Item 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 Effect of Adipose Derived Stromal Vascular Fraction on Flap Viability in Experimental Diabetes Mellitus and Chronic Renal Disease(2022) Ozkan, Burak; Eyuboglu, Atilla Adnan; Terzi, Aysen; Ozturan Ozer, Eda; Tatar, Burak Ergun; Uysal, Cagri A.; 0000-0003-3093-8369; 35450516Background The presence of chronic renal disease(CRD) concurrently with diabetes mellitus(DM) increases the flap failure. Adipose derived stromal vascular fraction (SVF) is known to enhance skin flap viability in both healthy and diabetic individuals. The aim of this experimental study was to investigate the effect of SVF on skin flap viability in rats with DM and CRD. Methods 48 Sprague-Dawley rats were separated into four groups as follows: group I (control), group II (diabetes mellitus), group III (chronic renal disease), and group IV (diabetes with chronic renal disease).Two dorsal flaps were elevated. Flaps on left side of all groups received 0.5 cc of SVF, while same amount of plasma-buffered saline (PBS) was injected into right side. On postoperative day 7, flaps were harvested for macroscopic, histopathologic and biochemical assessments. Areas of flap survival were measured macroscopically. Blood level of vascular endothelial growth factor (VEGF) was measured after injection of SVF. Results Macroscopically, SVF has significantly improved flap viability (p < 0.05). Flap viability percentage was lower in DM and CRD groups when compared with healthy control group. In respect of new capillary formation, there was a statistically significant difference between SVF injected flaps and PBS injected sides (p < 0.05). Similarly, VEGF levels were higher in all study groups and there was a significant difference in comparison to control group (p < 0.05). Conclusions The study showed that injection of SVF increased flap viability via endothelial differentiation and neovascularization. In vivo function of stem cells might be impaired due to uremia and diabetes-related microenviromental changes.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 Double Layer Reconstruction of Exposed Cardiac Implantable Electronic Devices in Elderly Patients(2021) Ozkan, Burak; Albayati, Abbas; Yilmaz, Kerem C.; Ciftci, Orcun; Ozin, Bulent; Uysal, Cagri A.; Ertas, Nilgun Markal; 0000-0001-8926-9142; 33542888; AAJ-1331-2021; W-5233-2018Background Elderly patients with multiple comorbidities may not be candidates for cardiac implanted electronic device (CIED) explantation in cases of exposition. Excision of all unhealthy and inflamed scar tissue results in a skin defect that must be covered. Small- to moderate-sized local skin flaps and subpectoral placement of CIEDs have been described in the literature. However, these techniques still could not eliminate the risk of recurrence. In terms of minimizing the recurrence risk, we aim to increase the flap dimensions for getting better circulation and tension-free closure after subpectoral placement. Material and methods Six patients who were operated for a dual-layer reconstruction of exposed cardiac implants between 2017 and 2020 were included in the study. All patients were referred to plastic surgery as soon as the wound biopsy culture results were negative after systemic and topical antibiotic treatment by cardiology department. Results No flap loss or wound dehiscence was seen with a mean duration of 11 months follow-up. Early hematoma was encountered in a patient who was managed with irrigation and drain renewal. One patient developed suture abscess in the second month postoperatively. Knots were removed and wound healed without further intervention. Conclusion Double layer closure of exposed cardiac implants with large breast fasciocutaneous flap after subpectoral placement of pulse generator and leads suggest durable and reliable coverage in elderly patients with multiple comorbidities.Item Practical Things You Should Know about Wound Healing and Vacuum-Assisted Closure Management(2021) Ozkan, Burak; Uysal, Cagri A.; Ertas, Nilgun M.; 0000-0001-6236-0050; 33177445Item Escharotomy for the Face: Facial Aesthetic Subunit Principle-Based Approach(2021) Ozkan, Burak; Ertas, Nilgun M; Uysal, Cagri A.; Haberal, Mehmet; 0000-0002-3462-7632; 0000-0003-3093-8369; 32845003; AAJ-8097-2021Escharotomy is the relaxation of an eschar through longitudinal or horizontal incisions in order to protect regional perfusion. In peripheral areas, such as limbs, trunk, and neck, eschar pressure poses significant issues; it causes circulatory disorder in limbs and potential limb loss, inadequate thoracic expansion in the thorax, and perfusion and oxygenation problems in the neck. To prevent complications, a basic rule of burn surgery is to perform escharotomy incisions