| Summary: | Background:. Contemporary periorbital rejuvenation is undergoing a paradigm shift to an approach that prioritizes volume preservation and/or augmentation. However, the technical difficulties of using traditional fat grafting techniques in this area and the distinct ethnic features make periorbital rejuvenation in Asians especially challenging. Here, the authors present their approach to enhance the periorbita and outcomes.
Methods:. A retrospective chart review was performed for 33 consecutive patients who underwent microautologous fat transplantation (MAFT) to the periorbita using the MAFT gun device combined with excisional blepharoplasty. Additionally, preoperative and postoperative photographs were analyzed by external evaluators to grade the aesthetic outcomes and fat resorption rates.
Results:. Three months after surgery, patients looked on average 5.4 ± 3.4 years younger, and the aesthetic result was graded 7.4 ± 2 in a one-to-ten scale. The fat resorption rate was 19.6% ± 3.5% at 3 months and 32.2% ± 3.9% after 12 months (range: 12–24 months; P = 0.007). The overall morbidity rate was 12% (4 patients), including 1 visible lump (3%), an overcorrection case (3%) in the lower eyelid, and 2 palpable lumps in the upper eyelid (6%) which were not visible. One case of lower eyelid hollowness required secondary fat grafting.
Conclusions:. Traditional blepharoplasty procedures can be combined with fat grafting techniques to address volume loss and tissue descend while keeping ethnic identity. A fat injection device like the MAFT gun is safe and effective and provides long-term predictable outcomes for fat grafting around the periorbital thin skin.
