ACERO SANZ, J.. Keratocysts of the jaw: Resective surgery. Rev Esp Cirug Oral y Maxilofac [online]. 2006, vol.28, n.4, pp.215-221. ISSN 2173-9161.

Odontogenic keratocysts (OKC) affecting the jawbones are clinical entities with typical histopathologic features. OKC are locally invasive showing a high frequency of relapse. Treatment of these cysts remains controversial. Therapeutic approaches are based on two concepts: Masupialization or excision of the lesion. The aim of this paper is to review the existing controversy regarding this topic, focusing especially on surgical excision as a therapeutic approach. Although no clear therapeutic approach has been defined, marsupialization and enucleation have higher recurrence or persistence rates than other methods. Surgical excision of the keratocyst combined with the elimination of epithelial islands in the overlying mucosa, and treatment of the surrounding bone with curettage or chemical cauterization with Carnoy´s solution, offer better results. Radical excision including wide bone margins remains also controversial. This approach can be considered as a therapeutic alternative in aggressive cases.
