<prompt> Most potential route for transmission of Meningitis from CNS to Inner ear is:Cochlear AqueductEndolymphatic sacVestibular AqueductHyls fissure  <response>: Most potential route for transmission of Meningitis from CNS to Inner ear is Cochlear Aqueduct. The scala tympani is closed by secondary tympanic membrane; it is also connected with the subarachnoid space through the aqueduct of cochlea. Hence the infections from meninges can spread to inner ear.
