Comparison of clinical efficacy between autologous fat injection and orbital septum fat reset for infraorbital margin depression in young people / 中华医学美学美容杂志

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.

Periorbital Lipogranuloma after Facial Autologous Fat Injection and Its Treatment Outcomes

PURPOSE: To investigate periorbital lipogranuloma cases that developed after autologous fat injection and to determine various treatment outcomes from these cases. METHODS: This retrospective study involved 27 patients who presented with periocular mass (final diagnosis of lipogranuloma) and had history of facial autologous fat injection. The collected data included information on patient sex, age, clinical presentation, number and site of fat injections, interval between injections, duration from injection to symptom onset, fat harvesting site, use of cryopreservation, and treatment outcome. RESULTS: The most common presenting symptom was palpable mass (92.6%), followed by blepharoptosis and eyelid edema. The mean time from injection to symptom onset was 13.6 +/- 29.2 months (range, 2 to 153 months). Patients were managed by intralesional triamcinolone injection (six patients) and surgical excision (three patients); 18 patients were followed without treatment. Among the six patients who underwent intralesional triamcinolone injection, five showed complete resolution, and one showed partial resolution. Among the 18 patients who were followed without management, three showed spontaneous resolution over a 5-month follow-up period. CONCLUSIONS: Lipogranuloma can develop in the eyelid after autologous fat injection into the face. Both surgical excision and intralesional triamcinolone injection yield relatively good outcomes. Simple observation can be a good option because spontaneous resolution can occur in a subset of patients.

Segurança oncológica no uso de células tronco de origem adiposa e lipofilling na reconstrução mamária após câncer / Oncological safety in the use of stem cells from adipose origin and lipofilling in breast reconstruction after cancer

Lipofilling ou enxerto de gordura é uma técnica muito utilizada para corrigir defeitos em qualquer região do corpo humano. O objetivo deste estudo foi analisar a segurança desta técnica para corrigir defeitos de reconstruções mamárias após câncer de mama. Foram analisados 158 pacientes que receberam 194 procedimentos de enxerto de gordura, segundo a técnica de Coleman e realizados por um único cirurgião (MR). 98% das pacientes desta série tinham cirurgia oncológica mamária precedente: conservadora ou mastectomia com reconstrução. A única complicação pós-operatória encontrada nesta série foi a liponecrose associada à mastite em sete casos (3.6%), todos tratados com terapia antibiótica e curativos diários. Nos pacientes com precedente de cirurgia conservadora e tratados com enxerto de gordura, somente quatro (5.9%) apresentaram pequenas alterações na mamografia, simulando alterações benignas. Conclusão: O enxerto gorduroso pode ser uma boa solução para reparar defeitos após reconstrução em pacientes tratados de câncer de mama e pode reduzir indicações de cirurgias maiores, como reconstruções com retalhos miocutâneos. A incidência de complicações pósoperatórias é muito baixa e não ocorrem alterações significativas nas mamografias de seguimento oncológico...

Fat grafting is largely used to correct soft-tissue defects in any region of the human body. This study analysed its safety when the technique is used to correct defects after breast cancer reconstruction. A total of 158 patients who underwent 194 breast fat grafting procedures were analysed. Almost all patients (98%) had a personal history of breast cancer treated with conservative surgery or mastectomy followed by breast reconstruction. In all cases, fat grafting was performed according to the Coleman’s technique by a single surgeon. Immediate complications included liponecrosis and infection in seven cases (3.6%) that required only daily dressings and oral antibiotics administration. In cases of fat grafting after conservative surgery, only four patients (5,9%) showed minor alterations in the postoperative mammograms, consisting of the appearance of benign images. Breast fat grafting can be a good solution to repair defects after breast-cancer treatment and reconstruction, and can reduce the indication for more extensive surgeries such as myocutaneous flaps. Postoperative complication rates are very low and there is little alteration in the follow-up mammograms...

