Background A second-opinion procedure was introduced for (adeno)tonsillectomy and tonsillotomy in 2018 by the Federal Joint Committee, due to the assumed high prevalence of both procedures. This study was conducted to quantify and analyze both types of tonsil surgery in Germany. Methods Data from the Federal Office of Statistics on the number of procedures and population size were used to calculate annual intervention rates between 2005 and 2017. Percentual changes in intervention rates compared to the previous year were calculated for Germany, for the total number of ENT specialists, for the ENT specialists of the federal states, and for four age groups (≤10; ≤20; ≤40; >40 years). Results Regression analysis revealed a significant decrease in (adeno)tonsillectomy and a significant increase in tonsillotomy in each investigated year ( p  < 0.001; exception: 2006 for adenotonsillectomy). Surgical rates of tonsillectomy and tonsillotomy decreased significantly with age ( p  < 0.001). There was no clear relationship between the density of ENT specialists in the different federal states and the number of surgical procedures. Conclusion There was no clear association between the surgical prevalence and the density of ENT specialists. The significant decrease in rates of (adeno)tonsillectomy began in 2005 and the tonsillotomy rates have been increasing since 2007, albeit without a compensatory effect. Both procedures are on the list of the 50 most frequently performed operations. The decreasing total number of both surgical procedures questions the value of a second-opinion procedure as suggested by the Federal Joint Committee. Tonsil surgery is significantly associated with young age (<10 years) and discussions on surgery rates must consider the age structure of the investigated population, since this is the most important influencing factor in tonsil surgery.