quickly and without hesitation. However, the face is not an area in which eschar formation is commonly seen due to its robust vascular supply and patients' protection reflex. Although descriptive drawings and guides for facial escharotomy have yet to be published, relaxation of axial arteries in terms of compression from eschar formation may be needed. Here, we present a case of escharotomy based on facial subunit principles.Item A Practical Cleft Palate Training Model(2020) Ozkan, Burak; Cologlu, Harun; Uysal, Cagri A.; Ertas, Nilgun M.; 0000-0003-3093-8369; 0000-0001-6236-0050; 32309100; AAI-5063-2020; AAJ-2949-2021Educational models are essential for training surgeons and making them familiar with experience- and skill-dependent operations such as cleft palate closure. The development of computer and 3D printer technology has allowed cleft lip and palate models to be produced and used for surgical training. However, these technology-dependent models are not affordable and reproducible for surgeons in developing countries where cleft cases are more commonly seen. Thus, we aimed to create a cleft palate educational model prepared with play-dough and latex. The play-dough is shaped in the form of a palate and the cleft is created by scissors. Then, a latex glove is cut and applied to the dough to mimic the mucosal layer. The combination of the latex glove and play-dough lets the trainee perform surgical markings, incisions, elevation of the flaps, and layer closure. We think this easily producible model might be beneficial for demonstrating cleft types, surgical techniques, and improving surgical skills, especially in developing countries.Item Securing Posterior Auricular Incision with Button Headbands in Prominent Ear Patients Wearing Surgical Masks for Self-protection in the Pandemic(2020) Ozkan, Burak; Uysal, Cagri A.; Ertas, Nilgun M.; 0000-0003-3093-8369; 0000-0001-6236-0050; 32500322; AAI-5063-2020; AAJ-2949-2021In this letter, we describe an attachment on conventional headbands recommended for the postoperative period in prominent ear patients to confidently wear surgical masks without disturbing the posterior auricular incision.Item Sacrifice feast disease: Orf(2020) Ozkan, Burak; Uysal, Cagri A.; Uner, Halit; Ertas, Nilgun M.; 0000-0003-3093-8369; 0000-0001-6236-0050; AAI-5063-2020; AAJ-2949-2021Orf disease is a zoonotic infectious caused by parapox virus transmitted by contaminated meat that entered from the disrupted skin. It is usually seen in butchers, farmers, or people who have contact with meat of infected animals commonly in sacrifice feast in Muslim countries. Two patients who admitted to our clinic with orf disease after sacrifice feast were presented. Orf disease should be considered, especially in sacrifice feast term in our country. It heals uneventfully and unnecessary manipulations should be avoided.Item Clinical Experiences with Closed Incisional Negative Pressure Wound Treatment on Various Anatomic Locations(2020) Ozkan, Burak; Ertas, Nilgun Markal; Bali, Ulas; Uysal, Cagri A.; 0000-0003-3093-8369; 0000-0001-6236-0050; AAI-5063-2020; AAJ-2949-2021Background Closed incisional negative pressure wound treatment (ciNPWT) is one of the promising methods for the prevention of complications in surgical incisions. The mechanisms of ciNPWT have previously been elucidated and in this series, we demonstrate various, as of yet, underreported uses for the technology. Our aim is to share our experience with ciNPWT on various anatomic sites with novel indications. Materials and methods ciNPWT was used in 24 patients. The mean age was 49.6. All the incisions were sutured, clean, and non-infected. Patients' sex, age, comorbidities, anatomic location of the wound, and the indications for ciNPWT were recorded. Results The mean number of applications was three per patient. One suture dehiscence after one session of ciNPWT was encountered in a flap donor site of an infant operated for meningomyelocele. Late-term seroma and hematoma formation were encountered in two patients. No surgical site infection, wound dehiscence, and ciNPWT related complications were seen in other patients. The majority of the applications were on the trunk, lower extremity, pelvis, upper extremity, and scalp respectively. Indications for ciNPWT utilization were preventing dehiscence, seroma, and hematoma formation in the majority of the patients. Conclusion ciNPWT is reliable and effective in the prevention of post-operative wound dehiscence and surgical site infections. It can be used safely in various locations and different indications for preventing complications such as preventing dehiscence in revision surgeries, cerebrospinal fluid (CSF) fistula formation in the scalp, and wound breakdown in chronic corticosteroid use,
