Comparison of 3D scans and 2D photographs for preoperative analysis and planning of rhinoplasty

Introduction The ongoing development of 3D scanners offers surgeons the possibility of improved facial analysis and visual communication of treatment plans and results with patients. Especially in rhinoplasty, preoperative analysis and planning play a major role. Therefore, the aim of the present study is to compare the preoperative planning of rhinoplasties using 2D and 3D photographs.

Material and methods  A total of ten patients were conventionally photographed preoperatively before rhinoplasty using a digital camera from different, standardized perspectives. At the same time, a 3D scan was taken of all patients using the Artec​ Space Spider 3D photography system. The resulting 2D and 3D photographs were then analyzed by 30 surgeons from different disciplines (ENT, maxillofacial surgery, plastic surgery) and different levels of experience regarding preoperative planning. This was followed by qualitative analysis via a questionnaire.

Results Qualitative analysis revealed no significant difference between 2D and 3D photographs regarding preoperative analysis and planning of rhinoplasty. More experienced surgeons preferred the use of conventional 2D photographs. Summary The results of this study show that the type of photography has no significant influence on preoperative planning on the part of the surgeon. Although simulation and planning using 3D scans is playing an increasingly important role nowadays for better communication and visualization, the technical skill and experience of the surgeon remains of paramount importance for the success of rhinoplasty.
