ABSTRACT
<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>
