Is insufficient pulmonary air support the cause of dysphonia in chronic obstructive pulmonary disease?

Objective: Optimal pulmonary air support is essential pre-requisite for efficient phonation. The objective is to correlate pulmonary and vocal functions in chronic obstructive pulmonary disease (COPD) to find out whether the reduced pulmonary function per se could induce dysphonia.

Methods: In this prospective case-control study, sixty subjects with stable COPD underwent evaluation of pulmonary and vocal functions.
