Abdominal Dermal Fat Graft Versus Nasolabial Flap in Oral Submucous Fibrosis: A Randomized Clinical Trial.

Introduction: A prospective study was conducted to find out an effective alternative in the form of non-vascularized abdominal dermal fat graft (ADFG) and to compare its efficacy with the vascularised nasolabial flap (NLF) for the treatment of oral submucous fibrosis (OSMF). Method: Comparative study comprising of 30 patients with Grade 3 and 4A OSMF, randomly divided into 2 groups: Group A (ADFG) and Group B (NLF). They were evaluated for mouth opening (MO), graft uptake, time taken for mucosalization, pain, intercommissure distance (ICD), scar, duration of surgery (DOS), patient satisfaction and thickness of masseter muscle on ultrasonography. Findings: At 6 months, MO improved by 22.4 and 36.2 mm in Group A and Group B, respectively. There was statistically significant difference (p < 0.05) seen for the values between the groups for all the parameters except for ICD and VAS score, which was statistically insignificant (p > 0.05). Intraoral hair growth, facial scar, orocutaneous fistula and commissure tear was seen in Group B. Complete necrosis of graft followed by recurrence was seen in three cases in Group A. Conclusion: NLF holds better as compared to ADFG in the management of OSMF. However, the cornerstone of success remains habit cessation and aggressive physiotherapy. The limitations of the study are small sample size and short duration of follow-up.

Temporomandibular joint re-ankylosis: a case report and literature review.

Re-ankylosis is a common postoperative complication of temporomandibular joint (TMJ) ankylosis surgery. Various surgical options to prevent reankylosis, both with and without interpositional material, have been discussed in the literature. However, no standardized protocol has been suggested for management or prevention of TMJ ankylosis. This paper discusses the probable causes behind TMJ re-ankylosis and presents a case of unilateral TMJ re-ankylosis, which was managed by gap arthroplasty using an autologous abdominal dermal fat graft as an interpositional material and closely monitored for signs of relapse. Autologous fat graft acted as an effective barrier between the glenoid fossa and mandibular condyle, thus preventing dead space, hematoma and heterotrophic bone formation. A brief review of the literature and update on TMJ re-ankylosis are also presented.

Dermal Fat Grafting to Reconstruct the Parotidectomy Defect Normalizes Facial Attention.

OBJECTIVES/HYPOTHESIS: Use validated eye-tracking technology to objectively measure 1) the attentional distraction of facial contour defects after superficial and total parotidectomy and 2) changes in attentional distraction with abdominal dermal fat graft reconstruction. METHODS: Standardized frontal and oblique facial images of 16 patients who had undergone superficial or total parotidectomy with or without fat graft reconstruction; four normal controls were obtained. One hundred casual observers were recruited to view these images, and gaze data were collected using a Tobii Pro eye-tracking system. Gaze durations for predefined facial areas of interest were analyzed using mixed-effects linear regression to test study hypotheses. RESULTS: For frontal images, total parotidectomy increased gaze to the operated parotid area compared to the contralateral nonoperated parotid area (92 milliseconds, 95% confidence interval [CI]: 48-138 milliseconds, P < .001). Fat grafting normalized the attentional distraction, with no difference in gaze time on the operated parotid region compared to normal control faces (P = .414). For oblique images, total parotidectomy increased gaze to the operated parotid area compared to the contralateral nonoperated parotid area (658 milliseconds, 95% CI: 463-854 milliseconds, P < .001). Fat grafting normalized this attentional distraction, with no difference in gaze time on the operated parotid region compared to normal control faces (P = .504). In both views, superficial parotidectomy demonstrated no significant attentional distractions, with or without fat grafting. CONCLUSIONS: This eye-tracking study objectively demonstrates that total parotidectomy results in a facial contour deformity that is distracting to observers, whereas superficial parotidectomy does not. For total parotidectomy, this attentional distraction can be normalized with dermal fat graft reconstruction. LEVEL OF EVIDENCE: 3b Laryngoscope, 131:E124-E131, 2021.

Use of dermal fat grafts for treating anetoderma with lipoatrophy following involution of hemangiomas.

