Using the cutting burr

Using the cutting burr end on will generate a lot of heat. It is slow and inefficient. The heat will damage surrounding structures including:

  • the bone itself and its viability, and
  • the facial nerve. Many facial nerves have ultimately been injured and facial movement lost because of heat transmission.
