Safety and efficacy of adjunctive therapy in the treatment of odontogenic keratocyst: a systematic review.

Abstract

The odontogenic keratocyst (OKC) is a common cystic lesion in the jaw. Its management, however, is highly debated with no consensus on the best treatment option. Clinicians base their approach on treatment efficacy and associated morbidity. Management often consists of enucleation with peripheral ostectomy and adjunctive therapy to prevent recurrence. The aim of our systematic review was to evaluate the safety and efficacy of these different modalities. Embase, Medline, and Cochrane were searched according to the PRISMA guidelines for articles that presented non-syndromic patients with histopathologically confirmed OKC treated with 5-fluorouracil (5FU), Carnoy's solution (CS), or modified Carnoy's solution (MCS) as adjunctive therapy after enucleation and peripheral ostectomy. The outcomes of interest were safety (measured as adverse events) and efficacy (expressed as recurrence). Risk of bias was evaluated using the Newcastle-Ottawa scale. Four studies were included and 62 patients were evaluated. The results show that recurrence occurred only in patients treated with MCS. Reported adverse events were mostly limited to paraesthesia that could be permanent (in the CS and MCS treatment groups) or transient (across all adjunctive therapies). With the prohibition of CS, both MCS and 5FU are promising replacement adjunctive therapies. From a safety and efficacy perspective we consider 5FU, which was associated with the lowest recurrence and fewest adverse events, to be the most viable option. More high-evidence prospective studies, such as randomised controlled trials, with a longer follow-up period are necessary to draw definite conclusions.
