title: [Suppurative middle ear infection as a complication after tympanostomy tube placement].
abstract: BACKGROUND
  Suppurative otitis media after tympanostomy tube placement is the most frequent complication of this surgical intervention. Otorrhea that occurs in the first two weeks following tube placement is called early, late otorrhea occurs at least two weeks following placement. Early otorrhea is usually a result of either an infection that already existed when the tube was placed, or contamination of the external auditory canal during operation. Late otorrhea is mostly a result of upper respiratory tract infection.
  
  
  METHODS
  Our investigation was performed at the ENT Department, Mother and Child Health Care Institute in Belgrade. The research included children treated for secretory or recurrent otitis media.
  
  
  CONCLUSIONS
  We have examined 411 children implanted with 796 tympanostomy tubes in the last three years. We investigated changes within two weeks after operation. Suppuration was recorded with 81 children (19.7%). Staphylococcus aureus was established in 33 (40.7%) Pseudomonas aeruginosa in 26 (32%), Haemophilus influenzae in 12 (15%) and Streptococcus pneumoniae in 10 (12.3%) cases. All children were treated with antibiotic ear drops according to the antibiogram for a period of 7 days. Full recovery was achieved after treatment with Ciprofloxacin drops in 67%, Neomycin in 18% and Gentamycin in 9% of cases. In other cases a combination of drops and oral antibiotics was used.
  
  
  CONCLUSIONS
  In cases of suppurative otitis media after implantation of tympanostomy tubes, the secret should be treated with suction and after that antibiotic drops should be applied during 5 to 7 days. If suppuration is persistent, drops should be used with oral antibiotics.
