A Cannula-Based Sequential Injection Protocol for Non-surgical Rhinoplasty in East Asian Patients.
Non‑surgical rhinoplasty is increasingly popular for nasal augmentation in East Asian patients.
In this dual‑center retrospective study, 528 East Asian patients (490 females, 38 males; mean age 27.7 years) underwent non‑surgical rhinoplasty between 2020 and 2024.
Three‑dimensional analysis of the 426 patients who received the full three-site protocol showed significant improvements from baseline in nasal length (+ 2.62 mm), tip projection (+ 3.69 mm), nasolabial angle (+ 5.7°), and nasofrontal angle (- 9.4°) (all p < 0.001).
No vascular complications occurred; 11 cases had transient erythema that resolved spontaneously or with conservative measures.
The sequential "tip‑dorsum‑glabella" injection protocol, featuring a refined cannula‑based technique for fibrous septal tip augmentation, was associated with a low complication rate and significant short‑term improvements in patient‑reported and anthropometric outcomes in this retrospective analysis, suggesting that it is a clinically feasible approach for non‑surgical rhinoplasty in East Asian patients.
