht.

The development and processing of tinnitus is often associated with stress. There are many publications on this subject that have investigated possible connections between stress perception and tinnitus symptoms using different concepts and different test inventories. In this review, we present the development of Selye's concept of stress using the transactional stress model of Lazarus and its transfer to patients suffering from tinnitus. The literature evaluating the influence of stress on tinnitus symptoms with partly very different concepts is critically reviewed. For example, it is suggested that psychosocial stress has the same likelihood of contributing to tinnitus as noise in the workplace. However, what is striking in previous studies is that "stress" as an influencing variable could not be clearly verified with suitable psychometric test procedures or that no significant differences-to very different comparison groups-could be shown. Finally, a possible therapeutic approach to stress management is outlined.

[Chronic tinnitus: An interplay between somatic and psychological factors]. / Chronischer Tinnitus im Wechselspiel somatischer und psychischer Faktoren.

Chronic tinnitus is a common, sometimes highly distressing phenomenon that can be triggered and maintained by an interplay of physical and psychological factors. Partnering with clinical psychology and psychosomatic medicine, modern otolaryngology integrates both medical (e.g., hearing loss) and psychological influences (e.g., interactions between biographical experiences, personality traits, subjective evaluation of intrapsychic and interpersonal stimuli, emotional states, and intrapsychic or interpersonal emotion regulation strategies). Both groups of variables can influence the intensity and course of chronic tinnitus symptomatology both directly and indirectly, whereby the quality and relative degrees of psychological and physical components in a person's self-experience can fluctuate. With this in mind, the present article distinguishes between chronic tinnitus symptomatology with or without hearing loss-and strongly advocates for an integrated understanding of the symptomatology within a holistic psychological frame of reference. After a brief introduction to the principles of psychosomatic medicine and psychotherapy, the article discusses psychological case conceptualization using a vulnerability-stress-coping (VSC) model as an example, outlines clinical aspects and diagnostics of chronic tinnitus symptomatology, and concludes with a conceptualization of chronic tinnitus-related distress as a function of person-centered VSC interactions.

[Hereditary hearing loss]. / Hereditäre Schwerhörigkeit.

Understanding the genetic basis of hearing loss is becoming increasingly relevant, as 50-70% of congenital hearing loss is hereditary and postlingual hearing loss is also often of hereditary origin. To date, more than 220 genes for hearing loss have been identified and more than 600 syndromes with hearing loss described. This review article explains the classification of genetic hearing loss into syndromic versus non-syndromic forms and the modes of inheritance involved. Some of the most common syndromes (Usher, Pendred, Jervell-Lange-Nielsen, Waardenburg, branchiootorenal, and Alport syndrome) are introductorily described. New sequencing technologies have significantly expanded the diagnostic options for genetic hearing loss and made them more accessible. This text aims to encourage initiation of genetic diagnosis in hearing-impaired patients with suspected hereditary genesis in order to provide the best possible counseling for affected individuals and their families.

[Speech perception in modulated noise assessed in bimodal CI users-German version]. / Sprachverstehen im modulierten Störgeräusch bei bimodal versorgten CI-Tragenden.

BACKGROUND: Although good speech perception in quiet is achievable with cochlear implants (CIs), speech perception in noise is severely impaired compared to normal hearing (NH). In the case of a bimodal CI fitting with a hearing aid (HA) in the opposite ear, the amount of residual acoustic hearing influences speech perception in noise. OBJECTIVE: The aim of this work was to investigate speech perception in noise in a group of bimodal CI users and compare the results to age-matched HA users and people without subjective hearing loss, as well as with a young NH group. MATERIALS AND METHODS: Study participants comprised 19 bimodal CI users, 39 HA users, and 40 subjectively NH subjects in the age group 60-90 years and 14 young NH subjects. Speech reception thresholds (SRTs) in noise were adaptively measured using the Oldenburg Sentence Test for the two spatial test conditions S0N0 (speech and noise from the front) and multisource-noise field (MSNF; speech from the front, four spatially distributed noise sources) in continuous noise of the Oldenburg Sentence Test (Ol-noise) and amplitude-modulated Fastl noise (Fastl-noise). RESULTS: With increasing hearing loss, the median SRT worsened significantly in all conditions. In test condition S0N0, the SRT of the CI group was 5.6 dB worse in Ol-noise than in the young NH group (mean age 26.4 years) and 22.5 dB worse in Fastl-noise; in MSNF, the differences were 6.6 dB (Ol-noise) and 17.3 dB (Fastl-noise), respectively. In the young NH group, median SRT in condition S0N0 improved by 11 dB due to gap listening; in the older NH group, SRTs improved by only 3.1 dB. In the HA and bimodal CI groups there was no gap listening effect and SRTs in Fastl-noise were even worse than in Ol-noise. CONCLUSION: With increasing hearing loss, speech perception in modulated noise is even more impaired than in continuous noise.

