Purpose
This investigation aims to elucidate the volumetric expansion of injectable facial fillers over time within the periocular region, employing MRI technology to assess actual versus initially injected volumes.
Methods
A cohort of ten patients, previously administered with facial fillers in the periocular areas, underwent quantitative MRI evaluations. This study focused on detailed volume measurements in anatomically critical zones including the tear trough, mid cheek, lower lid, and nasolabial region.
Results
The volumetric analysis revealed that MRI-measured volumes substantially exceeded the initially injected amounts, with measurements indicating an average increase of approximately 208%. Specifically, total MRI-measured volumes varied from 0.7 cm³ to 38 cm³, contrasted with initial volumes ranging from 0.55 cm³ to 11 cm³. This data suggests that fillers expanded to approximately 3.08 times their original volume post-injection.
Conclusion
For the first time, this study documents that injectable facial fillers, particularly within the periocular regions, undergo significant volumetric expansion post-administration rather than gradual diminishment. These findings are critical for medical professionals to accurately adjust dosage and anticipate aesthetic outcomes. Moreover, this underscores the necessity of utilizing advanced imaging modalities such as MRI to guide precise filler applications and forecast long-term volumetric changes in facial aesthetics.
