 A 72-year-old woman was referred to our hospital after earpick-induced trauma, presenting with hearing loss in her left ear and dizziness. A perforation was observed in the posterior-inferior quadrant of the left tympanic membrane. A perilymphatic fistula and foreign body were suspected in the round window. Emergency surgery revealed a small wooden fragment penetrating the cochlea through the round window membrane. Removal of the foreign body followed by sealing of the round window and myringoplasty was performed. The vertigo and dizziness subsided after the surgery;however, her left ear hearing loss remained irreversible. Early surgical management should be considered in patients with perilymphatic fistula caused by direct trauma.