[Prospective comparative analysis of cochlear implant patients with single-sided deafness and asymmetric hearing loss with regard to health-related quality of life, tinnitus distress and psychological comorbidities]. / Prospektive Vergleichsanalyse von CI-Patienten mit einseitiger Taubheit und asymmetrischem Hörverlust hinsichtlich der gesundheitsbezogenen Lebensqualität, Tinnitusbelastung und psychischen Komorbiditäten.

BACKGROUND: Patients with single-sided deafness (SSD) and asymmetric hearing loss (AHL) are increasingly being treated with cochlear implants (CI) due to the demonstrated improvements in auditory abilities and quality of life. To date, there are few published studies in which these two groups are comparatively studied. The aim of the current study was to examine which factors differ between those two patient groups, especially preoperatively. METHODS: A secondary analysis of the previously published raw data of 66 prospectively recruited CI patients (21 SSD/45 AHL) was performed. In addition to the hearing outcome, tinnitus distress (tinnitus questionnaire), health-related quality of life (Nijmegen Cochlear Implant Questionnaire, NCIQ), stress (Perceived Stress Questionnaire, PSQ), and psychological comorbidities (General Depression Scale, ADS­L and Generalized Anxiety Disorder scale, GAD-7) were assessed in SSD and AHL patients pre- and postoperatively. RESULTS: Preoperatively, SSD patients showed significantly higher scores in the NCIQ subdomains "elementary" and "advanced sound perception" than the AHL group. Stress (PSQ) and anxiety symptoms (GAD-7) were significantly higher preoperatively in SSD patients than in AHL patients. After CI, these differences were strongly reduced, with minimal differences being detectable between the groups in the investigated domains postoperatively. CONCLUSION: SSD and AHL patients differ significantly preoperatively in terms of their subjective hearing assessment and psychosocial parameters. In SSD patients, psychological stress factors may have a stronger impact on the quality of life than in AHL patients. These aspects should be taken into account in the preoperative counseling and postoperative rehabilitation.

Sympathetic Nervous System Regulation of Auditory Function.

BACKGROUND: The auditory system processes how we hear and understand sounds within the environment. It comprises both peripheral and central structures. Sympathetic nervous system projections are present throughout the auditory system. The function of sympathetic fibers in the cochlea has not been studied extensively due to the limited number of direct projections in the auditory system. Nevertheless, research on adrenergic and noradrenergic regulation of the cochlea and central auditory system is growing. With the rapid development of neuroscience, auditory central regulation is an extant topic of focus in research on hearing. SUMMARY: As such, understanding sympathetic nervous system regulation of auditory function is a growing topic of interest. Herein, we review the distribution and putative physiological and pathological roles of sympathetic nervous system projections in hearing. KEY MESSAGES: In the peripheral auditory system, the sympathetic nervous system regulates cochlear blood flow, modulates cochlear efferent fibers, affects hair cells, and influences the habenula region. In central auditory pathways, norepinephrine is essential for plasticity in the auditory cortex and affects auditory cortex activity. In pathological states, the sympathetic nervous system is associated with many hearing disorders. The mechanisms and pathways of sympathetic nervous system modulation of auditory function is still valuable for us to research and discuss.

Leisure-time physical activity and incidence of objectively assessed hearing loss: The Niigata Wellness Study.

