Abstract
Organic solvents have been reported to adversely affect human health, including hearing health. Animal models have demonstrated that solvents may induce auditory damage, especially to the outer hair cells. Research on workers exposed to solvents has suggested that these chemicals may also induce auditory damage through effects on the central auditory pathways. Studies conducted with both animals and humans demonstrate that the hearing frequencies affected by solvent exposure are different to those affected by noise, and that solvents may interact synergistically with noise. The present article aims to review the contemporary literature of solvent-induced hearing loss, and consider the implications of solvent-induced auditory damage for clinical audiologists. Possible audiological tests that may be used when auditory damage due to solvent exposure is suspected are discussed. Sumario Se ha reportado que los solventes orgánicos afectan adversamente la salud humana, incluyen la salud auditiva. Los modelos animales han demostrado que los solventes pueden inducir daño auditivo, especialmente en las células ciliadas externas. La investigación en trabajadores expuestos a solventes sugiere que estos productos químicos pueden también inducir daño auditivo afectando las vías auditivas centrales. Los estudios conducidos en animales y en humanos demuestran que las frecuencias auditivas afectadas por la exposición a solventes son diferentes de las afectadas por el ruido, y que los solventes pueden actuar en sinergia con el ruido. El presente artículo pretende revisar la literatura contemporánea sobre hipoacusia inducida por solventes, y hacer consideraciones clínicas para el audiólogo sobre el daño auditivo inducido por solventes. Se discuten posibles pruebas auditivas que pueden ser utilizadas cuando se sospecha daño auditivo debido a la exposición a solventes.Keywords
