title: Bilateral vocal fold paralysis: an unusual treatment with botulinum toxin.
abstract: We presented a patient with bilateral vocal fold paralysis treated with intralaryngeal Botox injection to improve the glottal airway. The use of Botox in this manner has not been previously reported and highlights the value and role of intralaryngeal Botox in changing the configuration of the glottis. The concept and various approaches for using Botox to alter pathologic vocal fold position is reviewed and discussed.
