Nasoalveolar cysts: a review of two cases.

Nasoalveolar cysts, also referred to as Klestadt's or nasolabial cysts, though well-recognized, are very rare. Patients with these nonodontogenic cystic masses may present to the otolaryngologist-head and neck surgeon with either intranasal, gingival, or perinasal soft-tissue complaints. The congenital nature of these soft-tissue cysts necessitates that the clinician be aware of the embryology of these lesions when planning a surgical approach to their removal. The authors present two such cases, both in middle-aged females, with left-sided nasoalveolar cysts, who presented to the senior author's practice within 1 month of each other.
