Item Temporal Muscle Capillary Hemangioma: Case Report(2014) Cologlu, Harun; Ozkan, Burak; Uysal, Ahmet Cagri; Kocer, Nazim Emrah; Borman, Huseyin; https://orcid.org/0000-0003-3093-8369; https://orcid.org/0000-0001-6236-0050; https://orcid.org/0000-0002-5943-9283; AAO-4286-2020; AAI-5063-2020; AAJ-2949-2021; AAM-5436-2021Item Bilateral Propeller Flap Closure of Large Meningomyelocele Defects(2014) Cologlu, Harun; Ozkan, Burak; Uysal, Ahmet Cagri; Cologlu, Ozlem; Borman, Huseyin; https://orcid.org/0000-0002-8605-9032; https://orcid.org/0000-0003-3093-8369; https://orcid.org/0000-0001-6236-0050; 24918736; AAO-4286-2020; AAI-5063-2020; AAJ-2949-2021Background: Meningomyelocele is a defect of the spinal cord, vertebral spine, and overlying skin and is the most common form of spinal dysraphism. Multiple methods of soft tissue closure for larger myelomeningocele defects have been described, including skin grafting, random fasciocutaneous flaps, skin undermining with relaxing incisions, and musculocutaneous flaps. Most current methods for closure of defects of 8 cm and greater and kyphotic spines usually remains inadequate. In this study, we present our clinical experience with a new surgical procedure, bilateral propeller (BP) flaps based on dorsal intercostal and lumbar artery perforator, for the closure of large thoracolumbar meningomyelocele defects. Patients and Method: Between January 2011 and April 2012, 7 newborns (5 males and 2 females) with thoracolumbar large meningomyelocele were included in the study. Six patients had lumbar kyphosis. Myelomeningocele defects with a mean size of 89.3 cm(2) (range, 58.9-136.8) were closed with BP flaps. Results: All flaps survived; hematoma, seroma, wound dehiscence, flap necrosis, or infection was not observed. No patients required any surgical revisions. The patients had a follow-up of 4 to 16 months with a mean of 10 months, and no long-term complications, including necrosis of flap edges, wound breakdown, or instability, have been apparent in our series. Conclusions: We believe that the BP flaps represent a useful tool in the management of soft tissue defects associated with especially kyphotic large thoracolumbar and lumbosacral myelomeningoceles.Item Omega (Omega) Advancement Flap: A Circular Flap Design for the Aesthetic Closure of Circular Skin Defect(2017) Arpaci, Enver; Altun, Serdar; Ertas, Nilgun Markal; Uysal, Ahmet Cagri; Inozu, Emre; 28039499Background Most skin defects that require reconstruction with a local skin flap have a circular-or oval-shaped pattern. The majority of the skin flaps are planned in an angled shape. Therefore, it may be necessary to modify the shape of the defect or the distal flap border to minimize tissue distortion. We have designed a circular-shaped advancement flap to be compatible with the circular defect. Methods Eighteen cases of reconstruction of skin defects in the face, chest wall, hand and buttock area were performed using the omega advancement flap between 2010 and 2014. In this technique, a circular-shaped flap that has an equal diameter with the defect is planned adjacent to the defect. To facilitate the advancement of the flap and to avoid standing cones, deepithelialized equilateral triangular flaps are designed on both sides of the main circular flap. The circular flap is easily moved to the defect by pulling of the triangular flaps with minimal tension. Results All flaps survived without complication such as infection, hematoma or flap necrosis. No secondary surgery was required to correct contour deformities such as standing cones and trap-door deformities. The results were satisfactory aesthetically and functionally. Conclusions The omega advancement flap is an easy and reliable procedure for reconstruction of circular skin defects located on various anatomical regions.Item Aesthetic Surgery in Transplant Patients: A Single Center Experience(2018) Ozkan, Burak; Albayati, Abbas; Eyuboglu, Atilla Adnan; Uysal, Ahmet Cagri; Ertas, Nilgun Markal; Haberal, Mehmet; 0000-0003-3093-8369; 0000-0003-2806-3006; 0000-0002-9805-9830; 0000-0001-6236-0050; 0000-0002-3462-7632; 29528026; AAI-5063-2020; AAC-3344-2021; AIC-3493-2022; AAJ-2949-2021; AAJ-8097-2021Objectives: Transplant patients, like the nontransplant population, can have surgical interventions for body shape disorders. Studies on aesthetic surgeries in transplant patients are scarce. Our aim was to share our experiences with various aesthetic procedures in solid-organ transplant recipients. Materials and Methods: Six (5 female, 1 male) transplant patients who received surgical corrections of the aging face, ptosis and lipodystrophy of the breast, and abdomen at the Baskent University Plastic Reconstructive and Aesthetic Surgery Department between 2010 and 2017 were included. Five patients had renal transplants, and 1 patient had liver transplant. Minimal aesthetic procedures, including botulinum toxin, dermal filler injections, and scar revisions, were excluded. All patients were consulted to transplant team preoperatively and hospitalized in the transplant inpatient clinic. Results: Mean age was 46 years. Aesthetic surgeries included breast reduction (2 patients), high suprasuperficial musculoaponeurotic system face lift (1 