Abstract
OBJECTIVE: Initial evaluation has shown that temperature-controlled radiofrequency submucosal tonsil reduction (Tonsil Somnoplasty) effectively treats obstructive symptoms of tonsillar hypertrophy with minimal associated discomfort and rapid return to normal activity and diet. This study assesses the effects of treatment over an extended follow-up period of up to a year.
STUDY DESIGN: Twelve adults with symptomatic chronic tonsil enlargement underwent an average of 1.5 treatments. Evaluation included periodic oropharyngeal airway measurements, and questionnaires on treatment morbidity and symptom improvement.
RESULTS: Data on 12 patients at 3 months and 6 months, and 5 patients at 1 year show sustained increases in oropharyngeal airway size (1.7 cm/3 mo, 1.8 cm/6 mo, 2.4 cm/12 mo) and reduction in obstructive symptoms (Epworth Score decrease of 70%/3 mo, 58%/6 mo, 67%/12 mo; snoring reduction of 81%/3 mo, 79%/6 mo, 78%/12 mo) without significant differences after 3 months. A second treatment reduced tonsil size but gave variable further symptom improvement.
CONCLUSION: The effects of Tonsil Somnoplasty are maintained on follow-up to 1 year.
