Paper Abstract

The paper deals with the analysis of the voice function in patients with laryngeal pathology who had undergone Nd:YAG contact laser surgery. Surgery technique is believed to be gentle and sparing not only structurally but also functionally. It was shown that the methods of function evaluation of phonation such as the voice dynamic range, the main tone testing, transient characteristics of speech tracing, spectrography and electroreolaryngography can serve as a helpful tool in diagnostics and treatment follow-up. Benign laryngeal growths, cysts, scarring, hypertrophic laryngitis and cancer tumors comprise an essential group leading to phonation disturbances. In recent years essentially new surgical approaches have been initiated in the management of these pathologies. It is assumed that voice function quality is dependent not only on the nature, extent and site of the pathology but, also on the technique of the surgery employed and, consequently, on the degree of operative trauma. Contact laser excisions are, among modern sparing methods of laryngeal surgery. It has been shown that contact laser methods are more advantageous as compared to conventional surgery. The present investigation is aimed at exploring phonation in patients with various laryngeal pathology after Nd:YAG contact laser surgery.
