Decompression of Large Keratocystic Odontogenic Tumor: Review of Literature and Case Report

Abstract

Introduction: Decompression followed by enucleation of Keratocystic odontogenic tumour (KCOT) is a recommended conservative approach for large KCOT to prevent injury to the surrounding vital structures, pathological fracture of the mandible and radical resection surgery. On the other hand, this approach necessitates multiple surgi-cal procedures and prolonged follow-up which depends on the patient's compliance and may increase the risk of infection.Case report: A 42-year-old male presented with large right mandibular angle KCOT associated with impacted wis-dom tooth. Decompression, incisional biopsy, and extraction of wisdom tooth were performed under Local anaes-thesia. CBCT, 3 and 6 months post-operatively demonstrated obvious reduction of cystic cavity which allowed for enucleation of KCOT followed by Carnoy's solution application under GA with minimal complications. Conclusion:Decompression of large KCOTs followed by enucleation with peripheral ostectomy or chemical therapy is viable treatment option to avoid invasive resection surgical procedure.
