Restoring jawline contour with calcium hydroxylapatite: A prospective, observational study

BACKGROUND: Jawline reshaping by replacing volume has become an indispensable component of modern facial rejuvenation. AIM: To evaluate calcium hydroxylapatite (CaHA) for the treatment of an aging jawline in a routine setting. METHODS: Five investigators enrolled 35 subjects requesting jawline rejuvenation with CaHA. Injections were performed according to investigators usual practice. Baseline and post-treatment scores were evaluated using Merz Aesthetics Scales®. Follow-up visits took place at Day 30 (Day 60 for those with touch-up at Day 30), 180, and 360. Physician and patient satisfaction, esthetic impact of treatment, and adverse events were recorded. RESULTS: Improvements in jawline contour compared with baseline were statistically significant at each visit, with scores of 2.42 (moderate to severe sagging) at baseline, 1.02 (mild) at Day 30/60 (P≤.0001), 1.11 at Day 180 (P≤.0001), and 1.45 at Day 360 (P=.0015). Statistically significant improvements in marionette line scores were also observed. Investigators rated results as "improved" to "very much improved" in all subjects up to Day 180, and in 81% of subjects at Day 360. Satisfaction with treatment was very high. Adverse events were mostly mild and related to either the procedure or injection technique. CONCLUSION: CaHA is a very effective agent for restoring jawline contour in routine practice and is associated with high levels of physician and patient satisfaction.
