This article presents a rare case of odontogenic keratocyst involving a linguoverted impacted third molar presenting as orocutaneous fistula. The patient was initially treated with empirical antibiotic therapy with no resolution of the cutaneous fistula and thickening of the skin around the sinus opening resulting in cosmetic deformity. Once the fistula was attributed to the underlying odontogenic cyst, treatment was done by cyst enucleation along with the extraction of tooth and fistula excision.
