The goal of this project is to provide medicolegal practitioners with a set of guidelines and important considerations for frontal sinus identification that will be developed based on a comprehensive analysis of previously published identification methods, including factors that may affect the accuracy of those methods (e.g., intra/inter observer reliability, image modality, sinus size/complexity, individual's age). Ultimately results indicate that visual assessment remains one of the most efficient, accurate, and reliable methods when utilizing the frontal sinus for positive identification.
