Publication Usability of dental pulp visibility and tooth coronal index in digital panoramic radiography in age estimation in the forensic medicine (vol 134, pg 381, 2020)(Springer, 2020-05-01) Gök, Ertuğrul; Fedakar, Recep; Mustafa Kafa, İlker; FEDAKAR, RECEP; KAFA, İLKER MUSTAFA; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Adli Tıp Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Anatomi Anabilim Dalı.; 0000-0001-8309-0934; AAH-6287-2021; AAG-7125-2021Publication A neurosurgical assessment of the blood supply in the optochiasmatic system: A cadaveric-anatomic study(Springer, 2021-01-05) Baykal, Duygu; Yılmazlar, Selçuk; Fedakar, Recep; Baykal, Duygu; YILMAZLAR, SELÇUK; FEDAKAR, RECEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Beyin Cerrahisi Anabilim Dalı; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Adli Tıp Anabilim Dalı; 0000-0003-3633-7919; AAH-5070-2021; AAH-6287-2021; GMD-4113-2022The chiasmal and subchiasmal surfaces are of critical importance in connection with the performance of surgical procedures owing to the critical blood supply to these areas. Recently, the perforating arteries providing the blood to the optic nerves and chiasm have gained attention as they significantly affect the morbidity from surgical approaches. Intraoperative preservation of these perforating arteries is considered critical to prevent further visual loss. Thirty autopsy specimens, including the optic apparatus, were examined for their perforating arteries feeding the optic chiasm and optic nerves. The optic nerves and chiasmal surfaces were divided into four zones based on the presence and numbers of perforating arteries as anterior superior-posterior superior surfaces and anterior inferior-posterior inferior surfaces. The superior surface of the optic chiasm was supplied by the A1 segments of the bilateral anterior cerebral arteries and by the perforating arteries originating from the anterior communicating artery. On the other hand, the inferior surface of the optic chiasm was fed by the bilateral posterior communicating arteries and by the supraclinoidal segments of the bilateral carotid arteries. We demonstrated the anatomical involvement of a large number of nourishing arteries in feeding the optic apparatus related to the perforating arteries by classifying them into zones based on the surgical approaches, which has been rarely reported in the literature.Publication The anatomic variations and surgical windows among optic chiasm/nerves and carotid arteries in the sellar region play a role in choosing the best surgical approaches: A Cadaveric study(Elsevier Espana, 2020-05-01) Baykal, Duygu; Yılmazlar, Selçuk; Fedakar, Recep; Baykal, Duygu; YILMAZLAR, SELÇUK; FEDAKAR, RECEP; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Beyin Cerrahi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Adli Tıp Anabilim Dalı.; 0000-0001-9833-9392; 0000-0003-3633-7919; AAH-5070-2021; AAH-6287-2021; GMD-4113-2022Objective: Understanding the relationship between the carotid artery, optic nerve and the anterior clinoid process is the basis of surgical approaches performed in the subchiasmal region. The location of the optic chiasm, the length of the optic nerves, and the distance and angle between the optic nerves determine the route of surgical approaches. We have determined the types of optic chiasm to study the relationship between vascular and neural structures in this region.Materials and methods: Thirty autopsy specimens were investigated at the Bursa Forensic Medicine Institute for optic chiasm types and the relationship between the neural and vascular anatomical structures of the sellar-parasellar and subchiasmal region was examined between June 2016 and November 2016.Results: In this study, 4 prefix types (13%), 6 postfix types (20%), and 20 central types (67%) of chiasm were defined. Furthermore, we measured this angle between two optic nerves, which indirectly shows the location of chiasm according to the diaphragma sellae, and then detected the mean value of this angle as 87.1 +/- 11.6 degrees. The "limit" value to designate a chiasm as prefix was measured in the current study as >= 101.1 degrees. T.he angle between optic nerves ranged from a mean value of 69.9 +/- 3.7 degrees in 6 cases with postfix chiasm, to a mean value of 104.0 +/- 2.1 degrees in 4 cases with prefix chiasm and a mean value of 88.8 +/- 6.7 degrees in 20 cases with central chiasm.Conclusion: In this study, we showed that the relationship among optic chiasma types, optic nerves and bony and vascular structures around the sellar area was effective at determining the surgical approach to this region.

Two accidental hanging cases were autopsied at The Council of Forensic Medicine, Bursa Group Chairmanship, Morgue Department. The inquest papers written by police were examined and the scenes and autopsy findings are presented. The first case was a four year old girl and the second case was a five year old boy. Their manners of death were determined as an accident. The first accident occurred out of home, but the second accidental hanging occurred at home. It was seen that childhood deaths due to hanging are preventable. Detailed medico-legal investigation in order to elucidate the manner of death is required in similar cases.
