RESUMO
Hanging is traditionally classified as complete, incomplete by the completeness of suspension and typical, atypical by the point of suspension and location of knot. It has been well known that the signs of hanging including subconjunctival petechiae are different according to the type of hanging. We evaluated the incidence of subconjunctival petechiae on 260 cases of hanging and classified the point of suspension and location of knot, ligature mark, and position on cases with subconjunctival petechiae. The subconjunctival petechiae was found in 33.6% of all cases, mostly seen in incomplete, atypical hanging. However, about 30% of incomplete, atypical hanging showed no definite subconjunctival petechiae. The patterns of location of ligature mark, type of knot, and position were somewhat different between positive and negative cases of subconjunctival petechiae in incomplete, atypical hanging.
