Publication Bilateral variation in the course of the internal carotid artery: Case report(Soc Anatomica Espanola, 2007-12-01) Uysal, Mükerrem; Bakırcı, Sinan; Coşkun, İhsaniye; Arı, I.; Uysal, Mükerrem; Bakırcı, Sinan; COŞKUN, İHSANİYE; Arı, I.; Uludağ Üniversitesi/Tıp Fakültesi/Anatomi Anabilim Dalı; 0000-0001-6484-7153; 0000-0003-1170-6036; GFC-4180-2022; CEQ-6552-2022; AAH-5390-2021; ELI-9107-2022The internal carotid artery arises at the bifurcation of the common carotid artery and continues upwards within the carotid sheath. It has no branches and passes straight up in the carotid sheath and beside the pharynx to the carotid canal in the base of the skull. This division of the internal carotid artery is defined as the cervical part. Variations in the course of the cervical part have been found in the different studies and have been classified as kinking, coiling and tortuosity. It is known that these variations are associated with cerebrovascular failure and transient ischaemic attack. During routine dissections of the cervical region for educational purposes, bilateral course variations with a marked kinking on the right and distinctive tortuosity on the left side were found in the internal carotid artery of a 75-year old male cadaver. The case is of interest since variations in the course of the internal carotid artery have been shown to be related to cerebrovascular failure.Publication The surface and intracranial location of asterion(Lippincott Williams & Wilkins, 2019-11-01) Babacan, Serdar; BABACAN, SERDAR; Yıldız-Yılmaz, Meriç; Kafa, İlker Mustafa; KAFA, İLKER MUSTAFA; Coşkun, İhsaniye; COŞKUN, İHSANİYE; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Anatomi Anabilim Dalı.; 0000-0002-7410-7738; 0000-0001-8309-0934; 0000-0001-6484-7153; AAG-7125-2021; ABF-7082-2020; AAH-5390-2021Background: Asterion is identified as the connection point of sutura parietomastoidea, sutura occipitomastoidea, and sutura lamb doidea. The location of asterion, which is primarily preferred as a landmark during posterolateral surgical approach for intracranial operations, shows many variables. The aim of this study was to identify the surface location of the asterion and determine the distances between intracranial anatomical structures and asterion.Methods: At this present study, 11 hemicraniums (22 asterion points), situated at the laboratory of Department of Anatomy, Faculty of Medicine, Bursa Uludag University, were used. The asterion points which the sesamoid bone located were classified as type I and the ones which sesamoid bone did not locate were classified as type II. According to the proximity of asterion with sinus transversus, 3 groups were classified. About 19 parameters were measured related to asterion. The obtained data were analyzed in SPSS 22.Results: As a result of findings, while sesamoid bone was seen at 7 asterion points (type I), at 15 points sesamoid bone was not detected (type II) (respectively, 31.81%, 68.19%). It was identified that 15 asterion points were at the surface, 5 ones were average 3.42 +/- 2.52 nun over, 2 ones average 3.21 +/- 2.26 nun below of the projection of sinus transversus. Statistically significance was not seen between the measurements taken from left and right sides.Discussion and Conclusion: Asterion is an important landmark for the retrosigmoid approaches. The surface and intracranial location of the asterion and proximity with dural sinuses are important for surgeons not to cause fatal subdural hematomas during the approaches using "Burr Hole" technic in neurochirurgie operations.Publication A comparison of the relationship between the golden ratio and anatomical characteristics of the supraorbital foramen in bare skulls belonging to the byzantine era and modern era(Soc Chilena Anatomia, 2016-06-01) Bakırcı, S.; Kafa, İlker Mustafa; Coşkun, İhsaniye; Büyükuysal, M. C.; Barut, C.; KAFA, İLKER MUSTAFA; COŞKUN, İHSANİYE; Uludağ Üniversitesi/Tıp Fakültesi/Anatomi Anabilim Dalı; 0000-0001-8309-0934; AAH-5390-2021; AAG-7125-2021The aim of the present study is to determine the frequency of the occurrence of supraorbital foramen/notch (SOF/N) in the skulls of the people who lived in the modern era and the late Byzantine era, to determine the symmetry and the asymmetry between the two halves of the skulls by measuring the linear distance to various landmarks, to check the consistency between the location of the SOF/N and the golden ratio by calculating the ratio between linear distances and to evaluate the differences between the skulls from both historical periods. In the study, the frequency of the occurrence of the supraorbital notch in the skulls from the Byzantine era was found to be 26.60 % on the right and 13.30 % on the left while it was 14.30 % on the right and 9.52 % on the left in the skulls belonging to modern humans. In the skulls belonging to the Byzantine era, the average distance between SOF/N and the sagittal axis passing along the lateral orbital wall was found to be 34.81 +/- 2.51 mm and 32.99 +/- 2.81 mm respectively on the right and the left while it was 33.14 +/- 2.19 mm and 33.39 +/- 2.06 mm in the skulls belonging to modern era. The average distance between the SOF/N and the sagittal plane passing along the midline of the skull was found to be 24.55 +/- 2.79 mm and 21.57 +/- 2.44 mm on the right and the left respectively in the skulls belonging to the Byzantine era while it was 0.04 +/- 3.30 mm and 20.96 +/- 2.37 mm in the skulls belonging to the modern era. The average distance between the SOF/N and sagittal plane passing along the medial orbital wall was found to be 23.78 +/- 3.60 mm and 23.81 +/- 3.20 mm on the right and the left respectively in the skulls belonging to the Byzantine era while it was found to be 22.23 +/- 3.29 mm and 23.97 +/- 1.93 mm in the skulls belonging to the modern era. The average value of the distance between the sagittal planes passing along the lateral and medial sides of the orbit and the ratios between the distance from SOF/N to the sagittal plane passing along the lateral side of the orbit was found to be 1.47 +/- 0.21 mm and 1.60 +/- 0.08 mm respectively in the skulls belonging to the Byzantine era and the modern era. No significant difference was found between this ratio and the golden ratio; the average value of the ratios between the distance from the SOF/N to the sagittal plane passing along the midline of the skull and the distance from the SOF/N to the sagittal plane passing along the lateral side of the orbit was found to be 0.98 +/- 0.26 mm and 1.04 +/- 0.36 mm respectively in the skulls belonging to the Byzantine era and the modern era. A significant difference was found between this ratio and the golden ratio for both historical periods (modern society and late Byzantine period) (p < 0.005). The comparison of the relevant anatomic characteristics of the SOF/N is very important for anthropologists while a broad knowledge on proportional calculations regarding morphometric values and the location are important for reconstructive surgeons and the experts in forensics and pain control.
