Nasolabial cysts are rare non-odontogenic, extraosseous cystic lesions that commonly present as unilateral submucosal masses in the nasolabial fold, accounting for 0.7% of all non-odontogenic cysts. These lesions are a form of retention cyst. Bilateral presentations are extremely rare. They are typically slow-growing, painless swellings that cause cosmetic deformity and nasal obstruction. Diagnosis is largely clinical, supplemented by radiological and histopathological evaluation. They are managed surgically. We report a case of a young female who presented with a history of gradual, painless upper lip swelling and bilateral nasal obstruction following trauma. Clinical examination and radiological findings were indicative of bilateral nasolabial cysts. The patient underwent excision of the bilateral cysts, and histopathological examination confirmed the diagnosis.
