The facial grid analysis for filler injection: a cohort study on 300 patients

BACKGROUND: Filler injection is widely used for facial rejuvenation. Global skin rejuvenation requires the precise sequential injections ofdifferent areas, but a standardized and reproducible method is lacking. The purpose of the study was to develop a new method for a precisemeasurement of the degree of facial defect before and after full-face rejuvenation with injectable fillers, so called facial filler (FAFI) grid.METHODS: Three hundreds patients were included. There were 76 males and 224 females with a median age of 30.5 years. A grid of horizontal and vertical lines was drawn on the patients’ face with a rigid meter and a surgical pen to identify some precise areas for sequential filler injections.The grid was also used to measure the defects and the corrections obtained. Three different formulations of hyaluronic acid were used fortreating specific facial areas.RESULT S: Correction was judged adequate in 77% and 90% of cases by the physician and patients, respectively. Prevalence of adverse events was 8.8%, with mostly mild, with resolution in few weeks.CONCLUSIONS: FAFI grid proved to be helpful in guiding sequential injections for total facial rejuvenation
