    Abstract:
    Traumatic perilymphatic fistula due to luxation of the stapes into the vestibule caused by an earpick is an extremely rare situation. In order to treat such an injury, it is necessary to evaluate the extent of the damage and the actual condition of the middle and inner ear. However, it is difficult to obtain such precise information about the condition of the stapes prior to performing surgery. We report on a case of a traumatic perilymphatic fistula with luxation of the stapes into the vestibule that was diagnosed using multislice CT (MSCT). MSCT clearly demonstrated the presence of air in the vestibule (pneumolabyrinth), which indicated the presence of a perilymphatic fistula and the deep depression of the stapes into the vestibule. In order to seal the perilymphatic fistula and prevent middle and inner ear infection, surgery was performed on the portion of the stapes that remained in the vestibule. The patient has been free from vertigo and has exhibited some recovery of his hearing. We discuss the diagnosis along with other therapeutic problems that have been presented in the literature for traumatic perilymphatic fistula.
