    Modified Composite-Flap Facelift Combined With Finger-Assisted Malar Elevation (FAME): A Cadaver Study
    (OXFORD UNIV PRESS INC, 2018-01-01) Cakmak, Ozcan; Ozucer, Berke; Aktekin, Mustafa; Ozkurt, Fazil Emre; Al-Salman, Rami; Emre, Ismet Emrah
    Background: Inadequate release of retaining ligaments during facelift surgery may lead to an unnatural appearance. However, most facelift surgeons are hesitant in transecting these ligaments to avoid possible injury to facial subbranches. Objectives: In the authors' surgical practice for modified composite flap rhytidectomy, the authors employed the finger-assisted malar elevation (FAME) technique in order to enable safe release of the zygomatic cutaneous ligaments through the prezygomatic space under direct vision. The aim was to evaluate the anatomical basis and safety measures of this technique through a cadaveric dissection study. Methods: Modified composite-flap facelift with the FAME technique was carried out in 22 fresh cadaver hemi-faces. All facial nerve subbranches were dissected thoroughly to assess for any evidence of injury during facelift, and to evaluate the safety of the operation. The relations among the facial nerve, zygomatic cutaneous and masseteric ligaments, orbicularis oculi muscle, and malar fat pad were investigated. Results: Finger dissection of the prezygomatic space allows safe release of the zygomatic cutaneous ligaments as well as adequate entry to a proper surgical plane above the zygomatici muscles under direct vision, while leaving the malar fat pad and overlying structures attached to the skin without the need of a transblepharoplasty approach. Conclusions: This study by the authors shows that a modified composite-flap facelift with FAME technique is a safe procedure that allows adequate and effective repositioning of an en-bloc composite flap that produces balanced and harmonious rejuvenation of the midface and lower face without the need of a separate midface lift.

    Evaluation of the origin and branching patterns of the iliolumbar artery and its implications on pelvic and vertebral surgery
    (SAUDI MED J, 2016-01-01) Koc, Turan; Gilan, Ismail Y.; Aktekin, Mustafa; Kurtoglu, Zeliha; Dagtekin, Ahmet; Aytac, Gunes; Cosgun, Erdal
    Objectives: To evaluate the origin, distribution pattern, branches, and neighboring structures of the iliolumbar artery (ILA) concerning the anterolateral surgical approaches to the spine. Methods: This study was performed in the Anatomy Department of Medical School, Mersin University, Mersin, Turkey between 2014 and 2015. Pelvises of 11 male formalin-fixed human cadavers were dissected by anterior and posterior approaches under surgical microscope. The origins, distribution patterns, calibers, and distances to certain structures were measured. Results: The ILA was found as a single trunk on 17 sides arising either from the IIA (12 sides, 70.6\%) or the PT (5 sides, 29.4\%). The average caliber of those originated from the posterior trunk was significantly larger (p=0.010). The ILA started as a single trunk in 17 sides, while its lumbar and iliac branches separately originating from different arteries in 4 sides. The close relation of the posterior rami of both the lumbar and iliac branches with transverse process and spinal nerve were noted. Conclusion: Findings suggest that the ILA and its branches may have different and significant patterns, which may be crucial to consider during certain surgical procedures, such as far lateral disc herniation and posterior pelvic fixations.

