Summary
Reduction malarplasty significantly alters soft tissues, with changes varying across surgical sites. Body mass index did not correlate with these three-dimensional soft tissue outcomes following zygomatic bone reduction.
Area of Science:
- Plastic Surgery
- Craniofacial Surgery
- Aesthetic Surgery
Background:
- Reduction malarplasty aims to reduce prominent cheekbones.
- Understanding soft tissue response is crucial for predictable aesthetic outcomes.
Purpose of the Study:
- To quantify three-dimensional soft tissue changes after reduction malarplasty.
- To assess the relationship between bone movement and soft tissue displacement.
- To investigate the influence of body mass index on soft tissue changes.
Main Methods:
- Superimposition of pre- and postoperative cone beam computed tomography (CBCT) scans from 21 female patients.
- Measurement of soft tissue changes relative to zygomatic bone movement at specific osteotomy points (A, B, C, D).
- Analysis of the proportion of soft tissue change to bone change and correlation with body mass index.
Main Results:
- Mean soft tissue changes ranged from 53.43% (Point A) to 66.66% (Point B).
- Point B exhibited greater soft tissue change than osteotomy sites A and D.
- No statistically significant correlation was found between body mass index and the soft tissue change ratio.
Conclusions:
- Reduction malarplasty induces significant, site-specific three-dimensional soft tissue changes.
- Soft tissue response is not uniform across all surgical landmarks.
- Body mass index does not appear to be a predictive factor for soft tissue changes in this patient cohort.
