Abstract

Nasolabial cyst is a rare non-odontogenic, developmental cyst that occurs in sublabial and premaxillary area. This cyst is usually unilateral, but it occurs bilaterally about 10% of cases. A 55-year-old woman visited our clinic with asymptomatic bilateral nasolabial swelling. Evaluation of history, physical examination and CT scan led to the diagnosis of a nasolabial cyst, and surgical excision was performed via sublabial approach. In intraoperative finding, two nasolabial cysts of similar size that entirely divided by anterior nasal spine were identified. The pathologic findings were consistent with nasolabial cysts. We herein report a rare case of bilateral occurrence of nasolabial cysts with a review of literatures.
