A physiologic study on respiratory handicap of the laryngectomized

Abstract: Lack of the upper airway function after laryngectomy creates unfavorable effects on the lower respiratory tract. The purpose of this study is to re-evaluate this relationship objectively. Respiratory function tests were performed on 13 laryngectomized patients. Pulmonary volumetry and ventilometry revealed increased RV and FRC, and decreased FEV1.0%, indicating evidence of obstructive changes in the lung, MEFV-recordings showed greater downward convexity than those of the normal at the lower volume level. The … Show more

“…This difference can be due to changes in the respiratory system (reduced vital capacity; functional residual capacity, and mean expiratory flow rate), change in source of vibration (glottis to neoglottis) following total laryngectomy, change in vibrating principles (mass, length, and tension), and respiratory compromise due to typical age-related changes (loss of elasticity; recoil forces and reduced muscular forces) [14,[35][36][37][38][39][40][41][42]. Hence, SNP values obtained from the direct and indirect measurement methods in TE speakers may not be comparable with SGP obtained from normal laryngeal speakers.…”

“…Alguns autores descrevem o uso de cânulas com cuff na traquéia 5,12 ou máscaras fixadas manualmente sobre o traqueostoma para conectar o paciente ao equipamento para avaliar a função pulmonar 2,11 . Entretanto, a introdução de uma cânula traqueal é geralmente desconfortável para o paciente e a vedação da máscara por sobre o traqueostoma geralmente apresenta vazamentos.…”