Magnetic Resonance Findings in Two Episodes of Repeated Cerebral Fat Embolisms in a Patient with Autologous Fat Injection into the Face

We report magnetic resonance image (MRI) and magnetic resonance spectroscopy (MRS) findings in a patient of cerebral fat embolism (CFE) occurred in a 26-year-old woman after an autologous fat injection into the face. After initial neurologic symptom onset, MRI and MRS data were obtained two times to investigate repeated CFE. We obtained the MRS data in the two different time intervals and two different echo times to compare the lesions with normal brain parenchyma. The results of MRS data showed that a decrease in N-acetyl-aspartate, an increase in lactate and a very high early peak of free lipids between 0.9 and 1.4 ppm were obtained at the acute infarcted lesion as compared with normal brain parenchyma. In addition, these findings were more clearly detected on short echo time spectrum rather than long spectrum. A close relationship between the clinical manifestations and MRI and MRS findings of the brain can helpful to distinguish CFE with other conditions and to evaluate the cause materials of infarctions rather than conventional MRI or diffusion-weighted imaging.

Nasolacrimal Duct Obstruction Following Midfacial Autologous Fat Injection / 대한이비인후과학회지

Epiphora is usually caused by nasolacrimal duct obstruction. The nasolacrimal duct obstruction is related with facial trauma, other nasal or paranasal sinus diseases, or recurrent dacryocystitis. We describe a case of iatrogenic nasolacrimal duct obstruction that occurred secondary to midfacial autologous fat injection. In our case, mal positioned fat tissue was detected on the dacryocystogram to be present in the lacrimal sac and the nasolacrimal duct. They were safely removed during dacryocystorhinostomy.

The Combined Effect of Autologous Fat Injection and Liposculpture for Gluteal Reshaping in Koreans

PURPOSE: Together with the breast, buttocks are an important element of attractive body contour. To make a beautiful buttocks, improvement of body contour around the buttock as well as buttock augmentation and lifting is also important. The authors investigated characteristic features of buttocks in Koreans and report about the results of liposculpture and autologous fat injection for improving buttock's contour. METHODS: We performed a retrospective study of 21 patients who would like to gluteal reshaping. We checked about buttock's ptosis, projection, depression, gluteal retraction and excessive fat accumulation around buttocks. Depending on it, we performed liposculpture and autologous fat injection. Under general anesthesia, we harvested fat from excessive fat accumulation areas around buttocks, and injected into buttocks medio-superiorly. Postoperatively, pillows were positioned on the bed not to press the buttocks which were injected with the fat. RESULTS: Based on the shape of buttocks, A-shape is seen in 4 cases(19%), V-shape 3 cases(14%), square-shape 9 cases(43%), round-shape 5 cases(24%). Based on the Gonzalez's ptosis grading method, 1 degree ptosis is 1 case(4%), 2 degree ptosis is 6 cases(29%), 3 degree ptosis is 8 cases(38%), 4 degree ptosis is 6 cases(29%). There were no complications such as infection, hematoma, pain, dysparethesia. The subjective assessment of surgical results by patients was excellent. CONCLUSION: To make a beautiful buttock, improvement of body contour around the buttock as well as buttock augmentation and lifting is also important. Liposculpture and autologous fat grafting are very safe, useful and easy methods for improving buttock's contour.

Anterior Ischemic Optic Neuropathy Following Periocular Autologous Fat Injection

PURPOSE: To report an unusual case of anterior ischemic optic neuropathy and choroidal ischemia after injection of autologous fat into the periorbital region due to embolism of the short posterior ciliary artery without involving the retinal artery. CASE SUMMARY: A 39-year-old female presented with sudden blurred vision, diplopia and ptosis of her left eye immediately after receiving an autologous fat injection into the periorbital area. The first ophthalmologic examination revealed that the patient s left eye had decreased visual acuity, relative afferent pupillary defect, exotropia, and hypertropia. Fundus examination of the left eye showed disc edema. Fluorescein angiography showed multiple choroidal vascular filling defects at the early phase and wedge-shaped or geographic fluorescein staining at the superior, inferior, and temporal peripheral areas at late phase. Humphrey visual field test results disclosed an inferior visual field defect. On the follow-up visit after oral steroid therapy (prednisolone 30 mg) for 7 days, diplopia disappeared and visual acuity recovered to 1.0. The inferior visual field defect and relative afferent pupillary defect were still present.

