Abstract
Handheld 3-dimensional surface imaging (3DSI) devices of various precision are becoming more versatile in their applications and more widely accepted by clinicians for documentation. The authors sought to compare the precision of facial volumetric change measurements of 3 3DSI devices in the cadaveric model: Eva (Artec 3D Inc., Luxembourg), Sense (3D Systems, Rock Hill, SC), and iSense (3D Systems, Rock Hill, SC). A total of 336 scanning and analysis procedures were carried out in 4 cephalic specimens (mean age, 77.25 24.3 years;mean BMI, 21.76 6.6 kg/m(2)). Two superficial and 2 supraperiosteal regions of interest were injected with 0.5-cc aliquots and subsequently scanned using the 3 different scanners. Correlation coefficients between the injected and measured volume were computed. The correlation coefficient for the Eva scanner was for subcutaneous regions of interest r(p) = 0.935 and for the supraperiosteal regions of interest r(p) = 0.966, compared with r(p) = 0.760 and r(p) = 0.364 (superficial vs supraperiosteal) for the Sense and r(p) = 0.694 and r(p) = 0.382 (superficial vs supraperiosteal) for the iSense scanner. 3DSI devices are capable of measuring surface volume changes of the face at a level of 0.5-cc surface volume change and can thus be regarded as useful tools in the preinterventional, intrainterventional, and postinterventional phases of a treatment. One of the 3 evaluated scanners provided very high correlation coefficients between the injected and the measured volume (Eva), whereas the other evaluated 3DSI devices provided moderate (Sense) and low (iSense) coefficients.
