All phonomicrosurgery procedures were conducted at the Department of Otolaryngology at the CM UJ in Kraków. For electroglottographic analysis the following were used: mean irregularity factor for the word "ola", and the voice profile for the vowel "a" using the mean parameter of glottis closure Qx - mean, mean frequency of glottis tone - Fx mean, Jitter factor first mean and Schimmer factor plus mean. In electroglottographic assessment after the phonomicrosurgical procedures stable improvement of the phonation function of larynx.
