ABSTRACT
Introduction: hypoacusia by chronic acoustic trauma (HTAC) is one of the main work diseases.
Objective: to analyze the distribution and frequency of hearing loss produced by chronic acoustic trauma (HLON) in workers who attend to Mexican Social Security Institute (IMSS). Also analyze the estimated cost of permanent work disabilities.
Material and methods: we analyze all hearing loss cases of the workers who attend to IMSS in the period between 1992 to 2001, registered in the Subsystem of registration of work’s risk in the IMSS. Measures of central tendency, odds ratio (OR) and direct costs by means were calculated.
Results: the HLON represents 41 % (1867) of all work´s disease , during the period it was observed an increase of number of cases, the average of permanent disabilities, the rate of incidence and the average of rating percentage. The cases solved through a demand showed an increase to 105 % in four years. The estimate monthly cost for every worker was 277 pesos.
Conclusions: the HLON represents an important problem for the IMSS causing social and economic impact. If they don’t take some actions to improve the quality of chronic acoustic trauma diagnosis it will have more serious consequences.
