title: Correction of Age-Related Midface Volume Loss With Low-Volume Hyaluronic Acid Filler.
abstract: OBJECTIVE
  The pivotal approval trial for a smooth, highly cohesive, viscous, 20-mg/mL hyaluronic acid filler demonstrated sustained aesthetic improvement, with a mean injection volume of 6.65 mL. In daily practice, however, it is not often practical or necessary to use large injection volumes to achieve the desired cosmetic outcome.
  
  
  OBJECTIVE
  To assess the efficacy, longevity, and patient satisfaction associated with correction of age-related midface volume loss using the low volumes of hyaluronic acid filler more commonly used in day-to-day practice.
  
  
  METHODS
  A 2-center, retrospective cohort study examined medical records of 61 healthy patients who underwent treatment for facial volume loss with hyaluronic acid filler from November 1, 2013, through April 31, 2014. Follow-up visits were conducted at 1, 3, 6, and 12 months after the procedure. Data were pooled from a private facial plastic surgery practice in Weston, Florida, and a private cosmetic dermatology practice in San Diego, California.
  
  
  METHODS
  Patients were treated with hyaluronic acid filler according to the investigator's usual practices.
  
  
  METHODS
  The main outcome measure was patient-graded Global Aesthetic Improvement Scale scores at 1, 3, 6, and 12 months after treatment. Scores range from 1 to 5; 1 indicates very much improved and 5, worse.
  
  
  RESULTS
  A total of 61 consecutive, healthy adult patients (mean [SD] age, 57.4 [12.8] years) with mild to severe facial volume loss were enrolled in the study. A total of 46 patients (75%) were white, 3 (5%) were black/African American, 9 (15%) were Hispanic/Latino, 1 (2%) was Asian/Pacific Islander, and 2 (3%) were other. Three patients (5%) were male, and 58 (95%) were female. Mean initial treatment volume was 1.6 mL. At follow-up, 29 patients (48%) elected to have a touch-up treatment; mean total touch-up volume was 1.4 mL. The patient-graded Global Aesthetic Improvement Scale scores at 1, 3, 6, and 12 months after treatment demonstrated that 73% (41 of 56) to 89% (24 of 27) of the study patients reported being very much or moderately improved. Most patients were rated by investigators on the Global Aesthetic Improvement Scale as very much or moderately improved at the 12-month follow-up. At 12 months after the procedure, 43 of 51 patients (84%) reported satisfaction with their outcome. At all time points, most patients would elect to undergo the procedure again (range, 17 [68%] to 61 [100%]). Adverse events were mild, and all resolved spontaneously within 14 days. At the 2-year follow-up, there were no reports of delayed adverse events.
  
  
  CONCLUSIONS
  Midface volumization using the low volumes of hyaluronic acid filler more commonly used in daily clinical practice is effective and well tolerated.
