Research Abstract

Fluid accumulation in the maxillary or sphenoidal sinuses is more common in drowning victims. Pearson's chi-square tests demonstrated that fluid accumulation in the maxillary or sphenoidal sinuses was associated significantly with drowning. However, as it is present in 65% of the non-drowning victims as well, the presence of fluid cannot be used to diagnose drowning. The absence of fluid can be used to virtually exclude drowning.
Both volume and density of fluid accumulation in the maxillary or sphenoidal sinuses differed significantly between the drowning and nondrowning cases, The observed difference may help forensic pathologists better diagnose the drowning cases.
Fluid density of the maxillary or sphenoidal sinuses in saltwater drowning cases was significantly higher than that in freshwater drowning cases.The observed difference may help forensic pathologists better diagnose the specific cause of death in drowning cases.
