Brief Summary:
Comparing the classical extracapsular tonsillectomy (TE) performed with electrosurgery to intracapsular approaches (SIPT) by coblation or microdebrider. The patient group is adults with recurrent or chronic tonsillitis

Condition or disease Intervention/treatment Phase
Tonsil Disease Tonsillitis Tonsillitis Acute Tonsillitis Chronic Procedure: tonsillectomy Not Applicable

Detailed Description:

Extracapsular tonsillectomy (TE) with monopolar electrosurgery is the most commonly used approach in adult tonsil surgery in Turku University Central Hospital, Finland.

In our study setting we are comparing intracapsular tonsillectomy (subtotal/intracapsular/partial tonsillectomy (SIPT) ) as the intervention group with extracapsular tonsillectomy as the control group.

SIPT is done with either coblation or microdebrider and TE with monopolar electrosurgery.

Indications for surgery are recurrent tonsillitis or chronic tonsillitis. The patient group is adults (16-65 years)

Safety, efficiency and cost-effectiveness are monitored in a prospective, patient-blinded and randomised study setting.

Primary Outcome Measures :
  1. Post-operative recovery [ Time Frame: 21 days ]
    Pain post-operatively after discharge as self-reported pain intensity over the past day. Each day is scored with the modified Brief Pain Inventory and recovery is achieved when pain score reaches preset values. Recovery speed defined as pain VAS-score 3 or less at rest; or pain VAS-score 5 or less without regular analgesics use. Daily questionnaire used: Brief Pain Inventory.

Secondary Outcome Measures :
  1. Analgesics use [ Time Frame: 21 days ]
    Need for analgesics postoperatively during 21 days. Measured as number of naprometin tablets/ day and the number of tramadol-paracetamol combination tablets/day.

  2. Post-operative bleeding [ Time Frame: 21 days ]
    Bleeding post-operatively at the ward or at any point during 21 days. Measured as 1-4 (1= bleeding, stopped spontaneously, no contact with staff; 2: Contact with ER, bleeding stopped without intervention; 3: Bleeding, needed intervention (packing, topical adrenalin, electrosurgical hemostasis; 4: Needed OR-time, blood transfusion, ward days

  3. Life Quality [ Time Frame: 6 months ]
    Quality of life as defined by the questionnaires: Tonsillectomy Outcome Inventory 14 "TOI-14" preoperatively and 6 months after operation;

  4. Residual tonsil tissue [ Time Frame: 6 months ]
    Residual tonsil measured right after surgery is completed and at 6 months follow-up.

  5. Revision surgery [ Time Frame: 5 years ]
    The need of revision surgery after tonsillectomy, recorded with questionnaire: Nordic Tonsil Surgery Register

  6. Throat problems [ Time Frame: 5 years ]
    Throat problems as described by the Nordic Tonsil Surgery Register at different time points postoperatively

  7. Life quality [ Time Frame: 6 months ]
    Quality of life as defined by the questionnaires: Glasgow Benefit Inventory "GBI" at 6 months after operation.
