Abstract:
Objective To evaluate the value of three-dimensional scanning technology in the preoperative design of tissue expansion procedures,with the expectation of making objective and accurate judgments regarding the timing of the second-stage expanded flap transfer surgery for patients,in order to avoid insufficient or excessive expanded flap areas.Methods From April 2024 to September 2024,we treated 10 patients who planned to undergo local tissue expansion for head and neck reconstruction.We utilized the Vectra WB360 three-dimensional imaging device to measure the wound defect area,the base area of the expander,and the expanded flap area in these patients,and compared these measurements with intraoperative results to assess the accuracy of this technology in guiding tissue expansion surgery.Results In 10 cases,the surface area of the expander(expansion skin area),the base area of the expander,and the lesion area were measured using the Vectra WB360 3D imaging device,with average measurements of(539.3±268.4)cm2,(157.0±78.13)cm2,and(252.8±141.6)cm2.Intraoperative actual measurements were(470.7±230.4)cm2,(159.9±83.2)cm2,and(241.7±134.1)cm2.Statistical analysis revealed no significant differences between the device-measured base area of the expander and lesion area compared to the intraoperative actual measurements(P＞0.05).The device-measured expanded skin area was greater than the intraoperative flap area(P＜0.05),which is associated with the retraction of the expanded skin after the removal of the expander.During the opearation,the flaps were able to completely cover the wound,and all flaps survived postoperatively.Follow-up at 1 to 6 months indicated good recovery of the surgical site's appearance and function,with a high level of patient satisfaction.Conclusion The Vectra WB360 three-dimensional imaging device significantly improves the accuracy of preoperative flap area estimation,optimizes surgical planning,and thereby enhances the success rate of expanded skin flap surgery.
