ABSTRACT
In most of the surviving patients after a lightning strike, audiovestibular abnormalities have been reported. The most frequently reported type of abnormalities is a tympanic membrane perforation with hearing loss and external ear canal burn. However a sensor neural hearing loss and mixed type hearing loss can also occur, but these occur rarely. A nineteen-year-old female patient had, after a lightning strike, serious burns on the left ear, behind the ear, and on the chest and neck. She also had in her left ear 108 dB hearing loss with irregular central perforation and in her right ear 52 dB sensorineural hearing loss. There was no hearing loss before the strike. A hearing aid was recommended for the right ear and good care and follow-up were recommended for the left ear. A lightning strike can cause serious audiological damage. Therefore, it is necessary to make a careful audiovestibular evaluation of the patients. Although there exist rarely healed cases from sensorineural hearing loss after lightning strike in literature, in our case hearing loss occurred bilaterally and then it healed unilaterally. This condition is quite rare in literature.

Mentions: A nineteen-year-old female patient, after being struck by lightning, came to the emergency room with burns on her body and somnolence. To observe the possible cardiac risks and for the treatment of burns on the body, the patient was treated in intensive care for eight days, and she applied to our otolaryngology clinic because of hearing loss ten days after lightning strike. It is written in her medical history that she had no hearing loss before the lightning strike and she cannot remember the case. During the physical inspection, right external auditory canal and tympanic membrane and the left external ear canal are examined as a normal. On the left tympanic membrane, about 5 × 4 mm perforation was determined (Figure 1(a)). Walk, Romberg, finger-nose, and Unterberger tests were found to be normal and there was no nystagmus; nasal and otorhinolaryngology examinations are determined to be normal. Healed burn wounds are observed on the posterior skin of the left ear, left side of the neck, and sternum (Figure 2). Based on these findings, we thought that lightning struck the left side of the body. During the pure tone audiometric on the left ear at 108 decibels (dB) and on the right ear 52 dB (average of hearing threshold in 500, 1000, and 2000 Hz frequencies) sensor neural hearing loss was determined (Figure 3). Magnetic resonance imaging of the cranial region was determined naturally. Additional pathology was not observed so, for the rehabilitation of the hearing, a hearing aid was given for the right ear. Protection principles were explained for left ear and regular follow-up was recommended. During the pure tone audiometric by the 2-year follow-up of the patient, the hearing loss on the right ear was 17 dB (average of hearing threshold in 500, 1000, and 2000 Hz frequencies) and there was no change in the severity of hearing loss in the left ear. On the other hand, hearing loss was continuing in high frequencies in audiogram (Figure 4). There were no changes on the size of the left tympanic membrane perforation. Patient did not accept the myringoplasty operation, which was recommended by us. Due to convalescence on her right ear, the use of hearing aids was terminated.
