The purpose of this study is to introduce a breast reduction technique designed to reduce the incidence of postoperative nipple-areola complex ischemia and necrosis following reduction mammoplasty, while at the same time allowing all the other goals of breast reduction to be realized. This is achieved through preoperative detection of perforating vessels supplying the nipple-areola complex using a hand-held Doppler. The horizontally based parenchymal pedicle is designed to include these perforators whether originating from the internal mammary artery, lateral thoracic artery or both. This technique provides freedom in pedicle shaping and fixation to the pectoral fascia to achieve the best breast contour. The study included 50 patients equally divided into two groups: the study group (using preoperative Doppler for detection of perforators) and control group (without preoperative Doppler). The average body mass index of our patients was 32.4 and 29.8 for study and control groups, respectively. The average suprasternal notch to nipple distance was 40.8 cm in the study group and 38.9 cm in the control group. In all cases of the study group, both medial and lateral pedicles were used each of them containing one perforator. The average resection weight per side was 1433.6 g for the study group and 1173.2 g for the control group. None of the study group cases experienced NAC necrosis, while four cases of the control group experienced NAC necrosis (3 partial and 1 total). The horizontally based parenchymal pedicle constructed with the aid of preoperative perforator identification with a Doppler is an effective technique for breast reduction that results in a very low rate of postoperative ischemia and necrosis of the nipple-areola complex.

Introduction Hypertrophic scars are fibroproliferative disorders, seen after burn, trauma, and/or surgery. We aimed to compare the clinical and histopathological results of 1064-nm Nd:YAG laser and combined intense pulsed light and radiofrequency in the treatment of hypertrophic scars. Methods Fifty patients with hypertrophic scars were included in this prospective, randomized study. Twenty-five patients were treated with Nd:YAG laser and 25 patients with combined intense pulsed light and radiofrequency (E-light). The scars were evaluated at baseline, during and at 3 months after the final treatment session using the Vancouver scar scale. Biopsy specimens from scars were obtained before, during, and 3 months after the final treatment session and were stained with hematoxylin and eosin stain, Masson's trichrome stain, and immunostaining procedures for collagen I, collagen III, and TGF-β1. Results Significant improvements in the total Vancouver scar scale scores before and after the treatment in both groups (P < 0.001); however, a significant difference between both groups (P < 0.001), regarding the E-light, which showed better response than Nd:YAG laser. Hematoxylin and eosin and Masson's trichrome staining showed arrangement and thinning of collagen bundles and reduction in collagen density by in both groups, but the collagen bundles thinning and parallelism were more obvious in the E-light group. Significant decrease in the concentration of collagen I, collagen III, and TGF-β1 in the E-light group as compared with the laser group (P = 0.005, P = 0.003 and P < 0.001, respectively). Conclusions Both modalities were successful in the treatment of hypertrophic scars; however, a significant improvement in the clinical and histopathological findings was detected with the E-light method.
Congenital melanocytic nevi, reported in 1% to 6% of newborns. There are many complications the most dangerous is the malignant transformation, but the most depressive is the cosmetic one specially for facial lesions. There is a wide range of treatment modalities none of them provide an acceptable solution for facial lesions. In this study we provide a simple, cheap and effective treatment modality for nasal and perinasal congenital melanocytic nevi. In our study, significant improvement was observed with no repigmentation throughout the follow-up period. We conclude that carbon dioxide cryotherapy is an effective treatment modality for nasal and perinasal congenital melanocytic nevi that should be used by others to stand on its long-term persistence and possible complications.
BACKGROUND Functional and cosmetic outcomes affect reconstruction of the face more than any region of the body. To use a predetermined perforator flap freely designed allowing a wide range of movement and manipulation can give us an optimum outcome. We present our clinical experience with free style facial perforator flaps, surgical technique, and complications. METHODS Thirty patients with post-tumor resection of the face were reconstructed with free style local perforator flaps between January 2014 and November 2016. Doppler was used to identify the perforator vessels preoperatively. RESULTS Twenty-two clinical cases had no complications. Four had venous congestion that resolved spontaneously, three had a distal 1/3 superficial necrosis, and one suffered from hematoma. CONCLUSION Freestyle perforator flaps were applied to get better cosmetic facial reconstruction, allowing one stage procedure and decreasing donor site morbidity. Modern anatomical understanding, good planning, and meticulous surgical technique can affect clinical results.
