Study of 3D reconstruction technique in flap design of reconstructed digits for the additional plastic surgery
Objective This study aimed to introduce a new method using 3-D reconstruction and CAD（computer aided design）techniques to evaluate the morphological difference between second toe and fingers. Methods The plaster models for the first to fourth fingers and second toe in the right side of 20 healthy persons were included in the study. To get the 3-D reconstruction data of these models with helical CT set. Software was used to simulate the toe pulp flap harvesting surgery and flap transplantation, and the 3-D configuration of flap was obtained. Results The simulant toe pulp flap could be divided into teardrop and elliptical shape. The simulant transfer flap could be divided into crab claw and cross shape. The flaps of the first to fourth fingers from the same person belonged to the some type. Conclusion The new method can provide accurace three-dimensional evaluation of the shape of the flap, which could be used for the preoperative design.
