目的探讨自体颗粒脂肪注射移植充填矫治面部凹陷的临床应用。方法标记面部凹陷部位,估计需要填充的脂肪量,取臀部或大腿部为供区。在肿胀麻醉下,用20 m l注射器吸脂,吸管采用3.0 mm的钝头吸管,负压应控制在20 m l注射器内3～5 m l左右真空。抽取脂肪颗粒,无菌状况下将所获脂肪颗粒洗去血迹、破碎脂肪细胞和脂滴,反复漂洗,至漂洗液色清透明;静置、分层后取中层饱满的脂肪颗粒注射在面部凹陷部位。结果采用自体脂肪颗粒移植充填矫正面部凹陷26例,其中6例患者经过了3次注射充填;12例患者经过了2次注射充填;8例患者经过了1次注射充填,均获良好效果。结论利用自体脂肪移植充填矫治面部凹陷,创伤小、并发症低、手术效果明显,相对现有其他治疗方法,是一种较为理想的治疗方法。
Objective To investigate the clinical application of autologous fat injection in the treatment of facial depression. Method mark the facial depression location, estimated need to fill the amount of fat, take the buttocks or thigh for the area. Under tumescent anesthesia, liposuction was performed with a 20-ml syringe and a 3.0-mm blunt tip pipette was used. The negative pressure should be controlled to about 3 to 5 ml in a 20 ml syringe. Fat particles were taken, the fat particles were washed under sterile conditions to remove blood, broken fat cells and lipid droplets, repeatedly rinsed until the rinse liquid color clear and transparent; After standing, layered middle fat particles were injected into the facial depression Site. Results The autologous fat grafts were implanted in 26 cases of facial deformity correction. Among them, 6 cases were injected with 3 times, 12 cases with 2 injection and 8 cases with 1 injection. Conclusion Autologous fat transplantation for the treatment of facial denting, small trauma, low complication, the effect is obvious, compared with other existing treatment methods, is an ideal method of treatment.
