RESUMO
OBJECTIVE: To analyse the correlation between laryngeal vocal efficiency and nasalance for patients after vertical hemilaryngectomy. METHOD: The lately invented instruments, phono-laryngography and nasometer, which can objectively evaluate vocal function, were used to determine the laryngeal vocal efficiency and nasalance in 30 patients with laryngeal carcinoma treated primarily by vertical hemilaryngectomy. RESULT: The results showed that laryngeal vocal efficiency and nasalance have significant positive correlations in all subjects (r = 0.47). CONCLUSION: Change of laryngeal vocal function influence the value of nasalance.
