Long-term effectiveness of tonsillotomy versus tonsillectomy: A 12-year follow-up study.

Abstract

To evaluate the long-term effectiveness of tonsillotomy (TT) compared to tonsillectomy (TE) with respect to disease-specific quality of life (QOL), sleep-disordered breathing symptoms, throat infections, and rate of reoperations over a median follow-up period of 12years. All patients < 16years of age who underwent tonsil surgery between 2010 and 2011 at Helsinki University Hospital, Finland, were included in the study. In 2023, the patients answered a questionnaire concerning tonsil-related issues and a modified Tonsil and Adenoid Health Status Instrument (disease-specific QOL). Information about possible revisits and reoperations was gathered. The study population consisted of 189 respondents, of which 87 had undergone TT and 102 TE. The median follow-up was 11.8years in the TT group and 12.4years in the TE group. The disease-specific QOL was equally good in both groups. Throat infections had not been an issue for the vast majority of patients and occurred to the same extent after TT and TE. The majority of participants (79.0% TT, 86.9% TE) were satisfied with the surgery, with no significant differences between the groups. After TT and TE, there were only a few revisits due to tonsil-related problems, and the reoperation rate was 6.9% and 1.0%, respectively. Long-term clinical effectiveness of TT seems excellent. Compared to TE, with TT, equal disease-specific QOL can be achieved with a less invasive surgical method. Over a median follow-up period of 12-years, TT was not shown to be associated with an increased risk of tonsil infection problems.
