Cold knife (steel) dissection is the oldest tonsillectomy method in use today. In this subcapsular method, the tonsils and/or adenoids are removed completely using a scalpel.

How it works

In the cold knife procedure, the surgeon grasps the tonsils or adenoids with forceps and cuts away the tonsillar tissue with a stainless steel scalpel or scissors. Bleeding is controlled by applying pressure with small cotton plugs or rolls, stitching, or electrocautery.

Advantages Less post-operative pain: Cold knife dissection is typically less painful than electrocautery. Cost: Cold knife dissection is less expensive than other methods.

Disadvantages Blood loss: The cold knife method may result in more blood loss during and after the tonsillectomy operation. Time: The cold knife method may take longer due to increased time to control bleeding.
