Acesso transnasal para marsupialização de cisto naso-labial: relato de caso Transnasal Approach to Marsupialization of the Nasolabial Cyst: Report of a Case

5 ABSTRACT The nasolabial cyst is a rare nonodontogenic cyst of slow progression which, depending on its size, can cause facial asymmetry. It is commonly and successfully treated by enucleation, using an intra-oral approach. There is a potential risk of an oronasal fistula when this modality of treatment is employed, owing to the proximity of the cyst to the nasal mucosa. Transnasal marsupialization can be an option in the treatment of the nasolabial cyst as there is a lower risk of formation of an oronasal fistula. The present paper reports a case of nasolabial cyst treated by marsupialization, using a transnasal approach. Descriptors: Nonodontogenic cysts; oral surgical procedures; oral pathology.
