Abstract
Orthokeratinized odontogenic cyst (OOC) is a rare developmental jaw cyst, considered as distinct entity from odontogenic keratocysts as it exhibits a less aggressive behaviour and a very low rate of recurrence. Most commonly occurs in mandibular molar and ramus region, rarely seen in maxilla and mandibular premolar area. But till now never reported in condyle, this article describes a case of OOC involving the mandibular condylar head in a 41-year-old male. The initial clinical diagnosis was given as TMD based on the clinical features, but radiographic evaluation revealed osteolytic lesion in right side condylar head. Condylotomy was performed and the specimen was sent for histopathological examination. A definite diagnosis of OOC was made by histopathological examination of the biopsy specimen. We report a rare entity in this article with its management.
