Abstract
Facial flap surgery depends strongly on thorough preoperative planning and precise surgical performance. To increase the dimensional accuracy of transferred facial flaps, the methods of ultrasound and three-dimensional (3D) surface scanning offer great possibilities. This study aimed to compare different methods of measuring distances in the facial region and where they can be used reliably. The study population consisted of 20 volunteers (10 males and 10 females) with a mean age of 26.7 +/- 7.2 years and a mean body mass index of 22.6 +/- 2.2kg/m (2) . Adhesives with a standardized length of 20mm were measured in various facial regions through ultrasound and 3D surface scans, and the results were compared. Regardless of the facial region, the mean length measured through ultrasound was 18.83mm, whereas it was 19.89mm for 3D surface scans, with both p <0.0001. Thus, the mean difference was 1.17mm for ultrasound measurements and 0.11mm for 3D surface scans. Curved facial regions show a great complexity when it comes to measuring distances due to the concavity and convexity of the face. Distance measurements through 3D surface scanning showed more accurate distances than the ultrasound measurement. Especially in complex facial regions (e.g., glabella region and labiomental sulcus), the 3D surface scanning showed clear advantages.
