PINTO, Gustavo Nascimento de Souza et al. Marsupialization as definitive treatment of odontogenic cysts: report of two cases. RFO UPF [online]. 2015, vol.20, n.3, pp. 361-366. ISSN 1413-4012.

Objective: Marsupialization is a treatment option for cysts, which a surgical window communicating with the oral cavity and sutured along the adjacent mucosa is performed for the progressive emptying of the internal content of the lesion, resulting in its decompression and consequent size reduction. By definition, the technique is followed by a second surgical time for the resection of the remaining lesion. This article aims to present a literature review regarding the marsupialization technique, and report two cases of odontogenic cysts from different origins, in which marsupialization was performed as definitive treatment with satisfactory results in both cases. Case report: (1) Man, 22 years old, with a well-defined radiolucent area involving the crown of tooth 48 suggestive of a dentigerous cyst. The patient underwent extraction of tooth 48 and marsupialization, with total remission of the lesion. (2) Woman, 38 years old, referred by the endodontist due to the presence of a well-defined radiolucent lesion with radiopaque halo in the periapical region of tooth 21 suggestive of a cyst with inflammatory origin. Marsupialization was the treatment selected, resulting in bone repair and lesion remission. Final considerations: Marsupialization as a definitive treatment for cystic lesions is an approach that reduces patient morbidity, and preserves noble anatomical structures, but such topic is rarely addressed in the literature. It is worth noting that this isolated procedure is not predictable and the outcome of each case should be evaluated.
