An anatomical study on the position of the summit of the zygoma: theoretical bases for reduction malarplasty.

摘要: Background To achieve optimal outcomes in reduction malarplasty, the area of zygoma from which volume should be reduced must accurately identified. This anatomical study aims to evaluate location region that contributes most protrusion cheek. Methods The morphology was studied on 121 Japanese adults (73 men and 48 women). midpoint inferior orbital rim, zygomaticomaxillary junction, junction between frontal process zygomatic arch, lateral rim were marked used as reference points. Then, a vertical plane intersecting anterior posterior edges marked. point distant defined summit zygoma. Three-dimensional measurement using graphic software performed, positional relationships four points evaluated. Results In terms horizontal position, is located medial arch. Regarding exists at higher positions than women. Conclusions Therefore, bone incision lines placed edge malarplasty; effective correction cannot achieved solely by detachment for
