The marsupialization of a voluminous dentiger odontogenic keratocyst

In 2005, the World Health Organization published the latest classification of odontogenic tumors (1). Within this classification, the odontogenic keratocyst with parakeratosis was called the odontogenickeratocystic tumor and was defined as a "uni- or multilocularintraosseous tumor of odontogenic origin, characteristically lined with a parakatinized type epithelial epithelium with an aggressive potential (1). The treatment of the dentigerodontogenic keratocyst is surgical and consists mostly of cystectomy (5). For large sizes, marginal or segmental marsupialisation or even resection (14,15) is indicated. This article presents a clinical case of a voluminous dentigerodontogenickeratocyst, localized to the mandible that was treated by marsupialization because of the risk of damage to the alveolar vasculo-nervous pack as well as the risk of fracture in the pathological bone if the radical treatment of first intention. After decompression of the cyst, the premise of bone regeneration is created due to the absence of intracystic pressure. One year after marsupialization, we proceed with a radical cure of the cyst and once the bone is healed, the edentation is treated by implanto-prosthetic rehabilitation.
