Voice analysis after the partial laryngectomy in patients with the larynx carcinoma.

The paper presents 170 cases of patients with the larynx carcinoma after the partial laryngectomy. According to the procedure which we used, vertical, horizontal and subtotal supraglottis laryngectomies were distinguished. Voice pattern was analysed with the use of subjective and objective spectrography. The lowest degree of dysphonia was found in patients after the horizontal laryngectomy, while the highest degree dysphonia in those after subtotal supraglottis laryngectomy.
