Öğe Developmental variations and clinical importance of the fetal thyroid gland: A morphometric study(2007) Cicekcibasi A.E.; Salbacak A.; Seker M.; Ziylan T.; Tuncer I.; Buyukmumcu M.Objetives: To investigate the morphologic structures and developmental anomalies of the thyroid gland in human fetuses. Methods: This study performed in the Department of Anatomy, Meram Faculty of Medicine between February and April in 2002. Fetuses were obtained from the Gynecology Department of the Meram Faculty of Medicine, Selçuk University, and Dr. Faruk Sukan Maternity Hospital (Konya, Turkey), Sixty spontaneously aborted fetuses (30 boys and 30 girls) between the ages of 13.5th and 32.5th weeks, which had no detectable anomalies, were evaluated. The gland was dissected under the microscope. The location of the gland was determined according to the tracheal ring levels and laryngeal cartilage levels. The length, width and thickness of both lobes and isthmus of the gland were measured and then, the developmental anomalies were noted. The obtained data were statistically analyzed by Least Squares in variant analysis. Results: Although there was no significant difference regarding to the gender for all parameters except in width of the right lobe (p<0.05), difference in the length and width of lobes and the length of isthmus between trimesters was significant (p<0.05). All measured parameters were increasing with advancing gestational age. The pyramidal lobe was observed in 18.3% of the cases. Conclusion: Normal dimensions and developmental anomalies of the fetal thyroid, which was shown in this study, may provide useful information for the prenatal diagnosis and in-utero treatment of thyroid dysfunctions.Öğe An investigation of the acetabulum, the femoral head and the ligament of femoral head in human fetuses(2004) Uysal İ. İ.; Salbacak A.; Kapıcıoğlu M. İ. S.; Büyükmumcu M.; Şeker M.; Çiçekcibaşı A. E.We investigated the morphometric characteristics of the acetabulum, the ligament of the femoral head (LFH) and the femoral head, and the relationships among them in 30 spontaneously aborted human fetuses. The maximum length and width of the LFH, the transverse and vertical diameters of the femoral head and the acetabulum, the height of the femoral head and the depth of the acetabulum were measured and the existence of any relationship among them was assessed statistically. The acetabulum was circular in 58.4% of cases and oval in 41.6%. The diameter of the femoral head was less than that of the acetabulum in 91.7% of subjects. In one case the base of the acetabulum was devoid of cartilage tissue. When all of the parameters were compared according to gender and lateralization, only the length of the LFH in females on the left side was greater than that on the right side (P < 0.05). There was a high correlation between the diameters of the acetabulum and the femoral head as well as the acetabular depth and the height of the femoral head. The relation between gestational age and the measured data was significant (P < 0.05). The presented data may help to explain the effect of hip joint morphology during developmental stages on the process of some congenital hip joint diseases.Öğe Unilateral variations of vessels and nerves in the neck [Variación unilateral de vasos y nervios en el cuello](2010) Dogan N.U.; Cicekcibasi A.E.; Fazliogullari Z.; Yilmaz M.T.; Uysal I.I.; Salbacak A.Variations of vessels and nerves in the left neck side, of 65 year old male cadaver, during the routine dissections, were detected. It was observed that the linguofacial trunk originated from external carotid artery and that the ascending pharyngeal artery originated from the occipital artery. It was determined that after the laryngeopharyngeales rami originated from the superior cervical ganglion, the branch wound around the origin of the superior thyroid artery. As an additional variation, the internal jugular vein divided. The cervical ansa and the inferior belly of the omohyoid muscle passed through the parts of the vein. We think that these type of variation can entail important difficulties during radiologic and surgical procedures of the neck region. To know these anatomical variations, is important for the anatomist and surgeons.
