Objective. To evaluate the effectiveness of fat autografts for cervicomental rejuvenation procedures and chin augmentation.

Material and methods. The study included 70 male and female patients aged 35-65 years with age-related changes in the lower third of the face, localized fat deposits in cervicomental area and insufficient chin projection between 2020 and 2024. All patients were divided into three groups: the 1st group (n=30) — medial platysmaplasty and chin augmentation with subplatysmal fat autograft; the 2nd group (n=15) — removal of Bichat’s fat and chin augmentation with fat autograft using Bichat’s fat pad; the 3rd group (n=25) — medial platysmaplasty and chin contouring with lipofilling.

Results. Patients with various age-related changes in the lower third of the face and insufficient chin projection underwent cervicomental rejuvenation and chin augmentation. In case of chin augmentation with subplatysmal fat autograft, chin prominence increased by 0.6±0.2 cm after 3 months, 0.5±0.3 cm after 6 months and 0.4±0.2 cm after 12 months. In chin augmentation using Bichat’s fat pad autograft, chin projection increased by 0.5±0.2, 0.4±0.2 and 0.3±0.4 cm, respectively. In chin contouring with lipofilling, chin projection increased by 0.6±0.4, 0.4±0.2 and 0.2±0.1 cm, respectively. In the 1st group, 2 (3%) patients had uneven chin contours. There were no infectious-inflammatory complications.

Conclusion. Autologous fat injections (lipofilling and fat autografts) are preferable for chin augmentation. Augmentation with subplatysmal fat autografts is a minimally invasive, safe, predictable, and long-term method for chin augmentation.
