Abstract:

The frequency of maxillofacial battlefield injuries has steadily increased since World War II. While anecdotal reports from the Army aviation community credit maxillofacial shields MFSs with preventing aircrew injury during aviation mishaps, however no MFS exists to prevent combat-related maxillofacial injuries to ground Warfighters. MFSs that attach to combat helmets are being developed to provide facial protection to ground and mounted troops. An important consideration when developing maxillofacial protective devices is to achieve a balance between the protective coverage and the field of view FOV blockage induced by wearing MFSs. This study compared subjective and objective methodologies to measure the FOV of proposed MFSs. This evaluation showed that the use of objective methodology yield similar results compared to the subjective FOV methodology. The use of the objective FOV methodology will expedite the test and evaluation of future MFSs and give more accurate results by eliminating the variability induced by differences in subject responses.
