title: Pseudomonas aeruginosa meningitis following stapedectomy.
abstract: Meningitis is a rare complication following stapedectomy.  Most cases are preceeded by a fistula in the oval window.  Although fatalities have been reported, most cases respond to parenteral and intrathecal antibiotics if diagnosed and treated early.  Gram-positive organisms are the usual pathogens, but Gram-negative organisms may be found, especially as a superinfection following antibiotics administered prophylacticly or for the treatment of otitis media or mastoiditis.  A case of Pseudomonas aeruginosa meningitis five weeks after stapedectomy, successfully treated with gentamicin, is reported.  The discussion included the diagnosis of post-stapedectomy fistula and meningitis and current trends in treatment.
