Description
Allan Vinícius Martins-de-Barros and co-authors tested in 2026 a smartphone scanning app for measuring facial swelling after jaw surgery. Twenty-one patients had facial models built from phone scans and from computed tomography, which served as the reference. Software compared the surfaces point by point before and after surgery. Accuracy meant closeness to the tomography model, while precision meant consistency between repeated phone scans.
Average distance from the reference stayed near two millimetres both before and after surgery. Repeat phone scans varied more before surgery than afterward in the reported means. Differences between the periods reached no statistical significance for either measure in the study. The lower third of the face showed the largest mismatches between the models. Swelling itself did not degrade scan quality, the authors found. They limit the tool's role to swelling monitoring until surface accuracy improves.
