多隧道、多层次自体脂肪颗粒移植在矫治额颞部凹陷中的作用

Autologous fat granule graft of multiple tubes and layers in the correction of fronto-temporal depression

目的:探讨应用自体脂肪颗粒多隧道、多层次游离移植矫治额颞部凹陷的临床效果。方法:选取2003-08/2004-12中国医学科学院整形外科医院颅颌面外科门诊及住院患者,通过注射麻醉液预先估计填充量,受区皮下预处理形成多个隧道。以注射器吸取腹部脂肪颗粒,经纯化后,分皮下和肌肉内,超量30%注射充填额颞部凹陷。随访1年观察患者凹处陷脂肪颗粒移植效果。结果:24例患者均进入结果分析。患者额颞部凹陷处脂肪颗粒移植效果:术后未发现有感染、坏死及液化等症状。除6例进行二次注射外,其余均为一次性注射。充填后原凹陷部位丰满,局部无硬结,质感和外形好,与周围组织无界限。结论:自体脂肪颗粒移植矫治额颞部的凹陷,塑型容易,其形态质感与周围组织一致,无明显界限,且方法简便。

AIM： To explore the clinical effect on the fronto-temporal augmentation by the free transplantation of autologous fat granule of multiple tubes and layel＇s. METHODS： The outpatients and inpatients in the Department of Craniomaxillofacial Surgery, Plastic Surgery Hospital affiliated to Chinese Academy of Medical Sciences＆Peking Union Medical College between August 2003 and December 2004 were selected. The amount of soft-tissue defect was estimated by the volume of the injected local anaesthetic liquid. Many tubes were formed subcutaneously in the region to be augmented. Abdominal fat granule was aspirated with common syringe and then reinjected into those tubes and into or under the muscle of the fronto-temporal region after be concentrated. The volume was 30% over the estimation. The patients were followed up for 1 year. RESULTS： All the 24 patients were involved in the analysis of results. Effect of transplanted results of fat granules： No infection, necrosis, liquefaction and other symptoms were observed. Only 6 cased needed secondary injection, others were all corrected only by one time with no complication. With the follow-up from with 3 months to 1 year, all the cases were satisfying with external shape. CONCLUSION： The operating of injection grafting technique of the fat granule is a simple and ideal method for fronto-temporal augmentation.
