Abstract
BACKGROUND Autologous fat is a rich source of adipose tissue that is safe for transplantation. Decreasing the long-term absorption rate is key to improve the survival of transplanted adipose tissue. The aim of this study was to assess the effect of concentrated growth factor (CGF) on the survival of transplanted adipose tissue for repair of facial depression malformations. METHODS Coleman adipose granules (CAGs) were prepared from venous blood. In the animal experiment, the ears of 30 healthy male New Zealand white rabbits were randomly allocated to 1 of 4 groups: CGF + CAG (CGF group), platelet-rich fibrin (PRF) + CAG (PRF group), CAG alone (CAG group), and adipose granule transplantation group (control group). Postoperative survival of the transplanted adipose tissue was assessed, the survival and absorption rates of adipose were calculated, and immunohistochemical analysis of specimens was conducted by staining with hematoxylin and eosin and Oil Red O. Of 43 outpatients, 22 received simple adipose transplantation and 21 received autologous CGF combined with adipose transplantation. The adipose absorption rate, complication rate, and cosmetic improvement of the 2 groups were compared. RESULTS More adipocytes that are normal were observed in the CGF group, with fewer vacuoles and more uniform distribution of adipose tissue. Survival of the adipose tissue was superior in the CGF and PRF groups. Meanwhile, vascular density and long-term stability were better in the CGF group than the PRF group. In terms of clinical efficacy, the uniformity and survival rate of the adipose tissue were relatively improved in the CGF group compared with the simple adipose particle transplantation group, with less early liquefaction. CONCLUSION Concentrated growth factor stabilized and improved the survival of transplanted adipose tissue for filling of facial depression malformations.

Safety and Aesthetics of Autologous Dermis-Fat Graft after Parotidectomy: A Multidisciplinary Retrospective Study. J Pers Med 2023; 13:1200. [PMID: 37623451 PMCID: PMC10456015 DOI: 10.3390/jpm13081200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 07/26/2023] [Accepted: 07/27/2023] [Indexed: 08/26/2023] Open
Abstract
(1) Background: In surgical procedures for maxillofacial tumours, it is challenging to preserve functional and cosmetic properties in the affected patients. The use of fat grafting is considered as a valuable alternative to overcome postoperative aesthetic asymmetry problems. (2) Methods: In this study, we enrolled thirty patients with parotid gland tumours in which a partial or complete parotidectomy was performed with positioning in the parotid bed of autologous dermis-fat grafts. We evaluated the satisfaction rate of the patients and the objective efficacy in solving the deformity by comparing MRI data before and after surgery. (3) Results: Twenty-six patients showed a satisfying cosmetic result with proper facial symmetry between the affected side and the healthy one. Two patients presented mild postsurgical complications such as haematomas, and two patients reported temporary weakness of the facial nerve related to the parotidectomy. (4) Conclusions: Based on the imaging data obtained via MRI before and after surgery, we can assess that the employment of fat grafts in parotidectomy surgical procedures gives good cosmetic results and does not affect the post operative management and follow up of oncologic patients.

Abstract
A 12-year-old female with a history of multicentric infantile myofibromatosis (IM) presented with a tender, enlarging cheek mass and trismus. Imaging identified an intramasseteric tumor. Given the unknown etiology of the tumor and her bothersome symptoms, the mass was excised using a transoral approach with concurrent facial nerve monitoring. Her pathology report confirmed the diagnosis of a myofibromatosis lesion embedded within the masseter muscle. While IM can often present with lesions in the head and neck region, the intramasseteric location is rare and presents unique considerations for surgical approach. Myofibromatosis lesions typically occur before two years of age, although there are some rare documented cases of multicentric myofibromatosis lesions presenting at older ages. Furthermore, this patient's family history of similar lesions suggests a familial variant, which may have implications for disease behavior and need for further work-up, monitoring, and management. Overall, this was an unusual presentation of IM given the patient's age, prevalent family history, and the location of the mass. This case report adds to the literature and discusses the clinical differential of a pediatric cheek mass, the surgical considerations for an intramasseteric tumor, and the natural history of infantile myofibromatosis.

[PMID: 34772563 DOI: 10.1016/j.anl.2021.10.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 10/09/2021] [Accepted: 10/20/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE Concave deformities and gustatory sweating are the most common complications that cause substantial patient dissatisfaction after parotidectomy. Various surgical methods to prevent these complications have been described. However, effective techniques have not been established, especially in patients with medium- to large-sized parotidectomy defects. We evaluated the utility of infrahyoid myofascial flap reconstruction of parotidectomy defects for the prevention of these complications. METHODS We conducted a retrospective case series study in patients with a benign or malignant parotid tumor measuring over 4 cm who underwent immediate pedicle infrahyoid myofascial flap reconstruction after total or subtotal parotidectomy or total resection of either the superficial or deep parotid gland at our hospital. Subjective analyses of facial symmetry, postoperative concave deformities of the anterior neck, gustatory sweating, voice disorders, odynophagia, neck scarring in the parotid and anterior neck areas, sensory disorders, pain, and neck stiffness were performed using patient interview data. Objective evaluations of facial symmetry were made by the first or second author. Both analyses were performed after a follow-up of more than six months. Additionally, patient demographic data, clinicopathological factors, parotidectomy and skin incision types, flap survival, and postoperative complications were evaluated. RESULTS We included eight patients (male, n=5; mean age, 69.3 years [range, 37-93 years]). Procedures included total or subtotal parotidectomy (n=4), superficial lobe parotidectomy (n=2), and deep lobe parotidectomy with partial superficial lobe parotidectomy (n=2). Infrahyoid myofascial flaps reached the cranial tip of the parotid defect without tension, and their volume sufficiently filled the parotidectomy defect in all patients. There were no local signs of insufficient blood flow within the transferred flaps. OBJECTIVE AND SUBJECTIVE: assessments were made after a mean duration of 1.2 years (range, 0.6-1.8). Postoperatively, no patient subjectively reported facial asymmetry. Objectively, facial symmetry was "good" in four patients and "fair" in four patients. No distinctly visible concave deformity in the parotid or anterior neck area occurred in any patient. Gustatory sweating occurred in one patient; this individual had the largest parotidectomy defect. Only one patient experienced donor site morbidity (mild anterior neck stiffness) related to infrahyoid myofascial flap elevation. CONCLUSION Although complete prevention of gustatory sweating was unsuccessful, infrahyoid myofascial flap reconstruction of medium- to large-sized parotidectomy defects led to postoperative facial symmetry with minimal donor site morbidity.

