ABSTRACT
BACKGROUND AND OBJECTIVES:
Bilateral vocal cord paralysis is a potentially life-threating problem, but it accompanies a relatively rare complication of acute cerebral lesions. We attempted to estimate the usefulness of radiologic studies as predictive factors of recovery from this condition. MATERIALS ANDMETHOD:
Five patients who developed acute respiratory failure after acute ischemic stroke were included in the study and followed up. Radiologic studies (CT or MRI) were performed to localize the brain lesions. Bilateral vocal cord paralyses were confirmed by rigid or fiberoptic laryngoscopy.RESULTS:
Recovery 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 different prognoses according to their location and extent. Therefore, radiological studies may be useful for predicting the recovery of centrally originated bilateral vocal cord paralysis.
