Análise do tecido corado com azul de metileno a 1% e curetado após a enucleação do ceratocisto odontogênico: uma série de casos

Abstract

Various treatments are described for odontogenic keratocyst, including enucleation combined with peripheral ostectomy, which poses the challenge of accurately identifying the extent and location of bone requiring removal. Currently, 1% methylene blue solution is used in the bone cavity after odontogenic keratocyst enucleation to delineate areas for ostectomy. This study aimed to analyze surgical specimens of odontogenic keratocyst and tissue staining with a 1% methylene blue solution after enucleation. Analysis was conducted on 12 surgical specimens obtained from 12 patients, with a mean age of 40.8 years. Odontogenic keratocysts were predominantly located in the posterior mandible (58.3%) with a mean size of 25 mm. In 91.7% of cases, the lesions were unilocular. Bone cortical expansion, cortical bone rupture, and displacement of dental roots were observed in 25%, 33.3%, and 16.7% of cases, respectively. Histological analysis revealed epithelial structures in 75% of cases and in 16.7% of tissues stained with the 1% methylene blue solution. The use of a 1% methylene blue solution after odontogenic keratocyst enucleation appears effective, consistent with findings from previous clinical studies.