Previous cohort study reported that high physical activity was associated with a low risk of self-reported hearing loss in women. However, no studies have examined the association between physical activity and the development of hearing loss as measured using an objective assessment of hearing loss in men and women. Here, we used cohort data to examine the association between leisure-time physical activity and incidence of objectively assessed hearing loss in men and women. Participants included 27 537 Japanese adults aged 20-80 years without hearing loss, who completed a self-administered physical activity questionnaire between April 2001 and March 2002. The participants were followed up for the development of hearing loss as measured by audiometry between April 2002 and March 2008. During follow-up, 3691 participants developed hearing loss. Compared with the none physical activity group, multivariable adjusted hazard ratios (HRs) for developing hearing loss were 0.93 (95% confidence interval (CI), 0.86-1.01) and 0.87 (0.81-0.95) for the medium (<525 MET-min/week) and high (≥525 MET-min/week) physical activity groups, respectively (p for trend = 0.001). The magnitude of risk reduction was slightly greater in vigorous-intensity activity than in moderate-intensity activity (p for interaction = 0.01). Analysis by sound frequency showed that the amount of physical activity was inversely associated with high frequency hearing loss development (p for trend <0.001), but not with low frequency hearing loss development (p for trend = 0.19). Higher level of leisure-time physical activity was associated with lower incidence of hearing loss, particularly for vigorous-intensity activities and high sound frequencies.

Relation between auditory difficulties and bortezomib-induced peripheral neuropathy in multiple myeloma: a single-center cross-sectional study.

PURPOSE: Bortezomib is a neurotoxic drug used in multiple myeloma and responsible for chemotherapy-induced peripheral neuropathy (CIPN). In a previous cross-sectional study, CIPN prevalence was about 26.9% in 67 patients. A second data analysis was performed to explore the relation between CIPN and auditory difficulties. METHODS: Based on 66 multiple myeloma patients from a single center, auditory difficulties were assessed with a self-questionnaire and compared to sensory CIPN (QLQ-CIPN20 questionnaire), patients' characteristics and anticancer treatments. RESULTS: The prevalence of auditory difficulties was about 42.4% (95% CI [30.6-55.2]) of the 66 patients analyzed and was higher in patients with CIPN than without (82.4% vs. 28.6%, p < 0.001). Auditory difficulties were not related to the characteristics of patients and treatments. The severity of auditory difficulties were correlated to CIPN severity (spearman's coefficient: 0.49, p = 0.009). Odds-ratio of auditory difficulties (multivariable analysis adjusted for sensory CIPN, recreation or professional noise exposure, gender, age, and treatments) was significantly associated with CIPN (18.7, 95% CI [3.0-117.1], p = 0.002). CONCLUSION: This relation between CIPN and auditory difficulties raises concerns about hearing safety in multiple myeloma patients treated by bortezomib. TRIAL REGISTRATION NUMBER: NCT03344328.

Migraine associated with tinnitus and hearing loss in adults: a systematic review.

OBJECTIVE: To describe evidence of migraine-associated tinnitus and hearing loss. DESIGN: This study was registered in PROSPERO and followed the PRISMA guidelines. The inclusion criteria were observational studies with subjects aged ≥18 years, in which the association between migraine and tinnitus and/or hearing loss was evaluated. Reviews, case reports, commentaries, letters to the editor, and studies that included individuals with some diseases were excluded. STUDY SAMPLE: The search yielded 698 articles from electronic databases. Six studies were eligible for this review with 26,166 participants. RESULTS: Most studies have shown an association between migraine and tinnitus, and between migraine and hearing loss. Studies have concluded that migraine presented high odds ratio, and hazard ratio for tinnitus. Another study found a strong association between these conditions (p < 0.001), and two investigations detected the presence of migraine in 10.1 and 22.5% of tinnitus patients. Migraine presented high odds ratio and hazard ratio for hearing loss. Additionally, the studies included were of good quality, adhering to most of the requirements on the JBI Critical Appraisal Checklist. However, a limitation of this review is the small number of studies included. CONCLUSIONS: Associations between migraine, tinnitus, and hearing loss were observed in the included studies.