    The Comparison of the Right and Left Sigmoid Sinus Cross-Sectional Areas in Fetal Period and the Factors Affecting the Venous Dominance
    (AVES, 2019-01-01) Ozalp, Hakan; Aktekin, Mustafa; Hamzaoglu, Vural; Vayisoglu, Yusuf; Karatas, Mehmet Ali; Karsiyaka, Dilan; Uzmansel, Deniz; Arpaci, Rabia Bozdogan; Cayan, Filiz; Eti, Can Mehmet; Kanik, Arzu; Baskan, Fuat Cem; Aladag, Zeynep Cansu; Ertas, Elif; Dagtekin, Ahmet; Avci, Emel; Bagdatoglu, Celal; Talas, Derya Umit
    OBJECTIVES: Skull base is an important and a challenging area for surgeons. Success in skull base surgery depends on various factors such as pre-operative evaluation, appropriate surgical technique, anesthesia duration, intraoperative neuromonitorization and wound care. MATERIALS and METHODS: This study was performed in the Anatomy dissection laboratory of M.U. Medical Faculty (Ethical committee approval number 2010-103). Twelve fetuses between 17-33 gestational weeks fixed with formaldehyde were enrolled to the study. RESULTS:This study was planned to investigate the cross sectional areas of the sigmoid sinus in three levels to compare the right-left sides and the probable relationship among the levels in fetuses to further delineate the developmental factors on jugular foramen asymmetry. The cross-sectional measurements of sigmoid sinus lumen were done on 3 levels which are described as A1 level

    Morphological Features of the Popliteus Tendon, Popliteofibular and Lateral (Fibular) Collateral Ligaments
    (SOC CHILENA ANATOMIA, 2017-01-01) Kurtoglu, Zeliha; Elvan, Ozlem; Aktekin, Mustafa; Colak, Mehmet
    To reveal the detailed morphological features of the fibular collateral (fibular) ligament, popliteus tendon, popliteofibular ligament and the synovial components regarding to achieve data for surgical and biomechanical utilization. Knees of 10 formalin-fixed male cadavers were dissected bilaterally. Bursae around the lateral collateral ligament and the relation of popliteus tendon with lateral collateral ligament at the femoral attachment site were noted. The positional relation between both ends of popliteofibular ligament was evaluated statistically. The PT exceeded the anterior margin of lateral collateral ligament in 11 sides, the posterior margin of lateral collateral ligament in 3 sides and exceeded both the anterior and posterior margins of lateral collateral ligament in 5 sides. The shape of lateral collateral ligament was narrower at the lower part than the upper in 14 sides. The width of lower part of lateral collateral ligament was found narrower in the cases with sheath-like bursa (vagina synovialis). The relation between both ends of popliteofibular ligament was as followed: the more anteriorly the fibular head attachment was located, the more anteriorly popliteofibular ligament was attached to the popliteus tendon. To resolve the posterolateral corner of the knee with regard to surgical anatomy and biomechanics, individual and concerted morphometric characteristics of lateral collateral ligament, popliteus tendon and PF should be evaluated together with accompanied synovial structures.

    Axillary nerve course and position in the fetal period. An anatomic dissection study for surgical practice
    (RIYADH ARMED FORCES HOSPITAL, 2015-01-01) Uluer, Tugba; Aktekin, Mustafa; Kurtoglu, Zeliha; Buluklu, Semih; Karstyaka, Dilan; Can, Erdem
    Objectives: To examine the fetal axillary nerve to reveal and compare its morphometric features within the second and third trimester. Methods: This study was conducted at the Anatomy Department, School of Medicine, Mersin University, Mersin, Turkey. Thirty-five fetal shoulders were studied to provide anatomic data and to describe its position with regard to certain landmarks around the shoulder. Results: The shortest distance between the axillary nerve and the glenoid labrum was found 2.27 mm and 2.89 mm in the second and third trimester fetuses, respectively. The shortest distances between the anterior and posterior acromial tips and the axillary nerve were also measured and were used with arm length measurements to define the anterior and posterior indexes. Conclusion: The indexes show that the distance between the wdllary nerve and the anterior/posterior acromial tips are approximately one-fourth of the arm length in both the second and third trimester fetuses. The data presented in this study will be of use to surgeons, particularly to pediatric and orthopedic surgeons who will undertake surgical procedures in the axilla and arm in the newborn or early childhood.

    Anatomy education in medical schools has always been considered demanding, as students need to learn and remember vast amount of information about the human body. Since ongoing technological innovation, is changing how humans interact with information, integrating the web in anatomy education can provide students a way to revise what they have learned in an interactive and competitive means. There has been research on the use of game-based response systems to engage learners during lectures