Infantile hemangioma (IH) is a benign vascular tumor that gradually involutes over several years. Rapidly involuting congenital hemangioma (RICH) is the relatively rare congenital vascular tumor that is fully grown at birth and does not undergo postnatal growth and involutes during the first year. However, after involution of both IH and RICH, some have severe sequelae, such as redundant skin or conspicuous scarring, requiring additional treatment. We present the case of a 6-year-old girl with a concave deformity due to subcutaneous atrophy, skin darkening, and altered skin texture of her left zygomatic region following involution of a hemangioma. We successfully treated this patient by transferring a dermal fat graft. This technique can be beneficial for atrophic sequelae after regression of a hemangioma and is easy to perform and cosmetically effective.

Free Dermal Fat Graft for Reconstruction of Soft Tissue Defects in the Maxillofacial Region.

STUDY DESIGN: Facial contour deformities are a very challenging issue for aesthetic and reconstructive surgeons. Free dermal fat graft is a composite graft used for the reconstruction of soft tissue defects in the maxillofacial region. The free dermal fat graft is easily adapted and contoured intraoperatively and provides a soft, natural, and favorable appearance after augmentation of the soft tissue defects. OBJECTIVE: To assess the use of free dermal fat graft for reconstruction of soft tissue defects in the maxillofacial region in regard to graft success, percentage of overcorrection, any associated complications, and cone beam computed tomography scan linear measurements for defect's depth. METHODS: This is a prospective study that included a patients were grafted with free dermal fat graft for correction of facial soft tissue defects from November 2017 to July 2019. All patients possess a depression defect and facial asymmetry due to congenital facial deformities, post-traumatic deformities, and post-ablative surgical deformities. RESULTS: Eleven patients (8 males and 3 females) with a mean age of 33.7 years were enrolled in this study. Five regions in the maxillofacial area were grafted in 11 patients. The mean of the postoperative follow-up was 6 months. The percentage of graft overcorrection was 15%. The mean for graft survival was 94.4% with no serious complications reported. CONCLUSIONS: The autologous FDFG is a versatile and less invasive method in the reconstruction of facial soft tissue defects with a very good survival rate.

Parry Romberg Syndrome: Literature Review and Report of Three Cases.

Parry Romberg Syndrome or Progressive Hemifacial Atrophy is a rare disease usually affecting one side of face with loss of soft and hard tissues. The disease appears suddenly and is usually self-limiting in 2-10 years time. The loss of soft and hard tissue leads to aesthetic and functional deficits which are compounded by the presence of associated symptoms like neuralgia, migraine, epilepsy and ocular involvement. The degree of deformity depends on the age at which the disease manifests first; the younger the age, the more severe the deformity. These patients undergo severe psychological trauma and social problems. The exact etiology is not known, and treatment is largely cosmetic. A report of three cases and a literature review is presented.

Assessment of outcomes and complications of posterior pharyngeal wall augmentation with dermal fat graft in patients with Velopharyngeal Insufficiency (VPI) after primary cleft palate repair: A pilot study.

INTRODUCTION: Materials used for posterior pharyngeal wall augmentation have been associated with important complications (exogenous materials) or variable and unpredictable durability (exogenous and endogenous materials); therefore, introducing a different material for augmenting the posterior pharyngeal wall seems necessary for reviving this relatively forgotten technique.The purpose of this study was to emphasize on the use of a material associated with minimal complications and maximum recovery and durability in correcting VPI and the use of evaluative adjuncts such as nasoendoscopy and videofluoroscopy to assess surgical outcomes. METHODS: In a pilot study, 24 patients underwent posterior pharyngeal wall augmentation with dermal fat graft harvested from the low crease abdominal region. Early and late complications, autologous graft durability in posterior pharynx, and speech improvement were assessed. RESULTS: There was a significant improvement in hypernasality, nasal emission, and nasal grimace after posterior pharyngeal wall augmentation with dermal fat graft (p<0.0001). The authors observed no significant life-threatening complication. The most evident short-term complication was snoring, which occurred in five patients, and all relieved uneventfully. CONCLUSION: The authors believe that augmenting the posterior pharyngeal wall with dermal fat graft is effective in improving hypernasality in patients with moderate velopharyngeal gap size and relatively adequate velar motion. This method has minimal complication profile because of autologous tissue application.

