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 Effects of Serum Vitamin D Levels on Snoring in Patients Who Have Undergone Septorhinoplasty(Wolters Kluwer Medknow Publications, 2018) Ince, Bilsev; Sakarya, Mehmet Emin; Dadaci, MehmetBackground/Aim: The aim of the study was to determine the clinical and radiological effects of septorhinoplasty and the change in serum Vitamin D levels on snoring. Patients and Methods: Sixty patients who attended with complaints of snoring, difficulty in breathing through the nose, and nasal deformity were included in this prospective study. Patients who only underwent septorhinoplasty were defined as Group 1, patients who underwent septorhinoplasty and were administered Vitamin D were defined as Group 2, and patients who were administered Vitamin D without undergoing septorhinoplasty were defined as Group 3. Results: In Groups 2 and 3, changes in the anteroposterior diameter of the air column, column of the airspace, and thickness of the soft palate and the uvula were statistically significant. Snoring decreased significantly at every postoperative follow-up in all three groups. This decrease was significantly higher in Group 2 than in Groups 1 and 3. Conclusions: We determined that one reason for snoring may be Vitamin D deficiency. Replacement of Vitamin D with removal of the upper respiratory tract problems may prevent snoring in patients with snoring and Vitamin D deficiency.Öğe CT Findings of Mycobacterium Avium Intracellulare Infections in the Lung(Modestum Ltd, 2014) Keskin, Suat; Sakarya, Mehmet Emin; Keskin, ZeynepMycobacterium avium intracellulare (MAI) is the most common pulmonary pathogen in the population with acquired immunodeficiency syndrome (AIDS).

Sexual dimorphism between the male and female brain starts in the fetal period under the influence of genetic and hormonal factors. In addition, the newborn brain begins to change in terms of both brain volume and morphology. In the present study, we evaluated gender-related changes in brain volume in children 1-5 years old. Magnetic resonance images of 30 healthy children aged 1-5 years old (15 male, 15 female) were obtained from the Department of Radiology, Meram School of Medicine, University of Necmettin Erbakan. The Cavalieri method and point-counting were used to determine the brain hemisphere volumes from these images. The mean volumes of the right cerebrum in female and male children were 423.26 +/- 110.62 cm(3) and 456.43 +/- 161.39 cm(3), respectively, and those of the left cerebrum were 416.41 +/- 103.51 cm(3) and 460.42 +/- 154.99 cm(3), respectively. There were no significant differences in cerebrum hemisphere volumes between male and female children 1-5 years old (P > 0.05).Öğe The Evaluation of Morphometry of Nasal Bone and Pyriform Aperture Using Multidetector Computed Tomography(Lippincott Williams & Wilkins, 2014) Yuzbasioglu, Neslihan; Yilmaz, Mehmet Tugrul; Cicekcibasi, Aynur Emine; Seker, Muzaffer; Sakarya, Mehmet EminIntroduction: The aim of this study was to measure nasal bone (NB) and pyriform aperture (PA), morphometrically. Besides, the different types of NB and PA were classified and determined the sexual differences. Materials and Methods: Our study was performed on 120 (60 women, 60 men) multidetector computed tomography images obtained from patients who underwent radiologic examination in the Department of Radiology of Meram Faculty of Medicine, Necmettin Erbakan University. The right, left, and median heights of NB; the superior and inferior widths of NB; the width of PA; and the distance between rhinion and anterior nasal spine (as the height of PA) were measured. Frontonasal and internasal angles were also determined. All data were analyzed statistically using Student's t-test. Results: The other data of men were higher than of women except for the superior and inferior widths of NB and the frontonasal angle. We also determined the ratio of the height of PA to the height of NB on median plane and the ratio of the height of PA to the width of PA. They were found less than 2.0 in 64.2% and 100% of the cases, respectively. The NB and PA were classified into 8 and 7 different types, respectively. Conclusions: The knowledge of the morphometric data and different types of the NB and PA is essential for sex determination, all surgical procedures related to this area, and nasal reconstructions.