Background:
Nonsurgical chin augmentation using hyaluronic acid (HA) has become a common procedure in cosmetic practices. This is offered to patients that prefer a nonsurgical, temporary method to correcting underdeveloped or retruded chin and restoring the volume loss. This systematic review highlights the main HA injection technique and associated patient satisfaction and complications of chin augmentation to further guide practitioners.
Methods:
A systematic review was performed according to PRISMA guidelines. PubMed, Embase, and Web of Science were searched using the appropriate keywords. Data collected from each study included patient satisfaction and complications, in addition to injection protocol and technique.
Results:
A total of 1305 studies were found based on search criteria. After full-text screening for inclusion and exclusion criteria, 8 studies were included. A total of 917 patients underwent HA chin augmentation, with different injection protocols. Most patients were satisfied with the results, and there were only 2 relatively major complications reported. The most common adverse events were local responses at the injection sites (swelling, bruising, pain, redness, and itching). There were no reports of vascular complications.
Conclusions:
HA filler is an effective temporary method to correct chin retraction and absorption for chin augmentation, with a high degree of patient satisfaction and a low risk of severe complications.
