Zhou J, Wang L, Chen Z, Qiu J, Dong Q - Oncol Lett (2014)

Bottom Line: Keratocystic odontogenic tumors (KCOTs), formally known as odontogenic keratocysts, are benign developmental tumors that are found primarily in the mandibular molar region and ascending ramus.Recurrence has not been observed within the eight-month follow-up period.The present study discusses the clinical features and surgical management of this case.

ABSTRACT
Keratocystic odontogenic tumors (KCOTs), formally known as odontogenic keratocysts, are benign developmental tumors that are found primarily in the mandibular molar region and ascending ramus. The disease is characterized by aggressive growth and a high recurrence rate following surgical treatment. The present study reports the rare case of a 25-year-old male with a giant KCOT involving the right zygoma, maxillary bone and maxillary sinus. The tumor was removed using a modified treatment of enucleation, grinding and cryotherapy. Recurrence has not been observed within the eight-month follow-up period. The present study discusses the clinical features and surgical management of this case.

Mentions: Under general anesthesia, the lesion was enucleated as a whole, using the Caldwell-Luc approach. The tooth that was associated with the lesion was simultaneously removed to avoid tumor fragmentation. Histological examination during the procedure identified a cystic tumor. The wall of the cyst was lined with a stratified squamous epithelium and a corrugated keratinized lining (Fig. 2). A diagnosis of KCOT was determined. To eliminate the possibility of residual cystic tissue, the margin surrounding the lesion was ground and then frozen with liquid nitrogen three times. Prior to the freezing of the surgical site, the adjacent tissues were protected using dry gauze pads. Subsequently, the patient exhibited a good recovery and no recurrence has been observed within the eight-month follow-up duration.
