【Abstract】 Objective To evaluate the effect of autologous free fat particle grafting combined with bFGF to repairfacial depression. Methods From April 2004 to May 2006, 41 patients with facial depression were randomized into two groups (groups A and B). In group A, 12 cases were admitted from April 2004 to December 2004. There were 5 males and 7 females, aging 16-49 years (mean, 31 years). The pathological causes were congenital facial depression in 2 patients, hemifacial atrophy in 2, traumatic cicatrix in 5 and benign tumor removal in 3. The course of disease was 2-19 years. The concave regions were low (0.52 ± 0.13）cm compared to surrounding normal skin, concave area (16.0 ± 5.3）cm2. In group B, 29 cases were admitted from January 2005 to May 2006. There were 14 males and 15 females, aging 18-52 years (mean, 37 years). The pathological causes were: congenital facial depression in 3 patients, hemifacial atrophy in 4, traumatic cicatrix in 15 and benign tumor removal in 7. The course of disease was 2-20 years. The concave regions were low (0.58 ± 0.15）cm compared to surrounding normal skin, concave area (18.0 ± 6.2）cm2. Cases in group A were treated with pure autologous free fat particleinjection; cases in group B were treated with autologous free fat particle injection combined with bFGF(4 200 IU/10 mL). The cl inical outcome were comparatively analyzed between two groups after operation. Results The follow-up time was 6 to 24 months (mean, 12.5 months) in group A and 6 to 24 months (mean, 13 months) in group B. In group A, 6 patients achieved satisfactory cl inical effect after one injection of fat particle, the satisfactory rate of one therapy being 50%; other 6 cases were required reinjection of fat particle 6-12 months postoperatively, of which two-time injections in 3 cases, three-time injections in 3 cases. In group B, 24 patients achieved satisfactory cl inical effect after one injection of fat particle, the satisfactory rate of one therapy being 82.8%; only 5 cases were required reinjection one year postoperatively. There was statistically significant difference in the satisfactory rate of one injection between two groups (P lt; 0.05). Conclusion Autologous free fat particle grafting combined with bFGF to treat facial depression can acquire satisfactory cl inical effect, which is a safe and effective method.
【Abstract】 Objective To investigate the cl inical effect of transplanting by auto-fat granule injection for mastatrophy post suckl ing. Methods From March 2000 to June 2006, 73 patients(146 breasts ) with mastatrophy post suckl ing were treated by transplanting auto-fat granule. The mastatrophy occurred between ages 28 and 52 years with a median of 37 years post suckl ing. The breasts shrank and their elasticity decreased gradually within 2-10 years post suckl ing. The autofat granule was obtained by l iposuction with syringe from patient’s abdomen, waist, buttocks and thighs, etc. After repeated wash and purification, the auto-fat granule was transplanted into the interspace behind the breast by injection. The quantity of auto-fat granule was 50-100 mL in each side of breast per transplantation at 3-6 months intervals, and the whole course of treatment needed 2-6 transplantations. Results The incisions in all cases healed primarily postoperatively. In 73 cases, 65 were followed up from 6 months to 3 years post operation. All patients had a significant improvement in their breast size and shape postoperatively and their breasts were soft and natural in appearance and feel. All of them had more perfect arcuation ofphysique and body with strengthened self-confidence, rel ieved mood and improved qual ity of l ife. However, small indurations were found sporadically in 7 cases (10 breasts) within 2-7 months, and calcifications in 5 cases (8 breasts) within 9-14 months post the first operation. Conclusion The transplantation by auto-fat granule injection for mastatrophy post suckl ing is an effective and practical method. The surgical technique is well worth performing in cl inical practice.
