Sinusectomia maxilar via endoscópica como tratamento da rinossinusite crônica oriunda de fístula oroantral / Maxillary sinusectomy via endoscopy as treatment of chronic rhinosinusitis from oroantral fistula

O seio maxilar define-se por um espaço pneumático na maxila bilateralmente que possui volume e proximidade com os ápices de 2º pré-molares e molares superiores, possibilitando que intervenções nestes afetem sua integridade, levando a inflamação e podendo resultar em Rinossinusite Crônica (RSC).  Este estudo visa elucidar a atribuição da cirurgia endoscópica para tratamento da RSC através de um relato de caso clínico. Paciente sexo masculino, 50 anos, compareceu ao serviço de CTBMF do Hospital da Restauração – PE, com algesia em região zigomático-maxilar direita e comunicação oroantral, há sete meses, por exodontia traumática do elemento 15, já submetido à terapêuticas clínicas, sem sucesso. Diagnosticou-se ao exame físico e de imagem, RSC secundária, optando pela sinusectomia via endoscópica ântero-posterior acessando o seio maxilar direito por antrostomia maxilar na parede nasal lateral, removendo a mucosa doente e instalando um dreno de manutenção. Concomitantemente, fechou-se a comunicação bucossinusal por um retalho na mucosa vestibular maxilar recobrindo toda falha, sob anestesia geral. No pós-operatório imediato, iniciou-se antibioticoterapia, analgesia e irrigação com soro fisiológico 0,9%, pelo dreno, removido após 72 horas. A cirurgia endoscópica como tratamento da RSC mostra-se uma alternativa quando há falha terapêutica clínica, apresentando melhora da sintomatologia e qualidade de vida dos pacientes.

Applications of platelet- and leukocyte-rich fibrin (L-PRF) in Oral and Maxillofacial Surgery

Introduction: Oral and maxillofacial surgery plays a crucial role in the reconstruction and restoration of facial structures, seeking to improve both aesthetics and function. The use of platelet-rich fibrin (L-PRF) represents a notable advance, accelerating healing and improving surgical outcomes. Materials and Methods: This review covers 710 studies from various electronic databases (PubMed, Scopus, Web of Science, Science Direct and Google Scholar). The aim is to thoroughly investigate the applications of platelet- and leukocyte-rich fibrin (L-PRF) in Oral and Maxillofacial Surgery and Traumatology. Results: The analysis reveals that L-PRF stands out as an effective autologous therapy in oral and maxillofacial surgery. Its application shows remarkable potential for accelerating the healing process, contributing significantly to the effectiveness of procedures. Discussion: L-PRF has emerged as an excellent choice in oral and maxillofacial surgery and traumatology, improving both the aesthetic and functional aspects of facial reconstructions. This highlights the relevance of this autologous therapy and its benefits in surgical practice. Conclusion: The applications of platelet and leukocyte-rich fibrin (L-PRF) in Oral and Maxillofacial Surgery and Traumatology are fundamental and promising. This advance represents not only a means of accelerating healing, but also a significant contribution to better aesthetic and functional results in surgical procedures in this area.Introduction: Oral and maxillofacial surgery plays a crucial role in the reconstruction and restoration of facial structures, seeking to improve both aesthetics and function.

Analysis of biomechanical tests using biological material to evaluate osseodensification in the preparation of the implanted bed: Bibliographic review

Aim: The objective of this review is to map the protocols of studies that used biological material to evaluate the primary stability of implants after the osseodensification technique in the preparation of the implant bed, as well as to quantitatively synthesize the biomechanical parameters obtained in these studies. Methodology: The protocol review question is: “What protocols are available in biomechanical laboratory tests that used biological material to assess primary stability after osseodensification in the preparation of the implant bed?”. Ex vivo or in vivo laboratory studies that report primary stability after osseodensification in the preparation of the implant bed will be included. The protocol considered the PCC (Problem, Concept and Context) strategy to guide data collection, as established by the Joanna Briggs Institute (JBI). The search strategy will consider Medical Subject Headings (MeSH) terms, synonyms and free terms about osseodensification, with no data limit, language, subject or type of search, in the MEDLINE (PubMed), Scopus, Web of Science and Embase databases. The selection will be carried out by two reviewers, independently and blindly, following the eligibility criteria, based on the title and abstract identified in the initial search. When the title and abstract are not clear enough, the article will be read in full. The categorization of studies will take into account the year of publication of the study, the type of study (Ex vivo, In vivo), type of animal, number of animals used, sample number, number of evaluated groups and method of data collection ( Insertion torque, ISQ, removal torque, micro CT and histology). The data obtained and extracted will be presented in table and text format and presented through the VOS (Visualization of Similarities) method. Ethics and divulgation: The final protocol will be submitted for registration in the Open Science Framework. Results obtained through the literature review will be submitted for publication in a peer-reviewed journal and presented at national conferences and scientific meetings. Conclusion: It is expected that the result obtained here will be able to identify gaps regarding the standardization of research protocols using biological material for studies with surgical techniques in implant dentistry, as well as to quantify the values of primary stability of implants after different techniques for milling the implant bed
