The nasolabial cyst is a soft-tissue cyst, nonodontogenic in origin that occurs in the sublabial area and anterior maxillary region. The nasolabial cyst is a rare lesion found behind the ala nasi, extending backward into the inferior meatus of the nasal cavity and forward into the labio-gingival sulcus. The patient with nasolabial cyst often presents with painless swelling and sometimes nasal obstruction. The diagnosis of nasolabial cyst is usually diagnosed in an early stage due to cosmetic facial deformity. The final diagnosis of the nasolabial cyst needs a correlation of the clinical presentations, surgical findings, and histopathological information. There are several treatment options described for the treatment of nasolabial cysts. The current treatment of choice for nasolabial cyst is complete excision through sublabial approach. The postoperative complications may include facial/perinasal swelling, facial numbness, and toothache. The postoperative chance of recurrence is rare. The objective of this review article is to familiarize the readers with this uncommon clinical entity such as nasolabial cyst with its prevalence, etiopathology, clinical presentation, diagnosis, and treatment.