Platelet-rich plasma to rescue an ulcerated orbital dermal fat graft.

INTRODUCTION: Central graft ulceration is a rare complication of an orbital dermal fat graft caused by diminished blood supply to the implant. This study reports on the efficacy and safety of the use of a single subconjunctival injection of autologous platelet-rich plasma to rescue an ulcerated orbital dermal fat graft. METHODS: Three patients, who had undergone autologous dermal fat graft to treat their anophthalmic socket, were given a 2-mL subconjunctival platelet-rich plasma injection in the exposed graft margins. Demographic and clinical features, treatment protocol, clinical course, complications and follow-up time are reported. In the preoperative examination, all the patients presented a primary epithelial defect of the dermal fat graft. RESULTS: There were no major complications such as necrosis or infection. One patient presented a small conjunctival granuloma at 1-month follow up. Mean postoperative follow-up duration was 13 (range: 10-16) months. By 1 month, the chronic epithelial defect had resolved with the graft integrated within the orbital tissues in all cases. All patients were referred for artificial prosthesis placement. CONCLUSION: Although further work is needed, our findings suggest that a single subconjunctival platelet-rich plasma injection could be an effective, safe and economic alternative to surgery to rescue an ulcerated orbital dermal fat graft.

Surgical and oncological outcomes of free dermal fat graft for breast reconstruction after breast-conserving surgery.

BACKGROUND: Oncoplastic breast surgery originated in order to improve the esthetic result of breast-conserving surgery (BCS). Autologous free dermal fat graft (FDFG) is an emerging oncoplastic technique to improve the cosmetic outcome of breast-conserving surgery. OBJECTIVES: The aim of this study was to analyze our experience with FDFGs in breast reconstruction after breast-conserving surgery. Oncological outcomes, surgical complications and cosmetic results were considered. MATERIAL AND METHODS: This retrospective chart review study considered all consecutive oncoplastic breast treatment by means of FDFG reconstruction during the period between September 2011 and September 2012 in our Clinic of Surgery (University of Udine, Italy). The data collected included patient and tumor characteristics and outcomes (cosmetic and oncological). RESULTS: During the study period, 37 women were treated by breast cancer surgery and immediate breast reconstruction by FDFG. At a 3-year follow-up, we found no cases of recurrence among breast cancer patients treated by FDFG; at a 18-month follow-up, we found a prevalence of 75.0% of women extremely satisfied with their oncoplastic surgery and a high prevalence of excellent or good cosmetic outcomes (70.3%) according to objective and subjective cosmetic assessment. CONCLUSIONS: Immediate breast reconstruction by FDFG after BCS in a population selected for a low risk of breast cancer recurrence seems to be an oncologically safe option, with a good cosmetic outcome and a high prevalence of women satisfied with the treatment.

Free dermal fat graft reconstruction of the head and neck: An alternate reconstructive option.

OBJECTIVES: Ablative procedures of the head and neck often result in significant facial and cervical irregularities and cosmetic asymmetry. The deformity resulting from ablative procedures of the head and neck is a significant source of cosmetic morbidity and postoperative dissatisfaction. Reconstruction of post-ablative defects in the head and neck can employ a broad range of techniques, ranging from primary closure to free tissue transfer. The free dermal fat graft (FDFG) is one such option and has been used to repair volume defects of varying sizes after common head and neck procedures such as parotidectomy. However, its use is largely undocumented in the literature. We seek to further illustrate the FDFG as an alternate method of reconstruction of head and neck defects. STUDY DESIGN: Non-randomized retrospective analysis. METHODS: The medical records of all patients who underwent primary autologous abdominal FDFG reconstruction of head and neck defects by a single surgeon at Vanderbilt University Medical Center from January 1997 to August 2010 were reviewed. All patients were called in order to assess their post-operative cosmetic satisfaction. RESULTS: Sixty-two patients were analyzed. Only three patients were found to have post-operative complications directly related to the FDFG. No complications were found at the donor site. Based on a telephone survey, the majority of patients were satisfied post-operatively with their cosmetic outcomes in the primary site and donor site. CONCLUSIONS: From our experience the FDFG is a cosmetically and functionally advantageous option for reconstruction of ablative procedures of the head and neck.

