remnants of the dental epithelium. With current treatment techniques the recurrence rate is around 2-3% but can be as high as 50%. Recurrence can occur as early as 5 years and as late as 40 years after removal. Recurrence is usually seen within 5 years of treatment. Early findings of recurrence can be easily treated with minor surgery and curretage. Any fragment of the cyst that is left behind has the potential to survive and grow. Therefore, the success of enucleation depends on how well the cyst is removed. Larger cysts have a higher rate of recurrence after enucleation as they are more difficult to remove.
92:) from 2005 to 2017. In 2017 it reverted to the earlier name, as the new WHO/IARC classification reclassified OKC back into the cystic category. Under The WHO/IARC classification, Odontogenic Keratocyst underwent the reclassification as it is no longer considered a neoplasm due to a lack of quality evidence regarding this hypothesis, especially with respect to clonality. Within the Head and Neck pathology community there is still controversy surrounding the reclassification, with some pathologists still considering Odontogenic Keratocyst as a neoplasm in line with the previous classification. 396: 215: 117: 202:. Almost all individuals with NBCCS have odontogenic keratocysts which require numerous treatments. Consideration of the syndrome needs to be taken into account if found in children or if multiple OKCs are present; diagnosis of multiple OKCs in a child necessitates referral for genetic evaluation. Histologically, the cysts are indistinguishable to non-syndromic cysts and over 80% will have 226:. Aspirational biopsy of odontogenic keratocysts contains a greasy fluid which is pale in colour and contains keratotic squames. Protein content of cyst fluid below 4g% is diagnostic of odontogenic keratocysts. Smaller and unilocular lesions resembling other types of cysts may require a biopsy to confirm the diagnosis.

Ostectomy or En – bloc resection: in addition to the above treatments, these may be required due to the issue of recurrence. Ostectomy is removal of peripheral bone.

present they usually take the form of pain, swelling and discharge due to secondary infection. Odontogenic keratocysts are usually noted as incidental radiographic findings. Radiographically they can be seen as unilocular or multilocular radiolucencies. They can be mistaken for other cysts such as
445:. This allows the cavity to be in contact with the outside of the cyst for an extended period of time. Marsupialisation results in slow shrinkage of the cyst allowing later enucleation. However, resolution can take up to 20 months and patients are required to clean the open cavity and irrigate it. 426:

Early odontogenic keratocysts usually do not display symptoms. Typically, clinical signs and symptoms present with bony expansion, or infection. However, bony expansion is uncommon as odontogenic keratocysts grow due to increased epithelial turnover rather than osmotic pressure. When symptoms are

Radiographs of odontogenic keratocysts show well-defined radiolucent areas with rounded or scalloped margins which are well demarcated. These areas can be multilocular or unilocular. The growth pattern of the lesion is very characteristic from which a diagnosis can be made as there is growth and

Recurrence is likely when treated by simple enucleation. Contributing causes include thin and fragile epithelium leading to incomplete removal, cyst extensions extending into cancellous bone, satellite cysts found in the wall, experience of the surgeon, formation of further new cysts from other

As the condition is quite rare, opinions among experts about how to treat OKCs differ. A 2015 Cochrane review found that there is currently no high quality evidence to suggest the effectiveness of specific treatments for the treatment of odontogenic keratocysts. Treatment depends on extent of

spread both forward and backward along the medullary cavity with little expansion. No resorption of teeth or inferior dental canal and minimal displacement of teeth is seen. Due to lack of expansion of the odontogenic keratocyst, the lesion can be very large when radiographically discovered.
341:. The epithelium can separate from the wall, resulting in islands of epithelium. These can go on to form 'satellite' or 'daughter' cysts, leading to an overall multilocular cyst. Presence of daughter cysts is particularly seen in those with NBCCS. Inflamed cysts show 100:
