Detailed Description
The investigators aim to study if good surgical results can be achieved by intracapsular tonsillectomy with coblation while monitoring safety, efficiency and cost-effectiveness.
In adult tonsil surgery, the current practice in Finland is commonly extracapsular tonsillectomy with monopolar electrosurgery.
