Odontogenic cysts are classified as cysts that derive from odontogenic epithelium and occur in the jaw‘s tooth–bearing regions. This pathology is treated with cystectomy, marsupialization or decompression of odontogenic cyst.10. We present with a case report of a large multilocular OKC which was treated with FNAC followed by enucleation, chemical cauterization with Carnoy’s solution and a chin graft. In addition to reducing intraluminal pressure in the pathological cavity, this operation allowed the lesion to gradually decrease volume "with a gradual increase in bone apposition" and maintained the adjacent teeth‘s integrity.
