title: The relationship between repeat tympanostomy tube insertion and adenoidectomy.
abstract: OBJECTIVE
  To examine the relationship between adenoidectomy and repeat tympanostomy tube placement in the treatment of otitis media, and the relationship between potential risk factors for otitis media and repeat tympanostomy tube placement.
  
  
  METHODS
  Retrospective, cross-sectional analysis of consecutive patients undergoing tympanostomy tube placement at an academic/teaching hospital with 400+ beds. Utilizing an electronic billing database, patients less than 18 years of age undergoing tympanostomy tube placement between January 1, 2000 and December 31, 2007 were identified. Information regarding initial and repeat tympanostomy tube placement as well as potential risk factors for otitis media were extracted from medical records.
  
  
  RESULTS
  904 children were included in the study. Of the 780 children who initially underwent tympanostomy tube placement alone, 178 required additional tube placement; a repeat rate of 20%. Of the 90 children who initially underwent tympanostomy tube placement with adenoidectomy, only 6 required repeat tube placement, a statistically significant decrease in the incidence of repeat tympanostomy tube placement (95% CI, 0.056-0.334; p<0.0001). The presence of craniofacial anomalies and day care/school attendance were significantly associated with additional tube placement. Children between the ages of 4 and 10 showed a significant (p<0.0001) decrease in the risk of repeat tube placement when an adenoidectomy was performed at the initial tube placement.
  
  
  CONCLUSIONS
  Adenoidectomy performed at the first tympanostomy tube for the treatment of otitis media may decrease the risk of repeat tube placement, especially for children >4-10 years of age.