Modified Penile Augmentation by Dermal-Fat Graft in Post-Hypospadias Adults.

BACKGROUND: Although a considerable part of patients desire further improvement in penile size after hypospadias repairs, penile augmentation is only considered in patients with congenital penile hypoplasia or acquired penile retraction. Modified penile augmentation by free dermal-fat graft is introduced to satisfy these patients and improve surgical safety. METHODS: From April 2012 to December 2014, a total of 15 male adults after hypospadias repairs, aged 18-24 years, underwent modified penile augmentation which involved girth enhancement by a free dermal-fat graft and penile elongation (suprapubic skin advancement-ligamentolysis). A specially designed tunneling instrument was introduced to facilitate pericavernous thickening without degloving. Outcome evaluation was mainly based on objective penile measurements and results of the Male Genital Image Scale. RESULTS: With 6 months' follow-up, all patients had achieved excellent cosmetic results, with a significant average dimensional increase of 1.53 ± 0.23 cm in flaccid girth and 1.67 ± 0.24 cm in flaccid length. No erection deficiencies or urinary fistula occurred. Patients' perception of male genitalia improved postoperatively, with the average MGIS score rising from 31.73 ± 4.86 to 40.20 ± 4.54. CONCLUSIONS: This modified technique is safe and effective in enlarging penile size. The use of the specially designed tunneling instrument simplifies penile girth enhancement, avoiding unnecessary trauma to the neo-urethra and neurovascular bundle. It is confirmed that physical dimensional enhancement does contribute to improving their underestimation of penile size.

Immediate breast volume replacement using a free dermal fat graft after breast cancer surgery: multi-institutional joint research of short-term outcomes in 262 Japanese patients.

BACKGROUND: Immediate volume replacement using a free dermal fat graft (FDFG) has been proven safe with early postoperative benefits. The aims of the present study were to clarify adequate indications and risk factors associated with operative morbidity. PATIENTS AND METHODS: A multi-institutional analysis of partial mastectomy with immediate volume replacement with FDFG was undertaken in 14 hospitals specializing in breast cancer treatment. Clinical and oncological variables were analyzed to identify factors associated with postoperative complications. RESULTS: A total of 262 cases were analyzed. Considering the observation period and overlap of patients, 13 (5.4%) out of 242 patients had complications within 1 month of surgery while 7 (4.6%) out of 151 patients developed complications 1-12 months after surgery. Two hundred and eleven out of 242 patients were statistically examined using a multivariate analysis, which revealed that the weight of resected breast tissue, size of implanted FDFG (cranio-caudal length), and weight of implanted FDFG were associated with a higher likelihood of postoperative complications. CONCLUSIONS: Immediate breast volume replacement using a FDFG after breast cancer surgery should be done for selected patients with breast cancer to avoid postoperative complications. The prospective and larger investigations are warranted for the establishment of appropriate guidelines.

Histological findings of an autologous dermal fat graft implanted onto the pectoralis major muscle of a rat model.

