Öğe Acro-ischemic lesions in COVID-19 patients: A case series(Wiley, 2022) Ozbey, Rafet; Algan, Mehmet FatihCOVID-19 is a systemic disease characterized by vascular damage, increased inflammation, and hypercoagulability. Acral ischemic lesions occur as a result of increased inflammation and cutaneous thrombosis. Skin lesions can sometimes be the only symptom of COVID-19. In this respect, recognizing acro-ischemic lesions, which are skin lesions, may help in the early diagnosis of the disease and in predicting the prognosis. In patients with skin lesions without typical symptoms, the diagnosis of COVID-19 should be kept in mind. Herein, we describe five patients affected by COVID-19 which developed acro-ischemic lesions.Öğe Maksillofasiyal Travmada Periorbital Yabancı Cisim(2022) Fırat, Cemal; Aslan, Göçmen; Algan, Mehmet FatihMaksillofasiyal travmalarda fraktürler, yumuşak dokuda yaralanmalar, doku kayıpları sıklıkla karşılaşılan durumlardır. Travmanın şekline bağlı olarak yaralanma sonucunda cilt altında, derin dokuda yabancı cisimler kalabilir. Yabancı cisimler içeriğine bağlı olarak görüntülemede gözükmeyip günler sonrasında enfeksiyon odağı olarak bulgu verebilir. Kliniğimize geç başvuran olgumuzda 45 gün sonrasında fraktür nedeniyle yapılan operasyon sırasında periorbital bölgede tahta parçaları bulundu. Tahta parçalarının etrafındaki pürülan içerik cilde fistül oluşmasına neden olmuş. Yabancı cisimle kontamine bölge irrige edilerek tüm yabancı cisimler çıkarıldı. Özellikle görüntülemede atlanabilecek tahta yapılı yabancı cisimler akılda tutulmalı, travma sırasındaki hikâye irdelenmeli ve yabancı cisimlerin cilt altında kalmış olabileceği unutulmamalıdır.Öğe Our Clinical Algorithmic Approach for Meningomyelocele Defects Reconstruction with Fasciocutaneous Flaps(Turkish Neurosurgical Soc, 2021) Algan, Mehmet Fatih; Firat, Cemal; Bekircan, Kagan; Kilinc, Hidir; Onal, Selami CagatayAIM: To evaluate fasciocutaneous flaps used for reconstruction of meningomyelocele defects in our clinic and to suggest an algorithm for flap selection. MATERIAL and METHODS: A retrospective analysis of 45 patients with meningomyelocele, who underwent repair with fasciocutaneous flaps, was carried out. Preoperative and postoperative photos were analyzed. The defect areas were measured by Adobe Photoshop CC. Limberg flap, bilateral Limberg flaps, bilateral bipedicled advancement flaps, bilobed flap and reading man flap were performed. RESULTS: Wound dehiscence and partial necrosis occurred in 8 patients. All wounds were managed conservatively and healed successfully. No other complications were observed. The mean defect size for all patients was 36 cm(2). The mean defect size was 45.3 cm(2) in bilateral bipedicled flaps cases; 33.5 cm(2) in bilateral Limberg flaps cases; and 19.6 cm(2) in the unilateral Limberg flap cases. According to the algorithm, a unilateral Limberg flap or bilobed flap or reading man flap can be used for the defects smaller than 25 cm(2); bilateral Limberg flaps can be used for the defects between 25 and 35 cm(2); and bilateral bipedicled advancement flaps can be used for the defects larger than 35 cm(2). CONCLUSION: Fasciocutaneous flaps can be preferred in meningomyelocele defect reconstruction due to the easy planning of flaps, easy and fast flap elevation, and low complication rates due to their reliable circulation. The measurement of the defect area allows this algorithm selecting a flap in a more practical way.Öğe Reconstruction of Hair-Bearing Areas(Lippincott Williams & Wilkins, 2020) Kilinc, Hidir; Algan, Mehmet FatihHair-bearing areas reconstruction is a difficult field because of limited donor area. Various techniques have been described for hair-bearing areas reconstruction, but the choice of the flap is variable depending on surgeons and patients. In this study, the authors present 7 patients who underwent soft tissue reconstruction with the pedicled superficial temporal artery-based flaps in the hair-bearing areas. No postoperative complications like bleeding, flap congestion, wound dehiscence, and flap necrosis were observed. This flap can be an alternative to the other methods because it is compatible with the face by the flap color and thickness, it can be easily harvested, it has a reliable circulation and minimum donor site scar.Öğe Use of an Autologous Diced Cartilage Graft and Fat Graft Combination to Improve Regeneration in Rhinoplasty(Springer, 2021) Firat, Cemal; Bekircan, Kagan; Algan, Mehmet FatihBackground In rhinoplasty, many techniques are used to increase the permanence of the planned final shape of the nose. Cartilage grafts can be diced and applied directly to the nasal dorsum, or by wrapping with a material. We aim to show that mixing and using diced cartilage grafts with fat grafts can contribute to the viability of cartilage grafts by comparing our early postoperative and long-term results. Materials and Methods A total of 228 cases were analyzed. Postoperative 1-month, 6-month, and 1.5-year photographs of the patients were compared and the places that descended on the nasal dorsum were measured. In addition, dorsal height was measured and compared. Preoperative and postoperative first-year rhinoplasty outcome evaluation scales were performed. Specimens from 6 patients were examined histopathologically. Results After the first month, the mean regression in the dorsum was measured as 1.4 mm. The decrease in dorsal height between 1 month and 6 months was significantly greater than the decrease between 6 months and late periods. According to the rhinoplasty outcome evaluation (ROE) scale, the average preoperative score of the patients was 45, while the mean postoperative score was 81.5. The viability of chondrocyte cells was measured as 85-90% histopathologically. Conclusion This approach has been evaluated as an application that satisfies both the surgeon and the patient due to the advantages of fat grafts such as preventing the cartilage and osteotomy lines from being palpated in thin-skinned patients, holding the diced cartilage grafts together by acting as a glue, increasing the viability of cartilage grafts.
