Brief Summary
The diagnosis and treatment of tonsillar abscess are very physician-dependent, as sufficient prospective medical literature is lacking to choose the most efficient regimen. The proposed study aims to assess the therapeutic efficacy of tonsillectomy compared to drainage under local anesthesia. This is a prospective, randomized clinical trial in adults in a tertiary care center in Geneva (Switzerland).

Outcome Measures
Primary Outcomes (1)

3 days
Secondary Outcomes (1)
Recurrence rate (%)
3 and 12 months
Study Arms (2)
Incision drainage
ACTIVE COMPARATORAdult with clinical suspicion of tonsillar abscess who underwent a CT-scan confirming the abscess will be randomly assigned to one arm or the other. "Incision drainage" arm will benefit from drainage of the tonsillar abscess under local anesthesia and then be hospitalized for intravenous antibiotics. If the incision drainage fails, they will get a tonsillectomy under general anesthesia.
Tonsillectomy
ACTIVE COMPARATORAdult with clinical suspicion of tonsillar abscess who underwent a CT-scan confirming the abscess will be randomly assigned to one arm or the other. "Tonsillectomy" arm will benefit from tonsillectomy under general anesthesia and then be hospitalized for intravenous antibiotics.
Interventions
Oropharyngeal pre-anesthesia is performed with 10% xylocaine spray, then submucosal anesthesia of the anterior pillar of the tonsil is performed with 2 ml of Rapidocaine or Rapidocaine 1 or 2% adrenaline. A scalpel incision is made with the search for the abscess pocket with a crile. If pus is present, a NaCl / Betadine rinse is performed. A syringe puncture can help locate the abscess if needed. The duration is approximately 15 minutes. If no purulent pouch is found, the procedure is completed with tonsillectomy under general anesthesia.
Under general anesthesia, in dorsal decubitus, an autostatic mouth opener is placed, an incision of the anterior pillar of the tonsil allows the opening of the capsular space, along which the entire tonsil is dissected until complete extraction, hemostasis is performed, then the patient is awakened. The duration is approximately 30 minutes.
Eligibility Criteria
You may qualify if:
- Patients ≥18 years of age with clinical suspicion of unilateral tonsillar abscess without signs of "extra-capsular" complication.
- Obtaining informed consent.
You may not qualify if:
- Contraindications to injected CT or drainage in local anesthesia (allergy to iodinated contrast product, allergy to local anesthetics, phobia of needles, major trismus).
- Parapharyngeal or retropharyngeal abscess, or associated venous thrombosis found on CT.
- Imminent threat to the upper respiratory tract (glottic edema, acute dyspnea).
- Inability to understand the different procedures (dementia, impossible communication, substance abuse).
- Anamnestic pregnancy.
- Antiaggregant or anticoagulant treatment.
- Treatment of corticosteroids during the management of emergencies and in hospital.
