Finnish adenoidectomy and tympanostomy rates in children; national variation.
OBJECTIVE
To assess upper respiratory surgery rates in Finnish children and compare the rates of adenoidectomy and tympanostomy tubes in 2002 with the 1987 cohort.


METHODS
Descriptive study of national upper respiratory surgery in Finland in 1987 and 2002; adenoidectomies, tympanostomy tubes and combination of these two. Surgical rates were viewed in the light of child density and number of primary care physicians and otorhinolaryngologists.


RESULTS
Rates of adenoidectomy and tympanostomy tubes were highest in Western Finland and lowest in Eastern Finland (p<0.00001). Peak-age for adenoidectomy and tympanostomy tubes was in the second year of life. Surgery was most common in boys (p<0.00001). Both the numbers of otorhinolaryngologists and operations increased from 1987 to 2002; the largest surgery increase, 7.3%, was found in Western Finland.


CONCLUSIONS
Large national differences in rates of paediatric adenoidectomy and tympanostomy tubes in Finland propose that national guidelines have not had an impact on the selection of children for surgery.
