    An Alternative Frontalis Suspension Technique Triband Suspension-A Modified Garcia's Procedure
    (Lippincott Williams & Wilkins, 2011) Benlier, Erol; Bozkurt, Mehmet; Kulahci, Yalcin; Kapi, Emin; Sahin, Cihan
    Blepharoptosis surgery is one of the most common oculoplastic procedures, and the aim is to clear the visual axis. Many surgical techniques for the correction of ptosis have been described and performed, but the operative approach is based on the extent of eyelid excursion, the amount of levator function, and the degree of ptosis. In this study, the frontalis sling procedure with triband suspension was performed on 32 eyelids of 23 patients. All the patients had visual loss because of blepharoptosis with only 0 to 3 mm of measurable levator function. Postoperatively, the palpebral fissure was increased in all the patients. The purpose of this study was to report the use of a modified frontalis sling procedure for congenital ptosis patients with minimal to no levator function. In conclusion, this modified frontalis sling technique if used maximizes the frontalis muscle, creating sufficient eyelid elevation, with stable effect over time.

    An alternative procedure for conjunctivodacryocystorhinostomy - Supratrochlear artery-based island flap combined with buccal mucosal graft
    (Lippincott Williams & Wilkins, 2008) Benlier, Erol; Bozkurt, Mehmet; Kulahci, Yalcin
    Reconstruction of the total canalicular obstruction with destroyed medial canthal area is a challenging procedure for ophthalmic, plastic, and reconstructive surgeons. In the case presented, a supratrochlear artery-based island flap combined with a buccal mucosal graft was used for reconstruction of the medial canthal area. The medial canthal area was scarred significantly and demonstrated a medial ectropion and complete canalicular obstruction. To our knowledge, it is the first time for combined reconstruction of the medial canthal area and lacrimal drainage system in 1 stage, with island median forehead flap based on supratrochlear artery and buccal mucosal graft. During the 2-year follow-up period, no complication was encountered and the patient healed uneventfully.

    (Taylor & Francis Ltd, 2014) Bozkurt, Mehmet; Kapi, Emin; Kulahci, Yalcin; Gedik, Ercan; Ozekinci, Selver; Isik, Fatma Birgul; Celik, Yusuf
    Free radicals are chemicals that play roles in the etio-pathogenesis of ischaemia-reperfusion injury. Various antioxidants have been used in an attempt to mitigate the damage induced by these chemicals. In the present study, the antioxidative effects of grape seed extract (proanthocyanidin), tomato extract (lycopene), and vitamin C (ascorbic acid) on a composite re-established-flow inferior epigastric artery based rectus abdominis muscle-skin flap model on which experimental ischaemia was induced were investigated. The rats have been administered antioxidants for 2 weeks prior to the surgery and for 2 more weeks thereafter. Macroscopic, histopathological, and biochemical analyses were carried out at the decision of the experiment. It was found that flap skin island necrosis was significantly reduced in the proanthocyanidin, lycopene, vitamin C groups (p < 0.001). Statistical analyses showed significant decreases in inflammation, oedema, congestion, and granulation tissue in the proanthocyanidin and lycopene groups compared to the vitamin C and control groups (p < 0.001). When the viability rates of fat and muscle tissues were examined, significant improvements were found in the proanthocyanidin and lycopene groups in comparison to the other groups (p < 0.001). Serum antioxidant capacity measurements revealed significant differences in the lycopene group compared to all other groups (p < 0.001). It is concluded that lycopene and proanthocyanidin are protective antioxidants in rat composite muscle-skin flap ischaemia-reperfusion models.

    Burn Injuries Related to Liquefied Petroleum Gas-Powered Cars
    (Lippincott Williams & Wilkins, 2008) Bozkurt, Mehmet; Kulahci, Yalcin; Zor, Fatih; Kapi, Emin
    Liquefied petroleum gas (LPG), which is used as a type of fuel, is stored as a liquid under high pressure in tanks. Immediate and sudden explosion of these tanks can release a large amount of gas and energy into the environment and can result in serious burns. In this study, the cases of 18 patients injured due to LPG burns in five incidents were examined, along with their epidemiologic features. The authors also investigated the causes of the LPG tank explosions. Inhalation injury was present in 11 cases with varying degrees of severity, and 7 patients subsequently required mechanical ventilation. The explosions resulted from weakening of the tank wall (n = 2), crash impact (n = 2), and gas leakage from the tank (n = 1). LPG-powered cars are becoming more popular because of their lower operational costs. However, LPG tanks can be hazardous in the event of a tank explosion. Burns caused by explosions of the LPG tanks in cars have significant mortality and morbidity. This danger must be taken into account and public awareness must be increased.

