Guarded burr for deepening of nasofrontal junction.
Appropriate deepening of the nasofrontal junction remains one of the most difficult parts of rhinoplasty. A guarded burr is introduced that provides a safe and effective means of deepening or creating a shallow nasofrontal groove. The burr has a special guard that prevents the cutting of soft tissue. The guarded burr is introduced in position through the routine elevation of the bridge soft tissue subperiosteally. The safety latch is used for orientation. With gentle movement along the line connecting the canthi, the desired amount of bone can be removed from the nasofrontal junction with little time consumed. It is important to avoid continuous friction, since this might result in significant heat production and thereby thermal injury to the soft tissue and fluid collection.
