Öğe Arterya Karotis İnternanın Seyir Varyasyonları(2014) Acar, Musa; Zararsız, İsmail; Ulusoy, Mahinur; Sakarya, Mehmet Emin; Acar, Serpil; Şimşek, TubaAmaç: Arterya karotis interna (AKİ) tiroid kıkırdağın üst kenarı hizasında, arterya karotis communisin uç dalı olarak başlar. Boyun diseksiyonu sırasında, bölgeye ait anatomik detayların iyi bilinmesi, cerrahlara, bu komplikasyonlardan kaçınmada, önemli ölçüde yardımcı olacaktır. Yapmış olduğumuz çalışmada Türk toplumuna ait AKİnin seyir varyasyonlarını ve görülme sıklıklarını tespit etme amaçlandı. Gereç ve Yöntem: Çalışma multidedektör komputerize tomografi anjiografi (MDCTA) görüntüleri üzerinde gerçekleştirildi. Çalışmaya yaşları 31 ile 86 arasında yer alan 94 hasta (32 kadın-62 erkek) (94 sağ-94 sol, toplam 188 olgu) dahil edildi. Bulgular: Çalışmamızda AKİnin servikal bölgede 4 farklı seyir tipi gösterdiği tespit edildi. Tartışma: Çalışmamızda ortaya koyduğumuz seyir varyasyonlarının cerrahlar ve radyologlara teşhis ve tedavi açısından faydalı olacağını düşünmekteyiz.Öğe An assessment of the face on Turkish and African students.(Allied Acad, 2017) Acar, Musa; Alkan, Senay Burcin; Ulusoy, Mahinur; Akkubak, YaseminIntroduction: Calculating the values about the human body dimensions and evaluating them is possible by physical anthropometry. Those values are affected by the factors such as ecological, biological, geographic, racial, gender and age. Method: This study has been carried out on 40 (20 male, 20 female) Turkish and 40 (20 male, 20 female) African students whose ages differed between 18-25 studying in the University of Mevlana and University of Necmettin Erbakan. In the research, the individuals who had been identified with a morphological deformation had a major trauma and plastical or reconstructive surgeries are excluded. The parameters for measurement have been determined as; eye-fissure width (right), eye-fissure width (left), intercanthal distance, outercanthal distance, nose width, nose height, mouth width. Results: Morphometric parameters belonging to both race males and female ears were compared between genders. Right and left tragus-helix and tragus-antihelix distance of Turkish male individuals were founded significantly lower than African male individuals, right and left lobular width and lobular height were founded significantly higher than African male individuals (p<0.05). Left and right ear length of Turkish female individuals, lobular width and left lobular width were founded significantly higher than African Female individuals (p<0.05). Conclusion: Consequently, the values we obtained are important for establishing a referential gap between the individuals of Turkish and African races. Also we are of the opinion that those values will be useful to the anatomists in the anatomical education and to the aesthetic surgeons and dentists.Öğe The effect of zinc deficiency and zinc supplementation on element levels in the bone tissue of ovariectomized rats: Histopathologic changes(Taylor & Francis Ltd, 2014) Baltaci, Abdulkerim Kasim; Sunar, Fusun; Mogulkoc, Rasim; Acar, Musa; Toy, HaticeObjective: Study aimed to determine the effects of zinc supplementation/deficiency on the histological structure and elements levels in bone tissue in ovariectomized rats. Methods: The study included 40 Sprague-Dawley type adult female rats, divided as follows: Control, ovariectomized, ovariectomized + zinc supplemented, ovariectomized + zinc deficient groups. At the end of the study bone tissues (femur) were collected to determine the levels of calcium, phosphorus, magnesium, zinc, iron, aluminium, chrome, lithium, lead, nickel, and manganese. The bone tissue was examined for histopathology. Results: Ovariectomy leaded to significant decrease in magnesium. Zinc supplementation to ovariectomized rats restored the reduced calcium, phosphorus, zinc. However, zinc deficiency in ovariectomized rats further reduced calcium, phosphorus, zinc, and manganese levels. Zinc deficiency in ovariectomized significantly increased Al, Cr, Li, Pb, and Ni levels. Tissue integrity was impaired due to ovariectomy and zinc deficiency. Conclusion: Ovariectomy and zinc deficiency leads significant decreases elements of the bone.