Recurrent Tonsillitis

The goal of this study is to optimize the duration of sick leave and the usage of opioids following partial tonsillar surgery in adults by comparing the recovery after extracapsular tonsillectomy (ECTE) with recovery after intracapsular tonsillectomy (ICTE). An additional objective is to confirm that ICTE is as effective as ECTE when comparing TOI-14 scores after 12 months post-operatively. The main questions the study aims to answer are: * Is 10 days sick leave enough after partial tonsillectomy (ICTE)? * Are opioids needed at all after partial tonsillectomy (ICTE)? * Is ICTE as effective as ECTE when comparing TOI-14 symptom scores after 12 months from the surgery? Adult patients who are scheduled to tonsil surgery are randomised into 2 groups: ICTE and ECTE. Patients are blinded. Postoperatively they will answer structured questions about the recovery and effectiveness of the surgery. The last follow up survey is 60 months after the surgery.

This prospective, multicenter, randomized, double-blind, placebo-controlled, cross-over clinical trial will evaluate the efficacy and safety of Streptococcus salivarius Evol12® (Bactoblis® Evol) in reducing the recurrence and duration of acute febrile adenotonsillitis in children aged 3 to 11 years. Participants will receive either the probiotic or a matching placebo for 3 months, followed by a 7-day wash-out and a second 3-month treatment period with the alternative product. The study will assess changes in the incidence and duration of adenotonsillar episodes, antibiotic use, school absences, and sleep quality.
