title: [Myasthenia preceded by dysphonia. Clinical and electrophysical study].
abstract: The solely dysphonia symptom as atypical and relatively rare onset of myasthenia gravis is difficult to diagnose. We present 11 cases of myasthenia, where dysphonia was one and only one symptom of illness during several months to several years. The evidences of dysphonia were the fatigability and nasality of speech, as well as chronic hoarseness. The diagnosis of myasthenia was very difficult in this period and was often preceded by lengthy laryngological and neurological examination. In our paper we present the criteria proper for myasthenia diagnosis in which repetitive electrostimulation test and high-sensitive SFEMG method are used.
