It is believed to be derived from remnants of the nasolacrimal duct.
Seen most often in adults in the 4th to 6th decades of life.
It has a strong female predilection. 3:1 female-to-male ratio
It is usually unilateral. Bilateral in 10% cases.
This lesson presents an extraosseous location in the region of the nasolabial fold and can cause swelling in the furrow, alar nose elevation and upper lip projection. The clinical findings of the nasolabial cyst are fairly typical. Patients usually complain of a swelling adjacent to the nose, and sometimes the cyst may be observed on routine examination. The development of swelling in the maxillary buccal sulcus may reach great dimensions, causing discomfort with the use of dentures, breathing obstruction and facial asymmetry.
It is generally painless unless secondarily infected.
The nasolabial cyst is lined by pseudostratified columnar epithelium.
Treatment- Transoral surgical excision.
