Brief summary

Objectives 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.

Interventions

BEHAVIORALInjection 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.

Design outcomes

Primary

MeasureTime frameDescription
Volumetric accuracy of HA filler injections using observational methodsBaselinephysicians 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.
Volumetric accuracy of HA filler expulsions over a scaleBaselinePhysicians 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.