[(Air-conduction) Hearing aids-indication, designs and applications : Signal processing and importance of individual fitting]. / (Luftleitungs­)Hörsysteme ­ Indikation, Bauformen und Einsatzmöglichkeiten : Signalverarbeitung und die Bedeutung der individuellen Anpassung.

Many people in Germany and worldwide suffer from a reduced communication ability due to impaired hearing. Especially older people are affected. Hearing aids, which pick up ambient sounds, process them, and output airborne sound in the ear canal, can help in most cases. These so-called air-conduction hearing aids are commonly used to compensate for hearing loss and are described in more detail in this article. To this end, indications, differences to other hearing aids and implants, various designs, the importance of individual ear coupling, features of the signal processing, and the importance of the individual hearing aid fitting are explained in detail.

Frequency and Severity of Ear-Nose-Throat (ENT) Symptoms during COVID-19 Infection.

Background and Objectives: Coronavirus disease 2019 (COVID-19) is a new disease entity caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main symptoms of infection at the onset of the pandemic include dyspnea, cough and high fever. Ear−nose−throat (ENT) symptoms are among the ones presented by patients in the course of infection. The aim of the study was to analyze the frequency of ENT symptoms and to assess their severity and duration in COVID-19 patients. Materials and Methods: The study included 337 patients who had been infected with SARS-CoV-2, as confirmed by a PCR test. The study participants were >18 years old; the mean age was 43.98 years ± 13.47 SD. The convalescents completed a questionnaire that contained 26 questions, including 9 detailed questions related to ENT symptoms, such as sore throat, vertigo, dizziness, hearing disorders, olfactory disorders, taste disturbance, headache, cough and dyspnea. The severity of symptoms was assessed using a Visual Analogue Scale (VAS). Results: The most reported ENT symptoms were olfactory disorders, which occurred in 72% of patients. The second most frequent symptom was taste disturbance (68%), VAS = 6.79 ± 3.01. Vertigo and dizziness were reported by 34% of respondents (VAS = 4.01 ± 2.01). Tinnitus was observed in 15% of patients, VAS = 3.87 ± 1.98; 14% of the subjects reported hearing impairment (VAS = 3.81 ± 2.37). Conclusions: Symptoms related to the sense of smell, taste and hearing are some of the most common symptoms in the course of COVID-19, which is important in the therapeutic and epidemiological management of patients. Delayed diagnosis and treatment of symptoms, especially those related to the hearing organ, may result in greater permanent damage.

Otitis media guidelines for Australian Aboriginal and Torres Strait Islander children: summary of recommendations.

INTRODUCTION: The 2001 Recommendations for clinical care guidelines on the management of otitis media in Aboriginal and Torres Islander populations were revised in 2010. This 2020 update by the Centre of Research Excellence in Ear and Hearing Health of Aboriginal and Torres Strait Islander Children used for the first time the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. MAIN RECOMMENDATIONS: We performed systematic reviews of evidence across prevention, diagnosis, prognosis and management. We report ten algorithms to guide diagnosis and clinical management of all forms of otitis media. The guidelines include 14 prevention and 37 treatment strategies addressing 191 questions. CHANGES IN MANAGEMENT AS A RESULT OF THE GUIDELINES: A GRADE approach is used. Targeted recommendations for both high and low risk children. New tympanostomy tube otorrhoea section. New Priority 5 for health services: annual and catch-up ear health checks for at-risk children. Antibiotics are strongly recommended for persistent otitis media with effusion in high risk children. Azithromycin is strongly recommended for acute otitis media where adherence is difficult or there is no access to refrigeration. Concurrent audiology and surgical referrals are recommended where delays are likely. Surgical referral is recommended for chronic suppurative otitis media at the time of diagnosis. The use of autoinflation devices is recommended for some children with persistent otitis media with effusion. Definitions for mild (21-30 dB) and moderate (> 30 dB) hearing impairment have been updated. New "OMapp" enables free fast access to the guidelines, plus images, animations, and multiple Aboriginal and Torres Strait Islander language audio translations to aid communication with families.
