Guidelines for Optimal Patient Outcomes Using Calcium Hydroxylapatite for Jawline Contour

Calcium hydroxylapatite (CaHA(+); Radiesse(+) [Merz North America, Inc., Raleigh, NC]) is the first FDA-approved injectable filler for subdermal and/or supraperiosteal injection to improve moderate-to-severe loss of jawline contour. CaHA has been recognized in the past for its ability to provide contour and support overlying tissues and utilized for jawline augmentation well before this recent indication; however, with recent FDA approval of CaHA(+) for jawline contour improvement, it is important that clinicians are aware of best practices for patient selection, treatment planning and injection, as well as safety considerations and postprocedure care.

To provide guidance on best practices for patient assessment and on-label use of CaHA(+) for jawline rejuvenation and augmentation.

As part of a 2-h roundtable discussion, 5 clinicians with expertise in both the use of CaHA(+) and jawline treatment discussed patient selection, CaHA(+) injection technique, and important safety measures, with the purpose of developing guidance to support optimal clinical use.

The most common applications of CaHA(+) in the jawline are rejuvenation of the prejowl sulcus, recontouring the jawline, and providing definition to the gonial angle. Improving the gonial angle is of particular interest as it is a procedure sought by patients of all genders and ages. Variations in technique are discussed and case studies are presented.

Jawline augmentation is a procedure with wide-ranging appeal for a diverse array of patients. CaHA(+) is an ideal filler for jawline augmentation due to its rheologic properties (high G') and ability to achieve defined contours and angles. Appropriate injection technique permits effective treatment and outcomes associated with high patient satisfaction.
