Objectives: Objectives of this study were to review our experience in on otogenic brain abscess and its management by transmastoid drainage and compare the results. Materials and Methods: All patients with brain abscess secondary to CSOM presenting to our department from January 1997 to December 2010 were included in this study. All patients subjected to clinical, neurological, opthalmological examination and CT scan was done as an imaging modality. All patients managed by radical mastoidectomy or modified radical mastoidectomy and transmastoid drainage of brain abscess as neurosurgical facility not available. Results: Seventy-two patients in whom brain abscess secondary to chronic suppurative otitis media was diagnosed and has been treated since 1997 are presented. 85% of patients were below 20 years of age. More than 50% patients presented with more than one complication of chronic suppurative otitis media. 85% of patients were having extensive cholesteatoma and 15% patients were having extensive granulations in middle ear and mastoid air cells. 83% patients were having cerebellar abscess while 17% patients were having temporal lobe abscess. 80% of the pus culture was sterile while in 20% patients various microorganisms such as Proteus spp., Escherichia coli, Pseudomonas aeruginosa, Staphylococcus spp., and Streptococcus spp were cultured. Overall mortality in this series was 4.4%. Conclusion: In diagnosis of otogenic brain abscess CT scan with constrast is of immense help. Transmastoid drainage of brain abscess is a safe and effective method that can be performed by otologists in cases of otogenic brain abscess.
