Ototoxicidade em indivíduos com uso disfuncional de alcoólicos e com histórico negativo de presbiacusia e exposição a ruído ocupacional

Abstract

OBJECTIVES: To estimate the presence of hearing loss for ototoxicity by typical dysfunctional use of alcohol - including the frequent use of high doses for a long time - controlled by occupational noise exposure and age, to compare the study groups with variables related to sociodemographic data, use of alcohol, tobacco and other psychoactive substances and hearing health. METHODS: Cross-sectional study, men aged between 30 to 50 years, with a negative history of exposure to occupational noise; normal ENT examination, included in two groups: patients with previous use of alcoholics and dysfunctional individuals who had never used dysfunctional alcoholics. Submitted the questionnaire for data collection, otolaryngologic and audiometric. RESULTS: significant differences between the two groups for the variables: education level (p=0,007), pay (p=0,039) and presence of hearing loss typical for ototoxicity (p=0,002). 87,5% of hearing losses in the group of alcoholics were typical loss for ototoxicity, while this rate was only 25,0% among individuals who had never used dysfunctional alcoholics. The variables that showed significant difference in the presence of typical hearing loss for ototoxicity were use-in-life drugs (p=0,017), use-on-life tobacco (p=0,000), reported hearing difficulty (p=0,00), tinnitus (p=0,004) and attendance at religious services (p=0,034). In the process of logistic regression, the final regression model indicated that prior use of dysfunctional alcohol increased the risk by 990% and use-of-life in tobacco increased the risk by 702%. CONCLUSIONS: The results support the evidence that the use of dysfunctional alcoholics are able to unleash the typical hearing loss ototoxicity.
