Background and Objectives:Bilateral vocal cord paralysis is a potentially life-threating problem, but it acompanies a relatively rare complication of acute cerebral lesions. We attempted to estimate the usefulness of radiologic studies as predi-ctive factors of recovery from this condition. Materials and Method:Five patients who developed acute respiratory failure after acute ischemic stroke were included in the study and followed up. Radiologic studies (CT or MRI)localize the brain lesions. Bilateral vocal cord paralyses were confirmed by rigid or fiberoptic laryngoscopy. Results:Re-covery of vocal cord mobility was observed in three patients. Vocal cord paralysis was not resolved in two patients with lateral medullary infarction and large subcortical infarction. Conclusion:Bilateral vocal cord paralyses resulting from acute cerebral lesions have diferent prognoses according to their location and extent. Therefore, radiological studies may be useful (Korean J Otolaryngol 2002;45:608-12)
