Evaluation of Physician Volumetric Accuracy During Filler Injections

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03584347
Recruitment Status : Completed
First Posted : July 12, 2018

Brief Summary:


  1. Evaluate the ability of aesthetic physicians to accurately inject a specific amount (i.e., 0.2cc) of HA soft tissue filler; and
  2. Investigate the effect of different HA gel properties (e.g., G', cohesivity, viscoelasticity) on an injector's performance accuracy.

Official Title: Evaluation of Physician Volumetric Accuracy During Hyaluronic Acid Soft Tissue Filler Injections and the Effect of Products' Biophysical Properties on an Injector's Performance: An Observational, Proof-of-concept Study
Actual Study Start Date : June 3, 2018
Actual Primary Completion Date : June 10, 2018
Actual Study Completion Date : September 3, 2018

Intervention Details:
  • Behavioral: Injection of filler material
    Subjects will be blind folded and asked to deposit 0.2cc's of each of the four investigational products, in a randomized order. First, over a weight and then into a porcine membrane.

Primary Outcome Measures :
  1. Volumetric accuracy of HA filler injections using observational methods [ Time Frame: Baseline ]
    physicians will attempt to inject 0.2CC of four HA products into a porcine membrane. Volumes will be measured in CC's and their accuracy assessed based on the amount of product left in the syringe.

  2. Volumetric accuracy of HA filler expulsions over a scale [ Time Frame: Baseline ]
    Physicians will attempt to dispense 0.2CC of four different HA products. They will do this into free air, over a scale. The weights will be calculated in grams and converted to CC's. The scale is the "Smart Weight" digital milligram scale, JDS20 edition. It's specifications are as follows: capacity: 20g/100ct/308.8gn/12.86dwt; readability: 0.001g/0.005ct/0.02gn/0.001dwt; scale dimensions: 3x5x0.8"; accuracy of 0.001grams and capacity of 20grams.