patient), blepharoplasty (2 patients), and dermofat grafting (1 patient). Mean hospitalization duration was 2.5 days. Four patients had no minor or major complications. One patient had skin flap necrosis, which healed with secondary intention. Another patient had ectropion after lower lid blepharoplasty, which was corrected with another procedure. Conclusions: Transplant patients are a special group of patients who receive long-term immunosuppressive treatment and medications like high-dose steroids. These treatments can lead to dermal atrophy and cause pseudo-skin laxity. Removal of excess skin and fat tissue should be considered. Efforts should be made to avoid complications such as skin necrosis and unpredictable wound healing problems when resetting the excess tissue. Preoperative consultation with transplant surgeons and keeping operative times short are other important factors. Body dysmorphologies that interfere with normal life activities and demand for younger appearance are the main reasons of aesthetic procedures. Transplant patients can be operated safely with preoperative planning, consultation with transplant surgeons, and close follow-up.Item Nonmelanoma Skin Cancers in Solid-Organ Transplant Recipients: A Single Center Experience(2018) Albayati, Abbas; Ozkan, Burak; Eyuboglu, Atilla Adnan; Uysal, Ahmet Cagri; Ertas, Nilgun Markal; Haberal, Mehmet; 0000-0003-2806-3006; 0000-0003-3093-8369; 0000-0002-9805-9830; 0000-0001-6236-0050; 0000-0002-3462-7632; 29528001; AAC-3344-2021; AAI-5063-2020; AIC-3493-2022; AAJ-2949-2021; AAJ-8097-2021Objectives: Skin cancers are one of the most common malignancies in solid-organ transplant recipients. Increased age and immunosuppressive drug use are risk factors for posttransplant skin malignancies. We evaluated nonmelanocytic skin cancer incidence and development time in transplant patients. Materials and Methods: We reviewed 1833 patients who received kidney, liver, and heart grafts between 1996 and 2016 at Baskent University. We excluded melanocytic skin cancers, premalignant lesions, and benign skin tumors. Results: Of 1833 patients, 1253 were male (68.4%) and 580 were female (31.6%), composed of 1133 kidney (61.8%), 512 liver (27.9%), and 120 heart recipients (6.5%). Of these, 22 patients (18 kidney/3 liver/1 heart) developed 23 different types of skin cancer. Prevalence of skin cancer was 1.20%. Mean age at presentation was 55.8 years (range, 37-71 y). Average time from transplant to skin malignancy was 6.1 years (range, 1-13 y), with the most common being basal cell carcinoma (43%, 10 cases), followed by squamous cell carcinoma (39%, 9 cases) and Kaposi sarcoma (13%, 3 cases). Tumor sites included head and neck (15 case), trunk (2 cases), lower extremity (2 cases), and upper extremity (2 cases). Neither local recurrence nor distant metastasis was shown. Conclusions: Skin cancer risk is increased in solid-organ transplant recipients versus the general population. Although squamous cell carcinoma is the most common tumor in this patient population, followed by basal cell carcinoma, we found this reversed in our patients. The low prevalence of skin malignancy (1.20%) may be associated with close clinical follow- up to detect premalignant skin lesions and the low-dose immunosuppressive drug regimen. We believe that local recurrence and distant metastasis were absent because we use a wide surgical margin of excision and provide strict follow-up. Routine dermatologic follow-up visits of transplant recipients are recommended to detect and treat early skin cancer and premalignant lesions and thus lower morbidity and mortality.Item Extraocular Sebaceous Carcinoma in Muir-Torre Syndrome(2022) Albayati, Abbas; Ozkan, Burak; Ayva, Ebru Sebnem; Uysal, Ahmet Cagri; Ertas, Nilgun Markal; 0000-0003-2806-3006; 36092191; AAC-3344-2021Item Solitary purpuric plaque in a four-year-old girl: Histopathological diagnostic challenge(2022) Uysal, Pinar Incel; Ayvali, Ebru Sebnem; Tepeoglu, Merih; Uysal, Ahmet Cagri; 35593288Item New-onset cutaneous nodule arising from hypertrichotic brownish patch in a 6-year-old girl(2022) Incel Uysal, Pinar; Terzi, Aysen; Uysal, Ahmet Cagri; 35636973Item Successful Replantation of Tamai Zone I Amputation with Delayed Vein Repair(2021) Ozkan, Burak; Uysal, Ahmet Cagri; Markal Ertas, Nilgun; https://orcid.org/0000-0003-3093-8369; https://orcid.org/0000-0001-6236-0050; 33477171; AAJ-2949-2021Digital vein repair is one of the most challenging phases of distal phalanx replantation. Digital veins at very distal levels have a small vessel caliber and collapsed lumens, which makes them hard to identify and handle. Digital veins may not be visible immediately after arterial anastomosis. In this scenario, the patient can be taken to the operative room several hours after revascularization to visualize dilated and expanded veins for late digital vein repair. Late digital vein repair is a reliable and alternative method to artery only replantation. In this report, a successful replantation with late digital vein repair in Tamai Zone I is presentedItem Augmented Reality-assisted Planning of Midpalmar Space Infection of the Hand(2021) Ozkan, Burak; Akinci, Kadri; Savran, Suleyman; Uysal, Ahmet Cagri; Ertas, Nilgun Markal
