An Audiometric Study of Two Hundred Cases of Subjective Tinnitus

Heari ng aids may be a option to improve tinnitus and hearing loss. Aim: to evaluate tinnitus after one month use of BTE hearing aids with open molds and pressure vent molds in patients with symmetric sensorineural hearing loss. Methods: 50 patients seen at our Tinnitus Clinic who presented bilateral tinnitus and hearing loss underwent a randomized blind crossover clinical trial: 26 first used BTE hearing aids with open molds, and the remaining 24 first used pressure vent molds. After 30 days using the first mold and a wash-out period, the type of earmold was changed and was applied for another 30-day-period. Tinnitus evaluation was done qualitatively (improved, unchanged and worsened) and quantitatively (variation on a numeric scale from 0 to 10). Results: 82% of the cases reported improvement of tinnitus with at least one type of earmold; there was no significant difference in the reduction of discomfort due to tinnitus in the quantitative and qualitative evaluations. Although similar tinnitus control was obtained with both methods, 66% of the patients preferred the open mold. Conclusion: In a shortterm evaluation improvement of tinnitus by the use of hearing aids does not depend on earmold ventilation.

A eficácia do molde aberto para o controle do zumbido

“…According to different reports, 85 to 96% of the patients with tinnitus present some level of hearing loss [4][5][6][7][8] and only 8 to 10% present normal audiometry 9 . In this last group, the isolated presence of tinnitus suggests that it may be a primary symptom of diseases that are only diagnosed after the onset of hearing loss.…”

Zumbido em pacientes com audiometria normal: caracterização clínica e repercussões

et al. 2005

Pat ients with tinnitus and normal hearing constitute an important group, given that findings do not suffer influence of the hearing loss. However, this group is rarely studied, so we do not know whether its clinical characteristics and interference in daily life are the same of those of the patients with tinnitus and hearing loss. Aim: To compare tinnitus characteristics and interference in daily life among patients with and without hearing loss. Study design: historic cohort. Material and Method: Among 744 tinnitus patients seen at a Tinnitus Clinic, 55 with normal audiometry were retrospectively evaluated. The control group consisted of 198 patients with tinnitus and hearing loss, following the same protocol. We analyzed the patients' data as well as the tinnitus characteristics and interference in daily life. Results: The mean age of the studied group (43.1 ± 13.4 years) was significantly lower than that of the control group (49.9 ± 14.5 years). In both groups, tinnitus was predominant in women, bilateral, single tone and constant, but there were no differences between both groups. The interference in concentration and emotional status (25.5% and 36.4%) was significantly lower in the studied group than that of the control group (46% and 61.6%), but it did not happen in regard to interference over sleep and social life. Conclusions: Patients with tinnitus and normal hearing showed similar characteristics when compared to those with hearing loss. However, the age of the patients and the interference over concentration and emotional status were significantly lower in this group.

“…Estes dados diferem da literatura pesquisada, em que a maioria dos autores referiu que geralmente o pitch do zumbido tende a ser agudo, apresentando-se acima de 3000Hz na maioria dos pacientes 18,24 , de 6000Hz a 8000Hz 26 , variando de 3100Hz a 10300Hz 23,25 e de 5000Hz a 10000Hz 17 para a maioria dos pacientes.…”

O zumbido é uma desordem extremamente freqüente em pacientes com perda auditiva, atingindo cerca de 40 milhões de pessoas nos EUA, afetando aproximadamente 1/3 da população acima dos 65 anos de idade. A prática clínica tem demonstrado que pacientes portadores de perda auditiva associada a zumbido beneficiam-se com o uso de próteses auditivas, pois estas, além de melhorarem a compreensão da conversação, aliviam o zumbido. Objetivo: No presente trabalho, procurou-se verificar a eficiência da adaptação de próteses auditivas na redução ou eliminação do zumbido em pacientes com perda auditiva. Forma de estudo: Estudo de série. Material e Método: Foram avaliados 47 indivíduos adultos, sendo 32 do sexo feminino e 15 do sexo masculino, com idades entre 32 e 88 anos, com indicação médica para adaptação de prótese auditiva. Realizou-se análise e avaliação subjetiva da sensação de zumbido por meio da técnica da acufenometria, caracterizando-o quanto ao pitch e loudness, e acompanhamento dos pacientes durante um ano afim de verificar se houve melhora do zumbido após a adaptação da prótese auditiva. Resultados: A maioria dos pacientes (87,2%) referiu melhora do zumbido com o uso da prótese auditiva, sendo que em 51% destes o zumbido desapareceu completamente. O tempo de uso da prótese necessário para a melhora do zumbido foi de 3 a 8 meses para a maioria dos indivíduos. As características da prótese auditiva, como modelo, tecnologia e ventilação, não influenciaram a melhora do zumbido. Conclusão: A adaptação de próteses auditivas mostrou-se eficaz na redução ou eliminação do zumbido em pacientes portadores de perda auditiva associada a zumbido. Ti nnitus is a disorder extremely frequent in patients with hearing loss. It affects more than 40 milion people in the USA, affecting about 1/3 of the population above 65 years old. Clinical experience has been demonstrating that patients with hearing loss and tinnitus have great benefits with the hearing aid because it helps out the comprehension of conversation while relieves tinnitus. Aim: In this work, we have studied the efficacy of hearing aids on diminishing or eliminating tinnitus in patients with hearing loss. Study design: Series study. Material and Method:We evaluated 47 patients (32 women and 15 men) with ages ranging from 32 to 88 years old and medical indication for fitting a hearing aid. We subjectively investigated the sensation of tinnitus matching frequency (Hz) and loudness (dB) through the technic of acuphenometry and we have attended the patients for one year aiming to verify if there was a relief of tinnitus after the hearing aid fitting. Results:The majority of patients (87,2%) refered relief of tinnitus with the use of the hearing aid. In 51% of these patients tinnitus has completely desapeared. It was necessary to use the hearing aid for some months (3-8) to obtain the relief of tinnitus in the majority of patients. The characteristics of the hearing aids, as model, tecnology and vent, had no influence on the relief of tinnitus. Conclusions:The use of the hear...
