Odontogenic keratocysts (OKCs) are benign odontogenic tumors. They have a very high recurrence rate. This study states that in the majority of cases conservative treatment is feasible.

The objective of this study by the International Journal of Oral and Maxillofacial surgery was to describe the authors’ long-term experience with the management of odontogenic keratocysts (OKCs).

All OKC cases treated at the study center between 1999 and 2015, with a minimum of 5 years of follow-up by December 2019, were reviewed retrospectively. Operative procedures including decompression/marsupialization, enucleation (E), E+Carnoy’s solution (CS), E+CS?+peripheral ostectomy (PO), and resection were assessed for complete resolution, partial resolution, and recurrence rates.

The study presented;
--In the parakeratinized non-syndromic group, E+CS?+PO resulted in the lowest recurrence rate among the minimally invasive procedures, while enucleation resulted in the highest rate.

--Regarding the other modalities, recurrence was 12.5% for decompression, 11.5% for marsupialization, 16.7% for E+CS, 26.7% for E+PO, and 0% for resection.

--In the syndromic group, marsupialization resulted in a significantly higher recurrence, while E+CS+PO cases showed no recurrence.

--No recurrence was observed in the orthokeratinized group patients treated with marsupialization or with E+CS.

Based on clinico-radiographic features and observed results, it is concluded that OKC, although having a high recurrence rate, is a benign lesion and responds well to conservative procedures in most cases. Radical procedures should be reserved for unresponsive lesions and those with extensive tissue destruction.
