Abstract:ObjectiveTo explore a new method with patients involved computer-aided design in personalized curved osteotemy of prominent mandibular angle,and to evaluate the feasibility of the method.MethodsPatients with extraordinary surgical expectation were selected.Then the three dimensional virtual skull models with mandibular cannel were reconstructed for 3D measurement and surgical plan making by both doctors and patients themselves.Followed the surgical plan,the personalized curved osteotemy of mandibular angle was conducted.Then the final outcome and effect of operation was evaluated with computer technology.ResultsAll of the 12 patients' personalized surgical plans were laid down, and the patients had high satisfaction after the operations.And there were significant differences between the parameters values of the skulls measurement before and after the operations(P<0.05). ConclusionThe application of patients involved computer-aided design in personalized curved osteotemy of prominent mandibular angle has high clinical guidance value and feasibility to help doctor-patients communication,real surgical practice and assessment of operation outcome.
