       Traumatic perilymphatic fistula due to luxation of the stapes into the vestibule caused by an earpick is extremely rare.
      A 27-year-old female suffered severe dizziness and tinnitus in the right side after a traumatic injury obtained while using an earpick. We diagnosed her illness as traumatic perilymphatic fistula due to luxation of the stapes by using multislice CT (MSCT). The image of multi-planar reformation (MPR) especially demonstrated the luxation of the stapes into the vestibule.
      The traumatic perilymphatic fistula was observed conservatively, but the patient suddenly suffered severe hearing loss and dizziness after two months. Surgical treatment involving reduction of the stapes and closure of the perilymphatic fistula was performed. The patient has been free from dizziness, but the hearing loss was not changed.
      We discussed the diagnostic and therapeutic problems in traumatic perilymphatic fistula as seen in the literature.

Key words : traumatic perilymphatic fistula, luxation of the stapes, multislice CT
