Can the drill penetrate the inner table?
One report of cadaveric craniums has suggested that patients with thin or fragile bones may be at risk for full thickness penetration. This is why such situations represent a clear contra–indication to the use of this device. To reduce the risk, the Company recommends that the holes be drilled anterior to the coronal suture and medial to the temporal fusion lines (but away from the sagittal suture). Here, the bone appears to be the thickest.
