Correct answer: BComplete removal of the cyst lining with peripheral ostectomy or application of Carnoy solution to the cyst walls

OKCs have a high recurrence rate (25-60% after simple enucleation) due to the thin, friable cyst lining that is easily left behind during surgery, satellite (daughter) cysts in the cyst wall, and the intrinsic proliferative potential of the epithelium (PTCH1 mutations in some cases). To reduce recurrence, complete enucleation with peripheral ostectomy (mechanical curettage of the bony walls) or chemical cauterisation of the cavity with Carnoy solution (which fixes residual epithelial cells) is recommended.
