PURPOSE: Thermal trauma has influence on morphology and function on upper and lower airways. The aim of this report is to determine the consequences of thermal trauma on spirometric inspiratory and expiratory parameters and maximal phonation time as well as acoustic analysis.
METHODS: Examined groups were divided into two groups:the group A consisted of 23 miners aged 28–59 yrs who suffered thermal injures due to methane explosion in 2003. The group B served as controls:23 helthly miners aged 25–54 yrs who had worked in silesian coal mines. All subjects had spirometry, and voice analysis using acustic indicator Jitter, Schimer, Fundamental Frequency(Fo) and aerodynamic parameter Maximal Phonation Time(MPT).
RESULTS: The values of expiratory parameters in examined group A in relation to controls differed principially (FEV1 3.0 l vs 4.1,PEF 7.1.vs 9.3 l/sec, MEF50 4.1 vs 5.4 l/sec) Ispiratory parameters differs statistically (FIV1 3.1 vs 4.2 l.,PIF 5.3 vs 7.1 l/sec, MIF50 4.9 vs 6.7 l/sec). In acustic parameters we found statistically differences in Jitt(1.59 vs 0.75),Schim 7.22vs 4.88. No statisyical differences was found in Fundamental Frequency Parameters.Maximal Fonation Time was sigificantly lower in examined group. We found a negative correlation (r=-0.43) of Fo and MEF 50 and FEV1 in burns patients.
CONCLUSION: We concluded that thermal injury had impact for inspiratory and expiratory parameters. Acoustic examination and aerodynamic parameters showed worse voice quality in burn patiets after 3 yrs of accidentThe influence of thermal trauma on quality of voice seems to be poor.
CLINICAL IMPLICATIONS: Based on our results both:lung funtion tests and voice analysis tests are recommended in burn patient.
