Facial impact tolerance and response.

face (human)- impact test (veh)- cadaver- human tolerance- fracture (bone)- injury- severity (accid.injury)- force- acceleration- Facial impact experiments were conducted on eleven unembalmed human cadavers. A 32 kg or 64 kg impactor with a 25 mm diameter, rigid cylindrical contact surface was oriented in the left-right direction relative to the face and contacted the nose at the elevation of the infraorbital margins. While the threshold for nasal bone fractures van not determined, it appears that a peak force of about 3 KN (filtered 180 Hz) is a representative threshold for more severe fracture patterns.
