Publication An association between femoral trochlear morphology and non-contact anterior cruciate ligament total rupture: A retrospective MRI study(Springer, 2021-01-06) Işıklar, Sefa; Özdemir, Senem Turan; Gökalp, Gökhan; IŞIKLAR, SEFA; Özdemir, Senem Turan; GÖKALP, GÖKHAN; Bursa Uludağ Üniversitesi/Sağlık Meslek Yüksekokulu/Tıbbi Görüntüleme Teknikleri Programı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Anatomi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; 0000-0002-2070-5193; AAI-2336-2021; AAK-3779-2021; FPU-9468-2022Introduction The present study aims to investigate the association of the femoral trochlear morphology with the risk of ACL injury and whether this can be considered an additional risk factor in this clinical table.Materials and methods This is a retrospective case-control study with 93 patients, 41 patients with ACL total rupture (ACL-TR), and 52 patients without ACL injury who underwent knee magnetic resonance imaging (MRI) between January 2013 and January 2016. The femoral trochlear morphology was evaluated at the proximal and distal levels from the axial knee MRI. The morphological features of the trochlea using sulcus angle, sulcus depth, condylar heights, trochlear sulcus height, percentage of condyles and trochlear sulcus height to transepicondylar width, and lateral and medial trochlear inclination were evaluated. The notch width index was measured on the coronal MR images for notch stenos.Results ACL-TR group had a significantly higher sulcus angle (p = 0.00-0.001) and lower sulcus depth (p = 0.00-0.002) than the control group at both levels. Femoral trochlea had morphometric differences between genders. NWI was lower in the ACL-TR group than the control group (control 0.273; ACL-TR 0.247), and there was a statistically significant difference (p = 0.00).Conclusion This study was shown that the difference in morphology between the trochlear sulcus of patients with normal and ACL injuries should be taken into account in order to increase awareness of ACL injuries. We observed that mild trochlear dysplasia may cause intercondylar notch stenosis rather than changing the localization of the patella. Studies are needed regarding the effect of trochlear dysplasia on ACL.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; Bursa Uludağ Üniversitesi/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.Publication Redesign of missing mandible by determining age group and gender from morphometric features of skull for facial reconstruction (approximation)(Springer Heidelberg, 2021-05-01) Babacan, Serdar; Işıklar, Sefa; Kafa, İlker Mustafa; Gökalp, Gökhan; GÖKALP, GÖKHAN; KAFA, İLKER MUSTAFA; IŞIKLAR, SEFA; Bursa Uludağ Üniversitesi/Tıp Fakültesi; Bursa Uludağ Üniversitesi/ Sağlık Hizmetleri MYO; 0000-0002-7410-7738; 0000-0002-2070-5193; 0000-0001-8309-0934; AAK-3779-2021; AAG-7125-2021; GMO-0473-2022The identification of an unknown person by facial reconstruction, gender, and age determination is one of the duties of the forensic sciences. In some cases, the skull and mandible cannot be obtained together. In this case, facial reconstruction of the skull without a mandible becomes a serious problem. The aim of our study was to design the mandible suitable for the anatomic structure of the skull by first determining the age group and gender of the skull for skulls without mandible. Our study was carried out on 3D-CT images provided in Bursa Uludag University Radiology Department. Individuals were divided into five age groups considering tooth and bone development. Our study was conducted on 282 3D-BT images. Twenty-three variables on the mandible and 54 variables on the skull were examined. SPSS 20.0 was performed for the developing the regression formulas, discriminant function analysis, and descriptive and comparative statistics. Comparative and descriptive statistical findings between sexes and age groups are presented in tables. Discriminant function analyzes were performed for age group and gender determination. Regression formulas were developed for the redesign of the missing mandible suitable for the skull anatomy. We believe that our thesis will be useful for forensic scientists and anthropologists with the regression formulas that will design the mandible suitable for the anatomy of the skulls without the mandible and age group determination by discriminant analysis method with morphometric data.
