The quality of voice in coal-miners after burn/inhalation injury due to methane explosure
Journal Title: Otolaryngologia Polska - Year 2012, Vol 66, Issue 2
Abstract
SUMMARY The job as a coal-miner exposes to the great risk. One of the most dangerous health hazard is a burn/inhalation injury during the methane explosion. The victims undergo physical trauma, effect of high temperature and inhalation of toxic gases and products of incomplete combustion. As a result of inhalation injury both, upper and lower airways are affected. The aim of the study was to analyse the relationship between burn/inhalation injury and quality of voice in affected coal-miners. A group of 23 patients (men) in age from 28 to 59 (mean 38.5) 3 years after burn/inhalation injury participated in this study. The voice evaluation based on ENT examination, videlaryngostroboscopy, acoustic analysis, MPT parameter and GRBAS analysis was performed. The special control group of coal-miners served as a control. On the basis of the subjective evaluation and the objective acoustic analysis, aerodynamic parameter and videlaryngostroboscopy the worse quality of voice in the group of injured coalminers was shown in comparison to the control group. No substantial correlation between the acoustic parameters, MPT parameter and ventilating rates was found.
