In this paper, a geometrical parameter model and finite element analysis were used to study the rationale of the proposed V-Y flap design and the preoperative evaluation of the V-Y flap design. First, a geometric parameter model of the V-Y flap was established to analyze the five key geometric relationships affecting the flap structure and obtain a reasonable plan for the V-Y flap design through the crossing constraint relationship. Second, in order to verify the effectiveness of the V-Y flap design, the suture and release states of the V-Y flap during surgery were evaluated based on a simulation model of the V-Y flap generated by finite element analysis software. The results revealed that the approach proposed in this paper provides a feasible method for clinical V-Y flap design.<\/jats:p>","DOI":"10.1155\/2020\/8723571","type":"journal-article","created":{"date-parts":[[2020,1,11]],"date-time":"2020-01-11T18:31:23Z","timestamp":1578767483000},"page":"1-9","source":"Crossref","is-referenced-by-count":10,"title":["Preoperative
