    Smoking is a public health concern and we are still unsure of its relation with auditory problems. AIM: To study the effects of cigarette smoking in auditory thresholds, in otoacoustic emissions and in their inhibition by the efferent olivocochlear medial system. MATERIALS AND METHODS: 144 adults from both genders, between 20 and 31 years of age, smoking and non-smoking individuals were submitted to conventional and high-frequency audiometry, transient stimuli otoacoustic emissions and suppression effect investigation. RESULTS: smokers presented worse auditory thresholds in the frequencies of 12.500Hz in the right ear and 14,000 kHz in both ears. Regarding the otoacoustic emissions, smokers group presented a lower response level in the frequencies of 1,000Hz in both ears and 4,000Hz in the left ear. Among smokers there were more cases of cochlear dysfunction and tinnitus. CONCLUSION: Our results suggest that cigarette smoking has an adverse effect on the auditory system.

    Eficácia da avaliação audiométrica no tratamento medicamentoso da otospongiose
    (Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2012-04-01) Vicente, Andy de Oliveira; Yamashita, Helio Kiitiro [UNIFESP]; Cruz, Oswaldo Laércio Mendonça [UNIFESP]; Suzuki, Flavia Alencar de Barros [UNIFESP]; Penido, Norma de Oliveira [UNIFESP]; Instituto Cema; Universidade Federal de São Paulo (UNIFESP)
    Otospongiosis is a primary osteodystrophy of the otic capsule that affects genetically predisposed individuals and leads to a progressive hearing loss. AIM: To evaluate the applicability of audiometric evaluation during drug treatment for otospongiosis. MATERIALS AND METHODS: A prospective, randomized, controlled, double-blind study involving 26 patients with clinical, audiometric and CT scan image of otosclerosis. Patients eligible for the study were divided into three groups (A, B and C) and received treatment with alendronate sodium (B), sodium fluoride (C) and placebo (A) for 6 months. After this period they were submitted to new tests. RESULTS: There were not statistically significant differences between air and bone conduction (gap). We also found no differences in the speech recognition threshold (SRT) and speech discrimination (IRF) between before and after treatment. CONCLUSION: After six months of drug treatment the audiometric evaluation kept the same hearing thresholds, suggesting stabilization of the otospongiotic lesions.

    A eficiência das emissões otoacústicas transientes e audiometria tonal na detecção de mudanças temporárias nos limiares auditivos após exposição a níveis elevados de pressão sonora

    Exposure to noise has a harmful effect on the auditory health of workers. AIM: The main goal of this paper was to establish the role of pure-tone audiometry and evoked transient otoacoustic emissions in the detection of small temporary auditory changes after exposure to high sound pressure levels. Study Design: a cross-sectional cohort study. MATERIAL AND METHODS: 30 otologically normal subjects aged between 20 and 35 years were submitted to pure-tone audiometry and evoked transiente otoacoustic emissions before and after 5 hours of exposure to high sound pressure levels (betweeen 80 and 90 dB). RESULTS: For pure-tone audiometry the largest changes occurred at high frequencies - from 3 KHz to 8 KHz after exposure. The evoked transient otoacoustic emissions showed reduced reproductibility from 1 KHz to 4 KHz after exposure to noise. CONCLUSION: We noted that both pure-tone audiometry and evoked transient otoacoustic emissions had a role in detecting statistically significant changes in the auditory threshold and in reproductibility, after exposure to high sound pressure levels.

    Monitoramento da audição de pacientes expostos à cisplatina

    Cisplatin is an antineoplasic drug, which has ototoxicity as a side effect. The goals of this paper were to evaluate the audiological behavior in osteosarcoma patients treated with cisplatin and to verify which evaluation method is the best for early detection of drug induced hearing loss. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: 13 patients, that received four cisplatin cycles of 120 mg/m²/cycle divided in two days (60 mg/m²/day), were evaluated prior to start of chemotherapy, prior to each scheduled course and at the end of treatment. It was performed the pure tone audiometry (250 to 18000 Hz) and the transitory and distortion product otoacoustic emission (TOAE and DPOAE). RESULTS: In the mean values, it was observed hearing loss, after 480 mg/m² cumulative cisplatin dosage, beginning at 8 kHz. At the individual values, it was observed that 15,3% had mild to moderate hearing loss beginning at 3kHz, 15,3% beginning at 4 kHz, 15,3% beginning at 6 kHz and 15,3% beginning at 8 kHz. TOAE did not show changes before the audiometry. DPOAE showed smaller amplitude after the cycles of cisplatin, but this change happened together with the audiometry - not prior. CONCLUSION: The high frequency audiometry was more efficient to detect early ototoxicity. TOAE and DPOAE can be used as complement tests. All cisplatin exposed patients showed high frequency hearing loss, 30,6% showed hearing loss in important frequencies (3 and 4 kHz) for speech comprehension.

    Sensibilidade, especificidade e valores preditivos da queixa auditiva comparados com diferentes médias audiométricas

    Hearing loss in the elderly is one of the most incapacitating communication disorders, preventing them to fully perform their tasks in society. AIM: This study aimed to determine what is the best tool that together with the audiometric tests better represents the hearing loss reported by the elderly and which frequencies in the audiometric test must be considered to determine the hearing loss degree. STUDY: Clinical prospective. MATERIALS AND METHODS: 71 elderly with ages between 60 and 82 years old were assessed. The subjects were submitted to a conventional audiometric assessment and a Hearing Handicap Inventory for the Elderly (HHIE) questionnaire. Three audiometric averages were analyzed and compared with the results obtained in the complete form (HHIE) and in its reduced form (HHIE-S). RESULTS: specificity showed values between 43.5% and 58.5% for HHIE with the different audiometric averages and values between 50% and 63.4% for the HHIE-S. CONCLUSION: audiometric average pure tone thresholds in the frequencies of 4kHz and 6kHz found in the audiometric assessment did not contribute to the self-reported hearing handicap perception. The correlation between HHIE-S and PTA1 had the best specificity (63.4%) and best positive predictive value (62.5%).
