Computer simulation tool for rhinoplasty planning
Rhinoplasty is a collection of surgical procedures performed on nose for the purpose of correcting functional and shape deformities. Nose is a facial feature which naturally draws attention during everyday contact. Any operation performed on nose has to blend well with the other facial features of the face. For this reason rhinoplasty is a type of surgery which requires artistic skills from surgeon as well as surgical skills. In this paper we present an artistic simulation tool which manipulates the shape of the nose on the bases of rhinoplasty procedures to be used during the surgery. Unlike other artistic simulation tools which can modify shape with no constraints, this tool simulates the effect of individual operations. Simulation tool can be valuable only if it predicts the outcome of the surgery with accuracy. Ultimately the outcome of the simulation depends largely on the experience of the surgeon. This is also the case with the tool presented in this study, so with experience the tool can be useful for predicting outcome more and more accurately. In this paper, the mechanical model of the nose and tools used for simulation are discussed. The simulation results are compared with actual rhinoplasty results to see the fidelity of the approach. A flowchart of the decision process and how rhinoplastic simulation together with the ideal nose data can be used to aid actual rhinoplastic surgery is given at the end.
