We report on three cases of patients whose primary symptoms of myasthenia g
ravis were related to the upper aerodigestive tract. Symptoms had been pres
ent unrecognized in all patients for up to three years, and one patient sub
sequently developed a myasthenic crisis. We highlight the clinical features
of myasthenia gravis to allow its prompt recognition in patients presentin
g to the ENT surgeon or physician.
