Patient satisfaction is crucial to aesthetic surgery, yet measuring how well outcomes meet patient expectations has always been challenging. Rather than relying on the surgeon’s impression, we’ve synthesized research on Patient-Reported Outcome Measures (PROMs) in facial aesthetics. Our work zeroes in on the FACE-Q instrument and explores newer technological applications. We conducted a comprehensive literature review of studies on facelifts (563 patients across 10 studies), injectable treatments (2292 patients in 23 studies), and rhinoplasty (937 patients across 10 studies). Our original data came from a Dutch cohort of Clinique Rebelle in Amsterdam—259 patients undergoing facial procedures, supplemented by Computerized Adaptive Testing (CAT) simulation research. The FACE-Q scales demonstrated strong psychometric properties—Cronbach’s alpha between 0.885 and 0.951—and successfully captured differences between patients that traditional photos miss. CAT methods reduced questionnaire length by roughly 71% without sacrificing measurement accuracy (r = 0.98 with complete surveys). Looking ahead, machine learning shows real potential for forecasting patient satisfaction outcomes. Implementing routine PROM collection in aesthetic practice makes sense on multiple fronts: better patient selection, benchmarking quality across surgeons, protecting against medicolegal concerns, and aligning with value-based healthcare models. We also discuss how AI and 3D imaging might reshape outcome assessment going forward.
