(2021) Ozkan, Burak; Akinci, Kadri; Uysal, Cagri Ahmet; Ertas, Nilgun Markal
The airbag is a lifesaver innovation in automobile industry, but the impact of airbag deployment may cause maxillofacial fractures. Airbag deployment in traffic accidents is a rare etiology of orbital fractures. Although there are reports about airbag-induced orbital fractures in the literature, isolated bilateral blowout fractures have not been published yet. We present a case of isolated bilateral blowout fracture due to airbag deployment in a traffic accident and its management in this study.

(2021) Coskun, Erhan; Ozkan, Burak; Terzi, Aysen; Ozer, Eda Ozturan; Uysal, Cagri Ahmet; Borman, Huseyin; Ertas, Nilgun Markal; 0000-0002-1225-1320; F-7546-2013
Introduction: A prior abdominoplasty is considered as an absolute contraindication to transverse rectus abdominis musculocutaneous (TRAM) flap surgery. The aim of this study is to investigate the effect of nonexpanded adipose stromal vascular fraction (ASVF) on the viability of TRAM flap after abdominoplasty. Materials and Methods: Thirty-five male Sprague Dawley rats were divided into five groups. Reverse abdominoplasty model was used in all groups except Group 1. TRAM flap was performed 2 weeks after abdominoplasty in Groups 2 and 4 and 4 weeks after in Groups 3 and 5. ASVF cells were injected during abdominoplasty in Groups 4 and 5. The viable flap area (VFA) percentage and newly formed perforators were assessed. Capillary density and fibrosis gradient and plasma vascular endothelial growth factor (VEGF) levels were measured. Results: The mean VFA to total flap area was measured as 82.90% +/- 7.59%, 3.31% +/- 3.29%, 9.40% +/- 6.18%, 31.92% +/- 9.29%, and 64.98% +/- 10.95% in Group 1, Group 2, Group 3, Group 4, and Group 5, respectively (P < 0.05). The number of newly formed musculocutaneous perforating arteries was 0.29 +/- 0.49, 1.14 +/- 0.69, and 2 +/- 0.82 for Groups 3, 4, and 5, respectively (P < 0.05). The mean capillary density was 6.86 +/- 0.50, 0.67 +/- 0.13, 2.79 +/- 0.53, 3.71 +/- 0.47, and 7.01 +/- 0.70 in Groups 1, 2, 3, 4, and 5, respectively (P < 0.05). There was a statistically significant increase between the baseline VEGF values and the second VEGF values in Groups 4 and 5. Conclusions: The study showed that local injection of ASVF increases the viability of TRAM flap after abdominoplasty.

A severe electrothermal ring burn case and a proposed treatment algorithm
(2022) Ozkan, Burak; Albayati, Abbas; Savran, Suleyman; Uysal, Cagri Ahmet; 0000-0003-2806-3006; AAC-3344-2021
Ring-associated burns are infrequent comprising only a tiny fraction of burn consults. Due to the circular nature of rings, these burns are often circumferential, with an increased risk for compartment syndrome and neurovascular injury. The severity of ring burn is related to the type of material and electrical current. Low-voltage injuries are generally due to contact with batteries and household devices, while high-voltage electric injuries occur with occupation-related accidents or natural disasters. Low-voltage ring burn can be managed conservatively with close follow-up. However, high-voltage ring burn might have dramatic consequences such as finger amputation. To date, there have been few cases reported in the literature of a ring burn. Most cases were superficial burns and managed with secondary healing or skin grafting. However, the literature has not reported the management of a severe ring burn with deteriorated finger circulation. In this case report, we present a circumferential electrothermal ring burn case with resulted in total loss of a finger. Furthermore, we propose an algorithmic approach to ring burn injuries.
The use of mathematically standardized bilobed design perforator flaps for coverage of sacral pressure ulcers

Background 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.
