Revision Rhinoplasty After Non-Surgical Filler in East Asian Patients: A Safe and Effective Surgical Approach.

[INTRODUCTION] Recent advancements in non-surgical cosmetic technologies have increased their popularity for facial rejuvenation, particularly non-surgical rhinoplasty in the Asian region. However, variability in injection techniques, unknown injectable materials, and off-label use have led to complications, often referred to nasal "disasters," which complicate subsequent surgical repairs. Thus, safe and effective treatment strategies for nasal repair following non-surgical rhinoplasty are urgently needed.

[MATERIALS AND METHODS] This study systematically reviewed patients who underwent surgical revision rhinoplasty in East Asia from June 2018 to January 2024. During a follow-up period of at least one year, postoperative photographs were analyzed, and patients were re-evaluated for symmetry, nose shape, and contour.

[RESULTS] Significant changes were observed in the heights of the N, P, and T points, with notable increases in the T and P points. The length of the NT line increased, postoperative ROE scores improved, and the median VAS score was 2, indicating enhanced patient satisfaction.

[CONCLUSION] Rhinoplasty revision surgery that combines complete injection removal, costal cartilage transplantation, a nasal septum 'X' framework, rectus abdominis fascia modification of the nasal dorsum, and expanded polytetrafluoroethylene (ePTFE) to elevate the nasal dorsum can achieve good, safe, and satisfactory results for patients who have undergone non-surgical filler rhinoplasty.
