Analysis of Frontal Sinuses for Personal Identification in a Chinese Sample Using a New Code Number

Abstract

The study of frontal sinuses for personal identification is a considered approach in the forensic field. In Yoshino's system, the frontal sinus patterns of a given person were formulated as a code number (codY) obtained by arranging the class numbers in each classification item. The aim of this work was to use a new code number (codC) with eight digits that includes other two continuous variables obtained as ratios SOR1 (left frontal sinus area/left orbit area) and SOR2 (right frontal sinus area/right orbit area), comparing the results with that of Yoshino. Digital radiographic images of the skulls of 150 Chinese people were analyzed. Spearman's partial correlation coefficients were evaluated between variables characterizing frontal sinus patterns. We used a maximum‐weight dependence tree for statistical analysis. Results demonstrated that codC significantly reduced the probability of having the same personal code number compared with codY. Our scientific approach results valid for personal identification purposes.

Frequency of the frontal sinus aplasia among Saudi Arabian population. A single-center retrospective case review

“…For instance, proper identification of subjects can be reached through comparing the frontal sinus radiographs ante-and post mortem, since these images are characteristic for each individual. 11,14,15 This method is not appropriate for cases with absent frontal sinus; thus, sphenoid sinus can be used along with other standard methods of identification. 11,14,15 On another hand, a better understanding of anatomical differences will assist neurosurgeons performing pterional or supraorbital operations, and lessens the complications due to the close relation of the sinus to the surroundings including orbit and frontal skull base.…”

The Effects of Cranial Orientation on Forensic Frontal Sinus Identification as Assessed by Outline Analyses

“…Comparisons can also frequently be made on fragmented or even burned remains. Specific methods for radiographic frontal sinus identification range from qualitative visual assessments [ 1 , 3 , 19 , 20 ] to the use of metrics and/or coded traits [ 7 , 8 , 17 , 21 , 22 ], and outline analyses [ 15 , 16 , 23 ]—all of which rely at least partly on sinus shape as defined by the presence of right/left sinus lobes, as well as the individual scallops and arcades that give the sinus their distinctive outlines.…”

According to the authors, this method is suitable for different groups of people.…”