Correction of Sunken Eyelid with Unfavorable Fold Using Autologous Fat Injection

PURPOSE: Sunken eyelid is a deformity of upper eyelid due to atrophy of periocular fat tissue, loss of skin elasticity. It causes the skin retraction of eyelid and unfavorable fold. Sunken eyelid occurs from the results of natural aging process, facial trauma, complication of previous periocular surgery, etc. We acquired a satisfied correction of sunken eyelid and unfavorable fold using autologous fat injection only. The aim of this study is a assessment of autologous fat injection for correction of sunken eyelid accompanied with unfavorable fold. METHODS: From August 2002 to March 2006, we performed 37 cases of correction of sunken eyelid with unfavorable fold using autologous fat injection. They were all females with ages ranged from 23 to 63. Fat was harvested from lower abdomen and centrifuged with Coleman system. Multi-layered injection of purified fat was done from orbital fat layer to orbicularis oculi muscle. RESULTS: Overall, improvement of sunken eye and unfavorable fold was observed in the majority of the patients. Discomfort of eye opening was improved in 24 patients. The average injection volume was 1.33mL in right eyelid, 1.31mL in left eyelid at first injection. Second injection was done in patients who absorption of injected fat was noted with. No specific complications were observed. CONCLUSION: Natural and attractive upper eyelid was acquired from fat injection only in sunken eyelid with unfavorable fold. To the authors' knowledge, it is desirable for sunken eyelid accompanied with unfavorable fold to be treated with autologous fat injection at first. Although some shortcomings are substantial, autologous fat injection is easy and effective method for correction of unfavorable fold in sunken eyelid without specific complication.

Visual Disturbance following Autologous Fat Injection into Periorbital Area

PURPOSE: Autologous fat injection into the facial area is a frequently used technique in aesthetic plastic surgery for augmentation of the soft tissue. Fat injection is a very safe procedure because of the advantage of being autologous tissue. Minimal foreign body reaction or infections are noted after fat injection. However, there may be some complications including those as severe as blindness. There have been some case reports on visual disturbances after autologous fat injection reported in the literature. METHODS: A 21-year-old female patient underwent autologous fat injection into left eyebrow area to correct depression of soft tissue. Immediately after injection of autologous fat, she complained sudden visual loss on the left eye. She had come to our emergency room and ophthalmologic evaluation showed that the patient could only recognize hand motion. There was no abnormality of the optic nerve on magnetic resonance imaging. Suspecting an ischemic optic neuritis from fat embolism of the central retinal artery, the patient was treated conservatively with occular massage, antiglaucomatic agent, anti-inflammatory drugs and antibiotics. Visual field examination showed visual defect of half the lower hemisphere. RESULTS: While maintaining antiglaucomatic agents and non steroidal anti inflammatory drugs, fundoscopic examination showed no abnormalities on the second day of admission. Visual field examination showed an improvement on the fourth day along with decreased eyeball pain. Significant improvement of vision was noted and the patient was discharged on the fifth day of admission. The patient was followed-up 2 days afterwards with improved vision and visual field defect. CONCLUSION: We describe an unusual case of sudden unilateral visual disturbance following autologous fat injection into periorbital area.

The Initial Experience of Endoscopic Periurethral Autologous Fat Injection in Stress Urinary Incontinence / 대한비뇨기과학회지

Stress urinary incontinence is mainly treated by major surgical procedures. Bolstering the urethra with injectable compound is an attractive, although not new, procedure for stress urinary incontinence. Recently it has been popularized to use the autologous fat for injection. A total of 6 women with stress urinary incontinence underwent periurethral injection of autologous fat. Patients' age ranged from 41 to 69 years( mean 55.8). The fat was harvested from the low abdominal wall by liposuction unit. Follow up was 2 to 10 months( mean 6.8). of the patients, 5(83%) are cured, 1 is improved significantly( from Grade III to I). We conclude that the periurethral autologous fat injection is a reliable, safe, low-cost, and high benefit procedure.

Autologous fat injection and collagen impantation for the correction of facial atroply / 대한피부과학회지
