An Unusual Odontogenic Keratocyst Associated with Third Molar Crypt Near Condyle in an Adolescent: A Case Report

Abstract

Background and Aim: A developing odontogenic cyst known as odontogenic keratocyst (OKC) originates from the remains of dental lamina. Its aggressive pattern of expansion and high recurrence rate differentiate it from other odontogenic cysts. Herein, we describe a large OKC in the mandibular ramus, close to the condyle, in a juvenile patient with a third molar crypt. Age and sex of patient, and size, location, and fast development of this lesion were different compared with previously reported OKCs. Our management strategy aimed to maintain the mandible's natural dentition, form, function, and continuity. Case Presentation: The conservative strategy of marsupialization and decompression, which results in final total clearance of the cystic lesion, is one of the treatment strategies for OKC. Segmental resection, en bloc, and complex procedures are other treatment options. Surgical enucleation of the lesion and subsequent marsupialization were conducted effectively in this case. After a lengthy follow-up, there was no recurrence. Conclusion: A detailed comprehension of the nature of the lesion supported by a strong clinical history and cutting-edge radiography may greatly aid the physician in making the appropriate treatment decision for patient's long-term interests.
