Combined use of frontal sinus and nasal septum patterns as an aid in forensics: A digital radiographic study

Abstract

Background:Skull radiographic examination is a potentially useful procedure for the personal identification in cases where fragments of skull persist with no likelihood of identification based on dental arch.Aims:The study was to determine the uniqueness and reliability of combined frontal sinus (FS) and nasal septum (NS) patterns as observed on posterioanterior (PA) cephalograms for personal identification.Materials and Methods:The randomly selected 149 digital PA cephalograms taken on Kodak 8000C Digital Panoramic and Cephalometric system were evaluated for patterns of FS and NS. Also the distribution of lobulations, area, and ratio of height/width of FS was calculated. The data obtained was statistical analyzed using Pearson's coefficient correlation.Results:FS symmetry was observed in 78.5% and asymmetry in 7.3% subjects. Bilateral aplasia was noticed in 5.3% and unilateral aplasia in 8.7% of subjects. The total lobulation of FS was noted more in males on both sides while center lobes were observed slightly more in females. The straight NS was maximally seen followed by reverse sigmoid. The mean ratio of width/height of FS was observed more in males and highly significant correlation was observed with both sexes. The mean area of FS was noted more in males. There was significant correlation found between patterns of NS and FS except in right dominated asymmetrical FS.Conclusion:The combined use of FS and NS patterns could be used as method for identification by exclusion in forensics.

Personal identification using frontal sinus and nasal septum patterns in forensic medicine: A retrospective digital radiographic study

“…[6,16] Unilateral aplasia was found in 5.7% which was in total contrast with Verma et al as 8.7% and Gopal et al (2016) as 2.5%. [16,17] In the present study, the patterns of NS were observed as straight as 33%, right deviation as 21%, left deviation as 14%, and sigmoid as 33% which was in total contrast with the studies done by David and Saxena as 22%, 42%, 30%, and 2%, respectively, and by Taniguchi et al as 13.4%, 37.6%, 35.3%, and 6.3%, respectively. [4,6] The gender distribution was found to be male dominant in all the patterns of FS and NS except in case of bilateral aplasia in which female dominancy was observed which was in total contrast with the study done by Verma et al where although equal distribution of NS and FS was present except in right dominated asymmetrical FS and Reddy et al where males and females were equally distributed.…”

Morphometric Evaluation of the Frontal Sinus and Nasal Septum as an Aid in Personal and Gender Identification- A Retrospective Digital Radiographic Study

“…In our study, males and females were equal in number i.e 70 males and 70 females (50% each), which is similar to the studies conducted by Verma K et al (2017) 4 15 . In contrast to these, 150 males and 130 females were taken in study published by Nagarj T (2017) 16 and 74 males and 75 females were enrolled in study published by Verma P et al (2015) 7 . In Cakur B et al (2011) 17 study, 190 males and 220 females were included.…”

“…The combined patterns were noted for each radiograph. 7 The results were analyzed using Statistical Package of Social Sciences (SPSS) software version 21. The dimensions of FS between males and females were compared using paired t-test.…”

“…(Figure 1). 7 Based on the symmetry, FS was classified as symmetrical or asymmetrical (right orleft dominant), along with unilateral or bilateral aplasia ( Figure 2). The right and left side difference in dimensions of FS was divided by their greatest dimension and was multiplied by 100.…”

The age-dependent changes of sella turcica, frontal and sphenoid sinuses

“…Неповторимая индивидуальность строения ЛП отмечена многими иссле-дователями [20,22,41,42,[44][45][46][47][48][49], что позволяет прово-дить достоверную идентификацию личности при сравне-нии прижизненной и посмертной рентгенограмм черепа. S. Reddy [45] и P. Verma [42] при комплексной оценке морфометрии перегородки носа и ЛП выявили суще-ственную корреляцию, которая может быть использована для идентификации личности в возрасте старше 20 лет. У мужчин линейные и объемные размеры ЛП больше, чем у женщин, причем преимущественно правая ЛП больше, чем левая, и у мужчин и у женщин.…”
