title: Bilateral vocal cord paralysis following radiation therapy for nasopharyngeal carcinoma.
abstract: Cranial nerve palsies are uncommon late sequelae of radiation therapy. We present a rare case of bilateral vocal cord paralysis secondary to radiation-induced recurrent laryngeal nerve paralysis. The exact mechanism accounting for radiation-induced nerve damage is unknown. The complication may occur years following radiation therapy thus making a causal relationship difficult. As there is no treatment available, the therapy should aim to improve the functional impairment produced by the nerve involved.
