Background:
The purpose of this study was to determine if 2-stage conservative treatment (decompression followed by enucleation) of odontogenic keratocysts reduced the rate of recurrence compared to single-stage conservative treatment.
Methods:
This was a pooled cohort study composed of both patients identified at our institution and cases reported in the literature. The primary predictor variable was treatment modality (single versus 2-staged conservative treatment). The outcome variable was the overall recurrence rate.
Results:
A total of 684 patient cases were included in the final pooled sample. The mean age was 39.80years (range: 7-80 years). The mandible (76.8%) was the most common site, with the rest of the lesions manifesting in the maxilla (23.0%). A total of 58.1% of the lesions were unilocular, whereas the remaining 41.9% were multilocular. Two-stage conservative treatment demonstrated a lower recurrence rate (14.5% versus 22.1%; P = 0.029).
Conclusions:
Decompression is known to reduce lesion size and optimize the favorability of conservative treatment. Furthermore, we propose that 2-staged treatment may also be associated with a lower recurrence rate.
