[PMID: 34228210 PMCID: PMC8260705 DOI: 10.1186/s40902-021-00306-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 06/15/2021] [Indexed: 11/15/2022] Open
Abstract
Background The pedicled buccal fat pad has been used for a long time to reconstruct oral defects due to its ease of flap formation and few complications. Many cases related to reconstruction of defects in the maxilla, such as closing the oroantral fistula, have been reported, but cases related to the reconstruction of defects in the mandible are limited. Under adequate anterior traction, pedicled buccal fat pad can be a reliable and effective method for reconstruction of surgical defects in the posterior mandible. Case presentation This study describes two cases of reconstruction of surgical oral defects in the posterior mandible, all of which were covered by a pedicled buccal fat pad. The size of the flap was sufficient to perfectly close the defect without any tension. Photographic and radiologic imaging showed successful closure of the defects and no problems were noted in the treated area. Conclusion In conclusion, the pedicled buccal fat pad graft is a convenient and reliable method for the reconstruction of surgical defects on the posterior mandible.

Abstract
Objectives The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis. Materials and Methods Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (≥35 mm) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle. Results With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed. Conclusion Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.

Abstract
Integrity of the palatal mucosa may be disrupted due to various pathological and congenital factors. In maxillofacial defects, the buccal fat pad has been used frequently to repair the palatal region and close oro-nasal communications. In this case report, the use of buccal fat pad for the closure of a surgical palatal defect is presented with a 3-year follow-up. A 75-year-old female patient visited our clinic with a complaint of a non-adaptive maxillary denture. During clinical and radiographic examination, a well-demarcated mass on the palatal mucosa extending to the soft palate of the left side was observed. Subsequent to resection of the tumor, a defect occurred on the palatal region extending toward the soft palate. The pedicled buccal fat pad was chosen for closure of the defect. The patient was followed-up at 3, 7, 14, and 30 days after surgery. Epithelization and healing of the surgical wound were uneventful. At the 3-year follow-up, functional closure of the left palatal region was observed with no recurrence. Buccal fat pad is an easily manipulated flap with predictable results for the reconstruction of medium-sized defects of the oral and maxillofacial region with minimal postoperative discomfort for the patient.

Abstract
OBJECTIVE The objective of this study was to assess the effectiveness of collagen membrane as biological dressing over buccal fat pad (BFP) during crucial postoperative healing phase in the surgical management of oral submucous fibrosis (OSMF). STUDY DESIGN The study comprised of 40 patients of OSMF of group IVa (Khanna and Andrade). Patients were randomly divided in two groups (20 patients in each group). Group I patients were treated using buccal fat pad only, whereas collagen membrane was used as a covering over harvested BFP in group II patients. Postoperative follow-up was done at 1 week, 3 weeks, 6 months and 1 year. RESULT Mean postoperative mouth opening achieved in both the groups was comparable at every follow-up visit. Infection was evident in four patients of group I at 1-week follow-up, whereas none of the group II patients developed infection. Pain score was lesser in group II patients as compared to group I. Relapse was seen in two patients in group I and one patient in group II. Time taken for epithelialization was 2-3 weeks in both the groups. CONCLUSION Although intraoperative time was increased in group II application of collagen membrane reduced infection when compared with group I. Also, the chances of damage to BFP are reduced during the hygiene maintenance at surgical site and jaw-opening exercise. Reduction in pain scores during postoperative period in group II patients was an additional advantage.

Abstract
The advantages of adipose-derived stem cells (AdSCs) over bone marrow stem cells (BMSCs), such as being available as a medical waste and less discomfort during harvest, have made them a good alternative instead of BMSCs in tissue engineering. AdSCs from buccal fat pad (BFP), as an easily harvestable and accessible source, have gained interest to be used for bone regeneration in the maxillofacial region. Due to scarcity of data regarding comparative analysis of isolated AdSCs from different parts of the body, we aimed to quantitatively compare the proliferation and osteogenic capabilities of AdSCs from different harvesting sites. In this study, AdSCs were isolated from BFP (BFPdSCs), abdomen (abdomen-derived mesenchymal stem cells (AbdSCs)), and hip (hip-derived mesenchymal stem cells (HdSCs)) from one individual and were compared for surface marker expression, morphology, growth rate, and osteogenic differentiation capability. Among them, BFPdSCs demonstrated the highest proliferation rate with the shortest doubling time and also expressed vascular endothelial markers including CD34 and CD146. Moreover, the expression of osteogenic markers were significantly higher in BFPdSCs. The results of this study suggested that BFPdSCs as an encouraging source of mesenchymal stem cells are to be used for bone tissue engineering.

