Identification of unknown bodies by using CT images of frontal sinus

Morphometric Sexual Dimorphism of Frontal Air Sinus: ACT Study

“…These various parameters were compared with the earlier studies. Our study, correlates with the study of Tatlisumak E, et al [10] (2008) & Mathew KL, et al [11] (2010) in case of AP diameter, but not in Height & Width where there is significant male -female difference, that too male having higher values.In the present study, Volume of frontal sinus when compared between male and female, the readings of males are towards higher side as compared to females but, it is not significant. This correlates with Ponde JM, et al [12] (2008).…”

Usability of CT Images of Frontal Sinus in Forensic Personal Identification

“…Identification of human remains by comparison of antemortem and postmortem radiographs of frontal sinuses is a well established procedure among forensic scientists and even some of the authors claim to use them as a substitute for fingerprints and frontal sinuses in particular have always been assumed to be different in every person (Yoshino et al, 1987;Harris et al, 1987;Kullman et al, 1990). Computerized tomography is an advanced and new technique and in literature there are only a few reports on identification of unknown bodies using CT scans of frontal sinus (Reichs, 1993;Riepert et al, 2001;Tatlisumak et al, 2007;Pfaeffli et al, 2007;Blau et al, 2008;Uthman et al, 2010).…”

“…Thirdly, the resiliency of the frontal sinus makes it useful for forensic purposes. It has very strong walls and preserved intact in human remains (Marlin, et al, 1991;Nambiar, et al, 1999;Fairgrieve, 2008) Fourthly, paranasal sinus radiographs are taken commonly for diagnostic purposes and almost everybody has one in his/her health folder (Tatlisumak, et al, 2007;Cox, et al, 2009). Radiographic comparison permits the matching of unique anatomical features and has the advantage of making possible the matching of external and internal bony anatomy, therefore increasing by several-fold the potential number of points of correspondence available for identification (Jablonski & Shum, 1989).…”

“…But there are some disadvantages: Data can not be stored and the evaluation should be made again and again for every case and both radiographs should be in hands for comparison. To overcome this problem, systems were proposed for coding frontal sinuses (Yoshino, et al, 1987;Tatlisumak, et al, 2007;Cameriere, et al, 2008). But none of them is perfect and there is always a possibility of false positive results (Tatlisumak, et al, 2007;Tang, et al, 2009).…”

These systems are still are far from being as useful as fingerprints.…”
