ABSTRACT
Objective@#To investigate the therapeutic outcome of expanded scalp flaps pedicled with superficial temporal vessel for the reconstruction of large facial defects.@*Method@#From Dec 2014 to Oct 2016, 10 cases with large facial skin defects were treated with expanded scalp flaps pedicled with superficial temporal vessel and delayed laser hair removal.Extra expanded scalp flaps were collected as experimental groups. Normal skin(forehead, temporal scalp, cheek, upper eyelid, lower eyelid and nasal dorsum)of 10 cases were collected for control, to compare skin thickness.All patients were followed at least 6 months.@*Results@#There was no significant difference of skin thickness between the expanded scalp flaps and cheek, forehead, nasal dorsum skin(P>0.05). But upper eyelid and lower eyelids skin was significantly thinner than other local skin tissuein controls, and expanded scalp flap (P<0.05). The expanded scalp flap matched well with surrounding tissues in color, texture and thickness.@*Conclusions@#It is a good option to repair large facial skin defects with expanded scalp flaps, pedicled with superficial temporal vessel, and laser hair removal, though its shortcoming in eyelid skin defect repairment.

ABSTRACT
Objective To discuss the treatment method and effect of the application of the dorsal branches island flaps of the digital arteries in clinic.Methods During January,2010 to February,2015,a total of 20 cases of palmar soft tissue defect of the 2nd-5th distal segments of single fingers were incorporated and repaired by the dorsal branches island flaps of the digital arteries in the base of the distal phalanx.The size of the selected flaps was 3.5 cm × 2.5 cm-2.0 cm × 2.0 cm.In addition,palmar soft tissue defect (n =15) of the 2nd-5th middle and distal segments of single fingers were repaired by the dorsal branches island flaps of the digital arteries at the 1/3 site of the proximal digital arteries,and the selected flaps size was 4.5 cm × 2.5 cm-3.0 cm × 2.0 cm.Full-thickness skin graft urethroplasty was used in the donor sites.Flap shape,texture,sensory recovery and texture of the skin region,function recovery of the wounded fingers were followed up at 1,3,and 6 months after operation.Results Thirty-five patients were followed up from 6 to 13 months (average of 7 months).All flaps survived completely in the incorporated 35 cases postoperatively.Flaps had satisfactory appearance,fine texture,and soft texture in the skin transplantation area.The postoperative improvement of sensory function was between S2 and S3,and the two-point discrimination was 10-15 mm.Assessment of the upper limb function using the standard issued by the Hand Surgery Society of Chinese Medical Association graded 23 cases as excellent,10 cases as good,and 2 cases as fair.Conclusion The dorsal branches island flaps of the digital arteries are characterized by easy dissection,reliable blood supply,and no major blood vessels needed to be sacrificed,which is an effective procedure for finger soft issue defect repairing.
ABSTRACT
Our objective was to evaluate the effectiveness of skin-stretching devices for closing defects on the extremities of dogs. Antebrachial skin defects were created on the limbs of 24 dogs randomly divided into three groups. Skin stretchers included staples and sutures passing through them (group A), sutures and hypodermic needles (group B), and Pavletic device (group C). Wounds on the left were further undermined in all groups. Tension and blood perfusion were assessed. After removing the stretchers on day 3, the defects were sutured and wound healing was clinically scored. Histological variables evaluated were cellular infiltration, edema, collagen orientation, and thickness of epidermis. Significant differences in tension were found among groups (p < 0.0005) and between measurement times for undermined (p = 0.001) or non-undermined (p < 0.0005) wounds. In contrast, blood perfusion values did not differ significantly. Clinical scores for group B seemed to be better than those for groups A and C, but differences were not significant. Primary wound closure using the Pavletic device was not feasible. No significant differences in histological variables were found between groups. Skin stretching with staples or hypodermic needles resulted in successful wound management with minor side effects on skin histology and circulation.

MIDAS syndrome (microphthalmia-dermal aplasia-sclerocornea) is an X-linked dominant genetic disease. In most patients, the unbalanced translocation or deletion of the X chromosome short-arm 22.3 band is observed. This disease characteristically presents as linear atrophy of the skin limited to the face and neck, accompanied by congenital eye disease. A 9-month-old female who had linear skin atrophy on the right side of her chin visited our clinic. She also presented with microphthalmia and sclerocornea on her right eye. Results of a chromosomal study revealed a deletion of the X-chromosome short-arm 22.31 band. Here, we report on this MIDAS syndrome patient with linear skin atrophy on the face.

