3D photo measurement of facial symmetry after lower or middle face reconstruction
Official title: Development, Validation and Clinical Application of a Method for Quantitative 3D Assessment of Facial Symmetry After Facial Reconstruction Using Three-dimensional Stereophotogrammetry
Run by Assistance Publique Hopitaux De Marseille · NCT06534970 · Data updated 2026-11-12
Using 3D stereophotogrammetry and questionnaires, this project will see if facial symmetry measurements relate to aesthetic outcomes in adults after reconstruction of the lower or middle face.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) who had reconstruction of the lower or middle third of the face with pedicled or microanastomosed free flaps after tumor, osteonecrosis, or trauma and who had surgery and routine follow-up in the three PROMOD departments at Marseille CHU Conception are ideal candidates.
✕Probably not a fit
Patients who had prior different reconstructions of the same facial region, those who cannot read French, minors, people under legal guardianship, or those who did not receive care at the specified Marseille departments are unlikely to benefit from participating.

What this trial studies
This observational project enrolls adults who underwent reconstruction of the lower or middle third of the face with pedicled or free flaps after tumor resection, osteonecrosis, or traumatic loss. Participants receive three-dimensional stereophotogrammetry imaging and complete questionnaires about aesthetic outcome and quality of life during routine follow-up at the PROMOD cluster in Marseille. The goal is to identify which objective symmetry measures correlate with patient-reported aesthetic results and life impact. Findings aim to inform more personalized surgical planning and early correction of poor aesthetic outcomes.
Why it matters
Potential benefit: If successful, the work could help surgeons predict and prevent poor aesthetic outcomes, improving appearance and quality of life for future patients.
How similar studies have gone: Three-dimensional stereophotogrammetry is an established and reliable technique for measuring facial surface symmetry, but using those measurements to predict patient-reported aesthetic outcomes after complex reconstruction remains relatively novel.
