Sudden deafness is known to be a disease that typically does not relapse.
Consequently, although some relapsed cases have benn previously reported, they are very few. We present a report on 2 rare cases of relapsed sudden deafness.
Case 1: A 53-year-old woman with successfully treated sudden deafness showed acute perceptive deafness localized in the same ear 4 months after therapy.
Case 2: A 38-year-old man with cured sudden deafness showed, similarly to case 1, acute perceptive deafness localized in the same ear 2 weeks after therapy.
Interestingly, whereas therapy for relapsed deafness in case 1 was successful, it was not effective in relapse in case 2. In both cases, audiograms showed identical symptoms of incipient and relapsed disease.
The cause of different progression and therapeutic response in relapsed disease in these cases remains unclear.
