Summary
Non-surgical rhinoplasty with hyaluronic acid (HA) fillers offers good results regardless of injector experience. However, more experienced injectors lead to higher patient satisfaction with HA fillers.
Area of Science:
- Aesthetic Medicine
- Dermatology
- Plastic Surgery
Background:
- Non-surgical rhinoplasty using hyaluronic acid (HA) fillers is a popular alternative to surgery.
- Concerns exist regarding adverse events, especially with less experienced practitioners.
Purpose of the Study:
- Evaluate outcomes of non-surgical rhinoplasty with HA based on injector experience.
- Investigate the influence of experience on aesthetic satisfaction, safety, product volume, and treatment duration.
Main Methods:
- Retrospective analysis of 59 patients and 53 injectors with varied experience.
- Collected data on HA volume, injector experience, aesthetic satisfaction (GAIS), and perceived results duration.
- Utilized Kruskal-Wallis tests, Spearman correlations, and regression analyses.
Main Results:
- Mean HA volume was 0.45 mL, with no significant difference across experience levels.
- Overall patient satisfaction (GAIS) was high, with significantly greater satisfaction reported with more experienced injectors.
- Perceived results duration was 6-9 months, unaffected by injector experience. No serious adverse events occurred.
Conclusions:
- Non-surgical rhinoplasty with HA can yield favorable outcomes irrespective of injector experience when using standardized techniques.
- Increased injector experience correlates with higher patient satisfaction but not with filler volume or duration of results.
