Öğe Aesthetic reconstruction of large scalp defects by sequential tissue expansion without interval(Springer, 2004) Gürlek, A; Alaybeyoglu, N; Demir, CY; Aydogan, H; Bilen, BT; Öztürk, ATissue expansion is indicated in the reconstruction of various scalp defects when there is inadequate adjacent tissue to allow either primary closure of the defect or repair with a local flap. It is the most important armamentarium for aesthetic hair-bearing scalp reconstruction in cases of congenital or required defects. This technique was used sequentially without interval to achieve scalp reconstruction for 12 patients with a defect ranging from 30% to 75% of the scalp (average, 55%). For 12 patients, 32 expansion treatments were undertaken between September 1997 and January 2002. The 12 patients included 3 women, 4 men, and 5 children with a mean age of 20 years (range, 45 days to 36 years). All patients had more than one period of treatment. The most common conditions treated were burns (n = 7). trauma (n = 1), congenital naevi (n = 2), and male pattern baldness (n = 2). Reconstruction of 12 large scalp defects has been performed with a 3.1% rate of major complications. Results show that tissue expansion is a safe and efficient but time-consuming technique for aesthetic scalp reconstruction, especially in the case of sideburn scenario or large defects. There was no significant alteration in ratio of complications although tissue expansions were made sequentially.Öğe An easy way of finding a vein in microsurgery(Lippincott Williams & Wilkins, 2003) Gürlek, A; Askar, I; Bilen, BT; Çelik, M; Fariz, A; Aydogan, H; Arslan, A[Abstract Not Available]Öğe Effect of caffeic acid phenethyl ester on survival of axial pattern flaps in rats with ischaemia-reperfusion injuries(Taylor & Francis As, 2006) Bilen, BT; Kilinç, H; Alaybeyoglu, N; Çelik, M; Iraz, M; Sezgin, N; Gültek, AOxygen-derived free radicals have been implicated in the pathogenesis of tissue injury after ischaemia-reperfusion. Caffeic acid phenethyl ester ( CAPE), an active ingredient of honeybee propolis, has been identified as having potent antioxidant and anti-inflammatory properties. We evaluated the ability of CAPE applied intraperitoneally in reducing tissue injury after ischaemia-reperfusion. To investigate whether treatment with CAPE modifies the concentrations of the endogenous indices of oxidant stress, we examined its effects on a model of flap ischaemia-reperfusion injury in rats. CAPE (10 mu mol/ kg) was given through the peritoneum before reperfusion. CAPE given intraperitoneally had an inhibitory effect on tissue injury after ischaemia-reperfusion comparable to that of a control group. The anti-inflammatory and antioxidant properties of CAPE may contribute to its suppression of tissue injury.Öğe Epidermoid carcinoma arising in chronic lymphedema(W B Saunders Co Ltd, 2003) Bilen, BT; Gürlek, A; Alaybeyoglu, N; Çelik, M; Aydin, NELymphangiosarcoma is a well recognized complication of chronic lymphedema, but epidermoid carcinoma is rarely seen.

Mutilation, functional, cosmetic and psychological problems occur when they can not be transplanted or failed after transplantation. Bone lengthening was carried out on 18 digital amputation stumps of 10 patients by distraction osteogenesis (Ilizarov's method) during the period of January 2000 to January 2002. Mean age was 14.2+/-8.1, ranging between 4 and 27 years. The average lengthening achieved 28.4 +/- 83 (15 - 50 mm). Distraction durations varied between 20 -70 (mean 35.2 +/- 8.3) and consolidation between 45 -120 days (mean 74.2 +/- 17.1). Two pin-tract infections, one bone fracture because of trauma, one early fusion of osteotomy and severe pain in two patients due to distraction were observed as complication. Distraction osteogenesis is very effective, simple, no necessity to donor area in the treatment of amputation stumps to get function; in spite of requiring long duration, patience and a good cooperation of both family and patient.Öğe A new approach to retroauricular flap transfer -: Parietal branch-based reverse flow superior auricular artery island flap(Lippincott Williams & Wilkins, 2006) Kilinç, H; Bilen, BTThe retroauricular region provides adequate tissue of excellent color and texture match for the reconstruction of small and medium-sized facial defects. In this study, parietal branch of the superficial temporal artery (STA) was used as the pedicle for the retroauricular island flap. Anastomoses between the parietal branch of STA, occipital artery, and contralateral STA were observed to deliver adequate nutritional blood supply to the flap. Total upper eyelid defect in 1 case, malar defect in 1 case, and forehead defects of various sizes in 4 cases were included in our study. Sizes of the flaps varied from 4 X 4.5 cm to 6 X 8 cm (mean 4.7 X 6.6 cm). All cases had venous congestion for 2-4 days (mean 3.4 days). Only 1 case experienced a superficial dermal necrosis of 1 X 3 cm in size in the distal part of the flap. Esthetic and functional results were satisfactory during the 1 - to 14-month (mean 7) follow-up period. This flap is thought to be advantageous for the repair of defects and traumas of the forehead and upper eyelid as the pedicle does not develop torsion and dissection is easy.Öğe Obstructive congenital gingival granular cell tumour(Elsevier Ireland Ltd, 2004) Bilen, BT; Alaybeyoglu, N; Arslan, A; Türkmen, E; Asian, S; Çelik, MCongenital gingival granular cell tumours; (CGCT) are rare and always benign intraoral tumours originating from the alveolar ridge. They are also known as congenital epulis, congenital myobtastoma or Neumann's tumour. They are typically seen as a mass protruding out of a newborn child's mouth. In general., CGCT occurs as a solitary tumour. The main differential diagnosis is epignathus (oral teratoma). This report describes a newborn with a mass originating from tower alveolar ridge obtruding into the oral cavity. Clinical features, histiogenesis and necessity for early surgical treatment due to risk of airway obstruction and difficulty in feeding were discussed. (C) 2004 Elsevier Ireland Ltd.

Bone (calvarial, iliac crest, costal, nasal hump, ulnar, and heterogenous origin), cartilage (septal, costal, heterogenous), and synthetic materials (silicon, silastic, polyethylene) were used as support grafts. Three patients have been included in this study to define the surgical management and long-term aesthetic and functional results of patients undergoing rhinoplasty with support grafts for a saddle nose deformity. Open rhinoplasty was employed. Both the lower turbinates were excised and the bone dissected from the soft tissues in two cases and in one case, only mucosa was removed. The amount of support needed was measured by using bone wax. The bone was used shaped in layers, according to the defect, and sutured to each other by vycril suture, and wrapped around by surgicell. The graft was then inserted in its place and fixed with external prolene sutures. Results were satisfactory in both function and aesthetics. Ten to 16-month followups had no complications. Saddle nose surgery basically requires the use of a support graft to repair the nasal dorsum. A lower turbinate bone graft procedure has some advantages: it is cheap and safe, it is ready to use and not time-consuming, there is no donor area and no additional donor site morbidity, and it enlarges the airway and the passage to prevent nasal airway obstruction.
