Standard and Extend High-Frequency Audiometry in Sudden Sensorineural Hearing Loss: Impacts on Tinnitus and Mental Health.

OBJECTIVE: To analyze the results of auditory assessment in standard (SA) and extended high-frequency (EHF) audiometry, associating the findings with sudden tinnitus and mental health of patients with unilateral sudden sensorineural hearing loss (SSNHL). STUDY DESIGN: Prospective, cohort study. SETTING: Outpatient otology clinic in a tertiary care hospital. SUBJECTS AND METHODS: Patients experiencing unilateral SSNHL were evaluated with pure-tone audiometry performed at frequencies of 250 to16,000 Hz, tinnitus pitch and loudness matching tests, Tinnitus Handicap Inventory (THI), Analog and Visual Scale (AVS) for bothersome tinnitus, and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Eighteen patients with unilateral SSNHL were assessed. After starting treatment, there was a significant improvement in the SA (71.1 dB to 50 dB; p < 0.001*) and EHF audiometry (64.5 dB to 54.4 dB; p < 0.001*) thresholds at 15 days, and this persisted at 30 days of follow-up. Significant improvements were seen for tinnitus in loudness, VAS, and THI and for mental health in the realms of anxiety and depression by HADS. Despite improvements in SA, persistent EHF hearing loss was accompanied by persistent tinnitus, but it was of diminished loudness. CONCLUSION: Despite improvement in pure-tone thresholds by SA, a subset of unilateral SSNHL patients did not experience hearing recovery in EHF thresholds and reported persistent tinnitus. We postulate that their diminished anxiety and better mental health may be related to both hearing improvement in standard audiometry and reduction in tinnitus loudness. This pilot prospective study investigates the utility of performing EHF audiometry to better understand outcomes in patients with SSNHL.

REVISITING TINNITUS AUDIOLOGICAL REHABILITATION

Current research shows tinnitus as more than an auditory phenomenon, but an emotional and cognitive dimension experience. Besides issues involving tinnitus perception and reaction, there is a third dimension: cognition. Both audiological assessment and rehabilitation need to follow these principles and be more comprehensive. The use of sounds to treat tinnitus is described in several papers and has different purposes. It includes hearing aid fitting if hearing loss is detected and the use of sound generator devices. But there are some cases in that hearing loss rehabilitation is not enough and cases of tinnitus and/or sound intolerance suffering without detectable hearing loss in conventional measures. There is no exclusive way for tinnitus patients' auditory rehabilitation. Based on theoretical proposals and literature, we suggest possibilities of intervention to be even more explored and personally adapted for tinnitus patients: cognitive auditory training and the use of mindfulness-based exercises, sound stimulation during sleep, and restoring the pleasure of listening.

Psychoacoustic classification of persistent tinnitus / Classificação psicoacústica do zumbido persistente

Abstract Introduction: Tinnitus is a difficult to treat symptom, with different responses in patients. It is classified in different ways, according to its origin and associated diseases. Objective: to propose a single and measurable classification of persistent tinnitus, through its perception as sounds of nature or of daily life and its comparison with pure tone or noise, of high or low pitch, presented to the patient by audiometer sound. Methods: A total of 110 adult patients, of both genders, treated at the Tinnitus Outpatient Clinic, were enrolled according to the inclusion and exclusion criteria. Otorhinolaryngologic and Audiological, Pitch Matching and Loudness, Visual Analog Scale, Tinnitus Handicap Inventory and Minimum Masking Level assessments were performed. Results: In these 110 patients, 181 tinnitus complaints were identified accordingly to type and ear, with 93 (51%) Pure Tone, and 88 (49%) Noise type; 19 at low and 162 at high frequency; with a mean in the Pure Tone of 5.4.07 in the Visual Analog Scale and 12.31 decibel in the Loudness and a mean in the Noise of 6.66 and 10.51 decibel. For Tinnitus Handicap Inventory and Minimum Masking Level, the 110 patients were separated into three groups with tinnitus, Pure Tone, Noise and multiple. Tinnitus Handicap Inventory higher in the group with multiple tinnitus, of 61.38. Masking noises such as White Noise and Narrow Band were used for the Minimum Masking Level at the frequencies of 500 and 6000 Hz. There was a similarity between the Pure Tone and Multiple groups. In the Noise group, different responses were found when Narrow Band was used at low frequency. Conclusion: Classifying persistent tinnitus as pure tone or noise, present in high or low frequency and establishing its different characteristics allow us to know its peculiarities and the effects of this symptom in patients' lives.

