Introdução: O corpo adiposo bucal (CAB) foi descrito pela primeira vez por Heister, em 1732, como uma estrutura glandular, sendo sua natureza gordurosa definida, posteriormente, por Bichat, em 1802. Este tecido possui função mecânica, de proteção e estética, sendo a estrutura responsável pela determinação dos contornos faciais. Contudo, a literatura revela várias aplicações do CAB na reconstrução oral, incluindo o fechamento de defeitos cirúrgicos após a excisão de tumores, cirurgias para remoção de leucoplasias e fibroses submucosas, fechamento de fendas palatinas, cobertura de enxertos ósseos, revestimento da superfície do seio maxilar e reparo celular. Objetivos: Avaliar a morfologia do corpo adiposo bucal. Metodologia: Foi realizada uma revisão de literatura através de bases indexadoras Scielo e PubMed, utilizando os descritores “histology” e “buccal fat pad”. A busca foi realizada sem restrição de idioma da fonte das informações até 06 de setembro de 2021. Foram incluídos nesta pesquisa artigos completos e excluídos cartas ao Editor, opiniões individuais e livros. Resultados: Histologicamente, o corpo adiposo bucal consiste em um estroma de tecido conjuntivo contendo uma população celular heterogênea, dentre as quais podem ser destacadas células-tronco adiposas (ASCs). A literatura ainda indica que tais células podem se diferenciar em várias linhagens celulares, incluindo adipócitos, osteoblastos, condrócitos, miócitos, células neuronais, células endoteliais e hepatócitos. Ainda, o tecido adiposo secreta uma variedade de fatores de crescimento angiogênicos e antiapoptóticos. Muitos estudos demonstraram que produtos derivados de secreções de células-tronco mesenquimais (MSCs) possuem efeitos terapêuticos nos principais processos patológicos associados às funções homeostáticas básicas, como diferenciação e proliferação celular, angiogênese e vasculogênese, inflamação e estresse oxidativo.Cabe ainda ressaltar que, devido a essas propriedades, o corpo adiposo bucal está sendo usado em ensaios clínicos de várias patologias, incluindo doenças imunológicas e opção terapêutica no tratamento de pacientes infectados por SARS-COV-2. Conclusão: O corpo adiposo bucal pode ser considerado fonte de uma população celular heterogênea.

Abstract Purpose Maxillary bone grafts and implantations have increased over recent years despite a lack of maxillary bone quality and quantity. The number of patients referred for oroantral fistula (OAF) due to implant or bone graft failure has increased, and in patients with an oroantral fistula, the pedicled buccal fat pad is viewed as a robust, reliable option. This study was conducted to document the usefulness of buccal fat pad grafts for oroantral fistula closure. Materials and methods We retrospectively studied 25 patients with OAF treated with a buccal fat pad graft from 2015 to 2018. Sex, age, OAF location, cause, duration, presence of systemic disease, smoking, previous dental surgery, and side effects were investigated. Results A total of 25 patients were studied. Mean patient age was 54.8 years, and the male to female ratio was 19:6. Causes of oroantral fistula were cyst enucleation, tumor resection, implant removal, bone graft failure, and extraction. Excellent results were obtained in 23 (92%) of the 25 patients. In the other two patients that both smoked, a small fistula was observed during follow-up. No recurrence of oroantral fistula was observed after 2 months to 1 year of follow-up. Conclusions The incidence of oroantral fistula is increasing due to implant and bone graft failures. Oroantral fistula closure using a pedicled buccal fat pad was found to have a high success rate.

Abstract Background Since 2007, when the anatomy of facial fat compartment was described, an increasing number of studies on the aging process of the compartment of cadavers has emerged. Objectives The authors evaluated the aging changes of lateral facial fat compartments on the same person. Methods Sixty-three patients were included in this retrospective study. All patients had magnetic resonance imaging scans with at least 4 years apart. The authors targeted the fat compartments of the superficial temporal, subcutaneous temporal, and buccal fat pad, comparing the data on different time points. Results The thickness of the subcutaneous temporal fat did not change significantly. The 3 diameters of the superficial temporal fat compartment all became thinner on the axial view (P < 0.05). On the sagittal view, the superficial temporal fat elongated from 38.89 mm to 43.74 mm (P < 0.05). The buccal fat compartment also lengthened from 68.73 mm to 74.39 mm (P < 0.05) and had a positive correlation with follow-up duration only. Conclusions The study revealed the fat compartment change on the same person with time. The temporal hollow mainly originates from the thinner part of the superficial temporal fat. The descending of the buccal fat pad aggravates the labiomandibular fold. By understanding the aging process more fully, we can rejuvenate our patients more naturally.

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.
