RESUMEN
Resumen Objetivo: Describir la evolución que presentaron los pacientes con la aplicación de injerto graso autólogo con plasma rico en plaquetas (IGAPRP) en defectos de espesor completo (DET). Método: Durante el periodo del 15 de abril al 30 de septiembre de 2021 se analizaron los DET de pacientes que recibieron IGAPRP. Resultados: Se realizaron de 3 a 4 procedimientos de aplicación de IGAPRP para su integración con un tiempo promedio de estancia hospitalaria de 19.6±0.5 días. El tamaño de la lesión fue de 17.5 a 280 cm2 (95.1±81.6 cm2, profundidad de 1.1±1.1 cm). Volumen de grasa injertada en los DET fue de 14.7±7.9 ml. No se identificaron casos con infección. La comparación de la dimensión de los defectos a través de los procedimientos reveló una diferencia de 95.13 cm2 con hallazgos estadísticamente significativos (p<0.001). Limitaciones del estudio: La población de estudio limitada a solo 6 pacientes no nos permite sacar conclusiones significativas con respecto al efecto del tratamiento. A pesar hubo diferencias significativas en el volumen y área de los DET. Se requiere un estudio multicéntrico para evaluar completamente la eficacia de estos tratamientos en pacientes con DET. Valor: El uso de IGAPRP podría disminuir secuelas y complicaciones del uso de colgajos para la reconstrucción de DET. Conclusiones: La aplicación de IGAPRP demostró ser una opción eficaz y segura para la granulación de DET en nuestros pacientes para su posterior cobertura con un injerto cutáneo de espesor parcial.
Abstract: Objective: To describe the evolution of patients with the application of autologous fat grafting with platelet-rich plasma (IGAPRP) in full-thickness defects (TED). Method: During the period from April 15, 2021 to September 30, 2021, the TEDs of patients who received IGAPRP were analyzed. Results: 3 to 4 IGAPRP application procedures were performed for its integration with an average hospital stay of 19.6±0.5 days. Lesion size ranged from 17.5 to 280 cm2 (95.1±81.6 cm2, Depth 1.1±1.1 cm). Volume of grafted fat in the TEDs was 14.7±7.9 ml. No cases of infection were identified. The comparison of the dimensions of the defects through the procedures revealed a difference of 95.13 cm2 with statistically significant findings (p<0.001). Study limitations: The study population limited to only 6 patients does not allow us to draw significant conclusions regarding the effect of treatment. Despite there were significant differences in the volume and area of ??the TEDs. A multicenter study is required to fully evaluate the efficacy of these treatments in patients with TED. Value: The use of IGAPRP could reduce sequelae and complications of the use of flaps for TED reconstruction. Conclusions: The application of IGAPRP proved to be an effective and safe option for TED granulation in our patients for subsequent coverage with a split-thickness skin graft.
RESUMEN
Introducción: El aumento de glúteos tiene como objetivo lograr una apariencia y contorno más joven; así como crear la proporción ideal entre cintura y cadera. Esto se puede lograr mediante la lipoinyección, aunque en este caso existen controversias en cuanto a la viabilidad del tejido injertado y la supervivencia de la grasa. Objetivo: Determinar el porcentaje de supervivencia del injerto de grasa autóloga y su relación con el volumen inyectado en pacientes sometidas a lipotransferencia glútea. Métodos: Se realizó un estudio observacional, descriptivo, de corte longitudinal y prospectivo con una muestra de 44 pacientes sometidas a lipotransferencia glútea en el Servicio de Cirugía Plástica del Hospital Docente Clínico Quirúrgico Dr. Miguel Enríquez en el período comprendido entre marzo de 2018 y junio de 2021. Resultados: El estudio evidencia que, mediante ultrasonido y fórmulas, el volumen promedio y la altura de la de grasa en los glúteos se duplica en el posoperatorio mediato y disminuye en el posoperatorio tardío sin llegar a los valores del preoperatorio. Además, se estableció que cerca de la media del volumen de grasa autóloga injertada en los glúteos sobrevive de manera definitiva en el posoperatorio tardío. Además, quedó establecido que la relación entre el volumen infiltrado y la supervivencia del injerto de grasa autóloga es inversamente proporcional: mientras mayor es el volumen, menor es su supervivencia. Conclusiones: Solo la mitad del volumen de grasa autóloga injertada en los glúteos sobrevive de manera definitiva, y la supervivencia de la grasa es inversamente proporcional al volumen infiltrado(AU)
