自體脂肪補臉已成為臉部年輕化的好方法。在 2014 Jun;19(6):556-61.發表文章比較自體脂肪補臉用離心或簡單的過濾脂肪。這項研究比較1.離心2.簡單過濾和洗滌脂肪獲得的臨床效果比較。

作者對32位進行鼻唇溝脂肪移植2009至2011年前瞻性單盲分析。分配兩組隨機患者,一組(16例),離心脂肪後注射,另一組用簡單的過濾和洗滌的脂肪,以評估對脂肪移植存活率

客觀方法(根據鼻唇溝刻度),術後照片(1,6和12月)的評估。主觀的方法是從患者約滿意度和改善皮膚紋理的總體水平得到了自我評估,統計分析是由魏氏和Mann-Whitney檢驗的方式進行。

結果:第1組(3400轉離心1分鐘)之移植脂肪的存活率與第2組(簡單的過濾和洗滌脂肪)沒有顯著差異。

個人臨床心得: 雖然如此離心後的脂肪比較好補,是我比較喜歡採取的方式。

Comparison of fat maintenance in the face with centrifuge versus filtered and washed fat.

Abstract

BACKGROUND:

Autogenous fat injection of the face is a viable and lasting remedy for soft tissue loss and has become a mainstay in facial rejuvenation. Fat transfer as either a stand-alone technique or as an adjunct to other filler technique and lifting depending on patient needs. Although soft tissue augmentation with autologous fat transfer has been increasingly used by esthetic surgeon, but there is no agreement concerning the best way of processing the harvested fat before injection. This study compared the clinical results obtained using simple filtered and washed fat via metal sieve with those achieved by means of pure centrifuged fat.

MATERIALS AND METHODS:

A prospective single-blind analysis on 32 healthy patients undergoing nasolabial fold fat transplantation from 2009 to 2011 (simple sampling). Patients assigned in two groups randomly. The face of half (16 subjects) was injected with centrifuged, another half with simple filtered and washed fat to evaluate the effect of preparation methods on fat graft viability. Objective method was used to evaluate the results, involving the evaluation of postoperative photographs (in month 1, 6 and 12) by an esthetic surgeon (according to the nasolabial scale). Subjective method was a self-assessment obtained from patients about general level of satisfaction and improvement of skin texture, statistical analysis were performed by means of the Wilcoxon and Mann-Whitney test. Acquired data were analyzed using SPSS version 15 and a value of P > 0.05 was considered as significant.

RESULTS:

There was no significant difference in the survival of grafted fat between the Group 1 (fat-processing with centrifuge at 3400 rpm for 1-min) and Group 2 (washing the fat in the sieve).

CONCLUSION:

Our data suggest that the centrifuge of the fat does not enhance survival of grafted fat (P > 0.05).
