Plastic Surgery
Facial Plastic Surgery
Aesthetic Surgery

Background:

Chin augmentation is a popular procedure for enhancing facial aesthetics.
Various surgical techniques exist to address microgenia (small chin).
This study systematically reviews outcomes and complications of different chin augmentation methods.

Approach:

A systematic literature review was conducted across major biomedical databases (MEDLINE, PubMed, PMC, CENTRAL).
Techniques were classified, and their associated outcomes and complications were tabulated and analyzed.
54 studies (1977-2020) involving 4897 patients were included.

Key Points:

Six main techniques identified: implants, osteotomy, autologous grafts, fillers, local tissue rearrangements, and combined approaches.
All techniques yielded satisfactory cosmetic outcomes.
Complication rates: 15.7% for implants and 19.7% for osteotomy, with transient mental nerve injuries noted in 2.4% and 16.4%, respectively.

Conclusions:

All chin augmentation techniques achieve good outcomes and high patient satisfaction.
Comprehensive knowledge of each procedure is crucial for minimizing specific complications.
Careful technique selection and execution are necessary to avoid nerve injuries and aesthetic discrepancies.
