Ventricular dysphonia following long-term endotracheal intubation: a case study.

Although dysphonia following long-term endotracheal intubation (EI) is a common complication, no cases of ventricular dysphonia have been reported. This investigation reports a case of persistent ventricular dysphonia following a 12-day intubation period. The patient received eight sessions of voice therapy employing the manual, laryngeal musculoskeletal tension reduction procedure. Improvements in perceptual, acoustic, and videolaryngoendoscopic measures of voice production are reported. Mechanisms contributing to the development, maintenance, and resolution of ventricular dysphonia are discussed.
