Suppressed sneezing as a cause of hearing loss and vertigo.
Two cases of inner ear injury caused by suppressed sneezing are described. One patient experienced vestibular symptoms in the form of reflexogenic vertigo that was relieved by surgical section of the tensor tympani tendon. The other patient had a sudden severe permanent sensorineural hearing loss. It is proposed that the aerodynamic pressure increase associated with suppressed sneezing is transmitted via the eustachian tube to cause an implosive fistula of either the round or oval window with injury to the membranous labyrinth.
