Abstract

Failure of pulmonary ventilation capacity results in carbon dioxide (CO2) retention. When this produces loss of consciousness, it is called CO2 narcosis. Chronic obstructive pulmonary disease is a common cause of CO2 retention. Bilateral vocal cord paralysis is a typical disorder resulting in upper airway obstruction. However, bilateral vocal cord paralysis has been rarely documented in the chronic course of obstructive diseases related to the ear/nose/throat because its symptoms are relatively obvious. A 49-year-old man who complained of hoarseness and dyspnea for several years was diagnosed with bilateral vocal cord paralysis. CO2 narcosis occurred after tracheostomy and laser posterior cordotomy had been applied to relieve dyspnea. Details of the case are provided along with a review of the relevant literature.
