ABSTRACT
PURPOSE:
Reduction malarplasty is one of the most popular procedures for esthetic facial contouring in East Asians. The retrospective observational study aimed to analyze the association between the zygomatic change and bone setback or resection to propose quantitative guidance for L-shaped reduction malarplasty based on computed tomographic (CT) images.METHODS:
A retrospective observational study was conducted on patients who underwent L-shaped reduction malarplasty with bone resection (Group I) or without bone resection (Group II). The amount of bone setback and resection was calculated. The unilateral width changes of the anterior, middle, and posterior zygomatic regions as well as zygomatic protrusion change were also evaluated. Pearson correlation analysis and linear regression analysis were used to analyze the relationship between the bone setback or resection and the zygomatic changes.RESULTS:
Eighty patients who underwent L-shaped reduction malarplasty were included in this study. Significant correlation was observed between the bone setback or resection and the change of anterior, and middle zygomatic width as well as protrusion in both the two groups (Pâ¯<â¯.001). The correlation between bone setback or resection and the posterior zygomatic width change was not significant (P ï¼.05).CONCLUSION:
The bone setback or resection of L-shaped reduction malarplasty lead to the anterior and middle zygomatic width and zygomatic protrusion changes. Furthermore, the linear regression equation can be referenced as a guidance for a preoperative surgical plan.Key words
