Abstract		Background Laryngeal cancer is quite common in Slovenia. It represents 3 % of all malignant diseases in men. In approximately one third of the patients with laryngeal cancer, the malignant tumor appears on the vocal folds. In 80% of patients with glottic cancer, the disease is still in localized stage. The clinical definition of "early glottic cancer" comprises Tis, T1 and T2 tumors without metastases. While the treatment results of radiotherapy and surgery for early glottic cancer may be comparable, the functional results after radiotherapy are nevertheless better. Generally, the voice quality improves some months after the irradiation. In earlier works, some authors noted normal voice in the majority of the patients. However, because of the improvement of the diagnostic criteria and methods, the latest researches on voice quality of the irradiated patients report on abnormalities in almost all patients. The aim of the research was to assess objectively the quality of voices of the subjects irradiated for early glottic cancer and to compare it with the characteristics of the voices of healthy volunteers. Our aim was to identify the negative factors which influence the voice quality, in order to eliminate them and to improve the patient's voice. Subjects and methods. In the first part of the research, the results of acoustic analysis of the voice samples of 50 irradiated patients (44 men, 6 women) were compared to the analysis of the voices of 50 healthy age- and sex-matched volunteers. In the second part of the research, the group of patients who were irradiated for Tis, T1 or T2 tumors one to ten years ago increased to 76 subjects (69 men, 7 women).
