Our experiences on the reconstruction of lateral scalp burn alopecia with tissue expanders

INTRODUCTION Cicatricial alopecia is a form of hair loss that causes both cosmetic and psychological concerns. Although tissue expanders are the common approach to reconstruction, no algorithm exists in the literature for this process. In this study, it was aimed to create an algorithm for the reconstruction of lateral scalp alopecias with the goal to achieve better and standardized results. MATERIALS AND METHODS Lateral scalp alopecias were divided into three groups: total lateral alopecia (type I), temporal and sideburn alopecia (type II), and sideburn alopecia (type III). Tissue expanders were placed at the parieto-occipital area in type I defects, parietal area in type II defects, and the temporal region in type III defects. Tissue expanders were used to create flaps that were advanced with 60° rotation, 90° rotation, and no rotation for type I, II, and III defects, respectively. RESULTS Fifteen patients were treated with this algorithm. Using this simple approach, we achieved natural, standardized aesthetic results for each patient, all of whom were satisfied with the final results. CONCLUSION Although the number of case were limited, the ideal and standardized cosmetic results could be obtained by this approach.

Reconstruction of the one-digit foot with an osteocutaneous fibula flap: a case report.

The decision to amputate or reconstruct after high-energy foot injuries is controversial. A 25-year-old male patient was admitted to our clinic with a complex injury to his left foot sustained during a mine explosion, and the second to fifth digits and metatarsals of the left foot had been traumatically amputated before admission to our facility. The complex left foot defect was reconstructed with an osteocutaneous fibula flap during a single session. An osteotomy was performed on the bone segment of the flap, and both lateral longitudinal and transverse arches were repaired. Both aesthetic and functional outcomes were very satisfactory, including independent ambulation, light jogging, and full performance of activities of daily living without limitation. Many factors, including comorbidities, should be considered during the decision-making process of amputating or reconstructing complex foot injuries.

Recurrent Breast Cancer with Cutaneous Metastasis in the Late Term

Meme kanseri kadın popülasyonunda önemli bir morbidite ve mortalite nedeni olup kutanöz metastazların da en sık nedenidir. Meme kanserinin deri metastazları sıklıkla primer malignite alnına komşuluğu nedeniyle göğüs ön duvarına olurken saçlı deri metastazı çok daha nadir ortaya çıkmakta bu nedenle oluşan kitlelerin ön tanısında meme kanserinin metastaz ihtimali gözden kaçırılabilmektedir. Ön tanıdaki yanılmalar ise yetersiz cerrahi veya ek cerrahi yük oluşumu ile sonuçlanabilmektedir. Bu sunumda saçlı deride kitle nedeniyle başvuran ve piyojenik granülom ön tanısı ile opere edilen fakat histolojik değerlendirmede müsinöz meme kanserinin geç dönem saçlı deri metastazı saptanan bir olgu sunulmaktadır.

The Reverse Fasciocutaneous ALT Flap Harvested From Deeply Wounded and Scarred Area for Reconstruction of the Knee: A Case Report.

Because of limited flap alternatives, soft tissue reconstruction over the knee is a challenging problem for reconstructive surgeons. When accompanied with surrounding tissue damage in major injuries, local flap alternatives are not available and reconstruction is more difficult. In this report, we present the first case in the literature of a patient who had reconstruction by the reverse fasciocutaneous anterolateral thigh (ALT) flap harvested from a deeply wounded and scarred area for soft tissue defect of knee region. It was shown that the ALT flap can be harvested from deeply wounded and scarred thigh and without any major complication and debulking procedure and that ideal cosmetic and functional results could be achieved.

The Effects of Desferroxamine on Bone and Bone Graft Healing in Critical-Size Bone Defects.

BackgroundAutogenous bone grafts are still the criterion standard treatment option in critical-size bone defect reconstructions, and many therapies can affect its incorporation. In this study, it was aimed to research the effects of desferroxamine (DFO) application on bone and bone graft healing due to the effects of osteoblast and osteoclast regulation and stimulation of angiogenesis. MethodsRat zygomatic arch critical-size bone defect model (5 mm) was used as the experimental model. Thirty-two Sprague-Dawley rats (64 zygomatic arches) were divided into 4 groups (16 zygomatic arches in each). In groups 1 and 2, defects were reconstructed with the bone grafts harvested from the other side, and the right arc was named as group 1, and the left was group 2. At group 1, 200 &mgr;M/300 &mgr;L dosage of DFO was injected at the zygomatic arch region starting at the seventh day preoperatively and lasting until the 45th day postoperatively. Group 2 animals were defined as the control group of group 1, and 0.9% NaCl injection was applied. In groups 3 and 4, there was no repair after the formation of defects, and the right arc region was treated with DFO, and left was treated with 0.9% NaCl for postoperative 45 days, respectively. Radiological (computed tomography), histological (hematoxylin-eosin), and biomechanical (3-point bending test) tests were used for the evaluation. ResultsIn radiological evaluation, there was a statistically significant decrease (P < 0.05) in bone defect size in group 3 animals at the 4th, 8th, and 12th weeks, and bone graft volume showed a statistical difference at all weeks (P < 0.05). In histological evaluation, it was observed that there was an increase in osteoblast number and vascularity rates (P < 0.05) in the DFO-treated groups at all weeks. Biomechanical evaluation of the subjects showed increase in bone strength in group 1 animals at 12 weeks. ConclusionsIn this study, it was shown that DFO treatment increased bone graft incorporation and healing in critical-size bone defects. In this aspect, we suggest that DFO can be used to increase graft incorporation in risky areas and reduce the defect size in patients who are not suitable for vascularized bone graft transfer.

An Extraordinary Case of Axillary Contracture: Trapped Healthy Skin and Its Adnexes Under Contracted Scar

Although striking improvements have been achieved in overall management of burn injury, postburn contractures are still an ongoing challenge to burn surgeons. Axillary adduction contracture is one of the most common types of these disabling postburn complications that usually result from suboptimal treatment after acute burns. An unusual and complicated case of axillary contracture in which the unburned, healthy axillary dome skin was trapped as a cystic mass under the scarred area was reconstructed by transfer of a big (17×13-cm) thoracodorsal artery perforator flap after contracture release. The result was satisfactory in terms of function and acceptable cosmetically. The underlying reasons for the inadequate treatment the patient received after surviving a severe electrical injury were discussed.
