Introduction: Supracricoid laryngectomy with cricohyopexy (CHP) and cricoepiglottopexy (CHEP) are the one of functional laryngectomy.

Aim: The aim of the study is phonation assessment of the reconstruction larynx. Material and methods. The examined group consisted of 58 patients (49 males and 9 female). An average age 54. 32 patients underwent CHP and 26-CHEP CHP was performed in following modes: a) 1 arytenoid cartilage left in 17 cases, b) 2 arytenoid cartilages left in 14 cases and c) 1 arytenoid cartilage left and second was resected with subsequent reconstruction in 1 case. The arytenoid cartilage was reconstructed in 19 cases (8 after CHP and 11 after CHEP). The vascularized thyroid lobe was used to the reconstruction of arytenoid cartilage in 8 cases (6 after CHP and 2 after CHEP), cuneiform or corniculate cartilage was used in 4 patients (1 CHP and 3 CHEP) and mucous membrane in 7 cases (1 CHP and 6 CHEP).

Result: Socially efficient speech was found in 74% patients and the results were better after CHEP.

Conclusion: The phonetic-acoustic structure of voice and resonant speech was considerably different from the phonetic-acoustic structure of voice and speech under physiologic conditions. These differences applied to segmental (formant structure, frequencies, noise range), as well as suprasegmental voice features.