Öğe Morphometric analysis of cervical vertebrae with multidetector computerized tomography(2019) Alkan, Şenay Burçin; Acar, Musa; Tolu, İsmet; Seçkin, Erdi; Soyal, Rukiye; Saricat, Seher; Yıldız, RabiaAim: We aimed to present some morphometric values of the cervical vertebra in our study. Materials and Methods: The study was performed on 100 individuals (50 females-50 males) aged between 20 and 80 years with multidetector computed tomography and cervical vertebrae. Parameters are measured and recorded in our work; sagittal diameter of foramen vertebra, transverse diameter of foramen vertebra, sagittal diameter of corpus vertebra, transverse diameter of corpusvertebra and corpus vertebra height. Findings: We investigated whether there was a statistically significant difference between men and women. Sagittal diameter ofcorpus vertebra and transverse diameter of corpus vertebra values were significantly higher in all cervical vertebrae than in females (p0.05). Corpus vertebrae height values were significantly higher (p0.05) in men except C2 vertebrae. Conclusion: As a result, the averages we obtained are important in terms of creating reference values in Turkish society. We think that these values will help radiologists for diagnosis and surgeons for surgical interventions.Öğe The Morphometrical Analysis of the External Carotid Artery and its Branches with Multidetector Computerized Tomography Angiography Technique(Soc Chilena Anatomia, 2013) Acar, Musa; Salbacak, Ahmet; Sakarya, Mehmet Emin; Zararsiz, Ismail; Ulusoy, MahinurThe external carotid artery (ECA) is the main artery of the head and the neck region. Carotid bifurcation (CB), which is one of the place where the atherosclerotic plaques are most commonly seen. The surgical procedure of these plaques which causes cerebral vascular accident (CVA) is carotid endarterectomy. In this surgical procedure, the knowledge of the anatomical courses and variations of the carotid artery increased the surgery performance. In our study, we aimed to introduce the course, the location and the variation of the ECA's and their branches. This study is carried out on multidetector computerized tomography angiography of the ECA's of 50 men and 50 women, totally 200 ECA's (100 right, 100 left). The measurement of the inner diameter of the common carotid artery (CCA) and the ECA was evaluated. The location of the CB was determined and its vertical distance to the gonion measured. We found that the superior thyroid artery (STA) originated from the CCA, the CB and the ECA. The vertical distances between the CB and the STA, lingual (LA), facial (FA) occipital (OA) were measured. The ECA and its branches were recorded. We believe that the assessment of the ECA morphometrically may comprise control groups of diseases related to the vessel diameter and this data may be used as reference in clinic and surgery. Knowing the anatomical details and variations is vital to prevent unpredictable complications in surgery.Öğe Sakrum’un multidedektör bilgisayarlı tomografi yöntemi ile morfometrik analizi(2018) Acar, Musa; Alkan, Şenay Burçin; Durmaz, Mehmet Sedat; Seçkin, Erdi; Öztemel, Kübra; Sezgin, Zeynep; Akbaba, AleynaAmaç: Antropometrik çalışmalar kimliklendirmenin cinsiyet tespiti aşamasında önemli bilgiler sunmaktadır. Multidedektör bilgisayarlı tomografi (MDBT) yöntemi vücut oluşumlarının hızlı ve yüksek çözünürlük ile ince kesitlerinin incelenmesini sağlar. Bu çalışmada Türk toplumuna ait her iki farklı cinsiyette referans aralıklar oluşturulmasına katkıda bulunmak amaçlandı. Gereç ve Yöntem: Çalışma MDBT ile sakrumları görüntülenen ve yaşları 20 ile 80 arasında değişen 100 birey (50 kadın-50 erkek) üzerinde yapıldı. Çalışmamızda ölçülerek kayıt altına alınan parametreler; sakrum genişliği, korpus vertebra genişliği, korpus vertebra çapı, kornular arası mesafe, sakral hiatus uzunluğu, sakral kanal uzunluğudur. Bulgular: Sakral vertebra’ya ait korpus genişlikleri erkeklerde kadınlardan anlamlı (p˂0.05) derecede yüksek tespit edildi. Benzer şekilde sakral hiatus uzunluğu erkeklerde anlamlı (p˂0.05) derecede daha yüksekti. Sonuç: Sonuç olarak çalışmamızda elde ettiğimiz ortalamaların genelde literatür bilgileri ile örtüştüğünü gördük. Bazı farklılıkların yaş, cinsiyet ve ırk gibi faktörlere bağlı olduğunu düşünmekteyiz. Elde ettiğimiz bu verilerin radyoloji, anatomi ve adli tıp gibi alanlarda bilim adamları ve klinisyenlere faydalı olacağı kanaatindeyiz.
