A hiperplasia fibrosa inflamatória, também denominada de epúlide fissurada, enquadra-se entre as lesões benignas do tecido mole decorrentes de traumas crônicos, geralmente de uma prótese mal adaptada. Essa lesão acomete preferencialmente o sexo feminino, adultos de meia idade ou mais velhos, e usuários de próteses. É mais frequente na região anterior da maxila, exofítica, e pode variar de flácida a consistente. O presente trabalho relata um caso de hiperplasia fibrosa inflamatória, diagnosticado em uma mulher de cinquenta dois anos de idade, leucoderma, no ambulatório de Estomatologia I da Faculdade de Odontologia da Universidade Federal da Bahia, e apresenta relatos da literatura a respeito dessa lesão.
A case is reported of a 43-year-old female patient presenting bilateral osteochondritis dissecans (OCD) of the temporomandibular joint (TMJ), in different stages for each side, associated with avascular necrosis (AVN) of the right condyle. Additionally observed was anterior disk displacement without reduction for both sides. We have proposed an adaptation of the previous classification of OCD for cases affecting the TMJ. We have also stressed the fundamental role of panoramic radiography on the diagnosis of stage 3 and stage 4 OCD of the TMJ. In relation to MRI, we have recommended sagittal (slice thickness of 2 mm) and coronal (slice thickness of 1 mm) fast spin-echo proton density-weighted sequences to better identify bone lesions (stage 1 and 2) and also localize osteochondral loose bodies; and coronal (slice thickness of 1 mm) fat-suppressed fast spin-echo T2 weighted sequence to better evaluate OCD (stable or unstable) and the features of the occasionally associated AVN (acute or chronic).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
