    Hyaluronic Acid Viscoelastic Medium as an Aid for Microsurgical Venous Anastomoses
    (Lippincott Williams & Wilkins, 2013) Yazici, İlker; Usta, Gülşah; Boybeyi, Özlem; Onaran, Zafer; Fariz, Sevin
    The thin-walled structure of veins leads them to stay collapsed during anastomoses, thereby the incidence of technical failures is more common than arterial anastomoses. In order to overcome this problem, we are introducing the use of viscoelastic material based on our experience on rats. Six rats were used in order to study the technical feasibility of the viscoelastic material during microsurgical vein anastomosis. End-to-end anastomoses were performed on rat jugular veins using 0.5-1 mL of the viscoelastic medium applied to the ends of the veins and surgical field under X30 operating microscope magnification. Then 1.8% (n:3) and 3.0% (n:3) hyaluronic acid was used as a viscous medium in order to keep the vein lumens open during anastomosis. In conclusion, we have found that 3.0% hyaluronic acid viscoelastic medium facilitates microvenous anastomosis in rat. Studies involving human practice are needed for further evaluation of this technical refinement.

    Simultaneous Reconstruction of Medial Canthal Area and Both Eyelids With a Single Transverse Split Forehead Island Flap
    (Lippincott Williams & Wilkins, 2011) Onaran, Zafer; Yazici, İlker; Karakaya, Esen I.; Çavuşoğlu, Tarık
    In this report, we are presenting a case in which we have split the paramedian forehead flap, thus providing 2 axially perfused skin flaps for simultaneous reconstruction of the upper and lower lid structures after resection of basal cell carcinoma from the left medial canthal area. We found that split forehead flap seems to be a favorable option for simultaneous reconstruction of the upper and lower eyelid defects by enabling nicely vascularized and abundant amount of regional skin.