Introduction: Buttock augmentation aims to achieve a more youthful appearance and contour; as well as creating the ideal proportion between waist and hips. This can be achieved by lipoinjection, although in this case there are controversies regarding the viability of the injected tissue and the survival of the fat. Objective: To determine the percentage of autologous fat graft survival and its relationship with the injected volume in patients undergoing gluteal fat transfer. Methods: An observational, descriptive, longitudinal and prospective study was carried out, with a sample of 44 patients undergoing gluteal lipotransfer, in the plastic surgery service of the Dr. Miguel Enriquez Clinical Surgical Teaching Hospital, in the intermediate period between March 2018 to June 2021. Results: The study shows that through ultrasound and formulas, the average volume and height of fat in the buttocks doubles in the immediate postoperative period, decreasing in the late postoperative period, without reaching preoperative values. Furthermore, it's established that about the mean volume of autologous fat grafted to the buttocks survives definitively in the late postoperative period. In addition, it was established that the relationship between the infiltrated volume and the survival of the autologous fat graft is inversely proportional, the greater the volume, the less its survival. Conclusions: Only half of the volume of autologous fat injected into the buttocks survives definitively, and the survival of the fat is inversely proportional to the volume injected(AU)

Objective:To explore the effect of facial filling with autologous fat particles on the facial contour remodeling of patients with facial rejuvenation needs and its influence on the facial skin indicators of patients.Methods:From February 2019 to February 2020, 225 female patients, aged 25-52 years, with an average age of (42.5±5.2) years, received facial rejuvenation treatment in Zhengzhou Mylai Medical Beauty Hospital. They were divided into observation group (PPDO serrated line lifting combined with autologous fat granule filling), control group 1 (PPDO serrated line lifting alone) and control group 2 (simple autologous fat granule filling alone), with 75 cases in each group. After 6 months of follow-up, facial skin indexes, contour remodeling effect and adverse reactions after treatment were compared among the three groups.Results:At the last follow-up, the facial skin elasticity and moisture scores of the observation group (63.45±10.11, 56.71±9.38) were significantly higher than those of control group 1 (51.11±9.23, 43.69±7.65) and control group 2 (52.35±9.51, 42.47±7.53). The facial spots and lipid scores (41.31±7.24, 42.18±7.46) were significantly lower than those in control group 1 (48.67±9.15, 53.49±9.45) and control group 2 (48.26±9.21, 53.55±9.53) ( F=37.39, 68.98, 17.42, 40.91, P<0.001). At the last follow-up, the lower surface width of observation group (11.35±0.63) was lower than that of control group 1 (12.21±0.85) and control group 2 (12.38±0.65). The contour ratio of the lower part of the face (0.63±0.17) was higher than that of control group 1 (0.56±0.15) and control group 2 (0.57±0.15) ( F=44.49, 4.36, P<0.05). The change level of the ratio of lower facial area (0.12±0.03) was higher than that of control group 1 (0.07±0.02) and control group 2 (0.08±0.04) ( F=54.31, P<0.001). Conclusions:For patients who need facial rejuvenation treatment, the use of autologous fat granule facial filling therapy has good clinical effects, which can significantly improve the patient's facial skin elasticity, moisture, spots, and oil. The patient's facial contour reshaping effect is better, and the aesthetic score is significantly improved, and does not increase the risk of adverse reactions.
RESUMEN
Objective:To investigate the causes of buccal masses after temporal autologous fat grafting, and to summarize the therapeutic methods to avoid medical disputes.Methods:Ten female patients (25-40 years; mean age, 33.1±7.5 years) with buccal mass complication after temporal autologous fat grafting were retrospectively analyzed, and statistics was done on their fat injection history, postoperative buccal mass symptom onset time, intraoperative mass conditions, postoperative pathological and fluid bacterial culture results, and postoperative recovery.Results:The unilateral temporal fat injection volume was 15-30 ml, and the buccal masses occurred 1-6 months after temporal autologous fat grafting. Lipoid masses were found in the buccal space during the operation, and some of them contained liquid. The postoperative pathological results indicated local necrosis in fibrotic adipose tissues. All the fluid bacteria cultures were negative, only one showed positive culture of acid-fast bacilli. 6-12 months postoperative follow-up visit was performed, and 9 patients recovered and 1 patient recovered after re-operation.Conclusions:The overfilled fat and liquefied necrotic fat after temporal fat grafting may move down to buccal space to form buccal masses, which should be treated by operation early to achieve a good prognosis.

