Tonsillectomy Does Not Reduce Upper Respiratory Infections: A National Cohort Study

by Hyo Geun Choi, Bumjung Park, Songyong Sim, Soon-Hyun Ahn

Objectives

The objective of this study was to compare post-operative visits for upper respiratory infections (URIs) between tonsillectomy and non-tonsillectomy participants (controls).

Methods

Using the national cohort study from the Korean Health Insurance Review and Assessment Service, 1:4 matched (age, sex, income, region, and pre-operative URI visit) tonsillectomy participants (5,831) and control participants (23,324) were selected. Post-operative visits for URI were measured from 1 to 9 years post-op. The equivalence test was used. The margin of equivalence of the difference (Tonsillectomy—Control group group) was set to -0.5 to 0.5.

Results

There was no difference between the tonsillectomy and control group in 1- to 9-year post-op visits (-0.5 Conclusion

Tonsillectomy does not provide a decrease in the number of post-operative visits for URI, and URI decreased over time whether or not a tonsillectomy was performed.
