The aim the study was showed some spirometric and aerodynamic parameters of the respiratory system and of vicarious voice at laryngectomized patients, which were performed in plethysmographic cabin and by using of pneumotachometer. Clinical material stated 20 laryngectomized men, aged 45-77 years, who were divided into two groups (by Pruszewicz): A-well or very well speaking and B-bad speaking. The obtained results showed that laryngectomized well or very well speaking made bigger work of the respiratory system during vicarious voice than bad speaking ones. The well and very well speaking patients used twice (in case of consonants) and three times (in case of vowels) the volume of oesophageal-throat's air greater than bad speaking patients. Aerodynamic examinations in plethysmographic cabin allows for monitoring of vicarious voice at laryngectomized after operation and qualification some of ones for voice prosthetization in the aim of voice amplification.
