Management and recurrence of keratocystic odontogenic tumor: a systematic review

Abstract

Objectives: The objective of this study was to evaluate the most up-to-date treatment modalities and respective recurrence rates for keratocystic odontogenic tumor (KCOT).

Study design: A systematic review of the literature from 1999 to 2010 was undertaken examining treatment and recurrence rates for KCOT. Four inclusion criteria were defined for articles to then be analyzed against 8 standards.

Results: Of the 2736 published articles, 8 met the inclusion criteria. When merging the data, enucleation and enucleation with adjunctive measures (other than Carnoy's solution) had recurrence rates of 25.6% and 30.3%, respectively. Marsupialization with adjunctive measures produced a recurrence rate of 15.8%, whereas enucleation with Carnoy's solution presented a recurrence rate of 7.9%. Only one resection case had recurrence (6.3%).

Conclusions: The enucleation technique with the use of adjunctive procedures (other than Carnoy's solution) provides a higher recurrence rate than any other treatment modality.
