Background and Objectives : The otologic clinical spectrum of electrical injuries include external, middle and inner ear damage especially sensorineural hearing loss due to inner ear damage is irreversible and causes permanent disability. Therefore, we investigated clinical manifestations and progress of inner ear damage by electrical injury.
Methods: A review of 64 patients with otolaryngologic consultation after electrical injuries who admitted to Hangang Sacred Heart Hospital over January 2000 to December 2006 was done. 20 Patients with tinnitus, hearing disturbance after electrical injuries were evaluated by audiometric tests (pure tone audiometry, speech audiometry, tinnitogram, auditory brain response).
Result: All were males, with mean age of 46 years. 5 patients complained bilateral tinnitus without hearing loss, 15 patients showed sensorineural hearing loss (SNHL) in pure tone audiometry with tinnitus；bilateral and unilateral 14 to 1 respectively. In the 15 SNHL patients, only 1 patient showed slightly improvement and the rest showed no significant improvement.
Conclusion: Electrical injury can cause serious disabilities such as sensorineural hearing loss and tinnitus.. Therefore, early otologic evaluation and management were needed in patients with electrical injuries.