BACKGROUND: The aim of this study was to investigate the maintenance of volume as a spacer by comparing vascular supply and apoptosis in an implanted autologous-free dermal fat graft (FDFG) and free fat graft (FFG). An autologous FDFG is a material used in plastic surgery and oncoplastic breast surgery that is ideal for immediate volume replacement after partial mastectomy because of its easy availability and minimal invasion of the donor site; however, immunohistochemical findings and survival procedures have not yet been reported. METHODS: An experimental protocol using a unique animal model was designed for the present study. The expression of vascular endothelial growth factor (VEGF) was measured in FDFGs and FFGs implanted onto the pectoral major muscle of Wistar rats. Thirty Wistar rats were divided into two groups and postoperatively 1, 2, 4, 8, and 16 weeks (POW1, 2, 4, 8, 16). Six samples from three rats in each group were used as control samples (POW0). RESULTS: The thickness of the implanted FDFG was not significantly different from the control sample at POW1, 2, 4, 8, and 16 between FDFG and FFG group; however, the thickness at POW8 and 16 was significantly lesser in the FFG group than in the control samples. The average proportion of fatty tissue to whole tissue ranged from 34.2 to 48.6 % in the FDFG group and from 57.2 to 76.7 % in the FFG group during the observation period; however, there was no significant difference in the proportion of fatty tissue between these two groups. There were no significant differences between the average number of VEGF-positive cells in the FDFG group and the FFG group at POW1, 2, 4, 8, and 16. The average number of TUNEL-positive cells in the early period at POW1 was significantly lower in the FDFG group than in the FFG group. CONCLUSIONS: This rat model was useful for investigating the mechanisms of angiogenesis, apoptosis, structure maintenance, and fibromatous changes. From the present experimental study, we believe that FDFG is one of the most convenient materials currently available to repair small defects at the time of BCS even in the clinical field.

Dermal fat graft from simultaneous abdominoplasty as an adjunct to revision aesthetic and reconstructive breast surgery: A poor man's acellular dermal matrix?

INTRODUCTION: The global use of acellular dermal matrices as an adjunct to tissue expander or implant-based breast reconstruction, by surgeons wishing to cover and support the inferior breast pole, has increased in frequency in the last two decades. However despite the reported enhanced cosmetic outcomes, issues regarding their cost effectiveness have led to their infrequent use within the UK National Health Service and the need for an equally efficacious but cheaper alternative. PRESENTATION OF CASE: We report two patients requiring bilateral revision breast surgery for severely asymmetrical, tender, ptotic breasts and cosmetically poor abdomens. Both were denied assisted acellular dermal matrix reconstructive surgery on the state NHS system and unable to afford the private costs. We therefore utilised free dermal fat grafts, harvested from concomitant abdominoplasties to extend the pectoralis major muscle and smoothen surface irregularities. DISCUSSION: Both patients achieved excellent cosmetic outcomes and aside from a small, spontaneously resolving abdominal site seroma in one patient, have remained free of any complications for over two years. This cost effective procedure is only feasible in patients with an adequate pannus who are amenable to the extra surgery and resultant scarring. CONCLUSION: We herein report the use of free dermal fat graft in revision aesthetic and reconstructive surgery in a manner akin to recent acellular dermal matrix use. The comparable enhanced aesthetic outcomes, minimal complication rate and substantial cost savings merit dissemination to a global audience and encourage surgeons to consider this economic alternative.

Abdominoplasty-derived dermal-fat graft augmentation gluteoplasty.

BACKGROUND: Plastic surgeons are exploring novel techniques for augmentation gluteoplasty as the demand for this procedure increases annually in the United States. OBJECTIVES: The authors retrospectively reviewed a series of lower abdominal dermal-fat graft augmentation gluteoplasties to validate the procedure. METHODS: Nine consecutive patients underwent abdominoplasty or torsoplasty in which 2 oval dermal-fat grafts were excised, de-epithelialized, and then implanted into subfascial gluteal pockets for augmentation. All operations were independently conducted by 1 of 2 surgeons at facilities in Maryland and New Jersey. RESULTS: The mean age of the 9 female patients was 46 years. The mean dermal-graft size was 188 cm(2), and the mean graft weight was 288 g. One graft became infected and required excision 39 days after the procedure. There were no other complications. All surviving grafts provided a substantial increase in posterior projection and long-lasting gluteal volume. CONCLUSIONS: Dermal-fat graft augmentation gluteoplasty provides a voluminous, natural-feeling, and durable aesthetic result. The procedure should be considered a viable option for patients undergoing abdominoplasty or torsoplasty, especially as more experience is gained. LEVEL OF EVIDENCE: 4.

Oncoplastic breast surgery for centrally located breast cancer: a case series.

Oncoplastic breast surgery (OBS), which combines the concepts of oncologic and plastic surgery, is becoming more common worldwide. We herein report the results of OBS in Japanese patients with centrally located breast cancer (CLBC) and Paget's disease. We performed OBS combining partial mastectomy and immediate volume replacement on patients with non-ptotic and/or small breasts, and volume reduction surgery for patients with ptotic breasts, as reported in Western countries. Japanese encounters are described in this report as a case series.

