Preoperative Evaluation of V-Y Flap Design Based on Computer-Aided Analysis

Abstract EN

V-Y flap is widely used in plastic surgery as an important technique for reconstructing deformities and improving appearance.

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.
