ObjectiveThis study aims to evaluate long-term complications after tonsil surgery using an exploratory retrospective cohort study design based on data from the Swedish Quality Register for Tonsil Surgery (SQTS).MethodsAll patients registered in the SQTS between 1 January 2009 and 31 May 2021 were eligible for the study. In this study, a long-term complication is defined as any complication persisting for a minimum of 6 months after surgery. The definition of a complication was based on individual patient reports, provided in a free text format, of any remaining issues 6 months after tonsil surgery. Complications were categorized as follows: disturbed taste or sense of smell, dysphagia, miscellaneous and general symptoms and signs, miscellaneous throat problems, pain or discomfort in the mouth or throat, problems with jaws or teeth, problems with the ears or hearing, problems with the nose or sinuses, problems with throat secretions or throat clearing, problems with voice or speech, and sensory symptoms. A multivariable logistic regression analysis was used to identify independent predictors of long-term complications.ResultsIn total, 54,462 patients were included in the study. A total of 3,780 patients (6.9%) reported one or more long-term complications. The most frequent long-term complications, with a plausible connection to the surgery, were found in the following categories: pain or discomfort in the mouth or throat (1.9%), problems with throat secretions or throat clearing (0.8%), dysphagia (0.6%), and problems with voice or speech (0.6%). Tonsillotomy was associated with a lower risk of long-term complications than tonsillectomy.ConclusionThis study suggests that subjective long-term complications after tonsil surgery, in general, are relatively common (6.9%). However, complications with a plausible connection to the surgery were less common (4.0%), and specific complications seemed to be relatively rare, with no single specific problem reaching a prevalence of ≥0.6%.
