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

Summary

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.
