Although Botulinum Toxin Type A (BTXA) has been applied to scar prevention and treatment, the mechanisms still require further exploration. <jats:italic>Objective<\/jats:italic>. To investigate the effects of BTXA on microvessels in the hypertrophic scar models on rabbit ears. <jats:italic>Methods<\/jats:italic>. Eight big\u2010eared New Zealand rabbits (males or females) were selected to establish scar models. One ear of each rabbit (4 models in each ear) was selected randomly to be injected with BTXA immediately after modeling and included in the treated group, while the opposite ear was untreated and included in the control group. The growth of scars in each group was observed and recorded, and 4 rabbits were sacrificed on days 30 and 45 after modeling. Then, scar height was measured by hematoxylin\u2010eosin (HE) staining, vascular endothelial growth factor (VEGF) expression was detected by immunohistochemical (IHC) testing, and microvessel density (MVD) was calculated based on CD34 (human hematopoietic progenitor cell antigen). <jats:italic>Results<\/jats:italic>. The wounds in each group were well healed and free from infection or necrosis. On days 30 and 45, the scar height, MVD value, and VEGF expression in the treated group were lower than those in the control group (<jats:italic>P<\/jats:italic> &lt; 0.05). For the treated group, the above indicators on day 45 were lower than on day 30 (<jats:italic>P<\/jats:italic> &gt; 0.05). Besides, there was a positive correlation between the MVD value and the VEGF expression in the treated group (<jats:italic>P<\/jats:italic> &lt; 0.05). <jats:italic>Conclusion<\/jats:italic>. The injection of BTXA immediately after modeling inhibits VEGF expression and reduces angiogenesis, thereby inhibiting hypertrophic scar formation.<\/jats:p>","DOI":"10.1155\/2020\/2170750","type":"journal-article","created":{"date-parts":[[2020,6,16]],"date-time":"2020-06-16T23:31:03Z","timestamp":1592350263000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Effects
