This is a form of catarrhal deafness with all the characteristic
pathology of the first or second stage, but in which, due probably
to sudden tubal occlusion, there results a marked variation in the
intralabyrinthine pressure and there are, therefore, the symptoms of
conduction deafness combined with labyrinthine involvement somewhat
resembling Meniere’s disease. There is dizziness or even vertigo,
with head noises, but not the marked prostration and nausea which
characterizes Meniere’s disease.
=Treatment.=—The treatment is the same as in the first stages of
catarrhal deafness and the prognosis is always good. The labyrinthine
symptoms are usually completely relieved as soon as the middle ear is
ventilated.