    Epidural needle for recipient site preparation in hair restoration surgery
    (Wiley, 2011) Zor, Fatih; Kulahci, Yalcin; Sever, Celalettin; Bayram, Yalcin; Benlier, Erol; Bozkurt, Mehmet
    Background The mini- and micro-grafting method is still one of the most current treatment methods for male pattern baldness and female androgenic alopecia. The preparation of the recipient area with 16G needle has been reported in the literature. However, during the insertion of grafts, the neighboring grafts tend to `pop out'. The study presents our experience in the hair implantation for recipient site preparation with 16G epidural needle. Methods The 16G epidural needle was used during preparation of the recipient field in eight patients. Approximately 500 micrografts were grafted in each patient to reconstruct the anterior hairline. Results During insertion of the micrografts, almost none of the previously inserted grafts tended to `pop out'. The anterior hairline of the patients was natural without obvious scarring. The mean follow-up period of these patients was 1.5 years. The amount of graft survival was found to be satisfactory. Conclusion According to the surgeon's clinical observations, application of this technique was found to be easier than standard needle techniques. It can be used by inexperienced surgeons. Use of epidural needle for recipient hole preparation works well in reducing the popping out, and the curved fashion of the holes reduced the angle of the hair follicle.

    MICROSURGERY AND ANESTHESIA
    (Medknow Publications & Media Pvt Ltd, 2009) Kulahci, Yalcin; Bozkurt, Mehmet; Sen, Huseyin; Zor, Fatih; Ekinci, Safak; Uygur, Fati; Sever, Celalettin
    In reconstructive microsurgery the use of free flap techniques has brought a new dimension to the repair of soft and bone tissue defects. The free-flap procedure is time-consuming and requires special skills of the surgical team as well as adequatelly controlled anesthesia in patients. However there are still arguments in decision making of optimal anesthesia techniques and anesthetics in microsurgery. The aim of this article is to review the topic from the surgeon and anesthetist point of view and expand the researchers' horizons for future research in microsurgery and anesthesia.

    (Springer, 2008) Bozkurt, Mehmet; Kulahci, Yalcin; Zor, Fatih; Kapi, Emin
    The use of the topical tissue adhesive N-butyl-2-cyanoacrylate (Indermil (TM), Tyco Healthcare Group LP, Norwalk, CT, USA) in a 22-year-old male with neurofibromatosis type 1 who was admitted to the emergency room because of uncontrollable bleeding is presented. The topical tissue adhesive was applied to the bleeding from the neurofibromatous tissue. Oozing from the tissue stopped within seconds. Vascular abnormalities associated with neurofibromatosis type 1 must be kept in mind during excision of neurofibroma from the head and neck region. Tissue adhesive may be used in emergency situations such as the case presented here.

    Reconstruction of the Lower Lip in Van der Woude Syndrome
    (Lippincott Williams & Wilkins, 2009) Bozkurt, Mehmet; Kulahci, Yalcin; Zor, Fatih; Kapi, Emin; Yucetas, Altan
    Van der Woude syndrome (VWS) is a congenital disease characterized by labial cysts, accessory salivary glands, congenital lower lip pits, fistula, and paramedian sinuses, and is often accompanied by cleft lip and palate. VWS is an autosomal dominant craniofacial syndrome, which represents only lower lip pits due to variable gene expression. The principles of VWS surgery include excision of lower lip pits and accessory glands, reconstruction of the lip and nose, and correction of accompanying anomalies. In this article, we present a technique with dermal allograft reconstruction to prevent deformities after excision of the accessory gland in the lower lip pit.

    USAGE OF CONDUITS IN PERIPHERAL NERVE REPAIRMENT, CURRENT AND ESSENTIAL MANAGEMENTS: REVIEW OF THE LITERATURE
    (Medknow Publications & Media Pvt Ltd, 2009) Bozkurt, Mehmet; Kapi, Emin; Kulahci, Yalcin
    Peripheral nerve injury is an important cause of patient morbidity today and these injuries continue to be among the most challenging problems faced by surgeons. Important advances in microsurgery, understanding of the details of the biology and chemistry of nerve cell culture, genetic techniques, provides optimism for the improved surgical treatment of peripheral nerve injuries. Primary interfascicular neuroraphy is the most desirable approach for peripheral nerve injuries. If the defects has been, for those defects with significant gaps precluding primary repair, nerve autografting with microsurgical technique is considered standart care. Autografting, however, can be limited due to donor site morbidity. In this respect, included are investigations utilizing different and alternative biologic active materials ant the few clinical applications of the blood vessel, muscle tissue and tubularized membrane. One possible alternative to autogenous tissue replacement is the development of engineered constructs to replace those elements necessary for nerve regeneration, including a scaffold, support cells, induction factors and extracellular matrices. Despite advances in the field of tissue engineering, results to date with nerve conduits have failed to equal the nerve regeneration achieved with autogenous grafts for large distances. Scaffolds is a key element and it is useful as it promotes axonal elongation and it was implanted for intraluminal field of conduits. Many growth factors was described for affecting in the regeneration phase for nerve regeneration. Modification of matrices was building for used are pharmacologic or exogen agents. Additional development of the nerve conduit may lead to further improvements in outcome.