Abstract
INTRODUCTION Autogenous grafting with lipoaspirate and dermo-fat grafting are popular techniques employed by plastic surgeons for correcting small volume facial defects and contour deformities. These techniques however present certain disadvantages. In this article, we present the use of the buccal fat pad graft as an alternative method of correcting such facial deformities. PATIENTS AND METHODS Free buccal fat pad grafting was carried out in 15 patients in our institution. All were harvested using an intraoral approach. The buccal fat pad graft was used to correct periorbital contour depressions, nasal tip deformities, as a camouflage graft over exposed silicon nasal implants and as a filler in the depression deformity after mass excision. RESULTS All 15 patients demonstrated good contour deformity correction without a significant graft resorption up to 3 years of follow-up. There were no donor site complications. The amount used ranged from 1 to 5 cc in volume as a spacer or barrier for the moderate-sized volume defect or depression, even though more than 5 cc of fat graft could be harvested if required. CONCLUSION In conclusion, the buccal fat pad graft represents an easy, expedient and exceptional tool for the correction of contour deformities, volume replacement or for aesthetic augmentation.

Abstract
Adipose tissues hold great promise in bone tissue engineering since they are available in large quantities as a waste material. The buccal fat pad (BFP) is a specialized adipose tissue that is easy to harvest and contains a rich blood supply, and its harvesting causes low complications for patients. This review focuses on the characteristics and osteogenic capability of stem cells derived from BFP as a valuable cell source for bone tissue engineering. An electronic search was performed on all in vitro and in vivo studies that used stem cells from BFP for the purpose of bone tissue engineering from 2010 until 2016. This review was organized according to the PRISMA statement. Adipose-derived stem cells derived from BFP (BFPSCs) were compared with adipose tissues from other parts of the body (AdSCs). Moreover, the osteogenic capability of dedifferentiated fat cells (DFAT) derived from BFP (BFP-DFAT) has been reported in comparison with BFPSCs. BFP is an easily accessible source of stem cells that can be obtained via the oral cavity without injury to the external body surface. Comparing BFPSCs with AdSCs indicated similar cell yield, morphology, and multilineage differentiation. However, BFPSCs proliferate faster and are more prone to producing colonies than AdSCs.

Abstract
RATIONALE Tissue augmentation of facial depression deformities can be achieved by volume replacement with autologous fat injection, dermal filler injection, etc. Here, we report a case of tissue augmentation of a facial depression deformity using a pedicled buccal fat pad (BFP). PATIENT CONCERNS A 64-year-old woman was referred with a chief complaint of facial depression deformity. DIAGNOSES Her molars had been removed at another hospital 12 years prior to this referral, and the patient suffered from a left cheek depression deformity as a sequela of a postextraction infection. INTERVENTIONS An incision was made in the left gingivobuccal sulcus under local anesthesia, and BFP was carefully excised from its normal location. The subcutaneous scar tissue was dissected, and a pocket was created via the same mucosal incision. BFP was then pushed into the pocket. OUTCOMES The depression deformity immediately disappeared postoperatively. The transplanted BFP remained unabsorbed and soft 43 months postoperatively. The patient did not have any complications. LESSONS This novel procedure has 2 advantages. First, the pedicled BFP is a vascularized tissue and is not absorbed postoperatively; control of contour is easy, and only 1 treatment session is required. Complications associated with fat necrosis can be avoided. Second, only a single intraoral incision is required; the risk of donor-site morbidity is very low, and scar formation does not occur on exposed skin. Third, this procedure can be performed without special instruments and equipment. The main disadvantages are limited rotation arc and volume of pedicled BFP. Despite its limited application, this procedure is simple and useful, with low invasiveness.

