“…This is similar to other reports [5,10,[23][24][25][26][27][28] but contrary to study by Ariji et al which reported no significant difference between the genders [21]. Our study shows that generally, the left FS has higher dimensions than the right which is similar to other reports [29][30][31][32], but in contrast to another study done in India in which the right FS has higher values [27]. Furthermore, this study shows a positive correlation between left FS height and age.…”

Background: Radiological identification is important in clinical, surgical and forensic medicine particularly in the absence of comparative deoxyribonucleic Acid (DNA) samples and fingerprints. Aim is to establish the morphometry of frontal sinus (FS), maxillary sinus (MS) and bizygomatic distance (BZD) and their relationship with age and gender in Igbos and Ogonis of Nigeria using computed tomography (CT). Methods: Head CT scans of 625 subjects (477 Igbos and 148 Ogonis) between 18 and 85 years, showing normal FS, MS and BZD, were measured using DICOM viewer software. The Igbos and Ogonis were 247 males and 230 females; 84 males and 64 females respectively. The height, width and depth of the sinuses, intermaxillary sinus distances (IMD) and BZD were measured in centimeters (cm). The data were analyzed using SPSS version 20 and difference between groups was obtained using one way ANOVA. P-value less than 0.05 was considered as statistically significant. Results: Mean values for the right and left MS volume for the Igbos are 13.79 ±10.91 and 13.81±11.03 and for the Ogonis 20.84±5.83 and 20.19±5.59 cm respectively. All FS dimensions are higher in the Igbos (P<0.001) except right FS depth. Mean IMD are 3.64±0.50 and 3.39±0.45 cm in the Igbos and Ogonis respectively (P<0.001). Ogonis have higher BZD (P>0.05). In both groups, males had larger values in both FS depth, MS dimensions and BZD (P<0.001). Age correlated positively with left FS height and IMD. Prevalence of unilateral FS aplasia was 3.35% on the right and 1.47% on the left among the Igbos while the Ogonis have 2.03% on the right and 2.70% on the left. Bilateral FS aplasia was 2.94% among the Igbos but not observed among the Ogonis. Conclusion: Normative values is established. Ethnic differences exists with Igbos significantly having higher values of FS and IMD while in the Ogonis, the MS dimensions are higher. These findings would act as a guide for facial reconstructive surgeries, forensic experts and classification of fossil remains in anthropology.

“…20 A recent study from the same group reported that FS size in females increased with age, whereas FS size in males decreased after the age of 50 years. 36 Regardless of age and gender, we found that FS morphology does not progress in the same direction as craniofacial structure development.…”

The Relationships Between Craniofacial Structure and Frontal Sinus Morphology: Evaluation With Conventional Anthropometry and CT-Based Volumetry

The purpose of this study was to investigate the effects of craniofacial structure and nasal septal deviation on frontal sinus morphology 3-dimensionally. This study of anatomy, anthropology, morphology, and radiology included 74 dry skulls as study sample. The craniofacial measurements were made through conventional anthropometric methods by the use of calipers. The nasal septal deviation measurements were done by computerized software on photographs taken from frontal view. Frontal sinus volumes were estimated by the computerized tomography-based volumetry. The relationships between craniofacial structure, nasal septal deviation, and frontal sinus morphology were tested by linear regression and correlation analysis. The analysis of numerical variables and categorical variables within different groups was done by Mann-Whitney U/Kruskal-Wallis, and χ2 tests, respectively. There appeared a positive relationship between the dimensions of the frontal sinuses and the maximal cranial length and the nasal height especially on the left side ( P < .05). However, after multivariate linear regression model for both factors was created, solely the nasal height kept being a positive factor for frontal sinus size as an independent variable. No statistical relevance was detected between the presence of metopic suture and frontal sinus morphology. Septal deviation itself affected frontal sinus morphometry, but the morphometry did not differ between the deviation side and the opposite side. In conclusion, the cranial structure does not affect the frontal sinus morphology but nasal structure affects. The true influences, among measured craniofacial elements, in relationship with the pneumatization of frontal sinus are appeared to be the nasal structure related.

“…In addition, the age of the sample was also a determining factor for effective identification, since the final configuration of the frontal sinuses is only reached after the age of 20. 20 However, Tatlisumak et al 29 explored the pattern of frontal sinus configuration according to age, based on the belief that the frontal sinuses continue to expand to a later age, due to other factors and the influence of mechanical chewing factors. 32 In this case, it was agreed that there is a decrease in the frontal sinus area from the age of 70 years old, 29 but from the analysis performed, it was observed that the authors concluded that new studies need to be performed with less limited samples and looking at different backgrounds.…”

“…Regarding the type of image exam selected, it was verified that more than half of the studies used PA (posteroanterior) radiography. [14][15][16][17]19,20,22,[26][27][28][29][30] Thus, it was noted that conventional extraoral radiography is still the most viable and most used in the research, also emphasizing the increasing use, but still at a smaller scale, of threedimensional imaging resources, such as concomitant computed tomography. 10,13,18 In relation to the methodologies and identification parameters of the frontal sinus, the largest number of analyzes used both quantitative and morphological parameters.…”

“…Among all the parameters used to measure and classify the frontal sinuses, height and width were widely used to obtain asymmetry indices. 10,14,15,19,21,26,28,30 In addition to asymmetry, depth values, 21 volume 10,21,29 , and the anteroposterior diameter of the frontal sinuses 25,29 were repeated in several articles from the present analysis.…”

Palavras-chave: Seio Frontal. Radiologia Forense. Odontologia Legal. Identificação Humana RESUMO Introdução: A identificação humana é o processo pelo qual se estabelece a identidade de um indivíduo por meio da comparação entre dados registrados em momentos diferentes. Tratando-se do crânio humano, as regiões mais utilizadas na individualização do mesmo são as áreas da sela túrcica, no osso esfenoide, as células mastoides e o seio frontal. Objetivo: O presente trabalho teve como objetivo, através de uma revista da literatura, identificar e descrever as principais técnicas desenvolvidas para a identificação humana, a partir de exames de imagens dos seios frontais, em virtude da contribuição em potencial da radiologia odontológica nesse contexto. Fonte de dados: Para isso, foi realizada uma busca bibliográfica, no PUBMED, a partir do uso das seguintes terminologias: frontal sinus, radiology e forensic. Foram incluídos os artigos publicados entre 2007 e 2017 e excluídos artigos de revisão de literatura, cartas e relatos de caso. Síntese dos dados: Em um total de vinte e três artigos selecionados analisou-se a amostra quanto à nacionalidade, homogeneidade, sexo e faixa etária dos indivíduos, além dos tipos de exames de imagem que constituíram essa amostra, seja de origem radiográfica ou tomográfica, e suas diferentes projeções e modalidades. Além disso, classificou-se a literatura quanto às diferentes técnicas e parâmetros empregados para a identificação, sejam eles quantitativos ou morfológicos. Conclusão: Através desta busca, conclui-se que o perfil da pesquisa científica mundial, voltada para a identificação humana através de exames de imagem dos seios frontais, utiliza amostras homogêneas, de ambos os sexos e ampla faixa etária, empregando-se majoritariamente a Radiografia Extra-oral Póstero-Anterior e parâmetros qualitativos e quantitativos para a identificação.
