The odontogenic Keratocyst; evolution of treatment modalities and recurrence rates
Abstract
The odontogenic keratocyst (OKC) is considered one of the more aggressive cysts due to its high recurrence rate, expressed histopathologically by a delicate, friable wall containing small satellite cysts which is often difficult to enucleate from the bone in toto. First described by Philipsen in 1956, this particular entity has evoked much discussion and debate in terms of the treatment options and recurrence rates, in literature. Numerous surgical modalities have been practiced including decompression, marsupialization, enucleation with or without adjunct (such as Carnoy’s solution or cryotherapy) and resection. Having been classified as a cyst of odontogenic origin for over five decades, the designation changed from a cyst to an odontogenic tumour in 2005, and reversed back to a cyst in 2017. Approximately 11 % of all cysts of the maxillofacial region are comprised of odontogenic keratocysts and it is located most commonly in the mandibular posterior region. This paper aims to review the overall recurrence rate of the OKC in relation to specific treatment methods.
