Abstract:
Voice quality was analysed in 39 patients with the larynx carcinoma after the supraglottis subtotal laryngectomy. Voice pattern was analysed with the use of subjective and objective spectrography before and after the surgery. A deteriorated voice quality was found after the surgery. The spectrographic examination revealed decreased frequency levels of the formants F3 and F4 and the presence of a noise component generated in the glottis area.
