Publication The mandibular ramus flexure in the byzantine skeletons of nicea remains: A singular morphological indicator(Moravian Museum, 2006-01-01) Arı, İlknur; ARI, İLKNUR; Tıp Fakültesi; Anatomi Ana Bilim DalıLoth and Henneberg (1996) described the flexure of the posterior margin of the mandibular ramus at the level of the occlusal plane as a single morphological indicator of sexual dimorphism. Using only this feature, Loth and Henneberg were able to predict sex with 94.2% accuracy in a large sample of mandibles. To test the accuracy of their method, mandibles (n= 24), which are of known sex (male) and age, from the Nicea remains (13th century) were assessed for the presence or absence of mandibular ramus flexure. The results of this study indicated that the mandibular ramus flexure was diagnostic for 91.7% of the males. These results suggest that the presence of the posterior border's flexure of the mandibular ramus can be used as a singular morphological indicator in sex determination.Publication Anthropometric measurements of femur and tibia on the byzantine skeletons of nicea remains (13th century a.d.)(Moravian Museum, 2005-01-01) ARI, İLKNUR; ŞENDEMİR, ERDOĞAN; Sendemir, Erdoğan; KAFA, İLKER MUSTAFA; Kafa, İlker Mustafa; Tıp Fakültesi; Anatomi Ana Bilim Dalı; 0000-0001-8309-0934; 0000-0001-9699-4342; AAG-7125-2021; AAA-9892-2021Skeletal anthropometric measurements to reveal regional diversity between different populations or within the same one are beneficial for understanding temporary evolutionary and developmental progress relevant to our species.Our material consisted of 26 femurs (13 left, 13 right) and 60 tibias (30 left, 30 right) of male Byzantine skeletons (13th century) excavated at Nicea in Turkey, between 1981 and 1985. Twelve osteometric parameters for femurs and five for tibias were taken into account. Indices of platymeria and platycnemia were derived and compared with other studies. Non-paired t-tests were used to compare left and right. No noticeable difference was found for femurs. Anteroposterior diameter at the nutrient foramen of tibias showed minimal difference between the left and right. The platymeric index was eumeric (mean = 86). Our material indicates the existence of eurycnemia with respect to tibial flattening (mean = 74).Publication Investigation of morphological and biomechanical properties of the scapula for shoulder joint(Galenos Publishing House, 2023-09) Cini, Nilgün Tuncel; Sak, Nazan Güner; Babacan, Serdar; Arı, İlknur; ARI, İLKNUR; Sak, Nazan Güner; Tıp Fakültesi; Anatomi Ana Bilim Dalı; 0000-0002-7410-7738; ELI-9107-2022; HNN-1671-2023Objective: The glenopolar angle is a helpful criterion for recommending operative treatment. This study aims to determine the morphometric features of the scapula and provide essential information that supplies scapular biomechanics to produce a formula.Methods: The study was carried out on 34 dry scapulae in the laboratory of the Anatomy Department of the Faculty of Medicine, Bursa Uludag University. We used calipers for the linear measurements and the ImageJ program for the area and angle parameters. A total of 23 parameters were evaluated in the study. Statistical analyzes were performed using SPSS 22.0 software. Results: According to the results of the correlation analysis, the highest correlation value of (R=0.957) was found to be the distance between the superior angle (angulus superior)-top of the glenoid plane and the inferior angle (angulus inferior)-the top of the glenoid plane. To estimate the glenopolar angle, we applied linear regression analysis and developed the following formula: Glenopolar angle =115.589 - (6.401 x the distance between the coracoid process and the top of the glenoid cavity) - (0.368 x angle between the glenoid plane and the lateral edge of the scapula extending towards the endpoint of the glenoid plane) (Adjusted R2=0.667).Conclusions: Glenopolar angle can provide information about the fracture risk of the glenoid cavity and allows orthopedic surgeons to make quick decisions about the risk in the region. We believe that the study will provide a different perspective on designing different products in industrial designs for shoulder joints, especially in implantations.Publication Morphometry of the greater sciatic notch on remains of male byzantine skeletons from nicea(Soc Anatomica Espanola, 2005-12-01) Arı, İlknur; ARI, İLKNUR; Tıp Fakültesi; ELI-9107-2022It is well known that there are metric and no-nmetric variations in the expression of sexual dimorphism between racial phenotypes and populations. The creation of skeletal anthropometric measurements of different populations is useful for both comparisons with similar studies and for improving the identification of human