ABSTRACT
Syphilis is a well established cause of hearing loss. Sensorineural hearing loss may develop in the congenital or acquired form. The clinical course of the early acquired and late congenital forms are similar: sudden or rapidly progressive bilateral sensorineural hearing loss with mild vestibular symptoms. Cochleovestibular involvement in early acquired syphilis has been related to a basilar meningitis with lymphocytic infiltration of the labyrinth and VIIIth nerve. However, neurosyphilis and inner ear syphilis are not the same disease. Prompt diagnosis and treatment with corticosteroids and penicillin are mandatory to reduce the immune response and fibrosis of the labyrinth and the endolymphatic sac. Unfortunately, early acquired syphilis is frequently overlooked in the differential diagnosis of other forms of sensorineural hearing loss, particularly autoimmune inner ear disease. Given the increasing number of luetic infection cases, especially in immunocompromised patients, this condition should be considered in any sexually active patients affected by sudden hearing loss. Cases of inner ear syphilis are presented. Immunopathology of luetic inner ear infection is discussed and compared with immune disorders of the inner ear.

Tuberculous otitis media (TOM) is a rare cause of chronic suppurative infection of the middle ear. Due to that the symptoms and signs are often indistinguishable from those of nontuberculosis chronic otitis media and the fact that the index of suspicion is low, there is frequently a considerable delay prior to diagnosis. This can lead to irreversible complications such as facial nerve paralysis and labyrinthitis. Medical therapy with antituberculous drugs is usually effective. We report three cases with TOM diagnosticated and followed up in our Service from january 1993 to july 2001. Their charts were retrospectively reviewed for relevant historical data, physical findings, complementary studies, treatment and clinical response. We performed a review of the literature, emphasizing that TOM should be considered in the differential diagnosis of chronic otitis media.
