O objetivo do presente estudo foi avaliar a efetividade do uso de injeções de ácido hialurônico em procedimentos de artroscopia em pacientes com desordens temporomandibulares (DTMs). A metodologia empregada para alcançar o intuito proposto foi uma revisão da literatura atualmente disponível e conduzida nas bases de dados MEDLINE via PubMed, Scopus, Scielo e Bireme, por meio de termos controlados e não controlados, com o uso de operadores booleanos e Descritores em Ciências da Saúde DeCS/MeSH previamente escolhidos. Após a aplicação das estratégias de busca e critérios de elegibilidade, 13 artigos foram incluídos e as características foram coletadas: autor, ano, tipo de estudo, metodologia de diagnóstico de DTM, tamanho amostral, ácido hialurônico utilizado, uso de outros agentes terapêuticos, tempo de acompanhamento e benefícios relatados. A interpretação das evidências obtidas nesse estudo permitiu concluir que o uso de ácido hialurônico em procedimentos de artroscopia é efetiva e pode ser recomendada para pacientes em tratamento para DTMs. Foi evidenciada a necessidade de mais estudos acerca do tema, a fim de estabelecer um protocolo padrão para os atendimentos.

Jacob’s disease or osteochondroma is a rare disease that presents as a pseudo-joint between the coronoid process of the mandible and the posterior surface of the zygomatic bone. The present case report is of an 11-year-old female patient with a maximum mouth opening of 2mm. When evaluating computed tomography with three-dimensional reconstruction, a mushroom-shaped increase in the coronoid process of the mandible on the left side was observed, intimately connected to the zygomatic bone (inferoposterior region of the body of the zygoma), which suggests a pseudoarticulation. Surgical removal of the tumor mass was performed under general anesthesia via intraoral access and is called coronoidectomy. Histopathological, the presence of hyaline cartilage was observed, a condition that is pathognomonic for Jacob’s Disease. Jacob’s disease case reports are still rare in the literature, with mushroom shape and histopathological confirmation due to the presence of hyaline cartilage.

Objectives: This paper aims to discuss some important aspects of surgical planning and treatment of some syndromes with maxillofacial implications. Methods: A case series of five different syndromes with maxillofacial implications was reported. We searched MEDLINE for a surgical approach to these maxillofacial syndromes. PROCESS guidelines have been adopted for the current case series. A Pearson correlation test was performed and considered significant only with a 95% confidence interval. Discussion: The number of publications on the subject of maxillofacial surgery is not related to the incidence of the reported syndromes. Surgical planning and treatment have been discussed in cases of Eagle´s syndrome, Jacob´s disease, Crouzon syndrome, Cleidocranial dysplasia, and Goldenhar syndrome. A brief report of the features of the syndrome and surgical procedures involved were evaluated. Conclusions: Styloidectomy and coronoidectomy are considered the best treatments for Eagle´s syndrome and Jacob´s disease, respectively. For some syndromes, tailored surgical treatment is essential. Some data must be considered in surgical planning and treatment. Depending on one characteristic or another, the surgical procedure can be chosen.