RESUMEN
Objective:To compare the clinical efficacy of autologous fat injection and conjunctival pedicled orbital septal fat grafting for infraorbital margin depression in young people.Methods:Fourty young patients with lower eyelid pouch and infraorbital margin depression with age of 20 to 40 years and average age of 30.6 yaers in the First Affiliated Hospital of Nanchang University from September 2017 to September 2019 were enrolled. According to the surgical method, all patients were divided into 2 groups with 20 cases each. Group 1 underwent transconjunctival orbital septum fat reset. Group 2 underwent various autologous fat injection after proper amount of orbital septal fat being removed, including structural fat, fine-particle fat and nano-fat, performed in different parts and layers. The tear trough rating scale (TTRS) scores and patients＇ satisfaction at 1 year after operation between 2 groups were compared.Results:Compared with the preoperative TTRS scores, the differences in scores at 6 months and 1 year after surgery were statistically significant ( P<0.01). The scores between two groups were compared at 6 months and 1 year respectively after the operation, and the difference were both statistically significant ( P<0.01). 6 months after the operation, the TTRS scores including four items were carefully compared between the two groups. It showed that the reduction of tear groove depth ( P<0.05), pigmentation ( P<0.01) and wrinkle ( P<0.01) in group 2 were more obvious than those in group 1. The percentage of satisfaction in group 2 (95%) was higher than that in the group 1 (70%), and the difference was statistically significant ( P<0.01). Conclusions:For infraorbital margin depression of young people, after proper amount of orbital septal fat being removed, various free fats graft injection into different parts and layers could obtain better treatment results, reducing not only the depth of the tear groove, but also periorbital pigmentation and fine wrinkles.
RESUMEN
Objective:To observe the application and clinical effect of stromal vascular fraction gel (SVF-gel) in local rhinoplasty.Methods:A total of 84 patients with mild nasal root and low bridge were divided into observation group and control group. In the observation group, liposuction with SVF gel extraction plus injection rhinoplasty was carried out; in the control group, liposuction plus injection rhinoplasty was carried out according to the height change of nasal root and bridge, the change of nasal frontal angle, the occurrence of complications and the satisfaction of patients after operation.Results:The 84 patients were followed up for 2 weeks to 24 months. The height of nasal root and bridge increased significantly and the lines were more harmonious. The absorption of the observation group was much lower than that of control group. Except 3 patients in the observation group and 8 patients in the control group, there were different degrees of absorption within 6 months after operation. All patients did not have complications such as fat liquefaction, necrosis, induration and infection in the injection area. Three patients in the observation group were satisfied with the results after reinjection, and one patient in the control group was satisfied with the results after reinjection, three patients were not satisfied with the results, and four patients were satisfied with the prosthesis augmentation rhinoplasty. In the observation group, there were 37 cases of excellent satisfaction, 5 cases of good satisfaction, and the overall satisfaction was 100%; in the control group, there were 20 cases of excellent satisfaction, 15 cases of good satisfaction, 7 cases of bad satisfaction, and the satisfaction was 83.3%. The former was better than the latter.Conclusions:In view of superiorities such as lower complications with long-lasting effect, high fat survival rate and high satisfaction in local augmentation rhinoplasty, SVF-gel injection is especially suitable for patients who cannot accept autologous bone, prosthesis and allograft tissue filler for augmentation rhinoplasty.
