What is the treatment of odontogenic keratocyst?
Treatment of odontogenic keratocyst (OKC) is one of the highly controversial protocols among oral and maxillofacial surgeons. Treatment modalities range from simple enucleation in the case of lesions that are less than 1 cm to extensive resection in the case of cysts that extend into the skeletal base.
How are odontogenic Keratocysts removed?
Multiple surgical approaches were introduced including decompression, marsupilization, enucleation with or without adjunct (Carnoy’s solution, cryotherapy), and resection. Depending on other studies KCOT can be conservatively treated with enculation and application of Carnoy’s solution or cryotherapy.
Are odontogenic Keratocysts painful?
When symptoms are 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.
Why do odontogenic Keratocysts recur?
The odontogenic keratocyst (OKC) was first described and named by Phillipsen in 1956. It is one of the most aggressive odontogenic cysts of the oral cavity. OKC is known for its rapid growth and its tendency to invade the adjacent tissues including bone. It has a high recurrence rate of 16 to 30%.
What causes odontogenic Keratocyst?
Odontogenic keratocysts (OKCs) are generally thought to be derived from remnants of the dental lamina (rests of Seres), traumatic implantation or down growth of the basal cell layer of the surface epithelium, or reduced enamel epithelium of the dental follicle.
How is OKC treated?
Based on extensive research, recommended treatment modalities for OKC that are known to reduce/prevent recurrence include enucleation, excision of overlying mucosa followed by application of Carnoy’s solution, marsupialization/decompression followed by cystectomy, and mandibular resection.
What causes odontogenic keratocysts?
Why do odontogenic keratocysts recur?
Which cyst has highest recurrence rate?
The odontogenic keratocyst is known for its high recurrence rate and local aggressiveness. It has been classified into two histologic variants: orthokeratinized or parakeratinized.
Which cyst has the highest chance of recurrence?
Botryoid odontogenic cyst (BOC) is considered as a variant of the LPC, with different radiographic features and higher risk of recurrence (3-15).
Is OKC a cyst or tumor?
The odontogenic keratocyst (OKC, currently designated by the World Health Organization as a keratocystic odontogenic tumor) is a locally aggressive, cystic jaw lesion with a putative high growth potential and a propensity for recurrence.
