Scalp flaps pedicled with superficial temporal vessel and hair removal for reconstruction of facial skin defects / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the therapeutic effect of scalp flaps pedicled with superficial temporal vessel and hair removal for reconstruction of facial skin defects.</p><p><b>METHODS</b>From Jan. 2010 to Dec. 2011, 6 cases with large facial skin defects were treated with scalp flaps pedicled with superficial temporal vessel and hair removal. At the first stage, the skin expanders were implanted subcutaneously at the homolateral side according to the defect size. After the expansion was finished, the expanded flaps pedicled with superficial temporal vessel were used to reconstruct the facial skin defects at the second stage. 2 weeks after operation, hair removal was performed to remove the hair on flaps. 4-6 treatments were needed.</p><p><b>RESULTS</b>Seven flaps in 6 cases were survived completely. The wounds at donor sites were closed directly. The effect of hair removal was reliable. The patients were followed up for 6 months to 1 year. The flap color, texture and thickness had a good match with surrounding skin tissue.</p><p><b>CONCLUSIONS</b>It is a good option to reconstruct facial skin defects with scalp flaps pedicled with superficial temporal vessel and hair removal.</p>

Effect of high frequency electrocoagulation by ultrafine-needle on the cutaneous capillary hemangiomas: a preliminary study on cock combs / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the injury effect of high frequency electrocoagulation (HFE) by ultrafine-needle on the cutaneous capillary hemangiomas by histopathologic study of cock comb.</p><p><b>METHODS</b>32 male cocks were randomly divided into 4 groups with 8 animals in each group. 3 experimental groups received HFE with different power (6W, 8W, 10W) on the cock comb. Specimens were taken from cock combs for histologic study immediately after treatment and 7, 14, 21, 28 days later.</p><p><b>RESULTS</b>After treatment, the cock combs turned pale and followed with scar formation. The shape of combs changed a lot after high power treatment. Immediately after treatment, the capillary number in the experimental groups decreased markedly under light microscope, compared with that in control group (P < 0.05). After that, the capillary number in experimental group increased. 7 days after treatment, the capillary number in experimental groups was still significantly lower than that in control groups (P < 0.01), but not markedly different between the three experiment groups (P > 0.05). Collagen formation also increased after treatment (P < 0.05), which was higher in experimental groups with high power (P < 0.05, correlation coefficient r > 0.5).</p><p><b>CONCLUSIONS</b>HFE with ultrafine needle can effectively decrease the capillary number in cock comb. The 6W treatment is mini-invasive and will not destroy the comb shape with good cosmetic results. The technique may be used for the treatment of cutaneous capillary hemangioma.</p>

Analysis of unilateral complete cleft lip repaired with skin-vermilion flap method / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce the skin-vermilion flap method repairing unilateral cleft lip and analyze the curative effect.</p><p><b>METHODS</b>We repaired 45 cases with unilateral complete cleft lip by designing a skin-vermilion triangle flap in affected lateral lip to reconstruct the vermilion tubercle, solution, resetting and fixing orbicularis oris muscle, columella nasi and lateral angle of alae nasi, constructing basis nasi, and forming agger nasi between April and December of 2008.</p><p><b>RESULTS</b>All the cases obtained primitively satisfactory effect. The average of follow-up was 3.5 months (rang from 1 to 6 months). All the patients presented obvious agger nasi, good contour of vermilion tubercle and chubby basis nasi. their high-lip, alae nasi and vermilion border were symmetrical between affected and unaffected lateral lip.</p><p><b>CONCLUSIONS</b>Simple design, less expected tissue dose, little scar and good contour of vermilion tubercle are the characteristic of unilateral complete cleft lip cheiloplasty repaired with skin-vermilion flap method.</p>

Repairing alar defects by using a retro-grade island auricle composite tissue flap based on the interconnection of superficial temporal artery and posterior auricular artery / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the application of reverse island auricular composite tissue flap based on the superficial temporal artery for alar defects.</p><p><b>METHODS</b>16 cases with alar defects were treated with reverse island auricular composite tissue flap based on the superficial temporal artery.</p><p><b>RESULTS</b>All the composite auricular flaps survived with primary healing. The patients were followed up for half a year to four years. The survived composite flaps had a similar color, texture and appearance as normal alar. The cosmetic result was satisfactory.</p><p><b>CONCLUSIONS</b>Reverse island auricular composite tissue flap based on the superficial temporal artery is very suitable for alar defects.</p>
