Objective assessment of the accuracy of computer-simulated imaging in rhinoplasty.

Objective: The objective of the study was to evaluate the accuracy by which computer-simulated rhinoplasty images reflect surgical results in 6-month postoperative photographs.

Methods: We performed a retrospective, objective evaluation of 5 features of the facial profile in the computer-simulated images and in the 6-month postoperative photographs of 36 rhinoplasty patients. Data recorded for the nasolabial angle, nasofrontal angle, columella tip angle, columella/infratip lobule ratio, and an established method of assessing tip projection were subjected to statistical analysis by 2-tailed t test and analysis of variance testing.
