Tonsil surgery in Sweden 2013-2015. Indications, surgical methods and patient-reported outcomes from the National...

To describes how tonsil surgery was performed in Sweden from 2013 to 2015 with data from the National Tonsil Surgery Registry in Sweden (NTSRS).

The registry collects data from both professionals and patients through questionnaires. A total of 33,870 tonsil surgeries were analysed, comprising approximately 80% of all tonsil surgeries in Sweden from 2013 to 2015.

The two most common procedures were tonsillectomy (41%) and tonsillotomy with adenoidectomy (38%). Tonsillectomy was most commonly performed to treat frequent tonsillitis, while the main indication for tonsil surgery with combined adenoidectomy and for tonsillotomy alone was upper airway obstruction. The most commonly used techniques were cold steel (70%) for tonsillectomy/adenotonsillectomy and radiofrequency (79%) for tonsillotomy/adenotonsillotomy. Ninety-five percent of patients reported symptom relief after 180 d. Day surgery was utilised in 70% of the surgeries. The rate of readmission due to post-tonsillectomy haemorrhage was 5.1%. Male patients more often underwent tonsil surgery at preschool ages due to upper airway obstruction; in comparison, female patients to a larger extent underwent surgery in their early teens because of previous infections.

The NTSRS provides an opportunity to survey tonsil surgery in Sweden and to launch and follow up improvement programmes as desired.
