Nonsurgical reshaping of the nose, chin, and jawline: A retrospective analysis using experience-based eligibility criteria.

Abstract

Nonsurgical reshaping of the nose, chin, and jawline with hyaluronic acid fillers is becoming increasingly popular. Appropriate patient selection is essential. To assess the safety and efficacy of nonsurgical treatment of these facial areas using experience-based eligibility criteria and injection of the high G' filler, VYC-25L. This was a retrospective analysis of patients undergoing aesthetic improvement of the nose, chin, and/or jawline with VYC-25L, selected based on detailed criteria derived from extensive experience and imaging assessments. In a subgroup of subjects, high-resolution 3D imaging was used to assess nasal angles, nasal hump height, and chin projection. A total of 135 patients were included (n=106 females; mean age, 43.4±14.3years; n=44 nose treatment only, n=24 chin/jawline only, n=67 both). Mean treatment volume was 3.3±2.0ml. In total, 111 individuals (82.2%) were injected in the nose (mean volume: 0.9±0.2ml) and 91 (67.4%) in the chin/jawline (mean volume: 3.8±0.8ml). Most complications were injection site-related (bruising, n=27 [20.0%]; pain, n=1 [0.7%]). One patient (0.7%) experienced lip herpes, successfully managed with antiviral therapy. Thirty-two individuals underwent 3D imaging, which showed substantial mean changes from baseline in nasofrontal angle (3.5±1.6 degrees), nasofacial angle (2.2±0.8 degrees), and nasolabial angle (3.9±2.6 degrees); decreases in nasal hump height (1.7±0.9mm); and increased chin projection (2.7±1.5mm). Nonsurgical reshaping of the nose, chin, and jawline was safe and effective using experience-based eligibility criteria and VYC-25L.
