Abstract
BACKGROUND: Numerous techniques and materials are available for increasing the dorsal height and length of the nose. Microautologous fat transplantation (MAFT) may be an appropriate strategy for augmentation rhinoplasty. OBJECTIVES: The authors sought to determine the long-term results of MAFT with the so-called one-third maneuver in Asian patients who underwent augmentation rhinoplasty. METHODS: A total of 198 patients who underwent primary augmentation rhinoplasty with MAFT were evaluated in a retrospective study. Fat was harvested by liposuction and was processed and refined by centrifugation. Minute parcels of purified fat were transplanted to the nasal dorsum with a MAFT-Gun. Patient satisfaction was scored with a 5-point Likert scale, and aesthetic outcomes were validated with pre- and postoperative photographs. RESULTS: The mean age of the patients was 45.5 years. The mean operating time for MAFT was 25 minutes, and patients underwent 1-3 MAFT sessions. The mean volume of fat delivered per session was 3.4 mL (range, 2.0-5.5 mL). Patients received follow-up for an average of 19 months (range, 6-42 months). Overall, 125 of 198 patients (63.1%) indicated that they were satisfied with the results of 1-3 sessions of MAFT. There were no major complications. CONCLUSIONS: The results of this study support MAFT as an appropriate fat-transfer strategy for Asian patients undergoing primary augmentation rhinoplasty. LEVEL OF EVIDENCE 4: Therapeutic.