RESUMEN
@#Autologous fat transplantation in the treatment of velopharyngeal insufficiency has the advantages of good histocompatibility, small local trauma, few complications, reversible operation and simple postoperative nursing, which can effectively increase the velopharyngeal closure area. If the clinical effect is poor, other surgical methods can be used at any time for replacement. Although there are many advantages in the treatment of velopharyngeal insufficiency with autologous fat transplantation, there are still some problems in the selection of indication, donor site, injection dose, recipient site, follow-up evaluation, complications and prevention and treatment. Current research shows that autologous fat transplantation is mainly used in patients with mild or moderate velopharyngeal insufficiency, but with the improvement of fat acquisition and treatment techniques, the indications for autologous fat transplantation continue to expand, and autologous fat transplantation combined with palatoplasty or pharyngoplasty has been proposed for the treatment of severe velopharyngeal insufficiency. However, there are complications, such as fat absorption and obstructive sleep apnea syndrome. In addition, the application of autologous fat transplantation in severe VPI patients and how to improve the long-term stability of autologous fat transplantation need further study.
RESUMEN
Objective To evaluate the effect and mechanism of cysteine rich protein 61, namely CCN family member 1(CCN1) on the survival of adipose tissues in rats after autologous fat grafting. Methods At 1 week after the establishment of autologous fat grafting rat models, all animals were randomly divided into the CCN1 group (n=20) and control group (n=20). The survival of fat grafts, the morphology of fat graft tissues, the proportion of active adipocytes and the number of new blood vessels of rats were statistically compared between two groups. The levels of differential expressed messenger ribonucleic acid (mRNA) in the fat graft tissues of rats were compared between two groups by high-throughput sequencing and subsequently subject to cluster analysis. The expression levels of related proinflammatory cytokines of fat graft tissues of rats were statistically compared between two groups. Results The weight retention rate of adipose tissues in the CCN1 group was significantly higher than that in the control group (P < 0.05). In the CCN1 group, the integrity of adipocytes was considerably higher, the degree of vesiculation and vacuolation, the degree of inflammatory cell aggregation and the degree of fibrosis were significantly lower than those in the control group (all P < 0.000 1). Immunofluorescence staining demonstrated that the proportion of active adipocytes with uniform morphology was higher in the CCN1 group, whereas the proportion of active adipocytes was lower and the cells were observed in different sizes accompanied by vesiculation in the control group. Compared with the control group, the quantity of new blood vessels was significantly higher, and the expression levels of platelet derived growth factor (PDGF) and fibroblast growth factor (FGF) mRNA were remarkably higher in the CCN1 group (all P < 0.05). High-throughput sequencing analysis showed that the data at the transcriptome levels significantly differed between two groups. In the CCN1 group, the gene expression levels of cell surface markers, inflammatory cytokines and chemokines related to M1 macrophages tended to decline. Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) revealed that the mRNA expression levels of interleukin (IL)-8, IL-1 and Toll-like receptor (TLR) 2 in the CCN1 group were significantly lower than those in the control group (P < 0.01-0.05). Conclusions During autologous fat grafting, supplement of exogenous CCN1 may effectively promote the neovascularization of adipose tissues and improve the survival rate of fat graft probably by mediating the transformation of macrophages into M2 phenotype via down-regulating the TLR2 expression level.

RESUMEN
Background@#Autologous fat grafting has gained popularity in breast augmentation. Various methods can be used to estimate the volume retention rate. This systematic review aimed to establish whether the type of method used for measuring breast volume is a factor that influences the reported volume retention rate.@*Methods@#Studies were identified using the electronic databases PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science from inception of the database up to February 2019. Articles describing autologous fat grafting for breast augmentation were selected based on pre-determined inclusion and exclusion criteria. The characteristics of the included studies were summarized, and the reported volume retention rate from the studies was compared. A quality assessment of all included articles was performed using the methodological index for non-randomized studies criteria.@*Results@#A total of 618 articles were identified, of which 12 studies, with a total of 1337 cases, were eligible. The retention rate of injected adipose tissue varied when the method of fat grafting and volume analysis used were both the same, as well as when the method of fat grafting was the same but the method of volumetric evaluation used was different.@*Conclusions@#Currently, the tools available for estimating the volume retention rate come with limitations. In order to objectively evaluate the percentage of graft retention, a standard protocol that applies to the different methods should be established in the future.
