摘要

Background

Non-surgical rhinoplasty using hyaluronic acid (HA) fillers has become an increasingly popular alternative to surgical approaches. However, concerns persist regarding adverse events, particularly when procedures are performed by less experienced injectors.

Objectives

This study aimed to evaluate perceived outcomes of non-surgical rhinoplasty with HA according to the injector’s clinical experience level, and to investigate whether experience influences aesthetic satisfaction, safety, product volume used, or perceived treatment duration.

Methods

This retrospective, single-center study analyzed 59 patients who underwent non-surgical rhinoplasty using HA, performed by 53 injectors with varying clinical experience levels in non-surgical rhinoplasty. Data were collected on age, BMI, volume of HA injected per nasal subunit, injector experience, aesthetic satisfaction using the Global Aesthetic Improvement Scale (GAIS), and perceived duration of results. Statistical analyses included Kruskal–Wallis tests, Spearman correlations, linear regression, and ordinal logistic regression.

Results

The mean total volume of HA injected per procedure was 0.45 (± 0.15) mL, with no significant differences across experience levels (p = 0.374). The overall median GAIS score was 1.0 (IQR: 1.0), indicating improvement, with significantly higher satisfaction among patients treated by more experienced injectors (p < 0.001). Perceived duration of results was 6–9 months with no significant differences by injector experience (p = 0.117). No serious or vascular adverse events were reported.

Conclusions

Non-surgical rhinoplasty with HA may provide favorable outcomes across injector experience levels when performed with a standardized technique and an appropriate product. Greater clinical experience correlated with higher patient satisfaction but not with filler volume or duration of effect.
