Sensorineural deafness in early acquired syphilis.

A 36 year old male developed bilateral sensorineural deafness as the chief manifestation of secondary syphilis. Cerebrospinal fluid showed pleocytosis. Treatment with penicillin and prednisone resulted in good recovery of hearing. Initial recovery seemed dependent on corticosteroids. Deafness can complicate acquired syphilis in both early and late stages of the disease and may be its sole manifestation. Early acquired syphilitic deafness is usually the result of a meningitis affecting the eighth nerve and responds well to treatment. These features are contrasted with those of late acquired syphilitic deafness.
