A Clinical Study of Bilateral Vocal Cord Paralysis

Bilateral vocal cord paralysis can result in a loss of voice function, dyspnea and dysphagia, and hoarseness. Between 2003 and 2013, there were twenty-six patients (9% of all vocal cord paralysis cases) diagnosed with bilateral vocal cord paralysis at our hospital. Thyroid surgery was the most frequent cause. Lateralization of the vocal cord was undertaken in nine patients, and tracheotomy was performed in 21 patients. In nine cases that underwent a glottal abduction surgery, six were able to undergo closure of the trachea aperture. Securing the respiratory tract is the most important aspect of treatment. After securing the airway, it is necessary to determine the best treatment based on the lifestyle and the QOL of the patient, and their demand for deglutition.