Abstract
Introduction: Peri-implantitis is a common condition, but no particular treatment protocol has shown to be definitively effective. Fat tissue in the oral cavity is widely available and easily accessed. The aim of the current study is to present a novel technique in the treatment of peri-implant lesions, utilizing a free fat tissue graft from the buccal fat pad (BFP). Patients and Methods: Free fat graft (FFG) was harvested from the BFP in eight patients and used with bone substitutes to regenerate 22 peri-implant lesions. Mechanical debridement of the implants surface and the granulation tissue were made with curettes or with Er: YAG laser. Clinical parameters such as plaque index, bleeding on probing, pocket depth, gingival recession, and the clinical attachment level were recorded as a baseline during the follow-up period. In addition, radiological evaluation was made preoperative during the follow-up period. Results: The donor site of the free fat graft was healed without cosmetic defect in all patients. Twenty-two peri-implant lesions were followed up for 12 months. Bleeding on probing and the pocket depth were significantly improved, and the clinical attachment level was achieved and maintained during the follow-up period due to the fibrous healing of the free fat graft. Satisfactory esthetic and functional outcomes of the treated implants were achieved and maintained. Conclusions: Free buccal fat graft heals by fibrosis. The fibrotic tissue adheres strongly to the implant surface and with stand the recurrence of the peri-implant lesion and provides stable and predictable outcome.

Abstract
Introduction Adipose-derived stem cells (ASCs) are progenitor cells used in bone tissue engineering and regenerative medicine. Despite subcutaneous adipose tissue being more abundant, the buccal fat pad (BFP) is easily accessible for dentists and maxillofacial surgeons. For this reason, considering the need for preclinical study and the swine as an optimal animal model in tissue engineering applications, we compared the features of porcine ASCs (pASCs) from both tissue-harvesting sites. Methods ASCs were isolated from interscapular subcutaneous adipose tissue (ScI) and buccal fat pads of six swine. Cells were characterized for their stemness and multipotent features. Moreover, their osteogenic ability when cultured on titanium disks and silicon carbide-plasma-enhanced chemical vapor-deposition fragments, and their growth in the presence of autologous and heterologous serum were also assessed. Results Independent of the harvesting site, no differences in proliferation, viability, and clonogenicity were observed among all the pASC populations. Furthermore, when induced toward osteogenic differentiation, both ScI- and BFP-pASCs showed an increase of collagen and calcified extracellular matrix (ECM) production, alkaline phosphatase activity, and osteonectin expression, indicating their ability to differentiate toward osteoblast-like cells. In addition, they differentiated toward adipocyte-like cells, and chondrogenic induced pASCs were able to increase glycosaminoglycans (GAGs) production over time. When cells were osteoinduced on synthetic biomaterials, they significantly increased the amount of calcified ECM compared with control cells; moreover, titanium showed the osteoinductive effect on pASCs, also without chemical stimuli. Finally, these cells grew nicely in 10% FBS, and no benefits were produced by substitution with swine serum. Conclusions Swine buccal fat pad contains progenitor cells with mesenchymal features, and they also osteo-differentiate nicely in association with synthetic supports. We suggest that porcine BFP-ASCs may be applied in preclinical studies of periodontal and bone-defect regeneration.

Abstract
Adipose-derived stem/stromal cells (ASCs) are progenitor cells used in bone tissue engineering and regenerative medicine. Since Bichat's fat pad is easily accessible for dentists and maxillo-facial surgeons, we compared the features of ASCs from Bichat's fat pad (BFP-ASCs) with human ASCs from subcutaneous adipose tissue (SC-ASCs). BFP-ASCs isolated from a small amount of tissue were characterized for their stemness and multidifferentiative ability. They showed an important clonogenic ability and the typical mesenchymal stem cell immunophenotype. Moreover, when properly induced, osteogenic and adipogenic differentiation markers, such as alkaline phosphatase activity, collagen deposition and lipid vacuoles formation, were promptly observed. Growth of both BFP-ASCs and SC-ASCs in the presence of human serum and their adhesion to natural and synthetic scaffolds were also assessed. Both types of ASCs adapted rapidly to human autologous or heterologous sera, increasing their proliferation rate compared to standard culture condition, and all the cells adhered finely to bone, periodontal ligament, collagen membrane, and polyglycol acid filaments that are present in the oral cavity or are commonly used in oral surgery. At last, we showed that amelogenin seems to be an early osteoinductive factor for BFP-ASCs, but not SC-ASCs, in vitro. We conclude that Bichat's fat pad contains BFP-ASCs with stemness features that are able to differentiate and adhere to biological supports and synthetic materials. They are also able to proliferate in the presence of human serum. For all these reasons we propose BFP-ASCs for future therapies of periodontal defects and bone regeneration.