Effectiveness of sound therapy in patients with tinnitus resistant to previous treatments: importance of adjustments / Eficácia da terapia sonora em pacientes com zumbido resistente a tratamentos anteriores: importância dos ajustes

ABSTRACT INTRODUCTION: The difficulty in choosing the appropriate therapy for chronic tinnitus relates to the variable impact on the quality of life of affected patients and, thus, requires individualization of treatment. OBJECTIVE: To evaluate the effectiveness of using sound generators with individual adjustments to relieve tinnitus in patients unresponsive to previous treatments. METHODS: A prospective study of 10 patients with chronic tinnitus who were unresponsive to previous drug treatments, five males and five females, with ages ranging from 41 to 78 years. Bilateral sound generators (Reach 62 or Mind 9 models) were used daily for at least 6 h during 18 months. The patients were evaluated at the beginning, after 1 month and at each 3 months until 18 months through acuphenometry, minimum masking level, the Tinnitus Handicap Inventory, visual analog scale, and the Hospital Anxiety and Depression Scale. The sound generators were adjusted at each visit. RESULTS: There was a reduction of Tinnitus Handicap Inventory in nine patients using a protocol with a customized approach, independent of psychoacoustic characteristics of tinnitus. The best response to treatment occurred in those with whistle-type tinnitus. A correlation among the adjustments and tinnitus loudness and minimum masking level was found. Only one patient, who had indication of depression by Hospital Anxiety and Depression Scale, did not respond to sound therapy. CONCLUSION: There was improvement in quality of life (Tinnitus Handicap Inventory), with good response to sound therapy using customized settings in patients who did not respond to previous treatments for tinnitus.

Resumo Introdução: A dificuldade em escolher a terapia apropriada para zumbido crônico encontra-se nas suas diversas formas de impacto sobre a qualidade de vida dos pacientes e requer a sua individualização. Objetivo: Avaliar a eficácia do uso do gerador de som com ajustes individuais para aliviar o zumbido em pacientes sem resposta aos tratamentos anteriores. Método: Um estudo prospectivo em 10 pacientes, 5 homens e 5 mulheres, na faixa etária de 41 a 78 anos com zumbido crônico e resistente a tratamentos medicamentosos. Foram utilizados geradores de som bilaterais nos modelos Reach 62 ou Mind 9 por no mínimo 6 horas diárias durante 18 meses. Os pacientes foram avaliados no início, depois de 1 mês e a cada 3 meses até 18 meses através da acufenometria, Minimum Masking Level (MML), Tinnitus Handicap Inventory (THI), Escala Visual Analógica (EVA) e Hospital Anxiety and Depression Scale (HADS). Os geradores de som foram ajustados em cada visita. Resultado: Houve uma redução do THI em 9 pacientes usando-se um protocolo com uma abordagem personalizada, independente das características psicoacústicas do zumbido. A melhor resposta ao tratamento ocorreu naqueles pacientes com zumbido do tipo apito. Encontramos uma correlação entre os ajustes e a intensidade do zumbido e o MML. Apenas um paciente com indicação de depressão HADS não respondeu à terapia sonora. Conclusão: Houve uma melhora na qualidade de vida (THI) com boa resposta a terapia sonora com ajustes personalizados em pacientes resistentes a tratamentos anteriores para o zumbido.

Prognostic and Evolutive Factors of Tinnitus Triggered by Sudden Sensorineural Hearing Loss.

