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 Quality and Reliability of YouTube Videos for Hand Surgery Training(2023) Savran, Suleyman; Albayati, Abbas; Ozkan, Burak; Uysal, Cagri A.; 0000-0003-2806-3006; 0000-0003-3093-8369; AAC-3344-2021Background Hand injuries might present with exposed tendons, bones, and neurovascular structures, requiring flap reconstruction. Comprehending various flap options for hand injuries requires detailed knowledge, surgical skills, and considerable practice. Surgery residents commonly use web-based learning; one is YouTube for surgical education. We aim to evaluate the reliability and quality of the videos on YouTube for hand surgery training. Methods Video extraction from YouTube were done by keywords on 24 August 2021. JAMA scores and flap reconstruction of the hand-specific scoring system (FH-SS) were used to evaluate the selected videos. Results The mean JAMA score and FH-SS were 1.72 and 8.54, respectively. JAMA scores and FH-SS of the videos from Europe were significantly lower than from America and Asia (p = 0.0001 and p = 0.0063, respectively). The JAMA scores of physicians were significantly higher than that of medical sources (p < 0.0001). Conclusions The low JAMA score and the average FH-SS suggest that YouTube videos are unreliable and poorly qualified for hand surgery residents. The high JAMA score of the physician's videos emphasizes the reliability of YouTube videos depending on the sources. Surgery residents should be skeptical of the information of YouTube videos on surgical education. Level of Evidence: Not ratableItem The use of mathematically standardized bilobed design perforator flaps for coverage of sacral pressure ulcers(2022) Ozkan, Burak; Albayati, Abbas; Tatar, Burak Ergun; Uysal, Cagri Ahmet; https://orcid.org/0000-0003-3093-8369; 36205233Background Sacral pressure ulcer reconstruction is frequently applied in plastic surgery practice. Although perforator flaps are frequently used, recurrence is not uncommon in patients. For this reason, using the as little area as possible during the reconstruction is vital. Therefore, we aimed to describe a mathematically standardized bilobed perforator flap design for sacral pressure ulcer reconstruction with a certain proportion and angle relation between limbs. Methods A total of 17 patients (5 female/12 male)were included in this report. The mean age of the patients was 50.4 years (Ranging from 32 to 79 years). The patients with grade 3-4 sacral pressure ulcers were included in the report. The patients have grade 1-2 sacral ulcers or the other areas of pressure ulcer excluded. The size of the defects ranged from 8 x 14 cm to 5 x 16 cm. For ulcers in the sacral region, we used bilobed flaps that we mathematically standardized. The length of the first limb of the flap was planned 90 degrees vertically oriented according to the distance between the perforator zone to the distal lateral border of the defect. The width of the first limb was kept equal to the length of the defect. The orientation of the second limb of the flap was designed 90 degrees horizontally according to the first limb. Therefore, the lengths of second limbs were calculated as half of the first limb's width, and the widths of second limbs were calculated as 3/4 width of the first limb's width. Results A total of 10 flaps were elevated based on superior gluteal artery perforators, and seven flaps were nourished by inferior gluteal artery perforators. The mean size of the first limb of the flaps was 14.7 x 7.2 cm (Ranging from 8 to 20 x 6 to 13 cm). The mean size of the second limb of the flaps was 6.7 x 5.3 cm (Ranging from 5 to 12 x 4 to 8 cm). The mean size of defects was 10.5 x 7.3 cm (Ranging from 8 to 14 x 5 to 16). The mean rotation angle was 91.7 degrees (ranging from 90 to 100). In the early postoperative period, the hematoma was detected in three patients and evacuated in one patient, resulting in wound separation. Tip necrosis was seen in a patient that was healed by wound care. No total flap loss was encountered. No late-term recurrence was seen during the follow-up. The mean follow-up time was 13.1 months (Ranging from 4 to 24 months). Conclusion Unilateral standardized bilobed perforator can reliably be preferred in medium to large size sacral pressure ulcer defects.Item A descriptive study of facial lacerations presenting to pediatric emergency in Turkey(2021) Albayati, Abbas; Ozkan, Burak; Eyuboglu, Atilla; Uysal, Cagri A.; Ertas, Nilgun M.; https://orcid.org/0000-0003-2806-3006; https://orcid.org/0000-0001-6236-0050; 33394475; AAC-3344-2021; AAJ-2949-2021BACKGROUND: Soft tissue trauma of the face is considered a leading cause of presentation and referral to the pediatric emergency department. The present study aims to evaluate the demographics properties of facial injuries presenting to the pediatric emergency. METHODS: In this study, 1160 patients presented with a simple facial laceration to the pediatric emergency department of Baskent University were reviewed from 2011 to 2017. Patients up to 18 years of age were included. We evaluated demographics about patients' age, sex, the cause of injury, the location of laceration and timing of the injury. Age was categorized according to the National Institute of Child Health and Human Development (NICHD) pediatric terminology into five groups as follows: 0-12 months, 12 months-2 years, 2-5 year, 6-11 year, and 12-18 years. The following analyses were performed to each age group: a number of cases, male to female predominance, timing of injury (e.g., early morning, afternoon, evening, late evening and at night), the place that the injury has occurred (e.g., at home, at school, in sport hall), the cause of injury (fall, hitting a hard subject, sports-related), the location of laceration (forehead, periorbital area, cheek, perioral area, nose, submental area) and the incidence according to the season. RESULTS: Number and relative percentages of cases were as follows: 0-12 months (n=127, 10.9%), 12-24 