Microautologous Fat Transplantation for Primary Augmentation Rhinoplasty: Long-Term Monitoring of 198 Asian Patients

Abstract

BackgroundNumerous 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.ObjectivesThe authors sought to determine the long-term results of MAFT with the so-called one-third maneuver in Asian patients who underwent augmentation rhinoplasty.MethodsA 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.ResultsThe 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.ConclusionsThe results of this study support MAFT as an appropriate fat-transfer strategy for Asian patients undergoing primary augmentation rhinoplasty.Level of Evidence: 4 Therapeutic

Micro-autologous fat transplantation for rejuvenation of the dorsal surface of the aging hand

“…The clinical results obtained using MAFT have demonstrated the feasibility of this approach and the importance of controlling the fat parcel size in achieving favorable outcomes. [21][22][23][24][25][26][27] Specifically, the patent mechanism with accurate and consistent control 32 of the parcel volume is critical to avoid occasional dislodgement of larger parcels, which in turn could result in nodulation and skin irregularity after fat grafting.…”

“…[14][15][16][17][18][19] Lin et al proposed the concept of micro-autologous fat transplantation (MAFT) in 2006 and demonstrated the reliability of the technique in facial rejuvenation. [20][21][22][23][24][25][26][27] In this study, we clinically performed the MAFT technique for the rejuvenation of aging dorsal hand surfaces and determined the long-term results.…”

Commentary on: Microautologous Fat Transplantation for Primary Augmentation Rhinoplasty: Long-Term Monitoring of 198 Asian Patients

“…In the current paper, 5 where 198 patients had no complications whatsoever (which is to be congratulated), it would be interesting to know what precautions the authors took to avoid these complications. Were local blocks with lidocaine and adrenaline used to create local vasoconstriction?…”

“…5 The technique and rationale for using it is well described and it would be easy for any physician to understand how to use this device. Such patients are always receptive to exploring minimally invasive techniques since traditional surgical rhinoplasty using synthetic materials such as silicone have their fair share of unwanted side effects.…”

“…The paper 5 is laid out systematically but there is one significant omission which needs to be addressed: a discussion on the relevant anatomy of the nose, in particular its vasculature and how to avoid a serious complication of vascular occlusion and visual loss.…”