Öğe The Evaluation of Morphometry of the Mastoid Process Using Multidetector Computed Tomography in a Living Population(Lippincott Williams & Wilkins, 2015) Yilmaz, Mehmet Tugrul; Yuzbasioglu, Neslihan; Cicekcibasi, Aynur Emine; Seker, Muzaffer; Sakarya, Mehmet EminThe aim of this study was to examine the relationships of the bony landmarks on the lateral surface of the mastoid process (MP). It was also the target of this study to reveal the importance of sexual dimorphism in terms of the mastoid triangle. Our study was performed on 140 (70 women, 70 men) multidetector computed tomography images obtained from patients who underwent radiologic examination at the Department of Radiology of Meram Medical Faculty, Necmettin Erbakan University. The height of the MP was measured using 2 different ways. The distance between the mastoid apex and the midpoint of the distance of the porion and the mastoid notch was measured (mastoid height 1). Then, the distance between the Frankfurt horizontal plane and the mastoid apex was measured (mastoid height 2). The distances between porion-mastoid notch, porion-mastoid apex, porion-asterion, asterion-mastoid apex, articular tubercle-asterion, articular tubercle-mastoid apex, as well as the right and the left MP were also measured. Finally, the angles between porion-mastoid apex-asterion, mastoid apex-asterion-porion, and asterion-porion-mastoid apex were measured. All data were analyzed statistically using the Student's t-test. According to the results of the measurements, all right and left parameters of the men were higher than the women's right and left sides except for the angle between asterion-porion-mastoid apex. In addition, all right and left parameters were almost the same in both sexes. Having the knowledge of measurements of the distances between the major landmarks of the temporal bone is essential to avoid possible complications during facial, mastoid, and especially sigmoid sinus surgeries.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 Osteophyte Arising From The Cricoid Cartilage Causing Dysphagia(Modestum Ltd, 2014) Batur, Abdussamet; Sakarya, Mehmet Emin; Uslu, AbdulazizAlthough cervical degenerative changes is a common disorder, dysphagia induced by osteophyte formation is uncommon. We present a case of 54-year-old patient suffering dysphagia secondary to cricoidal osteophyte. Phsical examination showed no abnormality. A barium esophagography revealed anterior compression of the esophagus at the level of cricoid cartilage. A computed tomography (CT) showed a small spur originating from the cricoid. Magnetic resonance imaging (MRI) demonstrated the osteophyte-induced edema and allowed the differential diagnosis with the other causes of dysphagia. In this report, radiological features of cricoidal osteophyte is presented.Öğe Osteophyte Arising From The Cricoid Cartilage Causing Dysphagia(Modestum Ltd, 2014) Batur, Abdussamet; Sakarya, Mehmet Emin; Uslu, AbdulazizAlthough cervical degenerative changes is a common disorder, dysphagia induced by osteophyte formation is uncommon.

Most cases of PHPV are sporadic and unilateral. We report a case of PHPV in a 5-year-old male who presented with complaint of decreasing eye size. Grey-scale ultrasonography (US) evaluation revealed an hypoechogenic band in the posterior segment of the left globe extending from the posterior surface of the lens capsule to the optic disc. Also magnetic resonance imaging (MRI) findings suggested the diagnosis of persistent hyperplastic primary vitreous.Öğe Where is the apex of the sacral hiatus for caudal epidural block in the pediatric population? A radio-anatomic study(Springer Japan Kk, 2014) Cicekcibasi, Aynur Emine; Borazan, Hale; Arican, Sule; Yilmaz, Mehmet Tugrul; Sakarya, Mehmet EminCaudal epidural block (CEB), administered through the sacral hiatus, is a regional anesthetic technique commonly used in children. To facilitate and optimize pediatric CEB, morphometric data that may be important for the sacral hiatus have been obtained using multidetector computed tomography (MDCT). This study is the first radio-anatomic study designed to address this topic in children. Images of 79 children (39 girls and 40 boys between 1 and 9 years old) were divided into three groups according to age [group I (ages 1-3), group II (ages 4-6), and group III (ages 7-9)] and were retrospectively examined. Data were gathered via 3D volume-rendered images. Measurements included the height and width of the sacral hiatus, S2-S4 (sacral vertebra) distance, the distances between the poles of the unfused spinous process of each sacral vertebra, and the dimensions of an imaginary triangle formed between the right and left posterior superior iliac spines (PSIS) and the apex of the sacral hiatus. The most frequently fused spinous process was at S2 level. The mean S2-S4 distance was 1.36 cm for group I, 1.78 cm for group II, and 2.17 cm for group III. There was not the imaginary equilateral triangle used in the method of finding the sacral hiatus for CEB, and the apex of this triangle did not occur at the standard level (S4) in most of the children. It was observed that the apex deriving from the most distal fused spinous process was at the level of S2 in one of two children. Dural puncture is inevitable for CEB applied at the S2 level. Consequently, CEB should be applied below this level (range, 1.36-2.17 cm) from the midpoint of the interspinous distance between the PSIS (at the same level with S2) in children aged 1-9 years.