skeletal remains. The features of the greater sciatic notch of the coxae are characteristic and are commonly used to determine sex in unknown individuals. In this study, several measurements of the greater sciatic notch, e.g. width (AB), depth (OC) and width of the posterior segment (OB) were taken and indices I and II were calculated in 26 adult male coxae of Byzantine skeletons (13th century) excavated at Nicea in Turkey. The results for the right and left greater sciatic notch were found to be AB: 46.00 mm (+/- 7.16) and 46.92 mm (+/- 5.93); OC: 25.23 mm (+/- 6.62) and 28.07 mm (+/- 4.78); OB: 20.30 mm (+/- 7.83) and 20.61 mm (+/- 5.25); Index I: 55.51 (+/- 15.83) and 61.02 (+/- 14.26); and Index II: 43.28 (+/- 11.35) and 44.67 (+/- 12.98), respectively. In conclusion, this study provides quantification of the features of the greater sciatic notch in the os coxae of late Byzantine period (13th century) skeletons that should be of value in forensic and archaeological analyses, especially when dealing with fragmentary remains.Publication Morphometric features of external opening of the carotid canal and relationship with some neighboring formations on the skull base(Lippincott Williams & Wilkins, 2020-06-01) Çini, Nilgün Tuncel; Babacan, Serdar; Arı, İlknur; BABACAN, SERDAR; ARI, İLKNUR; Çini, Nilgün Tuncer; Tıp Fakültesi; Anatomi Ana Bilim Dalı; 0000-0002-7410-7738; ABF-7082-2020; CKL-4474-2022; ELI-9107-2022The carotid canal must be taken into account during the surgical procedures since it contains the petrous segment of internal carotid artery. For this reason, we aimed to reveal the morphometric relationship of the carotid canal with related structures. The study was carried out with 11 parameters determined on a total of 52 sex unknown temporal bones belonging to the collection of Bursa Uludag University Faculty of Medicine, Anatomy Department. Measurements were taken by using mechanical sliding calipers and the findings were evaluated using the SPSS 22.0 program. Descriptive statistics of all variables were performed and correlation between the carotid canal and related structures were evaluated with the Spearman correlation analysis. Also, the correlation coefficient values were given. We developed the regression formulas to estimate the location of the carotid canal. There was a relationship between posterior and anterior point of external opening of carotid canal and mastoid process. The distance between the mastoid process-suprameatal spine and mastoid process-posterior root of zygomatic arch is highly correlated with each other.Publication Examination of facial convexity and concavity values with reference to the external acoustic pore: A retrospective study(Lippincott Williams & Wilkins, 2023-05) Çini, Nilgün Tuncel; Babacan, Serdar; Sak, Nazan Güner; Işıklar, Sefa; Arı, İlknur; Gökalp, Gökhan; IŞIKLAR, SEFA; ARI, İLKNUR; GÖKALP, GÖKHAN; Sak, Nazan Güner; Tıp Fakültesi; 0000-0002-2070-5193; HNN-1671-2023; AAK-3779-2021; ELI-9107-2022; GMO-0473-2022The human skull serves as an essential material for facial reconstruction. In particular, the petrous part of the temporal bone is vital due to its compact structure, which can resist mechanical forces. The study aims to give descriptive values to estimate the face shape and produce regression formulas through the external acoustic pore as a reference point. The study was carried out on 3-dimensional computed tomography images, a total of 83 adult images (45 females and 38 males) in the Department of Radiology of Bursa Uludag University Medical Faculty. The distances between the imaginary vertical line passing through the porion and the anthropometric points revealing the facial features were measured for the soft and hard tissue. The vertical distances between the soft and hard tissue landmarks were also measured for both sexes. Measurements were performed with the Image J program, and for the statistical analysis, SPSS 25.0 was used (P < 0.005). Linear simple regression analysis was used to produce formulas to estimate the soft tissue thickness using hard tissue. Also, discriminant function analysis was performed to determine sex in the presence of an unknown skull. The descriptive values of the variables on the axial and vertical planes and the differences between sexes are given. Also, all formulas make accurate predictions of 90% or more. The authors tried to estimate the anatomical points that roughly reveal the facial features with the regression formulas developed using anthropometric measurements. The authors think that the shape of the face, which is more specific to the individual, can be reached more clearly using mathematical models, and the authors believe that this study will set an example for future studies.