Abstract
OBJECTIVE The contour defect resulting after parotidectomy can be cosmetically unappealing. Multiple reconstructive efforts have been reported to mitigate this problem. We describe a novel technique of vascularized parascapular fat reconstruction based on the circumflex scapular vessels and evaluate its outcomes. METHODS Consecutive patients who underwent parotidectomy with or without additional resections and vascularized parascapular fat flap reconstruction in 2020 were included. Demographic, morphologic, intraoperative, and postoperative data were assessed. RESULTS Eight patients (3 female) were included. Median cut-to-close time was 247 (range 209-298) minutes, including tumor ablation. None of the patients had any wound complications, and all except one was discharged on postoperative day 1. Flap monitoring was not performed. None reported any significant donor site morbidity except scar formation. At last follow up, all patients reported satisfactory facial contour. CONCLUSION Vascularized parascapular fat flap reconstruction of parotidectomy contour defects has satisfactory cosmetic outcomes with minimal morbidity and short hospitalization courses.

Abstract
BACKGROUND Prevention of Frey syndrome (FS) after parotidectomy using an interposition barrier has long been gaining a wide popularity; however, there is no clear evidence regarding which preventive technique is more effective. The aim of this network meta-analysis (NMA) is to answer the question: What is the best method for prevention of FS after parotidectomy? METHODS A comprehensive search of the PubMed, Embase, SCOPUS, and Cochrane library was conducted to identify the eligible studies. The outcome was the incidence of subjective Frey syndrome (SFS) and objective Frey syndrome (OFS). The Bayesian NMA accompanied with a random effects model and 95% credible intervals (CrIs) were calculated using GeMTC R package. RESULTS Thirty-four studies (n = 2987 patients) with five interventions, namely Alloderm (ADM), temporoparietal fascia (TPF), sternocleidomastoid muscle (SCM), superficial musculoaponeurotic system (SMAS), and free fat graft (FFG), were compared together and with no interposition barrier (NB). The results of NMA showed a statistically significant reduction in both SFS and OFS when ADM, TPF, SMAS, FFG, and SCM were compared with NB. No statistical differences were observed when comparing ADM, SCM, SMAS, FFG, and TPF. TPF ranked the best of all treatments (59.4%) and was associated with the least incidence of SFS; whereas ADM ranked the best of all treatments (61.1%) and was associated with the least incidence of OFS. CONCLUSIONS All interventions (TPF flap, ADM, FFG, SMAS, and SCM) were associated with a significant reduction in the incidence of FS when compared with NB. TPF and ADM showed the best outcome with the least incidence of SFS and OFS, respectively.

Abstract
Complex craniofacial wounds (CCW) are those refractory to initial treatment and may involve chronic infection, exposed hardware, irradiated tissue, and soft tissue volume loss. Typical reconstruction with microvascular flaps involves considerable morbidity. While free dermal fat autografting (DFA) is used extensively in many applications, its use treating CCW remains an unexplored but attractive possibility. Data from a retrospective cohort of 34 consecutive patients (13 male; 21 female and aged 2-79-years), who underwent free DFA between 1985 and 2018 for CCW by a single plastic surgeon, were analyzed. Post-operative follow-up was 1-24 years (M = 6.53, SD = 7.91). Many patients had several concomitant wound complications. Primary pre-operative wound complications were dominated by infection (N = 20), of which over 75% (N = 15) were associated with non-autogenic material. Eighteen had resolution of their pre-operative infection. Of the total (N = 34), 79.41% had stable grafts at follow-up [X(3) = 54, P < 0.001], with only 3 experiencing observable atrophy and 1 graft necrosis. Most of the cohort was complication free [X(1) = 7.53, P = 0.006], with 73.53% experiencing no problems involving the graft. Twenty-nine (85.29%) of 34 patients had therapeutic success with free DFA [X(1) = 28.65, P < 0.001]. Pre-operative wound status (β = 1.13, P < 0.001) predicted therapeutic success [R = 0.87, F(7,9) = 8.94, P = 0.002]. While 5 (14.71%) did not have therapeutic success, no additional problems arose related to grafts. Free DFA appears to be beneficial and show low morbidity. Future studies must evaluate these findings. In this context, their use should be considered in recalcitrant craniofacial wounds.
