Abstract
BACKGROUND: Tonsillectomy remains a common procedure in Germany. However, demographic changes, the advent of tonsillotomy, and current guidelines may have an impact on the overall incidence. OBJECTIVE: To longitudinally evaluate the number of tonsillectomies, with (ATE) or without adenoidectomy (TE), and tonsillotomies (TT) performed annually in Germany. MATERIALS AND METHODS: Based on comprehensive data from the Federal Office for Statistics, the number of patients undergoing the above-stated surgical procedures on an inpatient basis was retrospectively assessed in terms of year and federal state, without restriction by age or gender. Annual rates of ATE, TE, and TT were calculated based on population statistics. Regression analysis was performed to compare different federal states, years, and age groups. The variables were compared using the Pearson correlation coefficient. RESULTS: Between 2005 and 2017, 1,313,449 tonsil surgeries were registered. There was a considerable decrease in the overall incidence rate (per 100,000) of TE (92 to 43), which was even more pronounced for ATE (51 to 15). In contrast, an increased TT rate (6 to 22) was observed. Correlation analysis revealed a strong positive correlation (r = 0.986). CONCLUSION: The change of trends in tonsil surgery started long before relevant national guidelines were published. The national trend was associated with considerably less surgical activity overall, a significant decrease in ATE/TE, and a significant increase in TT. Regional differences to the national trend were identified and found to be significant in at least in 7 of 16 federal states.
