Abstract

Objective: To evaluate the cases in which patients presented PVNS in the TMJ, including clinical, imaging, histopathological and treatment aspects. Methodology: This is an integrative review with data obtained from the SciELO, PubMed, Medline and Lillacs databases between 1982 and 2021, using the descriptors: “Case report”, “Temporomandibular Joint”, “Pigmented Villonodular Synovitis”. Inclusion criteria: case report studies, full texts available, languages of publication in English, Portuguese or Spanish. Exclusion criteria: studies without the presence of clinical aspects, reports not located in the TMJ, meta[1]analysis articles, systematic and literature reviews, clinical trials, book chapters, dissertations and theses. Of the 156 results, only 23 made up the review. Results: As a treatment, total resection through open surgery is recommended. The most common symptoms were: chewing pain, trismus, pre-auricular pain, numbness, paresthesia, hearing loss and parotid gland swelling. Conclusion: The imaging findings reveal erosion of the glenoid fossa and condyle, histopathologically, giant cells with hemosiderin deposits, and the recommended treatment, resection via open surgery with subsequent curettage.
