How Much Brow Bone Projection Can Be Removed By Shaving?

Q: Dr. Eppley, I want to ask Dr Eppley 3 quick questions regarding brow bone reduction.

– what is the average bone thickness over the frontal sinus? 

– how much bone can we shave over the frontal sinus? (in mm)

– and what is the minimal bone thickness we can let over the frontal sinus?

 (without risks of tissue dying)

A:In answer to your brow bone reduction questions:

1) The average of the frontal sinus table in men is 3mms.

2) Since 1mm needs to be left, 2mms can be reduced by burring.

3) As stated in #2, 1mm.