Objective To explore the effect of intraoperative tension adjustment and postoperative scar formation in the treatment of circular skin defects using modified purse-string suture.Methods Twenty-eight cases of circular lesions in the face region were selected and resected along the edge.We first used purse-string suture technique to reduce the circular defect area,and then closed the wound with linear suture in random direction.After 7 days,the stitches were removed and longterm follow-up effects were observed.Results All patients had no facial organ deformation and displacement,the length of the linear scar lesions was shorter than the preoperative length.In 28 cases,one patient's surgical wound was dehisced after removal of stitches in 24 h,and the rest of the skin defects healed after operation in stage Ⅰ.All cases were followed up for 3 months to 1 year,and had a satisfactory therapeutic effect.Conclusions Modified purse-string suture can linearly close the dicision in stage Ⅰ,reduce the scar area and maintain the normal morphology and relative position of the nearby organs.
ABSTRACT
BACKGROUND: In the extremities of premature infants, the skin and subcutaneous tissue are very pliable due to immaturity and have a greater degree of skin laxity and mobility. Thus, we can expect wounds to heal rapidly by wound contraction. This study investigates wound healing of full-thickness defects in premature infant extremities. METHODS: The study consisted of 13 premature infants who had a total of 14 cases of full-thickness skin defects of the extremities due to extravasation after total parenteral nutrition. The wound was managed with intensive moist dressings with antibiotic and anti-inflammatory agents. After wound closure, moisturization and mild compression were performed. RESULTS: Most of the full-thickness defects in the premature infants were closed by wound contraction without granulation tissue formation on the wound bed. The defects resulted in 3 pinpoint scars, 9 linear scars, and 2 round hypertrophic scars. The wounds with less granulation tissue were healed by contraction and resulted in linear scars parallel to the relaxed skin tension line. The wounds with more granulation tissue resulted in round scars. There was mild contracture without functional abnormality in 3 cases with a defect over two thirds of the longitudinal length of the dorsum of the hand or foot. The patients' parents were satisfied with the outcomes in 12 of 14 cases. CONCLUSIONS: Full-thickness skin defects in premature infants typically heal by wound contraction with minimal granulation tissue and scar formation probably due to excellent skin mobility.

PURPOSE: The typical reconstructive option for the nasal tip is paramedian forehead flap. However, the forehead flap is too bulky for nasal tip reconstruction and does not look natural, and therefore, secondary operations for debulking are required. METHODS: We treated a 46-year-old woman who suffered from a nose tip soft tissue defect using a modified paramedian forehead flap. The flap was elevated from the hair line of the forehead and had 3-layered structure. The distal part included skin and subcutaneous tissue, the middle part included frontalis muscle, and the proximal part had periosteum. RESULTS: The nasal tip was not bulky and looked natural in terms of height, shape, and had 3-dimensional structure without debulking procedure. The patient was satisfied with the outcome. CONCLUSION: The authors' modified paramedian forehead flap may be a useful option for the treatment of nasal tip, columella, and alar defects. With these modifications, the paramedian forehead flap can provide an aesthetically acceptable nasal tip appearance without debulking.

Background: A new type of fasciocutaneous flap with the shape of an ice cream cone that is formed by locally rotated and V-Y advance flaps joined together, that can be used to cover complex defects, was developed. Previously, the irrigation of these flaps was ascertained in the legs of ten corpses. Aim: To report the results with the use of this type of ice cream cone shaped flap. Material and Methods: Retrospective analysis of 108 patients aged 20 to 52 years (99 males) in whom an ice cream cone shaped flap was used. Results: The defects covered were located in the leg in 27 percent, in the ankle in 10 percent, in the sole in 9 percent, in the heel in 8 percent and in other locations in the rest of patients. Eighty flaps (74 percent) had a good evolution, 11 (10 percent) had a major dehiscence, 13 (12 percent) had a minor dehiscence and 4 flaps (4 percent) had necrosis. Conclusions: This ice cream cone shaped flap is easy to use, safe and devoid of complications in most cases.
Se presenta un colgajo no descrito previamente en la literatura internacional ni nacional. El colgajo se denomina "en cono" por la forma final que se obtiene un barquillo de helado con su bocado. Consta de 2 colgajos acoplados: uno de rotación local y otro un avance en V-Y, ambos fasciocutáneos. Para comprobar su irrigación se practicó disección anatómica de las piernas de 10 cadáveres frescos inyectando azul de metileno y bario en la arteria poplítea. El resultado demostró un rico y amplio plexo tanto infra como supra fascial que irriga muy bien la piel de ambos colgajos a nivel de 1/3 distal de la pierna. Se realizó también un análisis geométrico del avance en V-Y para demostrar como los tejidos pueden avanzar y para determinar las dimensiones que debe tener este colgajo. Se operó 108 pacientes con lesiones en diferentes partes del organismo con complicaciones de un 3,7 por ciento. Los resultados permitieron determinar que el colgajo en cono es versátil, reproducible, sencillo y seguro de realizar. Es un colgajo que servirá para que los cirujanos plásticos resuelvan complejos problemas quirúrgicos en forma muy segura y a bajo costo.

For treatment of full thickness skin defects caused by trauma or infections, skin grafts or flaps have been the treatment of choice to date. However, in patients who are not candidates for surgery, either due to his general conditions or refusal to receive treatment, supportive methods have been the only means of care, which inherently caused psychological trauma to the patient due to uncertainties of ultimate outcome and the length of treatment. This study aimed to heal full thickness skin defects through application of topical epidermal growth factor in patients who have received 2 to 3 weeks of conservative management using medifoam B(R) without improvement. Six patients from March 2002 to July 2004 were enrolled. The mean size of defects was 5.4x4.6cm in 4 patients with carcinoma and 6.4x4.1 cm in 2 patients with osmidrosis. Commercially available 0.005% EGFR solution was used, and dressing was performed once daily. All patients benefitted from the use of EGF, with closure of skin defects taking an average of 28 days in cancer patients and 22.5 days in osmidrosis cases. EGF can be used as a supportive mean of treatment in the inoperable patients with skin defects, with resultant hastening of healing shortening duration of treatment.
