Öğe Anatomical structure and topographic anatomy of sciatic nerve in human fetuses(Wolters Kluwer Medknow Publications, 2016) Kabakci, A. D. Aydin; Buyukmumcu, M.; Yilmaz, M. T.; Cicekcibasi, A. E.; Akin, D.Introduction: Sciatic nerve is the longest and thickest nerve of the human body which divides into two branches in popliteal fossa. Variations of sciatic nerve can be observed during the course of the nerve. These anatomical variations contribute to some clinical manifestations such as piriformis syndrome, sciatalgia. Methods: This study was conducted on 60 aborted fetuses aged between 9 and 40 gestational weeks and with no gross anomalies. Morphometrical measurements related to the nerve and the neighboring structures were performed and also incidence of anatomical variations was determined. Results: All parametric data were seen increased with gestational age (p < 0.05). Also, no statistical differences between the parameters from right and left were found (p > 0.05). The sciatic nerve division was observed in 99 (82.5%) lower extremities in the popliteal fossa, 19 (15.83%) at a level above the popliteal fossa, and in 2 lower extremities (1.67%), high division was observed. Also, the status of sciatic nerve was assessed in regard to piriformis muscle. In 118 of the lower extremities (98.3%), sciatic nerve was observed leaving from underneath the piriformis muscle as one piece and the remaining 2 (1.67%) were observed as giving division at higher levels. In one of these lower extremities of the right side, tibial nerve branch was observed following a path under piriformis muscle and common peroneal nerve was observed passing through the piriformis nerve. Discussion: We believe that our study will provide data regarding the development of sciatic nerve in fetal period and that data will contribute to related clinical studies and applications.

Aydin; Sener, S.Background: The aim of this study was to compare the morphological differences in the mandible between patients with six age groups and to detect the correlation between these parameters on panoramic radiography (PR) and cone-beam computed tomography (CBCT). Materials and methods: A total of 121 subjects (50 males and 71 females) were included in the study and were divided into six age groups (10-19, 20-29, 30-39, 40-49, 50-59, and 60-69) on the basis of the chronological age. CBCT and PR methods were used to record the mandibular measurements for the same 121 patients. Differences between male and female mandibular morphometric measurements, between right and left side measurements, and differences in age subgroups compared by using independent samples t-test, paired samples t-test, and one-way ANOVA test, respectively. P < 0.05 value was considered statistically significant for all analysis. Results: Males mostly have higher mandibular measurement values. There were statistically significant differences between CBCT and PR measurements (p < 0.05). PR mostly showed higher values than CBCT measurements. Conclusions: Based on the fact that PRs showing significant differences from CBCT in the morphometric measurements made on mandible, it is recommended that forensic doctors and anthropologists consider this information in their age and gender prediction studies.Öğe Complete Ossification of the Superior Transverse Scapular Ligament in an Turkish Male Adult(Soc Chilena Anatomia, 2013) Buyukmumcu, M.; Seker, M.; Ozbek, O.; Akin, D.; Koc, O.; Aydin, A. D.; Salbacak, A.Scapula has three margins and angles and located posterolateral of thorax. One of the anatomical structures of scapula is suprascapular notch located medial to coracoid process base. Suprascapular notch can be seen in different shapes and depths. Suprascapular notch is surrounded by transverse scapular ligament which is a short and strong ligament. Suprascapular notch creates an osteofibrosis passage with this structure within suprascapular nerve passes. It has been reported that this osteofibrosis structure can intirely or partially ossify. All lesions of nerves occured in course as result of exposure to compression, tension and bending are called entrapment neuropathy. Like other peripheral nerves, suprascapular nerve can be exposed to compression while passing suprascapular notch. As a result of this compression suprascapular entrapment neuropathy may occur. There are direct trauma, repetitive microtrauma, neurit, progressive compressive lesions in suprascapular entrapment neuropathies etiology. A suprascapular notch taken foramen shape can be a predisposing factor to entrapment neuropathy. In the retrospective screening from Necmettin Erbakan University, Meram Medical Faculty, Department of Radiology archive, a male patient at age 68 with suprascapular notch variation has been detected. This patient's right suprascapular notch had became foramen by an osseous bridge. Diameters of foramen has been measured as 5.27 mm transverse 6.48 mm vertical. We believe having detailed knowledge of suprascapular notch is significant as a possible course of back and shoulder pain is entrapment of suprascapular nerve in suprascapular notch causing nerve paralyses, and it will give a right direction to clinicians in surgical practices.Öğe An Osteometric Study on Humerus(Soc Chilena Anatomia, 2017) Aydin Kabakci, A. D.; Buyukmumcu, M.; Yilmaz, M. T.; Cicekcibasi, A. E.; Akin, D.; Cihan, E.Humerus is the longest and thickest bone of the upper limb. As a long bone, it has two epiphysis and diaphysis. In this study, we aimed to conduct morphometric measurements belonging to human humerus. This study was conducted on 60 humerus (28 right, 32 left) in collections of Necmettin Erbakan University Meram Medicine Faculty Anatomy Laboratory. Digital calipers, osteometric board and precision scales for humerus bone measurements were used. Measurements were classified as measurements of diaphysis and proximal and distal epiphysis of humerus. Each bone weight was determined. Also nutrient foramen number and localization was determined. In this study, it was determined that mean right humerus length 30.41 +/- 1.73 mm, mean left humerus length 30.04 +/- 2.39 mm. It was identified that mean right humerus weight was 115.05 +/- 28.06 g, mean left humerus weigh twas 111.63 +/- 33.34 g. In 9 humerus (15 %), supratrochlear foramen has been observed. 6 of these were oval and 3 of them were round. Nutrient foramen has not been observed in two humerus (3.3 %). Also, medium and weak correlation was identified between many parameters. We believe that the obtained data from this study may be qualities of reference for sex determination from humerus.
