MARTINEZ PEREZ, D.. Keratocysts of the jaw: marsupialization. Rev Esp Cirug Oral y Maxilofac [online]. 2006, vol.28, n.4, pp.222-224. ISSN 2173-9161.

The odontogenic keratocyst is a tumor-like cystic with a capsule that is formed of squamous epithelium originating from dental lamina or from primordial odontogenic epithelium. Radiologically, radicular resorption is rare. The most important differential diagnosis is the follicular cyst that has a characteristic squamous coating of a variable thickness. Treatment for odontogenic keratocysts is the object of constant discussion as the rate of recurrence published is high (around 30%). The standard treatment is enucleation, but given that the capsule is very fine and friable, it tends to break into fragments during extraction. Incomplete resection of the capsule, as well as the presence of microcysts in the surrounding connective tissue, makes recurrence or tumor persistence more likely. The alternative is treatment by means of decompression and marsupialization.
