Background: Self-assessment provides valuable feedback in the life-long process of mastering rhinoplasty. This study presents a method to measure and evaluate data-based performance of a single surgeon using a web-based dashboard. Methods: In this prospective analytic cohort study, all patients referred to the senior author for functional-aesthetic (revision) rhinoplasty between April 2014 and September 2020 are included. Patients completed the Nasal Obstruction Symptom Evaluation (NOSE) scale, Utrecht Questionnaire (UQ), and visual analog scales before and after rhinoplasty. Questionnaire scores were exported to a customized web-based dashboard: the rhinoplasty health care monitor. Supported by real-time graphic output, this monitor automatically analyzes functional and aesthetic outcomes. Results: Of 603 referred patients, 363 were eligible for rhinoplasty. Mean NOSE scale scores decreased from 66.6 ± 23.5 to 23.2 ± 24.0 (p < 0.001), and mean UQ scores decreased from 12.2 ± 6.3 to 7.1 ± 3.9 (p < 0.001) 1 year after surgery. The rhinoplasty health care monitor visualizes numerous outcome parameters that help the surgeon to analyze results, identify learning needs, and detect trends in performance development. Conclusions: This automated outcome dashboard transparently measures individual surgeon performance. Gauging performance provides means to enhance surgical development and, consequently, patient satisfaction.