Free dermal fat graft for restoration of soft tissue defects in maxillofacial surgery.

Various local flaps have been used for reconstruction of developmental and post surgical soft tissue defects of maxillofacial region. They include nasolabial flap, palatal pedicled flap, buccal fat pad, temporalis muscle and fascia flap. An ideal flap for all indications is yet to be found. Our experience with free dermal fat graft in the correction of deformities associated with Parry Romberg syndrome and oral submucous fibrosis is presented.

Dermal-fat graft combined with secondary autologous fat transplantation to reconstruct severe facial depression / 中华医学美学美容杂志

Objective To investigate the method of dermal-fat graft combined with secondary autologous fat transplantation in repairing severe facial depression and to evaluate the clinical effects.Methods Twelve cases of facial depression had been repaired by the transplantation of dermal-fat flap which was removed from the abdomen at the first stage.They were given fat granules injection 1 to 3 times postoperatively,and 3,6 and 3 patients were given fat granules injection three times,twice and once,respectively,with the interval period of 3 to 6 months.The result was based on comparison of the photos taken from preoperation and postoperation.Results All patients were healed primarily except one of which was formed hematoma after operation and scavenged thereafter.After 6 months to 2 years follow-up,all the patients had satisfactory facial contour.Conclusions Combined autologous fat granules with free dermal-fat graft to reconstruct severe facial depress is an easy,safe and effective technique and deserves to be recommended.

Pubovaginal Sling Operation Using Dermal Fat Graft in Female Stress Urinary Incontinence / 대한비뇨기과학회지

PURPOSE: An autologous dermal fat graft has several advantages, over other viable or synthetic sling materials, in expenditure, postoperative complication and biocompatibility of the host. We investigated the success rate and risk factors of a pubovaginal sling, using an autologous dermal fat graft, in female stress urinary incontinence. MATERIALS AND METHODS: We retrospectively analyzed the medical records of 30 women that underwent a pubovaginal sling, using a dermal fat graft. The preoperative evaluations included: age, Stamey grade, Blaivas type, urodynamic study and previous pelvic operation history. We observed the postoperative results using questionnaire research during the follow-up (cured: no urine leakage and satisfactory, improved: urine leak4 times/week or unsatisfactory). The risk factors affecting the postoperative outcomes and complications were also analyzed. RESULTS: The success rate was 90.0% (success rate was calculated by cured rate plus improved rate, cured rate: 53.3%, improved rate: 36.7%), with the follow-up periods ranging from 6 to 24 months. A wound infection, requiring hospitalization, developed in one patient, but no other significant complications related to dermal graft were noted. Within the preoperative evaluations, the Blaivas type and a previous pelvic operation history were statistically related to the success rate (p<0.05). CONCLUSIONS: The Blaivas type and previous pelvic operation history are meaningful factors for predicting the success rate. The use of a dermal fat graft might be beneficial in the treatment of stress urinary incontinence in terms of its cost and success rate. However, a lower abdominal scar, of more than 5cm in length, and postoperative infections remain in some patients. Therefore it might be necessary to find another useful material for to treat female stress urinary incontinence.

Cutaneous Fistula in Patient with Augmentation Penoplasty / 대한남성과학회지

A man's self-esteem can be influenced by his external genitalia. If a man perceives his penis as inadequate size, whether real or imagined, such feelings invade his sexual activities. Most patients seek increased thickness and length to improve appearance during intercourse. Many men want to enlarge their penes despite of normal function or above average size. Dermal fat graft is extracted from a patient and penile augmentation with it is highly satisfactory since the amount of dermal fat graft absorption to the body itself is pretty low and rare cases of complication, and its natural appearance of penis without physical comfort. The most common complications after dermal grafting are penile skin edema and erythema. Sebaceous glands usually disappear within 2 weeks and hair follicles generally within 2 months. We report our experience with the evaluation and management of patient who present with uncommon penile cutaneous fistula after penile augmentation with dermal fat grafting.