INTRODUCTION: The association between sudden sensorineural hearing loss (SSNHL) and tinnitus is frequent. Its correlation with the auditory prognosis remains controversial. The objective of the study is to evaluate tinnitus of which onset is concurrent with SSNHL and analyze it as a prognostic factor and its correlation with hearing recovery. MATERIALS AND METHODS: A prospective cohort study was conducted with 30 patients with SSNHL. Serial audiometry was performed and the Tinnitus Handicap Inventory (THI) was applied at the initial consultation and after treatment. RESULTS: Tinnitus had an incidence of 93.3%, with an initial mean THI of 63.6%. The mean decrease in THI was significant in all scale domains. However, there was no statistically significant difference between the degrees of tinnitus and hearing loss, as well as between hearing recovery percentage in relation to the degree of tinnitus. The correlation of THI gain with the hearing recovery rate was negative (the greater the decrease in the level of tinnitus discomfort, the greater the hearing recovery rate), being significant only in the emotional domain of THI, but showing a poor correlation. DISCUSSION: There was a reduction in the level of tinnitus discomfort, as measured by THI, after treatment of SSNHL. There is a correlation between tinnitus and hearing improvement in patients with SSNHL only in the emotional domain of THI, but this correlation is considered poor. The degree of tinnitus severity as measured by THI was not proportional to the hearing loss and is not a prognostic factor for hearing improvement.

Variables with prognostic value in the onset of idiopathic sudden sensorineural hearing loss / Variáveis com valor prognóstico no momento da instalação da perda auditiva neurossensorial súbita idiopática

ABSTRACT INTRODUCTION: The establishment of an individualized prognostic evaluation in patients with a diagnosis of idiopathic sudden sensorineural hearing loss (ISSHL) remains a difficult and imprecise task, due mostly to the variety of etiologies. Determining which variables have prognostic value in the initial assessment of the patient would be extremely useful in clinical practice. OBJECTIVE: To establish which variables identifiable at the onset of idiopathic sudden sensorineural hearing loss have prognostic value in the final hearing recovery. METHODS: Prospective, longitudinal cohort study. Patients with ISSHL followed by the Department of Otology-Neurotology of a quaternary hospital were included. The following variables were evaluated and correlated with final hearing recovery: age, gender, vertigo, tinnitus, initial degree of hearing loss, contralateral ear hearing, and elapsed time to treatment. RESULTS: 127 patients with ISSHL were evaluated. Rates of absolute and relative recovery were 23.6 dB and 37.2% respectively. Complete hearing improvement was observed in 15.7% patients; 27.6% demonstrated significant improvement and improvement was noted in 57.5%. CONCLUSION: During the onset of ISSHL, the following variables were correlated with a worse prognosis: dizziness, profound hearing loss, impaired hearing in the contralateral ear, and delay to start treatment. Tinnitus at the onset of ISSHL correlated with a better prognosis.

RESUMO Introdução: Elaborar avaliação prognóstica individualizada em pacientes com diagnóstico deperda auditiva neurossensorial súbita idiopática (PANSI) permanece tarefa árdua e imprecisa devido, em grande parte, à variedade de etiologias. A determinação de quais variáveis teriam valor prognóstico na avaliação inicial do paciente seria de extrema utilidade na prática clínica. Objetivo: Estabelecer quais variáveis, identificáveis no momento de instalação da perda auditiva neurossensorial súbita idiopática, têm valor prognóstico na recuperação auditiva final. Método: Estudo de coorte prospectivo, longitudinal. Incluídos pacientes com PANSI acompanhados pela Disciplina de Otologia-Neurotologia de um hospital quaternário. As seguintes variáveis foram avaliadas e correlacionadas com a recuperação auditiva final: idade, gênero, vertigem, zumbido, grau de perda auditiva inicial, audição na orelha contralateral, tempo para início de tratamento. Resultado: Foram avaliados 127 pacientes com PANSI. As taxas de recuperação absoluta e relativa foram 23,6 dB e 37,2% respectivamente. Apresentaram melhora completa da audição 15,7% dos pacientes; 27,6% apresentaram melhora significativa e 57,5% melhora. Conclusão: No momento da instalação da PANSI, as seguintes variáveis correlacionaram-se com pior prognóstico: vertigem, perda auditiva profunda, audição alterada na orelha contralateral e demora para início do tratamento. Presença de zumbido na instalação da PANSI correlacionou-se com melhor prognóstico.