months (n=113, 9.7%), 3-5 years (n=385, 33.1%), 6-11 years (n=403, 34.7%) and 12-17 years (n=132, 11.3%). The average age of children was 6.5 year (range, 5 month - 17.9 year). The age group 6-11 showed a higher incidence compared to other age groups (n=403, 34.7%). Fifty-three percent of the population was younger than six years and there was a male predominance in all age groups. CONCLUSION: The demographic data provided in this study can be useful in trauma prevention programs which are effective in reducing the incidence, nature and severity of facial lacerations. Parents should be reminded of age-specific preventive measures in injury avoidance.Item The Effects of Adipose Derived Stromal Vascular Fraction and Platelet-Rich Plasma on Bone Healing of a Rat Model With Chronic Kidney Disease(2020) Eyuboglu, Atilla Adnan; Arpaci, Enver; Albayati, Abbas; Uysal, Ahmet Cagri; Terzi, Aysen; Bozalioglu, Sema; Turnaoglu, Hale; Balcik, Cenk; Ozkan, Burak; Ertas, Nilgun Markal; 0000-0002-0781-0036; 0000-0003-2806-3006; 0000-0001-6236-0050; 32784349; AAK-8242-2021; AAC-3344-2021; AAJ-2949-2021Background Chronic kidney disease (CKD) impairs osteoblast/osteoclast balance and damages bone structure with diminished mineralization and results in bone restoration disorders. In this study, we investigate the effects of adipose-derived stromal vascular fraction and platelet-rich plasma (PRP) on bone healing model in rats with CKD. Methods Sprague-Dawley rats were separated into 4 groups. All groups except group I (healthy control) had CKD surgery using 5/6 nephrectomy model. All groups had intramedullary pin fixation after receiving bone fracture using drilling tools. Group II rats were used as control group for CKD. Group III rats received PRP treatment on fracture site. Group IV rats received PRP and stromal vascular fraction treatment on fracture site. Weight loss and blood samples were followed at the time of kidney surgery, third, sixth, and 12th weeks. Bone healing and callus formations were compared, biomechanically, radiologically, histopathologically, and immunohistochemically. Osteoblastic transformation of stem cells was assessed with DiI staining. Results Negative effects of CKD on bone healing were reduced by increasing mechanical, histological, radiological, and biochemical properties of the bone with stromal vascular fraction and PRP treatments. Although thickness of callus tissue delayed bone healing process, it also enhanced biomechanical features and bone tissue organization. Conclusions Platelet-rich plasma and adipose-derived stromal vascular fraction treatments were effective for bone healing in animal model, which can be promising for clinical trials.Item Does methylene blue increases capsular contracture in immediate breast reconstruction with silicone implant? An experimental study(2020) Albayati, Abbas; Ozkan, Burak; Atilgan, Alev O.; Sencelikel, Tugce; Uysal, Cagri A.; Ertas, Nilgun M.; 0000-0003-2806-3006; 0000-0001-8595-8880; 0000-0001-6236-0050; 0000-0003-3093-8369; 33030384; AAC-3344-2021; AAK-3333-2021; AAJ-2949-2021Recently, most of the immediate breast reconstructions following mastectomy are being carried out with the use of silicone implants. In these patients, methylene blue is being used for the detection of sentinel lymph nodes. This experimental study was performed to determine the effect of methylene blue on capsular contracture around breast implants. Thirty-two Sprague Dawley rats were divided into 4 groups. Custom made silicone blocks were placed on the back of animals. In group 1, the incision was closed without performing any additional procedure. In group 2 (control), 0.1 mL of 0.9% normal saline was instilled into the pocket. Group 3 and 4 (study groups) received 0.1 and 0.2 mL of 1% methylene blue, respectively. On postoperative day 60, implants and capsular tissue were extracted. Capsule formation was evaluated both macroscopically and microscopically. The histological evaluation included capsule thickness, inflammation, neovascularization, and fibrosis gradients. Regarding capsule thickness, there were statistically significant differences between groups 1-3, 1-4, 2-3, and 2-4. Although there were more moderate and severe inflammation gradients in groups III and IV, there was no significant difference regarding inflammation severity between control and study groups. In respect of vascular proliferation, there was a statistically significant difference between control and study groups. Similarly, fibrosis gradients were higher in both groups 3 and 4. The study showed that the injection of methylene blue around silicone implants enhanced the formation of capsular contracture. In this case, the degree of contracture was independent of the dose given.Item A Custom-Made Nostril Retainer for Adult Population(2020) Ozkan, Burak; Albayati, Abbas; Akinci, Kadri; Uysal, Cagri A.; Ertas, Nilgun M.; 0000-0001-6236-0050; 32371700Elongation of the stylohyoid process or calcification of the stylohyoid ligament is known as the Eagle syndrome. Mostly, it is seen incidentally on imaging or with extreme suspicion and usually patients are asymptomatic. Surgery is the preferred method in symptomatic patients. Transcervical or transoral methods may be preferred as surgical route. A 28-year-old female patient who had formerly underwent tonsillectomy presented with throat and ear pain. A neck computed tomography was performed, and the patient was diagnosed as Eagle Syndrome. Surgery was recommended. Patient developed transient velopharyngeal insufficiency on postoperative day 4. Ventilation exercise and follow-up was recommended. Complaints of the patient decreased on the 15th day. It should be kept in mind that stylohyoid ligament may be calcified in young age group and middle age group patients with dysphagia or odynophagia, and differential diagnosis should be performed. Another issue is the condition of velofaringeal insufficiency which may occur due to the damage of the pharynx muscles by deep dissection during surgery.