RESUMEN
Objective@#To investigate the effect of adding glutathion(GSH) to tumescent solution on autologous fat graft survival.@*Methods@#14 male and female New Zealand rabbits were divided into experimental group and control group randomly, 7 in each group. Experimental group: The donor areas of the rabbits were injected with 3 ml of tumescent solution with GSH. Control group: The donor areas of the rabbits were injected with 3 ml regular tumescent solution. DCFH-DA probe was used for fluorescent staining of harvested fat cells. Then stained fat cells were measured for the intracellular reactive oxygen species(ROS)content by fluorescence microplate. The grafts were harvested at 3 months after transplantation and assessed by general observation, volume measurement, wet weight measurement, HE staining for the number of fat cells, and CD34 immunohistochemical staining for the measurement of micro-vascular density. T test was performed by using SPSS 24.0.@*Results@#The intracellular ROS content of harvested fat cells in experimental group was lower than that in control group, and the difference was statistically significant (P<0.05). At 3 months after transplantation, the wet weight of fat grafts in experimental group was (1133.21±87.97) mg and that in control group was (718.79±79.27) mg. The volume of fat grafts in experimental group was (1.00±0.04) ml and that in control group was (0.59±0.03) ml. The number of fat cells in experimental group was (746.6±15.7)/10 high magnification vision and that in control group was (350.1±32.4)/10 high magnification vision. The density in group experimental was (8.1±2.0)/high magnification vision and that in control group was (6.7±2.4)/high magnification vision. The grafts′ volume, wet weight, and the number of fat cells in experimental group were higher than those in control group, and the differences were statistically significant (P<0.05). The difference of micro-vascular density between experimental group and control group had no statistical significance (P>0.05).@*Conclusions@#The addition of GSH to tumescent solution optimizes the process of autologous fat harvest, thereby improving the survival of fat graft.
RESUMEN
Cerebral artery embolism is a rare but serious complication of facial plastic surgery. This paper reports a case of severe total cerebral arterial fat embolism caused by facial autologous fat injection. The patient past away after 40 hours of treatment. The cause of this total cerebral artery embolism patient was analyzed by tracing relevant medical history and cephalic CTA examination. By studying this case, we hope to reduce the occurrence of similar situations in the future.
RESUMEN
Scars formed by various injuries can affect the appearance and psychology of patients. Therefore, more and more people pay attention to the prevention and treatment of scar. With the development of the autologous fat grafting, it has been gradually applied to the prevention and treatment of scar. At present, it has been confirmed by scholars that the autologous fat grafting could be an effective method to prevent and treat scar from basic research and clinical practice. At the same time, the deficiency of autologous fat grafting in the prevention and treatment of scar was also pointed out. This paper reviews the application, mechanism, and deficiency of autologous fat grafting in scar prevention and treatment.
RESUMEN
Since the autologous fat transplantation was reported by a German surgeon, Gustav Neuber, in 1893, the technical method of autologous fat transplantation, the transplantation concepts and application range have undergone tremendous changes and progress. In recent years, with the advanced research on adipose derived stem cells (ADSCs), the application field of autologous fat has been widespread. From initially used for soft tissue filling, it gradually expanded to orthopedic surgery, reconstructive surgery and cosmetic surgery, such as treatment of scar, skin and tendon adhesion, Renault syndrome, breast enhancement, facial rejuvenation and body shaping. The Nanofat transplantation technology originated from autologous fat transplantation, and it is not an exact nanotechnology for the technology itself. However, due to its remarkable effect on local skin rejuvenation, the Nanofat transplantation has become one of the hot issues in orthopedics in recent years.
RESUMEN
Objective To measure the change of facial volume maintenance rate after autologous fat grafted for repaired progressive facial hemiatrophy by using three-dimensional digital technology.Methods 3D scanner was used to acquire facial data in 10 patients with progressive facial hemiatrophy before operation;Mimics 17.0 software was used to reconstruce patients' facial 3D model and to calculate the volume of facial tissue defect;autologous fat was grafted to repair facial deformity.The facial volume maintenance rate was calculated in all the patients 3 months and 6 months after operation.Results We had performed facial 3D data acquisition and facial repaired with autologus fat grafted in 10 patients;patients' facial morphology was improved.The mean facial volume maintenance rate was (35.80±3.44)％ in 3 months and (27.82±3.80)％ 6 months after surgery.Conclusions The mean facial volume maintenance rate in postoperative 3 months is inferior to that in 6 months in single autologous fat grafted for repairing progressive facial hemiatrophy.
