Purpose
Cryotherapy
after orthognathic surgery is essential for the control of facial edema. The
aim of our study is to evaluate the efficacy of Hilotherapy face mask in
reducing facial edema after orthognathic surgery, studying facial surfaces with
an innovative, fast, economical 3D facial scan system based on an iPhone app.
Methods
Eighty-four
patients with Class III were included: 35 patients treated with Hilotherm after
orthognathic surgery (Group 1), 32 patients with ice packs (Group 2), 7
patients who refused cryotherapy (not 1 - not Group 2). Their facial scans
performed immediately after surgery (T0), at 24 (T1), 48 (T2) and 72 h (T3)
after surgery, were acquired in specific software, and the discrepancies
between them were studied in an accurate 3D volumetric method.
Results
We
measured a significantly better edema trend in Group 1 in the tragus–nasal wing
line and in the tragus–labial commissure line at T1, and also in the tragus–menton
line at T2 and T3.
Conclusions
In
conclusion, Hilotherapy represents a more comfortable and more effective
cryotherapy system in controlling the trend of facial edema after orthognathic
surgery. The method we used for the facial scans is accurate, cheap, smart, and
fast. As demonstrated by the 3D volumetric study of the face, the regions of
the middle third of the face are those in which the difference is most
noticeable.
