Abstract
Self-recording audiograms of sudden deafness in 54 patients were studied for the relationship between type of Jerger's classification, hearing loss at the initial examination, and prognosis of hearing loss. Type I of Jerger's classification was shown in patients with slight to profound hearing loss, whereas Type II + IV was shown more frequently in cases with profound hearing loss. Many patients of Types I and II were among those who recovered completely or markedly, while patients of Type II + IV were found more frequently among those who recovered or had unchanged hearing.
