A computer-assisted surgical simulation was performed for reduction malarplasty and a surgical guide was designed for later 3D printing. The manufactured surgical guide was introduced to the operation field to guide the surgery; its surgical accuracy was confirmed by comparing five corresponding points from preoperative simulation and postoperative data.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We successfully performed the reduction malarplasty with the surgical guide. The accuracy level of surgery fell to 0.93\u00a0mm of total median difference for the corresponding zygoma points of preoperative simulations and postoperative zygoma.
