Middle ear effusions and myasthenia gravis.
A case of ME effusion in a patient with MG is reported. The likely pathogenesis is of TVP muscle weakness causing Eustachian tube dysfunction. ME effusion should be suspected in a myasthenic complaining of sudden hearing loss. Tympanometry with measurement of the ME pressures and reflexes is a useful tool for assessing a myasthenic's response to treatment.
