Identification by frontal sinus pattern in forensic anthropology

The authors report forensic cases from the literature, as well as two personal homicide cases, of identification through comparison of frontal sinus radiographs. A general discussion about identification using frontal sinus X-rays is presented, pointing out the reliability of the method, in reference to the uniqueness of the frontal sinus in humans, but also some difficulties, especially in reference to the distance, orientation and angle of the X-ray technique.
